More Benefits

Secondary Glazing

Our design ethos is to focus on giving you beauty and practicality; quiet, warmth, and style. Expertly installed and discreet in appearance, with clean sightlines that don’t overpower your original windows, Secondary Glazing from Reliant Windows offers superb benefits to aged and listed property owners, particularly those in need of some peace and quiet.

From noisy roads to noisy kids, our Secondary Glazing can reduce noise levels up to 80% (54dB), but the benefits don’t end there. A secondary barrier can help to eliminate draughts, condensation can be reduced, and window security is enhanced even further simply by fitting an additional window on the room-side of your existing windows.

Our discreet, yet robust aluminium frames are available in a variety of finishes and colours. Whatever your style of property, we are confident that our windows will deliver sound and energy efficiency, as well as that all-important respect for tradition.

Why choose our Secondary Glazing?



Secondary Glazing products can eliminate draughts and reduce heat loss by up to 65 percent.

Secondary Glazing can be really cost effective in the right applications. Window installations are expertly executed and ongoing maintenance is simplicity personified.
