General presentation

Tek 28

Alubel 28 metal sheet profile, insulated with 10 mm thick high density expanded polyurethane

Tek 28 is an innovative roofing element realised coupling a metal sheet with a layer of high-density expanded polyurethane. The insulation layer, which simmetrically follows the profile corrugation, enables to have an insulated product and at the same time can be integrated to the “Alubel 28 roof system”.”.

Rigid expanded polyurethane is the insulating material that, with equal thickness, guarantees the best thermal performances. It’s a product characterised by a closed cell structure and that’s the reason why it absorbs water moderately and it is not subject to transformations caused by compression; furthermore, in general polyurethane insulations offer excellent performances of dimensional stability and thus prove to be suitable for the severest conditions of application.
