Securiframe products are manufactured to strict quality-controlled tolerances, proven by ISO9001 and ISO14001 certification, for your complete peace of mind.

Our products are also BBA-certified, which means they conform to standards recognised across the construction industry for guaranteeing agreement from specifiers, Local Authorities, insurers, and building inspectors. In fact, our products are the only 100% post-consumer recycled UPVC cavity closers to offer the assurance of BBA certification – meaning you can relax in the knowledge that you’re working with the best-designed products and sustainable materials.

An essential component

Cavity closers are without doubt the simplest and most effective way to ensure cavities around any openings are thoroughly sealed. Our 100% post-consumer PVCU cavity closers deliver optimum performance in SAP calculations and achieving low U-values. They provide a rigid template for bricklaying and the fitting of windows, doors, skylights and other apertures.

We only use Cavalok profiles – the market leader in cavity closer, window subframes and window former systems – and we trust them to deliver components that perform to a standard that always impresses, whatever the project.
