Getting warmer with an innovative idea.

Roof insulation jobs really showcase the strengths of CALOSTAT®, which is sustainable, non-combustible, pressure resistant, and delivers outstanding insulating properties regardless of temperature. 

CALOSTAT® has been approved as an insulating material for use under a waterproof barrier (“warm roof”) as described in DIN 4108-10, application DAA. Wherever good thermal insulation is needed, warm roofs offer a major advantage: the insulating material does not sit in water, which allows it to insulate much more effectively. This means that CALOSTAT® makes very thin structures possible. A lean, effective insulation option that meets Germany's EnEV energy-conservation ordinance is now available for roof-top terraces, especially in buildings with recessed, staggered floors. 

The use of CALOSTAT® makes a great deal of sense, not just when adding floors to a building to increase housing density in urban areas, but also when renovating roof-top spaces and insulation. Using conventional insulating materials often means having to add structural elements by expanding an attic, for instance, or by raising the edge of the roof—techniques that are not generally necessary in projects using CALOSTAT®

Direct sunlight on roofs easily results in temperatures over 70°C, making the ability of CALOSTAT® to insulate regardless of the temperature a major advantage. Whether insulating at 10°C or 100°C, CALOSTAT® has a λ value of less than 0.020 W(m·K). Only CALOSTAT® can do that. 

Because it is non-combustible, CALOSTAT® can also be used on the roofs of buildings that have to meet tough fire code specifications (as is the case with buildings over 22 meters tall or public gathering areas).

Because it is entirely recyclable and long-lasting, CALOSTAT® is also an answer to a number of sustainability issues. The first roof sheeting manufacturers have now developed warm roof systems that can be easily uninstalled and recycled, and CALOSTAT® insulating materials play a key role in these systems.
