5 Facts to consider when double glazing

If you are considering double glazing your home, here are some important facts:

1. Non-conductive window frames greatly impact double glazing performance

Aluminium is highly conductive and a poor insulator of heat. So conductive in fact, that even if  double glazed, condensation often forms on the aluminium frames, as moist air looks to deposit itself on the coldest surface. 

Double glazing using aluminium compared to non-conductive Thermalframe PVCu frames will experience up to twice as much heat loss, even with the same glazing composition. 

2. Double glazing is not just about two pieces of glass, but rather the gap between the insulated glazing units that counts

The optimal gap to derive benefit from double glazing is between 14-16mm between the two panes of glass. Anything less than this increases the incidence of heat transfer, and anything greater can create convection within the units. Retrofitting solutions are unlikely to provide the necessary 24mm glazing cavity required to support the optimal spacer gap between the 2 sealed panes of glass. Thermalframe is specifically designed to support optimum spaced double glazed units.

3. Seal technology greatly impacts air and water leakage

The seals within the window system greatly impacts air leakage which compromises thermal performance and water penetration. Thermalframe has a co-extruded seal system that is welded to the frame and each other in the corners to eliminate any potential leakage.

4. A multi-point locking system delivers more than security

Thermalframe multiple locking points shoot bolts across the entire length of the windows. This allows sashes to be almost vacuumed tight against the outer frame, vastly improving thermal performance and sound insulation.

5. Fusion welded mitre corners prevent water leakage

All Thermalframe units feature fusion welded mitre corners that to ensure no mechanical separation and completely eliminate the possibility of water leakage at these joins.
