State-of-the-art security features...

Secured by Design – Our UPVC windows can be designed to meet the Secured by Design standard which ensures they meet the stringent security requirements of this police-recognised standard.

Locking – Our 9-point locking system includes two high compression bolts to prevent the window from being forced open.

Herculean hinge – The hinges can be a weak point on standard UPVC windows. Our UPVC windows use heavy duty ‘Herculean’ hinges which are able to withstand the use of a crowbar to prise them open.
