Our uPVC entrance doors feature super strong profiles that are PAS 24 and Secured by Design accredited. Combined with ultra-secure cylinder locks as standard, these are tested to British Standard TS007 3 star; providing the ultimate in anti-snap and anti-drill technology available today.

Our composite door range act as an excellent burglar deterrent across Sheffield and the surrounding areas, with their polyurethane thermally insulated core coated with a super-strong Glass Reinforced Polyester skin (GRP). Secured by Design accredited, our composites are fitted with multi-point locking systems.

Available in either uPVC or aluminium profiles, both utilize locks and cylinders that are Secured By Design accredited. Our bifolding door range also allows for the option to incorporate a fixed door into the design, for additional peace of mind.

Our window security is second-to-none. From classic casements to sensational sashes and tenacious tilt & turn to beautiful bay & bow windows, they’re all covered by the official Police security initiative Secured by Design. Each one uniquely combines high-security frames with quality assured multi-point locking systems, that are fitted as standard.

Available in both durable double and triple glazing solutions, both options provide excellent levels of security. Available in practical uPVC or strengthened aluminium, we install internally beaded windows for added resistance against intruders attempting to access your home from the outside.

The intelligent design of our tilt & turn window range provides further security for homeowners, especially households with young children.

Aluminium window profiles offer a superior level of security, where their standard hardware is sturdier than other window frame materials.
