Triple Glazing
Making you feel warm inside

As homeowners face up to the realities of ever increasing fuel bills, triple glazing will become a progressively more important consideration for fabricators and installers

Triple Glazing

Adding triple glazed windows to a property will improve its energy efficiency. McMullanODonnell’s triple glazed system incorporates a twin sealed unit and our custom designed bead co-ordinates with the contours of the sculptured profile.

A triple glazed standard specification window will allow you to achieve a U-value of 0.8, well ahead of the equivalent typical double glazed option of 1.4 for an A rated window.

The noise reduction benefits will vary depending on glass thickness and prevailing environmental conditions.
