How It Works

Window Preparation: We begin by removing the existing single pane of glass and a small part of the timber frame to create a precise 15-degree slope. This allows for optimal drainage and ensures a better fit for the new glazing.
Acoustic Seals Installation: Specialised acoustic seals are added to the frame. These seals help block external noise and prevent drafts from entering your home.
Double Glazing Installation: We then install a double-glazed insulated glass unit (IGU), which consists of two glass panes separated by a spacer, filled with an inert gas like argon. This combination significantly reduces noise penetration.
Final Touches: The retrofit is completed by attaching window beading, which ensures everything is securely sealed, and the new system integrates seamlessly with your original window frames.

This process delivers high-performance soundproofing windows while retaining the original look and feel of your home’s windows, offering quieter living without the need for expensive and disruptive full window replacements.
