Derowerk is the exclusive representative of isofloc in Poland.

Isofloc F is a cellulose insulating material with qualitites which make it a reasonable choice for insulating:

attics,

flat roofs,

ceilings,

sloped roofs,

floors,

external walls and internal division walls.

Cellulose is installed with blow-in method into cavities, closed compartments and on flat open surfaces. There is no thermal ridge, and insulating materiall completely fills any void. It is very fast during installation, where two people are able to insulate a loft 250 sq m within a day's work. And you get passive house standard quality of insulation!

Cellulose is widely used in passive houses constructions, low-energy buildings as well as typical building constructions.

It is certified as ecological product.

Cellulose isofloc F has lifespan of 50 years.

Low lambda value (0,037 W/m*K) and high heat capacity of 2,1 kJ make it a reasonable insulation for lofts, ceilings, floors and walls in concrete and wooden buildings.

10% of chemical additives result in little load on the environment and keep cellulose performance unwavered.

High fire proofing class B s-2, d0 results in 30 -60 minutes fire barrier when cellulose insulation layer is 10 cm thick only.

Cellulose material is resistant to fire, insects and pests. There is no funghi and mould growth.

Isofloc F makes efficient sound insulation. 10 cm of isolfoc F blown between two gypsum boards reduce the noise by up to 51 dB.

Isofloc F has very light installation densities, 25 kg/m3 for flat surfaces, 40 kg/m3 for sloped compartments and 44 kg/m3 for walls.
