Standards Information

If windows and doors have been fabricated and tested with Rapierstar screws, can I use alternative fasteners from a different screw supplier?

If alternative fasteners are substituted after fabrication and testing to BSI, PAS24 or other industry standard, new sample windows & doors must be comprehensively re-tested by UK Accreditation Bodies to avoid making your company’s CE Marking and other product certifications void.

What British and European standards do Rapierstar screws conform to?

Rapierstar StarPVCU screws conform to the requirements of BS EN 7412 PVCU window standard, as recommended by the Glass and Glazing Federation (GGF) best practice guide and British Plastics Federation (BPF) fastener guidelines. StarPVCU screws are further corrosion tested “In-House” in accordance with BS EN ISO 9227:2017 and corrosion resistance exceeds grade 4 and 5 according to BS EN 1670:2007.

Rapierstar branded screws also have full declaration of performance to European harmonisd standards and carry CE marking.
