Weatherseal performance really matters, that's why we fit PCE in all our windows.
All our windows feature the innovative PCE weather seals. Offering exceptional performance over a wide temperature range, they don’t shrink or stretch. Instead they retain their original shape year after year to maintain an excellent weather seal.
The unique construction actively absorbs noise pollution, increasing acoustic insulation. Immune to rot, mould, mildew, UV and ozone, CFC-free PCE weather seals will last the lifetime of a window.
