High Security Sliding Sash Windows

All our sliding sash windows have high security locks and sash buttons to ensure all the hardware achieves an authentic feel. These locks intelligently integrate into the window frame to ensure they aren’t exploited by any would-be intruders. Our windows minimise security weakness spots across the design.

Due to modern techniques, all our sliding sash windows use premium grade uPVC to ensure they maintain their structural integrity. This means that they can achieve an impressive degree of inherent robustness and rigidity. This then enables them to withstand prolonged attacks, therefore allowing you to enjoy peace of mind in a stylish way.

Keeping your family and home safe is of the utmost importance to us here at Select Products. To ensure the highest level of security to children in your home, we offer additional restrictors. These additions can be fitted to all our sliding sash windows. These fully prevent the bottom sash from opening, allowing you to enjoy the traditional style of our elegant windows worry-free.
