Unifloc Cellulose Insulation – 14 kg Bag
Unifloc is a loose, capillary-active cellulose fibre insulation made from sorted daily newspaper paper. As a loose-fill floor insulation, it is ideal for timber joist floors, attic areas and top-floor ceilings: loosen – pour – level. The material creates a near-joint-free insulation layer and supports balanced moisture behaviour.
Your benefits
- Easy to install: no cutting required, ideal for renovation & DIY.
- Excellent insulation performance: thermal conductivity λD = 0.038 W/(mK).
- Capillary-active & moisture buffering: absorbs and releases moisture (sorption capable).
- Tested & certified: ETA/CE, VOC tested.
- Fire behaviour: B2 (DIN 4102); Euroclass E / B-s2,d0.
Applications
- Timber joist floors / intermediate floors
- Attic and loft areas
- Top-floor ceiling (non-trafficable or with suitable covering)

Yield & installation
Loosen the material before installation (e.g. with a rake/fork/mixer) and distribute evenly. Guideline: approx. 2.5–3 bags (14 kg each) per 1 m³. Note: not load-bearing – use only in suitable constructions.
