Retrofit Double Glazing & Total Replacements

Retrofit Double Glazing

Double-glazing helps save energy costs through maintaining the internal temperature climate no matter what happens outside. It works on the principle that two layers of glass surround a layer of air between them. This means that in winter the heat from the outside stays outside and the temperature below freezing stays outside. Between the panels are spacers made of polymer strips that act as separating elements. It often contains a desiccant that removes the moisture trapped in the air space. Our polymer strips are more efficient than the standard spacer materials you are accustomed to.

What is the process?

It involves installing new energy-efficient double glazed units into existing window frames that previously held single glazed units. The process includes slight modifications to the frames, such as changing timber or aluminum beads to fit the new glass.
However, these modifications are subtle and do not greatly change the aesthetic of the existing windows. This ensures that the final result maintains the original look, but with better insulation performance so that you and your family are comfortable all year around.

Total Replacement of Windows & Doors

The total replacement of your windows and doors can dramatically transform the look, feel, and function of your home.The existing joinery is completely removed, and replaced with new windows, doors, and framing, so you can completely change the colour, style, and design of your windows and doors.

What are the key benefits?

  • Adds value to your property
  • Enhances the aesthetics of your home
  • Improves energy efficiency due to optimal thermal performance
  • Noise reduction due to better soundproofing
  • Keeps your family healthy and comfortable all year long by preventing drafts
