We Are Glass Experts
Upgrade your window glass and enjoy
a warmer home and lower heating bills.
Keep your existing window frames
EnerGlaze upgrades your windows with the very latest in energy-saving glass. We are Ireland’s leading company in retrofitting and with over 5000 upgrades to date. We are currently retrofitting between 20 and 30 houses per week.
How does an Energlaze glass upgrade work?
First of all, we carry out a free, no-obligation survey and quotation. This allows us to test the type of glass you have in your window frames and make sure they are suitable for a glass upgrade. We offer an upgrade only if you will benefit from it. Occasionally we come across window frames that are in too bad a condition and to upgrade the glass would not make sense. In these rare instances we can offer the customer the opportunity to change their entire window using our glass and a new frame.
Our Low-E-Plus2™ range of heat-retaining glass uses the latest Pilkington technology. This advanced double-glazed unit offers the lowest U-value to suit your existing frames. A U-value is a measure of heat loss. The lower the U-value the better the product is at reducing heat loss. A typical double-glazed unit will have a U-value of 2.8. Our Low-E-Plus2™ unit will have a U-value of 0.9, making it 70% better than regular double-glazing.
