The addition of double-glazed units as our standard offering has been a popular change, so that installers can better handle the glass on site. The upgrade to triple glazing is still available for the consumers who wish to have the most thermally efficient option and indeed, the WARMroof triple glazed option is the most thermally efficient hybrid roof system on the market today.  

Importantly, the new double-glazed units have a low U-value of just 1.0 W/(m2K), ensuring that the new rooms in which they are intended for stay warm, regardless of the time of year. The company have also recently standardised a plasterboard finish to the inside reveals of the glazed hybrid elements in the roof, making for an appearance typical to that of a standard extension construction, yet with the benefit of large glazed areas.

Chris Baron, commented:’WARMroof hybrid is the benchmark in terms of roof configurability and overall design. As is the way at Prefix, we listen to the needs of our customers and so the move to a double glazed unit as standard will make on site installation and handling far easier given the weight reduction. However, the 44mm triple glazed unit will still be an option for consumers specifically specifying this option.’
