Breathe Easy?

An overwhelming body of recent research has stated in no uncertain terms the negative impact that poor indoor air quality is having on the nation’s health. Respiratory illness is on the rise and over a third of home are at risk of pollution. Jenny Smith, Marketing Manager at British fan manufacturer Vent-Axia, talks us through the latest research and what can be done to alleviate the problem.

The Royal College of Physicians have just published the report “Every breath we take: the lifelong impact of air pollution” which starkly sets out the dangerous impact air pollution is currently having on our health. It states that around 40,000 people are dying in the UK every year due to air pollution, costing more than £20 billion a year. Exposure to indoor air pollutants such as radon and second-hand smoke further add to these figures. The report looks at how factors such as kitchen products, faulty boilers, open fires, fly sprays and air fresheners all impact on indoor air quality. And with health problems such as cancer, asthma, stroke and heart disease, diabetes, obesity and dementia all linked to poor air quality, it is clear that this needs to be urgently addressed in every household.

This new report has brought indoor air quality (IAQ) to the fore once again and backs up the findings of other recent research. The new BEAMA survey “My Health My Home” has revealed that over one third of UK homes are at an elevated or severe risk of having polluted indoor air and follows on from IAQ research by a leading academic at The University of Reading. Professor Hazim Awbi’s report, “The Future of Indoor Air Quality in UK Homes and its Impact on Health”, states the health risks associated with poorly ventilated homes in no uncertain terms.

One of the revelations in this report is that, as new and refurbished homes become ever more air tight to meet the Government’s carbon emission targets for 2050, the number of people suffering with asthma could increase by 80% from current levels. It also states that current building regulations could increase indoor pollutant levels equivalent to the upper end of (and in some cases well above) World Health Organisation recommended limits.

The report suggests that there should be a legal requirement for new homes, and guidance for retrofitted homes, to have an air exchange rate of at least 0.5/hour, to help protect human health. It states that the most cost-effective solution for achieving this exchange rate, whilst still satisfying energy efficiency requirements, is the standardised fitting of effective continuous mechanical ventilation, preferably with heat recovery (MVHR).

Designed to work with the natural air infiltration, continuous ventilation systems control the air path through the home. As a result, they prevent the migration of damaging humidity and pollutants, providing near silent energy efficient ventilation. For new build homes there are continuous whole house Mechanical Extract Ventilation (MEV) and mechanical ventilation with heat recovery (MVHR) solutions which combine supply and extract ventilation in one unit. For refurbishments, there are continuous Decentralised Mechanical Extract Ventilation (dMEV) systems which extract stale air from the home, improving the air quality and preventing the migration of damaging humidity and pollutants. These energy efficient systems are also available with heat recovery. In addition, there are also dMEV single room heat recovery units available. Ideal for existing dwellings, they are low energy and low cost.

Whatever the exposure – EJOT has the anchor

Buildingspecifier offers an insight into the service and fixings solutions offered by EJOT UK Ltd., the Leeds based specialist.

The Met office may be regretting deciding to individually name every new weather front that approaches the UK – at the current rate Storm Zebra should be with us before Easter – though it does underline the frequency with which high winds and driving rain affect the country. Which is why specifiers require the technical support and general savvy of a company like EJOT UK.

Those attending the recent RCI show at Coventry’s Ricoh Arena will have witnessed the diversity of fixing solutions for flat roofing, rainscreen systems and other construction challenges offered under this global brand; but the products are really only part of a holistic, service based technical offering.

We are all familiar with the map detailing the different exposure conditions to which structures are subjected, but it requires real expertise to translate wind speeds into the right fixing patterns and types. Crucially the EJOT range encompasses different options for mechanical and chemical anchors to suit all the common exterior substrates: including plywood, metal sheeting, brick or blockwork masonry and cracked or uncracked concrete.

By engaging with EJOT, contractors and consultants can access the company’s testing capabilities which will confirm the suitability of certain solutions to the location, the height or configuration of the building and the material which a rainscreen system or built –up roofing system is being secured into.

Brian Mack Technical Business Development Manager for EJOT UK Ltd  said “Globally EJOT is expanding its product offering relating to concrete, brick and block substrates: by consolidating our existing brands, through research & development, and from consultation with OEM’s and engineers. We have the products within the range to meet all installation issues into the different substrates, to tackle a wide variety of applications and performance criteria.”

A further example of the latter would be the Trio ‘general application’ anchor for insulation materials, which is aimed at sub-contractors tasked, say, with securing insulation as part of a rainscreen installation. Described by Brian Mack as versatile and reliable as well as being very cost effective, Trio comprises two types of fixing pin, both of which combine with the same high quality sleeve.

Meanwhile, the three Trio components can be used to fix into concrete or clay bricks including perforated types and aircrete blockwork. The 10mm diameter sleeve itself is manufactured from high density polyethylene to create a variable anchor zone, from 30 to 60 mm depth. The glass-reinforced nylon pin is intended to be used for securing lighter weight insulation such as expanded polystyrene back into brickwork or concrete. Then the metal pin will normally be used for heavier insulation types, though still being suitable for lighter EPS material. EJOT Trio then presents a generic, non-system specific product solution.

Also prominent amongst the products showcased on EJOT’s stand at RCI the company was introducing its new HTK-75-2G 75 mm diameter tube-washer, for part-adhered flat roofing installations.

Importantly it meets SPRA guidelines for bonded/mechanical hybrid installations and is suitable for securing insulation back into either ply or profiled steel decks.

EJOT’s technical sales engineers will advise on the correct fixing centres in relation to wind-load calculations, while the tube-washer and threaded fastener not only address cold-bridging concerns, but the telescopic design provides resistance to imposed loads. With the insulation and membrane permanently secured using EJOT’s hybrid solution, the job is completed by folding and heat welding the laps.

With such a comprehensive collection of fixing products to choose from, and technical resources including site testing available to back them up, potential customers need to investigate the EJOT offering fully.

Quality visitors with money to spend

ACR Show hailed a success by exhibitors.

The ACR Show, the UK’s only dedicated event for the refrigeration, air conditioning, ventilation, heating and heat pump sectors took place at the NEC, Birmingham from 16th – 18th February. There was a notable increase in the quality of visitors, with exhibitors reporting multiple leads and orders.

The decision to include h&v companies was a hit with visitors – nearly 30% expressed an interest in ventilation equipment and over a quarter, heating. Heat Pumps accounted for half the visitor number. The demand for air conditioning & refrigeration equipment was as strong as ever. 70% of visitors highlighted air conditioning equipment as an area of product interest. 55% were interested in refrigeration equipment; 41% refrigerants and a quarter, refrigerated display equipment. And they had money to spend too; nearly 40% of visitors had a budget of £200,000 or more.

Global air conditioning giant Gree is currently challenging the status quo in the UK HVACR market with the launch of Gree UK Limited, so there was naturally a lot of interest in what the company had to say at the event. Commenting at the end of a successful first day, sales director Tim Mitchell said: “Today has certainly been productive for us; it appears that decision makers are at the show and are specifically seeking us out.”

Commenting on behalf of Fujitsu, sales & marketing director, Ian Carroll, said: “We were very pleased with how The ACR Show went. This year, we welcomed a record number of visitors to the Fujitsu stand. Our new product ranges were well received and the show presented a good opportunity for customers to meet the team.”

Stanley Handling’s extensive range of powered stair climbers won rave reviews from exhibitors and visitors alike. Designed to safely move items like hot water tanks, boilers, furnaces, gas cylinders, major appliances, plumbing and heating supplies more, the event generated over 100 enquiries. Managing director, Graham Sharp said: “The ACR Show has opened up so many doors for us; we didn’t have a single time waster. It’s just a shame the event is only every two years. We’ll definitely be back.”

In addition to the 100+ companies exhibiting at the show, visitors enjoyed an extensive seminar programme on range of topics that affect their working day. Leading experts shared knowledge and advice in three seminar theatres: the Air Conditioning & Heat Pump Theatre sponsored by GREE; the Refrigeration & Cooling Theatre, sponsored by Opteon Refrigerants from Chemours and the Training & Careers Theatre, sponsored by Toshiba Carrier. Sessions included: Major issues of interest in BIM; Mechanical ventilation with heat recovery for commercial applications; New developments in Refrigerants and more.

Training & Careers was a key theme at this year’s show with the introduction of a dedicated theatre and national skills competition taking place at the event. The new CPD accredited Training & Careers Theatre, sponsored by Toshiba Carrier, covered a range of topics pertinent to the industry including TM44 inspections – reasons and benefits; the new Building Controls Professional Assessment and how it is helping to raise standards in the controls sector; the Index SEI that is destined to replace COP (Coefficient of Performance); the heat pump market and the effects of the government ditching green incentives; the PURR report; major issues of interest in BIM; energy efficiency from an engineer’s perspective and much more besides.

Silvia Romano, a member of the European partnership for Energy and the Environment secretariat addressed delegates in the Training & Careers theatre on the second day of the show. The EPEE represents the European heating, cooling, refrigeration and heat pump industry is very much committed to supporting the implementation of the EU F-Gas Regulation and its ambitious phase-down objectives. That is why EPEE is developing a new tool, the so-called “Gapometer”, aiming at defining a route towards a successful phase down of HFCs in Europe and will identify the biggest risks of gaps between required and actual progress. Silvia said: “We very much appreciated the opportunity to speak at such a key event on the calendar, particularly for UK stakeholders.”

The ACR Show also hosted the national SkillFRIDGE competition for the first time. The competition provides a potential launch pad for apprentices in the sector to compete internationally at vocational skills competition, WorldSkills. In August 2015 Team UK had great success with Chris Baillie (BA Refrigeration Ltd, and South East Regional College, Belfast) gaining silver medal and runner up at the WorldSkills competition in Sao Paulo Brazil.

“The national skillFRIDGE competition allows apprentices studying level 3 RAC to demonstrate their knowledge, skills and emotional intelligence in a pressurised environment,” said national SkillFRIDGE competition manager and lead assessor, Mark Forsyth.

The competition final required the six competitors demonstrate recognised industry skills and deliver on three main objectives. As such competitors had to demonstrate a core ability to follow instructions and solve problems in order to produce a ‘cold space’ at specified temperature and at the same time ensure an energy efficient refrigeration system.
The winner was Ashley Wilson, an RAC level 3 student at South Eastern Regional College (SERC) Northern Ireland and an apprentice for A1 refrigeration Ltd.

Ashley won over tough competition from Chris Hoy (South Eastern Regional College NI), Kaine Finlay (Eastleigh College), Scott Thomson (Glasgow Kelvin College), Adam Hussain (College North West London) and James Hughes (The Manchester College).

Ashley said “I am very proud to have won SkillFRIDGE, and honoured to have been given the opportunity to experience a great event like this, it really helps you think more about the workplace”.

The ACR Show was backed by all of the leading trade associations, including the Institute of Refrigeration (IOR), which also held its annual conference at the show; the Federation of Environmental Trade Associations (FETA); Refcom; the Building and Engineering Services Association (BESA), British Frozen Food Federation (BFFF), Association of European Component Manufacturers (ASERCOM) and the European Heat Pump Association (EHPA).

Chapter House of St Paul’s Cathedral becomes a more ecologically efficient office

Grade II* Listed Chapter House is a striking building sitting adjacent to the iconic St Paul’s Cathedral, it was designed by Christopher Wren and his son and built between 1712-1714.

The building was originally used as accommodation for the Dean and other members of the Chapter. However, after suffering severe damage during the Second World War it was refurbished in the 1950s into offices, and has since been viewed as the administrative heart of the Cathedral.

Recently Chapter House underwent a major revamp to bring it up to modern and ecological office standards. A key requirement was to improve the thermal insulation throughout the building, retaining the buildings heat and reducing energy bills.

As a specialist in the design, manufacture and installation of secondary glazing, Selectaglaze was specified as its tested products can reduce heat loss by up to 50%. This can be achieved by the bespoke fitting of the secondary glazing alongside the use of high performance seals.

A number of Selectaglaze slime line products were used to suit the various window styles and sizes. These units were mainly chosen as the units are discreet, and a reversible adaptation and are accepted by heritage agencies across the UK.

Over 120 units have been installed in six different colour finishes to match the existing frames.

Established in 1966 and Royal Warrant holders since 2004, Selectaglaze has a wealth of experience working in all building types, as well as an extensive range of products to suit all projects.

For further information, literature and test results, please contact Selectaglaze on 01727 837271/e-mail:enquiries@selectaglaze.co.uk or visit: www.selectaglaze.co.uk.

It’s a cover up!

Although modern renovation plasters are a superb alternative to tradional types; don’t overlook the possibilities impervious coverings – along with hybrid and insulated plasterboards. So says Hudson Lambert, director of Safeguard Europe.

Impervious coverings come in a few varieties, yet easily the most popular are meshed cavity drainage membranes. These are attached to walls using special fixing plugs, and then can be plastered over using traditional gypsum, lime or other plasters. Effective as they are, it should be remembered that despite a notional air gap behind the membrane, these systems are not breathable and will drive rising damp further up the wall unless controlled at source using a high specification remedial damp-proofing cream or rod.

More recently, fleeced DPMs are a natural development from meshed cavity drainage membranes. First, a flexible waterproof adhesive is applied to wall, then the fleeced DPM applied over adhesive and, finally, traditional plasters can be applied on top.

These have the same disadvantages as meshed cavity drainage membranes; yet are faster to apply and their lower profile makes it easier to blend them in with existing plaster finishes.

Beyond these two types of membrane are new systems based around ‘hybrid’ plasterboard. The design intention of these is to utilise the convenience of plasterboard, yet enhance it to reliably allow its on walls susceptible to damp. This is especially useful in situations where speed is important (e.g. tenanted properties where decanting may be inconvenient) and decoration can take place as soon as the system is installed (when using dry joints rather than a plaster skim).

Although they are not suitable where wall surfaces are particularly uneven, they are Breathable (except where foil-backed or insulated plasterboard is used) and BBA approved types are available – which acts as reassurance to clients such as local authorities.

Installation is relatively straightforward: water-repellent/salt-disrupting silane cream is applied to wall and plasterboard applied in the traditional way (although water/salt resistant MS-polymer adhesive is used instead of traditional gypsum-based plasterboard adhesive). ‘Synergistic’ chemistry ensures a high strength chemical bond between the silane cream and the MS-polymer adhesive (due to covalent bonding between the silane components of both materials).

While a plaster skim is usually applied over the plasterboard, using a ‘dry jointing’ method allows the fastest results – and means walls can be re-plastered and re-decorated in less than 24 hours.

If required, the system can be used in conjunction with insulated plasterboard. However, as is always the case when using internal wall insulation, certain precautions are required to minimise condensation risk and it will hinder drying out of the wall compared with when standard (porous) plasterboard is used.
