Window Security

Windows, redefined.

Superior Security to Protect Your Home

Your security is of paramount importance to us at Evolution. Each of our timber alternative windows, doors and conservatories are designed and tested to not only look beautiful in your home, but to be highly secure. Our range of solid, sturdy, tested and reliable locking mechanisms and systems are more than tough enough to cope with modern life as well as keep out unwanted intruders.

Research shows that in the UK, burglars strike every 40 seconds. Families with children are likely victims and, in many cases, there is someone at home at the time of the crime and often this happens in broad daylight. You are six times more likely to be burgled without both window locks and double locks or deadlocks on outside doors.

All our windows and doors come complete with comprehensive locking systems with shoot bolts top and bottom. We employ silver-finished steel bolts throughout our security systems, for absolute consistency and effectiveness.

Technology you can Trust

We use high security shoot bolt locking on all window product brands - Storm and Flush, to keep you and your home safe. Our high security window locks engage on three sides of the opening casement to give maximum protection against intrusion. The other side of the opening sash is made secure by fitting security bolts. With all four sides of our side or top hung opening sashes secure you can be assured that your home is fully protected against would be intruders.

We also offer a range of locking handles for extra security on our windows. This adds an extra safety feature for example for top storey rooms accessible by children or the vulnerable.
