We attach great importance to your security and safety
VELUX offers a range of products and accessories with the objective of deferring entrance through the roof window beyond the general safety level. For example, the present range of standard VELUX roof windows can easily be fitted with a safety lock made of steel. You can fit this lock in the frame yourself.
When the safety device is locked, it is not possible to open the sash, but the ventilation function of the window will still work.
