Cavalok won't wilt in the warmth
July 2009
As building sites across the country swelter in 30ºC+ temparature Cavalok cavity closers can be used with the confidence they will not bend in the heat.
Our white, post-consumer PVC-U material is resistant to the sun's intensity and unlike darker profiles will not warp or bend on hot days.
PVCu is a thermoplastic material, meaning that heat is used to shape the product during manufacture, but that doesn't mean it should ever bend in the sun -even on the hottest days of a British summer. Cavalok doesn't use dark gasket offcuts in our recycling process which react so dramatically to heat and Cavalok formers will not distort your brickwork openings.
