That’s why upgrading the glass in your existing window frames makes perfect sense. EnerGlaze Low-E-Plus™ can achieve thermal efficiencies in a double-glazed unit that are 20% better than standard triple glazing when retrofitted into existing window frames. Our double glazing unit retrofitted into the existing window frames will give you a U-value of 1.0 W/m²K.
- A warmer, more energy-efficient home
- No need to change your window frames
- No redecorating required
- Save up to €400 a year on heating bills

What we do - 3 Simple Steps
