Deventer SP5920 Twin Blade/Sliding Sash Seal (96m)

The SP5920 Flipper Seal from Deventer. Used to improve the performance of sliding sash windows, the SP5920 is made from a high-quality anti-friction TPE with no brushes to wear, providing a longer-lasting smooth sliding sash.

The hollow, micro foam chamber ensures no water absorption is possible and provides superior protection from wind with no window rattle, while also protecting against water ingress.

By incorporating a hollow chamber, the seal enhances the acoustic and thermal properties of the window, allowing A rating to be achieved.

The unique design of the SP5920 provides a 2-in-1 sealing action seals along the front and side rail of sliding sash windows, meaning less seals to install and speeding up the manufacturing process.

The seal’s rigid back easily fits and grips into the groove, making it quick and easy to install and also prevents the seal stretching or compressing (wavy effects) during operation.

Unlike some traditional draught proofing that is used in sliding sash windows, you cannot see the flipper seal in the finished window which vastly improves the look of your window.

The Deventer SP5920 is a Cradle to Cradle certified seal making it environmentally friendly and fully recyclable.
