The Problem Area of Burglar-Proofing

Your property needs protection. High security windows make break-ins difficult and give peace of mind! Windows are normally the weakest static construction element in a house or business and are therefore the favoured point of entry for burglars and thieves. Modern window technology counteracts these problems and dangers with individual and effective solutions. An investment in high-tech security windows is the most important step in safeguarding your family and property. Find out for yourself.

Optional with “Sun-Stop” coating , stopping 73% of the sun rays (silver colour), 61% (neutral colour) and 55% (blue colour).For a sample window of 4′ x3′ add $ 75.00.
