Ground floor and easily accessible balcony windows represent the primary point of entry for burglaries. Modern hardware standards significantly deter intrusion attempts.
1. Security Hardware Components
- Mushroom Head Bolts & Striking Plates: Interlocking steel mushroom cams prevent forced prying and sash crowbar lifting.
- Laminated Security Glass (EN 356 P4A / P5A): Multiple tear-resistant PVB films keep glass fragments bonded together even after repeated sledgehammer blows.
- Key-Locking Handles: Prevents thieves from puncturing glass near the handle to turn the latch.
2. Routine Care & Longevity
- Lubricate moving perimeter espagnolettes and hinge pivots once a year using acid-free silicone spray.
- Clean rubber compression gaskets with neutral soapy water and apply silicone grease to prevent drying and cracking.
- Clear lower frame drainage weep holes to allow rainwater runoff and prevent condensation pooling.
