Domus Thermal announced as Housebuilder Product Award finalist

Following success at last year’s Housebuilder Product Awards, Polypipe Ventilation is pleased to announce its unique Domus Thermal duct insulation solution is again a finalist in this year’s Best Services Product category.

Domus Thermal is a patented system that significantly improves the thermal insulation of round and rectangular ventilation ducting in domestic properties, thus reducing heat loss and preventing the formation of condensation.

Domus Thermal was developed by Polypipe to meet current Building Regulation requirements as outlined in the Government’s 2010 Domestic Ventilation Compliance Guide. The Guide states that ducting must be insulated where it passes through unheated areas and voids, such as loft spaces, to reduce the possibility of condensation forming, which can lead to unsightly – and unhealthy – mould. The Guide sets a minimum duct insulation standard of =0.04W/(m.K), with a 25mm thickness. Domestic duct insulation products on the market are generally unable to meet this requirement, but Domus Thermal exceeds the standard, with improved thermal conductivity to allow ventilation installers to fully comply with Part F 2010 Building Regulations.

Domus Thermal has also been recognised by the LABC for this same purpose, as well as for use to insulate rigid ducting passing between the MVHR (Mechanical Ventilation with Heat Recovery) appliance and external terminals; essentially in the heat area of a property. Prior to this, only compliant insulation with a vapour barrier was considered suitable for the latter. The latest NHBC guidelines reinforce this usage, stressing the need to avoid condensate forming on the outside of these colder ducts.

Manufactured from silver EPS (expanded polystyrene), incorporating carbon particles to further improve performance, Domus Thermal has high insulative properties. The range is comprehensive and includes straight lengths and fittings for both Domus round and rectangular duct systems. Each section consists of two identical moulded halves that fit snugly around the ducting and simply lock into place using a moulded interlocking feature, negating the need for taping or gluing joints. The straight length sections are also moulded with a cutting guide every 10mm for added simplicity. Such a design not only makes for quick and simple installation but also looks highly professional.

The robust structure and design of Domus Thermal, in addition to the combined strength of the insulation fitted around Polypipe’s Domus rigid duct, makes the system extremely resilient to site handling.

In line with Polypipe’s commitment to sustainability in both manufacturing and its product range, Domus Thermal is an environmentally friendly product, with an ODP (Ozone Depletion Potential) of 0 and a GWP (Global Warming Potential) of =5.

The Housebuilder Product Awards are being held on 2nd July and Polypipe Ventilation is hoping for a successful outcome two years in a row, with the company having won last year’s award with its Silavent Green Line HRX MVHR appliances.
