If you’re embarking on a new build or self build home you will likely be considering the environmental impact and sustainability of your new home.

Whether you’re focussed on reducing your energy bills or the bigger picture of your impact on the planet, your choice of windows and doors can help you to achieve your aims.

Swedish manufactured composite windows offer the best of both worlds. With a high performance, low maintenance aluminium exterior combined with a warm, authentic wood interior, they offer excellent insulation, longevity and energy efficiency.

Westcoast are committed to using only energy efficient sustainable materials that can be recycled or disposed of by environmentally friendly methods.

Composite window are ideal for Eco Homes:

  • Longevity – the external aluminium of Westcoast composite windows provides very significant additional strength and robustness to the overall construction of our products. It significantly reduces maintenance requirements and extends the anticipated service life to over 50 years; thereby reducing life cycle costs. The aluminium parts are manufactured from a minimum content of 15% recycled material and are 100% recyclable at the end of their service life as they contain no thermal break components.
  • Energy efficient– the double and triple glazed sealed units installed in Westcoast windows and doors are supplied with the latest high performance low emissivity coatings, argon gas filling and composite insulated super spacers for maximum thermal insulation performance. Harmful heavy gases such as SF6 are never used in our products.
  • High performance, low heat loss – the Westcoast triple-glazed Design series has U-values as low as 0.9 W/m2k, ensuring minimal loss of heat (the lower the U-value the better the insulation). From June 2022, the U-values for windows and doors in new dwellings must be a maximum of 1.2Wm2. Read more about the recent Part L building regulation changes here: LATEST CHANGES TO PART L BUILDING REGULATIONS
  • PEFC certified wood – guarantees that our timber comes from renewable sources.
  • Environmentally friendly finish – the low maintenance aluminium exterior of our composite windows is finished in a powder-coated colour which is environmentally friendly and virtually pollution free.
  • Sustainable manufacturing – at the Westcoast manufacturing facilities in Sweden, residents and commercial businesses benefit from many years of investment into sustainable energy technology. The local heating system recovers excess energy from industrial activities which is recycled and complemented with local biomass production to heat the whole city. Westcoast waste timber contributes to this renewable energy source. Power generation is principally from Trollhättan’s own hydro-electricity plant, supplemented by local wind farm and solar energy sources with occasional nuclear support at times of exceptional demand.
