A triple glazed sealed unit is 50% heavier than a double glazed unit. Whilst our standard hinges are capable of carrying this additional weight, in the majority of circumstances, sometimes a more heavy-duty hinge is required.
Middleton Glass offer the Trojan 'Mega Egress' Hinges as an optional upgrade for all our triple glazed products, providing a true 'fit and forget' level of reliability whilst offering total peace of mind for homeowners.
Most UK window systems are not designed for triple glazing. Consequently installers are force fitting much thicker 36mm or 40mm triple glazed unit into a frame designed to take a 28mm unit!
The result is that fitters struggle to bead windows, with the units being forced under such pressure they fail, with expensive service calls virtually guaranteed.
The Liniar system has a triple glazing bead that is specifically designed to allow 40mm units to be easily accommodated. It is simple and straightforward to use and eliminates costly service calls.
Our 'Mega Egress' hinges, supplied by Trojan Hardware, are much larger and stronger than standard hinges.
Utilising a 40mm sealed unit, you can achieve U-values as low as 1.0 W/(m2-K).
Specifically designed to accommodate a 40mm triple glazed unit.
