Introducing: the new foldable system from WeatherFAST

WeatherFAST have been supplying a wide range of high performance Fatra PVC membrane steel in sheet or coil form for many years. By constantly innovating and designing quality products for use on commercial and industrial gutter systems, they have earned the reputation of being market leaders within this field and their business has flourished. Joe Bradbury caught up with WeatherFAST’s Managing Director, Orry White to discuss their new product, WeatherFOLD – which offers clients a smart and effective way of re-lining old, leaky valley/boundary wall gutters.

Q) Orry, can you tell us a little bit more about your new foldable system and how people who specify it in their build can expect to benefit?

Certainly! In all honesty, we believe our new folding gutter system is the best looking and performing product on the market. The simplicity and effectiveness of its design should really appeal to architects looking for valley/boundary gutter solutions. The gutters include 3 hinges and come in 3000mm lengths, with widths up to 1250 wide and come complete with a 75mm built-in flap that joins onto the next gutter via a single weld. Due to its unique design, we don’t actually need to know the exact degree of the wings prior to fitting. In our experience this alone reduces installation times by up to 50% and makes our clients’ lives a lot easier overall. Instead of having to go back and forth with information on the existing roof gutter system or having to make costly amendments prior to installation of the new product, our system simply follows the lines of the existing gutters. No fuss.

Q) How big a role do you think a folding gutter system can play in helping a building achieve its maximum potential?

Commercial and industrial building owners are always looking for a gutter solution that is good value, good quality, quick to install and preferably BBA accredited. They want to fit something reliable that they can trust – so they can forget about it; safe in the knowledge that it is doing its job in the background.

With a 0.6mm steel substrate/1.2mm Fatra PVC chequer plate slip prevention membrane & 25 year guarantee, we believe our new system has the potential to rapidly become one of the market leading products in this field. It is durable, smart looking, low-maintenance, well designed and great value for money, meeting the tough requirements of the refurbishment/retrofit market. If you are looking for a product that is safe, does the job and is in-keeping with architectural design, WeatherFOLD can help you achieve all of these goals… and more.

Q) Are you seeing an increase in usage of WeatherFAST systems within building projects? As architectural trends continuously shift and innovations are made, are folding guttering solutions becoming more and more prominent?

Absolutely, yes. Architects and specifiers are acutely aware of what the latest innovations and technologies are. There has been increasing pressure on them over recent years to utilise products that are eco-friendly, long lasting and low-maintenance. Contractors are also striving to meet modern demands for safer site conditions, and as such safety is paramount in the key decisions they make. By adhering to these strict principles and keeping our product cutting edge in terms of design, we really have gone from strength to strength. Our systems are being used more and more by new customers every day – customers who have seen or heard good things about the solutions we can provide. We believe that ultimately the product does the talking – and the increase in our sales is a true testament to that.

The silent scream

Juliet Woodcock talks to Paul Barrett, Product Manager at ROCKWOOL Ltd, about acoustic issues in commercial and educational buildings.

These days within my local library, there seems to be no issue regarding offering overspill space to the neighbouring crèche and play group, gathered in loud restless circles containing a dozen or more exuberant infants. However, there was a time when such municipal facilities demanded a peaceful environment for reading or cultural enrichment, while the stern voice of a librarian calling “Quiet please!” quelled noise in an instant.

Intrusive noise coming from without as well as within is a fact of modern life, though fortunately, there are companies out there that do care about creating a peaceful environment for us to live, work or learn in, as Paul Barrett – Product Manager at Rockwool, explains: “Acoustics in commercial and educational buildings matter. It’s imperative that ambient noise is kept as low as possible to minimise intrusion and distraction in these environments. It’s no surprise that studies consistently show that quieter classrooms and workplaces achieve better results. Unfortunately, a large number of schools and office buildings in the UK suffer from poor acoustics.”

Paul Barrett asserts that the most serious issue regarding poor acoustics is caused by flanking transfer, and went on to explain: “The noise is transmitted indirectly via paths such as external wall cavities, voids above partitions and internal corridors, or where there are problems of excessive reverberation within the rooms themselves.”

But it is not just the internal environment that should be considered when trying to improve a building’s acoustic performance. Indeed, when refurbishing or specifying a new school or commercial premises, plans to reduce the noise from outside from wind, rain, hail and traffic, as well as playgrounds and sports centres should be included.

Stone wool insulation is renowned for its excellent acoustic properties, its open fibrous structure making it ideal for absorbing and regulating noise in the building for the lifetime of the property.

Paul Barrett continues: “It is also incredibly versatile, with products and systems available to suit a wide variety of building applications. These include metal and standing seam, flat, green and pitched roofs; ground, exposed and separating floors; internal partitions and separating walls; fire protection and fire stopping; HVAC and masonry cavity walls.
“Fully tested to meet the rigorous demands of today’s legislation, stone wool insulation solutions are proven to reduce ambient, impact and reverberation noise in educational and commercial buildings.”

Utilizing ROCKWOOL’s HARDROCK® Multi-Fix (DD) product on a flat roof, for example, as a 0.25W/m2K single layer or 0.18W/m2K dual layer, mechanically fixed roof solution can provide an acoustic performance of Rw 35dB (single) and 39dB (dual layer) and Class C sound absorption. HARDROCK® Multi-Fix (DD) also provides an impressive fire safety rating as a flat roof board insulation with a Euroclass (A1) non-combustible fire classification and LPCB approval (LPS 1181: Part 1 (Ext-A).

My local library was the last bastion of peace and quiet in my town; I used to know I could go there and get away from other people’s noise – including my adorable nephew’s teething tantrums. I would feel rested there, browsing through books, and in the early days of my journalistic career, going through the micro-fiche with the librarian to order tomes for research that would arrive up to six weeks later pre-Internet days ….. Good acoustic insulation in buildings is vital to our health, our capability to work and learn.

Aluminium decking becomes a refurbishment favourite

A manufacturer of patented aluminium open grilles has tapped into widespread demand in the refurbishment sector by offering a more practical alternative to traditional timber decking.

Yorkshire-based neaco has received a high volume of specifications for its unique Techdek system as garden decking, sun terraces, external walkways and balcony flooring. Many architects, designers, landscaping professionals and contractors have been quick to appreciate Techdek’s advantages for refurbishment work: the product is non-toxic, non-combustible, corrosive-free, extremely durable and easy to install without requiring hot works such as welding. A patented swage-locked construction between bars enables high structural efficiency and load-bearing capacity.

neaco’s National Sales Manager, Peter Melia, comments: “We have been attracting a lot of specifications from refurbishment projects which require replacements for timber decking and terraces – Techdek is virtually maintenance-free, which gives it a clear advantage over wood which can be vulnerable to the elements. The erratic British weather can cause wood to expand and contract with fluctuations in temperatures, damaging the fabric of the timber.

“It almost goes without saying that dampness and wood are an uneasy mix. Rain and moist atmospheric conditions are a major cause of decay and deterioration. Regular surface treatment is required to protect the grain. Aluminium decking is an excellent alternative – our grilles are available with a ribbed surface for anti-slip performance. Our advanced manufacturing facilities can even precision-cut bespoke holes in the decking panels to accommodate existing garden features – we can engineer these to outline unique shapes such as the base of tree trunk. The system can be easily recycled with no downgrading of its properties and very little energy required for re-melting.”

neaco has also enjoyed a surge in demand from conversion projects which require balcony flooring for apartments. Techdek is similarly suited to this type of use with grille profiles that provide a generous 74% contact area yet drain water quickly and effectively. It has become one of the product’s most popular applications and neaco have developed another system, Neatdek 188, featuring concealed drainage gaps which provide even greater privacy for balconies by completely obscuring the view from below.

Peter Melia said: “Many residential developments have specified our grilles as an integral part of our all-in-one modular balconies. We offer a range of modular balcony designs which also provide maintenance-free durability and fast installation with all components delivered to site, including grille flooring, handrails, balustrade and glass panel infills. Our experienced team of fitters can carry out construction with minimum disruption to other site activities.”

Techdek was launched in 1972 as neaco’s founding product and back then its original design concept was conceived primarily as an industrial flooring application. However, its high-performance features, adaptable modular design and the natural attributes of aluminium make it suitable for much broader use. With the ability to accommodate a huge range of angles and unusual curvatures, Techdek has gained a reputation as one of the most versatile grille products on the market and has served a wide variety of architectural uses encompassing cladding, roof access walkways, screening, ventilation, bridge cycle/pedestrian ways, staging, balustrade infills and stair treads. Certain profiles have been specifically developed to provide solar shading, either as dual-purpose sunscreen/walkways or a brise soleil only. They greatly reduce the net heat gain (commonly in the order of 20-40%) of sunlight striking tinted or clear windows.

neaco’s diverse product range also includes modular handrail and balustrade systems, Juliet balconies, structural glass and adaptive bathing facilities. All products are backed by a Lifetime Guarantee and the company’s website features a Members Area containing a host of useful design guides and technical files.

Transforming facades with silicone technology

An external wall insulation system is a thermally insulated, protective, decorative cladding procedure involving the use of an insulating material and a render finish. The most common insulating material is polystyrene, others such as mineral wool, polyurethane foam of phenolic foam may be used. The render finish usually consists of a reinforced base coat followed by a decorative mineral or synthetic finish.

The K Rend Silicone Thin Coat range is particularly suitable where lightweight render systems are required, such as an external wall insulation system (illustrated right).

K Rend Silicone Thin Coat products are available in an extensive colour range using the NCS System which helps customers visualise special colours for their project. NCS – Natural Colour System is a logical colour notation system which builds on how humans see colour.

K Rend Silicone TC 15 render holds the prestigious BBA certification, assuring you that vital product safety and performance requirements are met.

Benefits of Using External Wall Insulation:

  • Reduces heating bills by reducing heat loss through walls
  • Thermal efficiency of walls can be increased by up to 85%
  • Help to save the environment by reducing carbon emissions (as you burn less fossil fuel)
  • Reduce condensation (EWI raises temperature of internal walls)
  • Prevent damp & mould: EWI seals buildings from the elements
  • Improve acoustics: hi-density insulation reduces sound transfer

GRP or polycarbonate rooflights for industrial buildings?

Will you see the light?

Since the late 1950’s GRP has been a feature of many commercial, industrial and agricultural buildings across the UK, bringing the free resource of natural daylight into the workplace.
GRP is a strong thermoset material with good impact resistance and consists of, among other components, polyester resin which is reinforced by a glass strand mat.

The success of Filon rooflights resulted in several UK based manufacturers continuously producing GRP. Eventually, this involved the use of alternative plastic materials such as PVC. As a brittle material, this was at times subject to damage due to storms, foot traffic on the roof and UV degradation.

This didn’t stop the efforts of thermoplastic manufacturers to try to compete with ‘Filons’ and other GRP rooflights though and polycarbonate in-plane rooflights were born and have since steadily encroached on the GRP rooflight market. There are many positive attributes to polycarbonate such as it providing high levels of light transmission, being very strong and having a good fire rating. There are however, many aspects that should be considered in rooflight material choice for profiled roof applications and we shall discuss them now.

Thermal movement

A thermoplastic material such as polycarbonate has much greater thermal movement than GRP and over 5 times more than the surrounding steel sheets.

If no allowance has been made for this movement such as oversized fixing holes, it could create some problems particularly around the fasteners such as the sheet cracking and at the end laps with seals potentially failing. It is also possible for rooflights with an insulating box detail, such as those used in composite panel roofs, for the rooflight to expand but find resistance. The material will have no room to move as it will be constrained by the surrounding metal roof panels and so could belly out – bulge out of shape between the purlins.

Light Distribution

Another significant consideration is the type of illumination required in the building. GRP has high levels of light transmission and is also a naturally diffusing product. It will provide an even distribution of natural daylight across the area to create a balanced illumination reducing bright spots, shadows and hot spots.

Thermoplastics like polycarbonate, when used as in-plane rooflights however, tend to be clear or colour tinted. They are much less diffusing and allow more light to pass directly through the rooflight. This can create localised bright spots with solar glare and also hotspots due to the nature of direct sunlight.

The first images show two very similarly constructed equestrian centres but one is fitted with polycarbonate rooflights and the other with Filon GRP rooflights. The images clearly show a very different lighting pattern: the polycarbonate rooflights allow light to pass directly through so that their position is clearly replicated on the floor – even the purlins are casting shadows on the ground; the GRP rooflights in comparison provide a very even light distribution, so much so that there are not even any shadows visible around the horse and rider – the perfect conditions for easily spooked horses.

The second pair of photographs show a supermarket distribution centre, firstly with polycarbonate rooflights and secondly after the rooflights have been replaced with Filon GRP. Again, in the first picture, the position of the rooflights is clearly visible by the bright spots on the floor. The picture with new GRP rooflights has eliminated all of the bright spots and reduced localised internal temperatures without compromising lux levels – much more suitable conditions for storing some supermarket goods and foodstuffs.

The example projects highlight the importance of selecting the appropriate rooflight material. For your next industrial, commercial or agricultural building, please give careful consideration about the type of light distribution required. If an even spread of diffused light, without shafts of light, hotspots or dark corners is preferred, then GRP is likely to be the most appropriate choice.

Refurb proves best for Fife flats transformation

When Fife Council consulted its residents at Broomhead flats in Dunfermline about the future of their homes, the options were pretty clear cut. The three 50-year old blocks of flats had reached the point where they either needed significant investment to bring them up to the current Scottish Housing Quality Standard, or needed to be demolished and replaced with new build properties.

The result of the residents’ consultation favoured refurbishment and, in May 2014, Fife Council’s Housing and Communities Committee gave the go-ahead for this project to begin. A key requirement was to deliver refurbished homes which offer a higher level of protection against fuel poverty.

The multimillion pound project has transformed 216 properties, housed within the three 12-storey blocks. The building fabric has been brought up to a higher thermal standard, utilising product technology which was simply not available in the 1960s. And that primarily involved the £5.1m contract with CMS Window Systems for the replacement of windows, doors and curtain walling, application of external wall insulation (EWI) and replacing balconies.

CMS was appointed as the main envelope contractor after winning the competitive cost and quality based tender. For Fife Council, this helped simplify the procurement process and supply chain from the outset. CMS was able to help develop a specification for the windows, and their appointment ensured consistent quality, trouble free interface integration and clear communication channels – all proving important to the success of this extensive refurbishment project.

Every flat benefits from A-rated, highly insulating windows which are manufactured with Sheerframe lead-free PVCu profiles and feature thermally superior low-e softcoat double glazed sealed units. With a low U-value, the energy rating (WER) of these fully UK-made windows represents a huge improvement in thermal performance.

CMS also manufactured and installed aluminium curtain walling which spans up to eleven floors on each block, enclosing all communal walkways – equating to more than 2,000m2 of curtain walling. This replaced existing steel balustrades and steel screens in communal areas to raise the quality and visual appeal, internally and externally.

A third component to the structural elements was the replacement of balcony enclosures. CMS installed more than 1,700m2 of enclosures created using Windoor System 1000 featuring ‘Light’ glazing systems. Their design gives tenants the freedom to use their balconies all year round.

Completing the transformation of the building fabric, CMS also over-clad the external walls with a mix of insulated render and render only, as required, using mast climbers for safe access and to ensure speedy delivery with minimum disruption. With total wall coverage of more than 11,000m2, this extensive over-cladding work has improved the insulation level of all walls to complement the performance of the windows, doors and curtain walling.

John Rodigan, Senior Manager of Building Services at Fife Council said: “The Housing and Neighbourhood Service of the Council demonstrated great foresight in their decision to invest in the energy efficient measures at Broomhead.

“It’s also no coincidence that one of our most environmentally committed companies won the contract, it’s been the perfect partnership with all stakeholders sharing the same objectives. The result for the Broomhead tenants will be significant in terms of reduced energy costs and increased comfort. These works have made a substantial contribution to Fife’s green agenda as well as supporting local employment and trade apprenticeships – the delivery of this project has been a real triumph for the Council.”

Sika provides long-lasting solution to long-standing 
college roof drainage problem

The exceptional waterproofing and durability properties of Sika-Trocal single ply roofing membrane has proved its worth on a highly challenging project to refurbish a number of roofs at a busy college campus.

MidKent College is one of the largest further education and training providers in the South East with an estimated 8,500 students enrolled at its Maidstone and Medway-based campuses. The roofs on five buildings at its Maidstone campus, housing classrooms, workshops, kitchens, TV studios and staff rooms had reached a state of disrepair due to wear and tear.

With water ponding on the roofs, leading to water ingress, a solution was required. Sika-Trocal S provided the solution. A total of 4,200m2 of 2mm thick Sika-Trocal S was specified by contractor K&S Construction for the project which was carried out during term-time and with minimum disruption to buildings on site.

The application of Sika-Trocal S was designed to minimise the standing water risk and ensure correct falls towards appropriate outlets and hoppers. This was achieved by over-roofing existing roofs consisting of a number of different bases including felt and asphalt.

Sika-Trocal’s vapour permeable membrane was mechanically fastened at the perimeters and around penetrations using the product’s innovative laminated metal disc system. This system sees the membrane fixed to the roof in a single process, ensuring a fast installation, minimising components required and reducing overall project costs. A 120mm thick, high performance rigid thermoset insulation was also applied to improve the thermal efficiency of the buildings. 

Stuart Marris, Manager at K&S Construction commented: “The MidKent College project is one of the biggest in the firm’s history so it was imperative we specified the most reliable product for the job. Because Sika-Trocal S is amazingly versatile and easy to apply it meant we could carry out the work with little disruption and without the need for people to move out of the building.

“Of its many outstanding features, Sika Trocal’s reliability scores most highly with us.

It is vapour permeable so if there is any water trapped in the system it is possible to over-roof the building without having to worry about things such as condensation.”

Offering exceptional waterproofing, durability and a simple installation process, the cold-applied Type S roofing membrane from Sika-Trocal is approved by the British Board of Agrément (BBA) to have a life expectancy of up to 30 years. As well as providing a single, comprehensive solution to the roofs’ drainage issue, it has brought a pleasing, aesthetic uniformity to the campus buildings. 

Combined with an efficient installation that ensures an improved seal, the Type S waterproofing membrane delivers excellent performance and will provide buildings at MidKent College with safe, reliable all-weather protection for many years to come.
