Energy Rated Doors On Display From Permadoor

Visitors to this year’s Greenbuild exhibition will be able to view some of the first composite doors in the industry to achieve the new Door Energy Ratings (DERs) on the Permadoor stand (C27).

 

The social housing specialist will be showcasing its range of solid and glazed GRP doorsets, which carry the highest A rating under the new DERs scheme.

 

Also on display will be Permadoor’s popular choice of Eco Options; a number of specification choices designed to help architects and specifiers improve the energy efficiency and sustainability of housing stock through improved door performance.

 

DERs are based on a thermal calculation and air leakage data, and provide an independent measure of a door’s energy efficiency. Performance ratings range from A (most energy efficient) to G (least energy efficient) and follow the same ‘rainbow’ scale commonly used on domestic appliances and by the well-established Window Energy Ratings (WERs) scheme.

 

Permadoor’s Eco Options include energy efficient glazing, an innovative recycled Reco22 doorframe system and recycled composite reinforcement. The options can be specified individually or in combination to achieve the desired performance criteria.

 

Visitors to the stand will also be able to view Permadoor’s range of thermoplastic doors, which combine minimal maintenance and high thermal insulation with installation flexibility.

 

Adrian Sunter of Permadoor said: “DERs are a valuable specification aid for architects and construction professionals, who can use the new ratings to evaluate the environmental performance of different door options.

 

“At Greenbuild, we will be on hand to explain the new DERs scheme, as well as provide product information and specification guidance for social housing projects.”

 

As part of the Eco Options, specifiers can choose from Low E glass or warm edge, Low E, 90% Argon filled glazing units, which can deliver an improvement of between 0.1W/M2k and 0.5 W/M2k compared with the standard door glazing specification, depending on the door style and size of the glazed area.

 

The doorframe can also be fabricated from Reco22, which is the first framing system of its kind made from 100% post-consumer PVC-U waste, fully closing the recycling loop. Reco22 was the first window system to be awarded the Building Research Establishment (BRE) A+ rating for all sectors including domestic housing and is now being used in doorframe manufacture.

 

The third Eco Option is a choice of frame and door cill options reinforced with recycled composite material (RCM), as a cost-effective and sustainable alternative to steel or aluminium. RCM is already included as standard in the front, rear and outhouse frame profiles.

 

The original composite door manufacturer and part of the Epwin Group, Permadoor has supplied composite doors to the social housing sector for 21 years. The company’s GRP composite doors replicate the appearance of timber doorsets but offer low maintenance with high performance. Highly resistant to denting, warping and splitting, the doors are secure and durable.
