  • Warmer

    A Series 20 window will reduce heat loss by up to 50% using standard glass and up to 65% with a thermally efficient glass (low-E). High performance brush seals will almost eliminate drafts and ensure much greater comfort near the window.  

    The effectiveness of the insulation is measured by U-values, the lower the figure the better the insulation.

    The Series 20 window fitted with simple catch locks and glazed with laminated glass will provide some resistance to forced entry but there is no test standard.
