Every opening, one system.
Alitherm 400

Made here, not bought in

We hold Alitherm 400 profile in the unit, cut it on our own saw, machine it on our own centre and build it on our own benches. No part of your order goes out to a third party and comes back late. If a size needs putting right, the saw that cut it is in the same room as the person fixing it.

Five ways it opens

Fixed, side hung, top hung, tilt and turn, and flush casement, all off one platform. That matters on a whole-house job: you can mix opening types across every elevation without mixing systems, so the sightlines stay consistent from the front bay to the back bedroom.

Where it suits

A thermally broken system for residential and light commercial work. New build houses and flats, refurbishments, schools and offices, and period properties where the look has to be sympathetic but the performance cannot be.

One thing worth knowing

Smart lists tilt and turn as TBA for PAS 24 and for the air, water and wind classes. That means untested at publication, not failed. The other three opening types carry PAS 24:2022. If the job is security rated, ring us and we will go through it rather than let you find out later.

Colour and finish

Powder coating in the standard and non-standard RAL and metallic ranges, plus the named ranges: Naturals, Sensations, Cotswold Creations and Alchemy. Dual colour is available, so the outside can answer to the street and the inside to the room.
