Security You Can Trust
Strong on Protection, Light on Worry
When it comes to your home, safety should never be an afterthought. That’s why every uPVC window and door we install is designed with built-in security features — including multi-point locking, reinforced frames, and anti-lift protection — to keep intruders out and your family safe.
Our systems meet PAS24:2012 security standards and are approved by Secured by Design, the UK police initiative for crime prevention. For added reassurance, we offer child restrictors and advanced locking upgrades for extra peace of mind — especially in family homes.
