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.
Trust the world’s best weatherseal gasket.
- Best acoustic and thermal performance across the widest temperature range
- 99% memory recovery. Retains shap year after year
- Low operating forces reduces wear and tear and gives ease of operation
- Leaves no rigid sprue after welding
- 20 year guarantee
Great performance everytime
The charts show the compression performance and set when compared with competitor gaskets, this demonstrated the recovery of the gasket after compression thus ensuring consistent performance after your windows are opened and closed, particularly if they are left closed for a long time.
Typical test data
The graph shows the weather performance against competitor gaskets and demonstrates that PCE provides less air leakage over a wide temperature range when compared to our competitors.
