Ideal 4000 Casement

A NEW Contemporary Squareline Profile. Aluskin is a brand new design concept in the UK.

New in the UK, but it’s a proven design for aluplast in Europe. The Ideal 4000 aluskin option offers a true contemporary aluminium exterior, whilst retaining all the warmth and performance from your PVC-U windows and doors.

Foils and colour are key drivers of growth in the UK window industry.

That’s why we have made the Ideal 4000 casement system in 27 foil colour options. All this with a 15 day or less lead-time on special foils, at a cost no others can deliver.

The benefits of the ideal 4000 system

The ideal 4000 system combined with ecotech technology offers great aesthetics with a WER A+ rating to bring one of the world’s most advanced window and door systems to UK fabricators and installers.

See how our Ideal 4000 profile is extruded and then how we apply the aluskin option to the profile.





eco-tech delivers a step-change in the use of recycled material and content in a new generation of sustainable and energy efficient PVC-U windows and doors.

We extrude recycled and virgin material simultaneously through a single dye to create a single profile. This locks recycled material away from areas of the frame visible to the end-user or which perform a structural role.

It allows us to utilise a high percentage of recycled content but to guarantee surface appearance, finish, quality and depth of gloss. The surface is perfect – no pits, no extrusion lines.

With an A+ rating for material type from the Building Research Establishment in its Green Guide, it makes the eco-tech among the UK’s most sustainable window and door system options.
