Pilkington K glass works in a similar way as it also allows free heat to get through into your building whilst preventing heat from escaping – earning it the label ‘Thermal glass’. This is achieved through the use of specially developed coatings.
On K glass the coating is located on the inner panes surface, on the side pointing in toward the cavity of the insulating glass unit. The coating is deliberately designed so as not to be a good radiator of heat. That way the warmth is not transferred out to the colder outside pane and into the cooler outside air. Instead it is reflected back into your home or business premises interior. So put simply, it allows warmth in easily, but doesn’t let it escape so readily.
The energy efficient glass allows up to 78 % of the natural energy to get into your buildings interior. This is comprised of 66% which passes directly into your premises and a further 12% which is trapped in the window and eventually works its way through to the interior of your office or business premises.
