Extremely Airtight Building
The building also excels due to exceptional technical characteristics of the envelope which almost reaches extremes. 60 times better air-tightness as normally used in conventional buildings is a technical requirement, and enables the industry to ensure the best quality. All this presents a small revolution regarding implementation and deserves special recognition. The extremely airtight prefabricated building, Etra, is built from a load-bearing steel construction and Trimo’s insulated, fire-proof façade cladding system Trimoterm.
