DIY Secondary Glazing
We have grown steadily and we are now the largest specialist manufacturer and supplier of DIY secondary double glazing kits in the UK.
We manufacture a full range of high quality, discreet, aluminium secondary glazing systems and provide an extensive variety of options, accessories and extras.
To self-install secondary glazing, we advise that you need to be a competent person with a good grasp of DIY basics. You may need an extra pair of hands to help with large units and, importantly, complete accurate and extensive measurements.
All secondary window units are delivered by prior appointment and are ready for easy installation.
They arrive fully assembled, except on occasion large units may be delivered with the outer frame disassembled (for ease of handling) ready to easily screw back together.
All are fully glazed with pre-drilled fixing locations and shrink-wrapped for protection.

Substantially improves the thermal insulation of existing single-glazed windows – reduces heat loss through the window by around 65% – around 10% more than double glazing
Secondary windows offer an affordable, discreet, highly effective solution to enhancing building security. No external access is required, ideal for multi-storey buildings
Our products complement your home, providing maximum benefits and years of trouble-free service, specified and designed for thermal and sound insulation, additional security and condensation control.
Much of the Granada range has been specifically designed for listed building windows, conservation areas and heritage properties.
Where condensation is a major issue, we often specify secondary glazing with balanced trickle ventilation. This provides a simple, cost-effective, and permanent solution.
