Give your old aluminium windows a new lease on life with Low-E-Plus™ heat-retaining glass
Double-glazing upgrades for
aluminium window frames
We are one of the few companies in Ireland with the skills and resources to successfully upgrade aluminium windows.
We retrofit the latest in heat-retaining glass into your existing aluminium window frames. This will reduce the existing single glazing U-value of 5.8 to a U-value as low as 1.0, giving you an 82% improvement in heat-retention.
If you have double-glazed aluminium windows installed before 2004 they will have a U-value of over 3.2. So EnerGlaze replacement glass will still deliver an almost 70% reduction in heat loss.
In addition to improving comfort, window glass with a high insulating value is less likely to have problems with internal condensation. This is a particular problem with older aluminium and it occurs when warm, moist indoor air comes in contact with a cold surface, such as poorly insulated window glass.
