Permenantly lower you heating costs

With the emphasis nowadays being on the environment and on energy efficiency, cutting down on heat loss from the home with double glazing is the way to go.

There are two options available, re-glazing your existing windows with double glazing units, or replace you old frames with new PVC. The glass in both options would be the same energy efficient K Glass.

K Glass is one of the leading solutions for thermal insulation in th home and in public buildings. K Glass is a low emissivity coated glass which is easily stocked, processed and installed.


K Glass usually forms the inner pane of an insulating double glazed unit. The coating reflects the heat back into the room whilst also letting in free heat from the sun, a process known as passive solar gain. K Glass helps windows to achieve high energy ratings, to demonstrate compliance with energy saving Building Regulations Part L. When combined with the correct frame, be it timber or PVC, using K Glass can help achieve and A or B rating for all windows.

How does it work?


The glass in your window absorbs heat and then radiates it out on the colder (outside) surface. The low emissivity coating is a poor radiator of heat, so the heat absorbed by the coated glass does not travel accross the air gap to the outer pane of the double glazed unit, and does not escape to the outside. Instead, the coating reflects the heat back into the room. Windows which incorporate K Glass units allow heat from the sun through and keep heat inside, making it easier and more cost effective to keep buuildings warm.
