An uninsulated or poorly insulated building means heat loss, as a consequence we waste money and harm the environment. Proper building insulation is a way to save money and reduce CO2 emissions into the atmosphere.
Blown insulation

STEICOfloc

URSA Pure Floc
Wool for blowing
URSA Pure Floc is the perfect solution for insulating any space, even the most problematic. The product is characterized by quick and easy installation. The innovative formula makes the product safe, odorless and resistant to aging.
The lambda thermal conductivity coefficient for URSA Pure Floc is 0.034 W/(m*K) constant over time, which guarantees excellent heat retention in the room in winter and keeps it cool in hot weather. URSA Pure Floc also protects against noise and effectively reduces the risk of fire occurrence and development (Euroclass – A1 fire reaction class – non-combustible). In addition, glass wool is mostly made of recycled glass cullet and is itself suitable for reuse.
