Polypipe Ventilation is pleased to announce its Silavent HRX-aQ Mechanical Ventilation with Heat Recovery (MVHR) appliance has made it as a finalist in the prestigious H&V News Awards, in the Domestic Ventilation Product of the Year category.

The H&V News Awards, now in their 23rd year, are an annual celebration of excellence, forward thinking and the highest achievements across the building services industry. The awards cover the entire HVAC and building services supply chain. This year’s awards saw a high number of quality entries submitted, so making it onto the shortlist is a major achievement for all concerned.

Polypipe Ventilation believes its Silavent HRX-aQ MVHR appliance cut through the competition because of its ability to intelligently manage air conditions, for maximum homeowner comfort.

Properties come in different design styles, fabrics, locations and orientations, all of which have an impact on their thermal behaviour. Furthermore, occupants’ comfort levels can vary significantly. The HRX-aQ has been designed by Polypipe Ventilation to take these factors into account, matching ventilation rates to the internal environment and occupants’ requirements for maximum comfort, whilst also being the quietest and most compact (from 199mm in depth) Silavent MVHR unit available.

This is achieved through advanced AMIE (Air Management for Indoor Environments) technology including features such as digital humidity control, automated summer bypass and accurate system balancing.

Unlike conventional humidity sensors, the HRX-aQ enables occupants to have direct control over managing the humidity levels in their home to suit personal comfort levels. By accurately measuring air humidity, the HRX-aQ’s extract speed automatically changes from background to boost as the level of humidity increases, thereby providing optimal ventilation performance.

Similarly, the HRX-aQ features advanced bypass control, programmable by occupants based on time or temperature. In standard mode the MVHR units work by warming fresh air drawn into the building using the heat from waste stale air extracted from the kitchen and wet rooms. In conjunction with multiple time controlled bypass options (night time free cooling), the Silavent HRX-aQ also detects when air temperature reaches a pre-set level and intelligently activates the bypass mechanism allowing in cooler, fresh and filtered air.

Control of these features is achieved via a compact Bluebrain control, which also provides homeowners with helpful maintenance reminders for cleaning and replacing filters to ensure performance of the unit is maximised and air quality maintained.

As with Polypipe Ventilation’s previous Silavent MVHR ranges, the new HRX-aQ remains extremely efficient. When used with a kitchen and one wet room, at typical installation, the HRX-aQ provides an 88% heat exchange performance and boasts a very low Specific Fan Power down to 0.66W/(l/s) – providing the property with a lower Dwelling Emission Rate and additional project SAP points.

There are eight HRX-aQ models available to suit a wide range of residential properties, including units with a specialist heat exchanger technology to further improve air quality and provide comfortable humidity levels.

For the third year, Polypipe Ventilation is pleased to announce its win in the Housebuilder Product Awards Best Services Product category; this time for its Domus Green Line, High Efficiency rigid duct bends. The company won the award in 2015 with its Domus Radial duct system and in 2013 with its Silavent Green Line HRX Mechanical Ventilation with Heat Recovery (MVHR) system, whilst in 2014 it was highly commended for its Domus Thermal duct system.

With the move to more energy efficient air tight homes, effective ventilation in residential developments is an important necessity. This has helped evolve whole house, mechanically driven systems such as MVHR. However, if these are to perform efficiently, ducting needs to be an air-tight, quality end to end system, such as Polypipe’s Domus rigid duct systems.

The Green Line High Efficiency rigid 90° duct bends are the latest addition to the Domus range. They provide up to 60% reduction in resistance to air flow within the bend, significantly lowering a duct system’s total pressure loss and therefore overall energy usage. When used as part of an MVHR system, this can also lead to cost savings as certain properties may be able to use a smaller unit than previously possible.

The unique design of the Domus Green Line 90° bends results in reduced air speed through the bend, thus lowering system noise as well as smoothing the air flow, thereby helping to achieve higher air flow rates when required. All of these factors improve home owner comfort as well as making central ventilation systems easier to specify.

Domus Green Line High Efficiency 90° bends are available for use with Polypipe Ventilation’s best selling Supertube 204x60mm and Megaduct 220x90mm rectangular rigid duct systems, ideal for whole-house ventilation applications which require higher air flow rates.

The Housebuilder Product Awards were held at Edgbaston Stadium on the 29th June, where the winners were announced. Steve Heeley, General Manager – Director for Polypipe Ventilation comments, “I’m absolutely delighted we have won this award. It’s testament to the hard work, innovation and desire to advance the ventilation industry that exists within the business”.

Domus ducting has a deserved reputation for quality and excellent technical support, in line with Polypipe’s position in the ventilation market. Polypipe Ventilation is well placed to offer immediate, practical solutions to Building Regulations Parts F & L. The company continues to provide differentiated solutions in the private and social housing sectors, transforming the way developers, specifiers, installers, homeowners and distributors meet emerging environmental standards.

Polypipe Ventilation’s highly efficient, Silavent CMX Mechanical Extract Ventilation (MEV) units with Domus Radial duct systems, have been specified for a new retirement housing development in Fleet, Hampshire.

Keble Court in Church Crookham is owned by Anchor, England’s largest non-profit provider of housing and care for older people. When completed, it will consist of 72 luxury apartments and one guest suite over three storeys, including communal facilities. All apartments will come with high quality fixtures and fittings as well as carefully considered design features, making life easier for older people. These include continuous Mechanical Extract Ventilation (MEV), to improve indoor air quality and environmental comfort by reducing humidity within the dwelling.

The installation of Polypipe Ventilation’s Silavent CMX and Domus Radial ducting is being carried out by building service engineers Heatcare Limited. Heatcare is a long standing Polypipe Ventilation customer and regularly uses its award winning ventilation and ducting systems on projects nationwide.

For the Keble Court development, Heatcare specified the Silavent CMX MEV system due to its performance and slim-line design. At just 125mm in depth and 3.25kg in weight, the CMX is one of the most compact and lightweight MEV units on the market, enabling it to be easily installed into a central location such as a loft, cupboard space or even small ceiling voids. The CMX’s versatile design also means that these units can be easily installed horizontally or vertically, ensuring ease of installation in limited or awkward spaces.

Polypipe Ventilation’s Domus Radial ducting system was chosen to work with the CMX. Richard Bamford, Heatcare Contracts Manager, explains why – “the building is constructed via a fusion frame system, so the Domus Radial semi-rigid ducting was the most appropriate approach to the install – thus saving space. In addition to this, the system is a lot more cost effective on application, in regards to both labour and materials, ensuring a better overall solution in comparison to the other options we considered.”

Unlike traditional ducting systems, Domus Radial duct systems serve each room vent (air valve or grille) by singular or dual Ø75mm semi-rigid duct runs which connect directly to a central distribution system, splitting the air from a slim-line, compact Radial manifold. Domus Radial has been specifically designed for use within whole house ventilation systems and whilst it is much easier to design and install, its benefits also include less air leakage, increased air flow, easier installation and commissioning, as well as elimination of room to room cross talk and a reduction in air noise.

For Heatcare, product quality is only part of the story: “It is always great to receive a first class service where we can request certain specifications and receive a full design brief and optimal solution, as well as offering positive feedback where possible. With Polypipe, we have received this and more.” states Richard. “The product happened to be the best solution on this particular contract and moving forward, it is definitely something we would consider utilising again on future contracts.”

Silavent CMX MEV and Domus Radial systems have a deserved reputation for quality; supported by excellent technical support from a market leading manufacturer and designer. Polypipe Ventilation is well placed to offer immediate, practical solutions to Building Regulations Parts F & L. The company continues to provide differentiated solutions in the private and social housing sectors, transforming the way developers, specifiers, installers, distributors and home owners meet emerging environmental standards.

Polypipe, the UK’s leading manufacturer of engineered sustainable drainage solutions, has seen its popular Ridgistorm-XL large diameter piping system installed as part of a water management attenuation solution for residential developers Kensington Developments.

Situated in the village of Marton, near Blackpool, the Magnolia Point development consists of 45 detached and 38 semi-detached three and four bedroom new family homes.

Due to the layout of the site, there was a limited public open space available to install a suitable attenuation system capable of storing the required stormwater for the development. Polypipe was approached to review the initial site drainage plan and worked alongside Consultant Engineer, Elluc Projects Ltd to design an alternative solution to meet the needs of both a 1 in 30 and 1 in 100 year storm events under Section 104 agreement.

The selected system was required to fit within an area of 1.25km² and store 680m3 of stormwater. In order to meet these requirements Elluc Projects Ltd specified an attenuation tank formed of 482m of Ridgistorm-XL 1200mm diameter SN2 pipe and fittings. Polypipe was able to take into account the site conditions in order to engineer the Ridgistorm-XL system to exact structural calculations. These calculations ensured that the Ridgistorm-XL system was designed to accommodate vehicles onsite, both during the backfilling and post installation.

The modularised system boasted 17 pipe runs as well as 20 prefabricated fittings, including 17 1200mm 90 degree bends, C and F sections, as well as 3 1800mm RIDGISTORMAccess Manholes. The system was connected together with sealing rings, the simplest jointing method which does not require welding, helping to save time during the installation.

Manufactured in Polypipe’s in-house specialist facility, the Ridgistorm-XL system was delivered to site in ready-to-install modular units, allow for easy handling, whilst reducing the need for heavy plant and minimising time and installation cost.

Richard Fox, Quantity Surveyor at Kensington Developments, said: “It was of paramount importance that the attenuation system used could be designed to fit into our limited available footprint. Polypipe’s pre-fabrication facilities meant that the system was designed and delivered to fit. The pre-fabricated fittings also assisted for a speedier installation, and reduced health and safety risks on site.”

Vikki Woodhouse, WMS Residential Manager at Polypipe Civils, said: “We have vast experience in providing water management solutions. The Ridgistorm-XL attenuation tank needed to be designed to fit within the limited space available and so Polypipe’s technical experts were on-hand to advise on the design from the beginning of the project. We were given a very unique project and designed a fully engineered system, taking all of Kensington Development’s requirements into consideration providing expert stormwater for the site.”

The installation of the Ridgistorm-XL attenuation system was completed in September 2015.
