JCP Bubble Gasket Timber Window Door Double Glazing Rubber Seal

The JCP range of Timber Bubble Gasket Seals take advantage of the unique "Slippex" material which gives it high performance, high tear strength, amazing deflection recovery and great acoustic properties. The gasket fits easily into the timber frame sealing it against wind and weather and is completely UV and ozone stable. It is easy to clean and can be used on both the top and the bottom of the sash.

Please note: When buying multiples of 1m, the gasket will then be sent as one continuous length and not several 1m lengths, where possible.

When fitting it is easy to cut the gasket too short - to avoid this measure around the unit and add approximately 6cm to the length required before cutting.

    The gasket appears well made and of a decent quality material. Certainly fits my mahogany exterior door properly.
