Smart Alitherm 300 Range

Clarks Glass Alitherm 300

Each alitherm casement window is crafted to your exact specification and measurements. First we talk with you about your lifestyle, tastes and double glazing requirements. Then we design the casement windows you need to make your home or commercial property just the way you want it.

Latest Technology.

The Alitherm 300 aluminium range uses the latest polyamide thermal barrier technology. This advanced profile technology creates a barrier between the cold outside and the warm inside, keeping you warm and comfortable even in the coldest weather and helping to reduce your family’s energy bills in these tough economic times. The sashes are designed to take 28mm double glazed units.

Finished to perfection.

Our profiles are finished in polyester powder coated paint and are available in a huge range of colours and finishes that includes dual colour, realistic wood structure and metallic finish.

The polyester powder coated paint finish is produced to the highest standards and quality is guaranteed for up to 10 years. We match almost any colour – a real benefit where planning consent may be an issue.
