Cellulose Wool – The Perfect Material for Flat Roof Insulation
Since 1988, the Termex® brand has been used to insulate residential buildings owned by housing cooperatives and condominium associations. Our material consistently demonstrates excellent thermal insulation, moisture resistance, and the appropriate fire resistance rating.
These qualities are particularly important when insulating flat roofs where vapor barrier is not present or it is incomplete. Unlike many traditional materials, Termex® cellulose insulation retains its full performance even in conditions of high humidity.
Properly insulating a flat roof is crucial because up to 20% of the building’s total heat loss occurs through the top floor. By using Termex® cellulose, this loss can be significantly reduced during the heating season, while the building is also protected from overheating in summer. This dual benefit has been confirmed by positive feedback from residents on top floors in many completed retrofit projects using our material.
All of this makes Termex® a highly attractive solution for housing cooperatives and building managers seeking effective, long-term insulation.
Over 20 Years of Tradition in Flat Roof Insulation
- Blown-in cellulose insulation has been successfully used in Finnish flat roofs for almost four decades.
- This method is effective, relatively affordable, and minimally disruptive to residents.
- But do these benefits truly guarantee peace of mind for building administrators?
- With modern technology, verifying insulation quality is easier than ever.
- Tools like thermal imaging drones can detect heat leakage with minimal cost and effort.
