New Energy-Efficient Windows & Doors

While our primary focus remains on upgrading the glass in your current windows and doors, there are occasions when some windows and doors are not suitable for a glass upgrade simply because they are beyond repair and inefficient, and to change the glass would give you no benefit. Because of this, we offer NEW windows and doors with our NEW heat-retaining glass.

ENERGLAZE windows with heat-retaining glass

Compare our U-value. A U-value is the measure of heat-loss through a specific material – the lower the better.


ENERGLAZE - Our Promise

Our commitment to you is that we will not try to sell you new windows if we believe you could get equal benefits from just upgrading the glass in your existing window frames. Of course if you want new windows and doors we will be happy to oblige.

ENERGLAZE is the first company in Ireland to adopt this approach.
