Our windows are made from the finest aluminium in a choice of styles - picture or bay, side hung or top-hung casement, in fact any design or combination you require. With diamond or square leaded lights and Georgian glazing bars if required

Aluminium is a naturally strong material. Alitherm utilises this strength to offer slim profiles that are attractive to the eye and produce windows that let in the maximum of light - transforming your home both outside and inside.


Polyamide technology

Aluminium is known for it’s resistance to rust, rotting and distortion but the introduction of polyamide technology takes it to a new level - offering improvements in thermal insulation, increased strength and the opportunity for dual colour finish - different colours on the internal and external faces.


In today’s security conscious world you can never be too careful.

Security in mind That’s why our windows have been designed to meet the standards of BS 7950. Locking handles come as standard and a choice of locking systems are available including multi-point locks with shootbolts for that extra piece of mind.


Comfort and warmth

To keep out those other unwelcome intruders - bad weather and draughts - durable double weather sealing comes as standard on all opening windows (capable of performing to the severest rating required under the British Standard)
