Double Glazing your existing windows is as straightforward as it sounds. TwinGlaze replace your inefficient single glass with High Performance double glazing while retaining your existing windows.
TwinGlaze transforms your existing Windows and Doors into Energy Efficient Double Glazed Windows and Doors by removing the uninsulated single glass, upgrading the existing seals and hardware and installing High Performance Double Glazing at a fraction of the cost of full frame window replacement.
Until now, the only way existing homeowners could enjoy the savings and benefits of High Performance Double Glazing was to go down the costly path of a full frame window replacement.
TwinGlaze offers homeowners an opportunity to improve thermal performance, sound reduction and comfort without removing and replacing their entire window frame.

TwinGlaze Technicians carefully remove the existing single glass from the window or door frame. The frame is then prepared for the installation of our High Performance Double Glazing.
TwinGlaze Double Glazing is installed discretely into the existing window frames to maintain the current internal and external visual aesthetic.
The process is neat and tidy as we are simply replacing the glass.
The completed window continues to look as it did before, with the added benefits of double glazing and improved functionality from our complimentary seal and hardware upgrade.

Includes removal and recycling of your existing glass and installation of VacGlaze™, our High Performance Double Glazing into your existing windows and doors.
Sliding Windows & Doors: Includes complimentary replacement of your seals and rollers with thermal and acoustic brush seals and new rollers.
