Secondary Glazing

Secondary glazing, also known as overglazing, involves installing an additional layer of glazing over existing windows. This creates an insulating air gap that significantly improves thermal insulation, reducing heat loss and keeping your home warmer in winter and cooler in summer.

Benefits of Secondary Glazing

Enhanced Thermal Efficiency: Secondary glazing can significantly reduce heat loss, leading to lower energy bills and a more comfortable home.
Improved Soundproofing: The additional layer of glazing effectively blocks out external noise, creating a tranquil environment.
Protection from Condensation and Draughts: Secondary glazing eliminates cold bridges, preventing condensation and draughts, and reducing the risk of mould and damp.
Preservation of Original Windows: Secondary glazing protects your existing windows from damage and deterioration, extending their lifespan.
