Planitherm Glass

planitherm glassAll of the timber windows and doors that you’ll find here at GBS Joinery incorporate Planitherm double glazing which offers the latest technology in its completely new generation of high performance, soft coat low E (emissivity) glass. With the inclusion of warm edge spacer bars and argon gas, GBS are able to reduce cold edge bridging on all of your casement, box sash or sliding sash windows.

Planitherm glass will ensure that your windows are more efficient in keeping your home warm & bright; in fact it has been proven to offer THREE TIMES more efficiency than standard double glazing. Thermal glass coating offers our customers the latest advancements, allowing them to reduce household costs by pushing them further towards the recommended energy saving status.

As Europe’s leading energy saving double glazed glass providers, Planitherm is one of the highest quality products available on the window market. By reflecting radiated heat back into the rooms in your home rather than letting it escape, your property will act as a much brighter and welcoming environment for you and your family to enjoy. Both stylish and efficient, Planitherm is able to capture the natural daylight and allow it to pass through the glass.

Thanks to Planitherm’s advanced thermal insulation, you get 3 times more efficient than single glazed windows. Not only that, these windows are at least 25% more efficient than most double glazed windows.

Timber Quality

Timber being a natural product is prone to defects and as such we endeavour to not only source the best possible quality of timber but to deal with as many of the defects as possible during the manufacturing process.


Factory painting of windows and doors by GBS uses a specialised industry developed and recognised microporous paint system designed specifically for timber windows and doors to provide long lasting protection against weathering and to resist cracking and flaking.

Maintenance and redecoration will be required throughout the life of the product at intervals of between 8 – 10 years for light colours, reduced to 5 – 8 years for dark colours depending on exposure and orientation.
It is advisable to wash down paintwork annually with a mild detergent and soft cloth to prevent the build up of dirt . Do not use any abrasive products.
When re coating use only microporous paints, do not use traditional oil based paints or paints that will seal the surface.
