At J And K Glass, we strive to fit the highest quality windows at affordable prices. Made from the latest design profile and glass we aim to deliver the best standards possible.

Many of J and K's windows are supplied with toughened glass. This glass has gone through a tempering process which involves extreem heating and rapid cooling of the glass, this provides greater strength for safety and has a higher thermal resistance allowing less heat to escape from your home.

Having air between panes in a double glazed unit is necessary for good insulation.
For greater insulation our glass units are Argon gas filled, which is a colourless, non-flammable inert gas. It reduces heat loss by slowing down the convection inside the unit. Argon has a better degredation rate allowing up to 20 years good service.
