IDEAL 4000 casement is an example of a group of window systems that open outwards so-called "bevelled \ chamferred", characterized by a flat rebate with one or two oblique planes. The windows in these systems are also eagerly installed in wide residential construction as well as in market segments related to public tenders and architectural services. The advantage of this type of systems, especially those characterized by a single oblique surface of the rebate is a much faster and easier machining process - especially cleaning the rebate.

The development of "bevelled \ chamferred" systems are emerging on the market hybrid systems, combining the advantages of PVC profiles with other types of materials. Until now, most of them have combined PVC profiles with wooden elements. Aluplast, drawing from several years of experience in launching Aluskin aluminum overlays, offers a combination of the advantages of the Ideal 4000 Casement system in terms of thermal efficiency, interior aesthetics and cost of production, external aesthetics and durability of aluminum facades.
