At KJT Builders we offer a range of double glazed windows to suit every property, with windows available in a range of styles, materials, sizes and shapes. We can even fit double glazed tilt and turn mock sash style windows to replace existing traditional sash and case units that have deteriorated in condition over time.

Energy Efficiency 

Windows and doors are a major source of heat loss in most buildings, which in turn leads to increased heating costs. This also increases carbon emissions, since you must burn more fuel to keep the property at the same temperature.

All our double glazing frames are 70mm Duraflex frames, which help to increase energy efficiency. KJT Builders offer highly energy-efficient Pilkington K glass in our double glazing, which has been treated with a special low emissivity coating.

Pilkington K glass has been recognised by the Energy Saving Trust as an effective method of achieving energy efficiency and saving on fuel bills, in line with the energy saving Building Regulations Part L.

Double glazing units containing Pilkington K glass can give up to 30% better insulation than other double glazed windows.

Some double glazing companies in Hampshire advertise very cheap double glazing prices, but then add on a number of extras to reach the final amount that you pay.

KJT Builders believe in offering one straight price which includes all required windows and doors, installation, and the removal and recycling of your old windows. We will also restore your property to the state it was in before we began work.
