Polypipe’s whole-house ventilation systems to be showcased at Ecobuild

Following the recent launch of a number of innovative new products, Polypipe Ventilation will be exhibiting its full range of energy-saving Domus and Silavent ventilation products for the domestic and light commercial markets at this year’s Ecobuild event taking place at London’s ExCeL on 3-5 March.

Products being launched at the show include the company’s Silavent Sapphire intermittent extract fans and decentralised Mechanical Extract Ventilation (dMEV) units, plus two new patent-pending additions to the company’s Domus range of ducting systems in the form of high-efficiency Green Line 90° bends and a plenum with an integral flow control device.

The sophisticated Silavent Sapphire intermittent axial, in-line and centrifugal bathroom and kitchen extract fans are available as standard and Green Line energy-efficient models; these will sit alongside the existing Silavent fan range at the show. The stylish axial and centrifugal dMEV units mirror the same aesthetically pleasing design of the fan range and provide quiet, continuous ventilation to any standalone wet room. Both offer variants that operate with low specific fan powers  to comply with Building Regulations and very low sound levels – down to 12dB(A) for dMEV and 32dB(A) for the intermittent fans.

The new Domus Green Line high-efficiency 204mm x 60mm and 220mm x 90mm 90° bends provide a staggering 60% reduction in duct bend resistance to air flow, lowering the duct system’s total resistance and overall energy use, which in turn may allow a reduction in size of the mechanical ventilation with heat recovery (MVHR) unit and consequently the overall system cost. Also for use with Polypipe’s Domus 204mm x 60mm Supertube rigid duct system is a new plenum with integral flow control device. This new adaption enables the inlet/outlet plenum to be connected directly to a stylish architectural grille – replacing traditional air valves. The plenum also allows for commissioning to be carried out in advance of construction of the finished ceiling - providing peace of mind that the required air flow rates will be achieved and less risk of costly remedial work.

In addition to these new products, enhancements have also recently been made to Polypipe’s Domus Radial systems, which will be displayed at this year’s show. These include a new slim-line manifold, ideal for fitting between joists or in tight spaces, and an outlet plenum with optional twin connection for increased air that is available with an optional integral flow control device to enable the inlet/outlet plenum to be connected directly to a stylish grille. A 250mm-long FireBrake fire-stopping sleeve – to prevent the spread of flames through openings in walls and ceilings made for the ducting – and bespoke Radial semi-rigid duct insulation, to prevent the formation of condensation when the duct runs from warm to cold areas of a property, will also be seen for the first time.

Polypipe’s patented Domus Thermal duct insulation range will also feature on the stand. The range has recently been extended to cover its 220mm x 90mm Megaduct high air flow rigid duct system.

Many of the products new to Ecobuild have been introduced to work as part of a whole-house ventilation solution, in line with wider industry changes towards more sustainable and healthier indoor living environments. Polypipe’s centralised ventilation solutions will be displayed at Ecobuild, including the compact (125mm deep) Silavent Green Line CMX Mechanical Extract Ventilation unit and the award winning Silavent Green Line HRX and HRX2 MVHR range. The HRX2 boasts one of the highest available heat exchange performances on the Product Characteristics Database – previously known as SAP Appendix Q – and has proved highly popular.  

Polypipe Ventilation provides customers with a complete sustainable and specifiable ventilation package, with ducting and appliance working in harmony, to meet the most demanding of energy efficiency targets.

Its product offering is backed by a range of support services, from technical support, website and literature through to BPEC-approved installer training. The company’s full product range and information about sales and technical support are all detailed in its Product Selector catalogue, which will be available at Ecobuild and is now available to download.
