Our ISOLENA Window Filler sheep's wool insulation is made of 100% wool and is renewable, durable, recyclable and manufactured without synthetic additives. ◘ The loose wool fibres are aligned and processed into a wool fleece (=carded) to make the window filler. The wool strand bound with two twisted threads for stabilisation. ◘ The carded wool bands are suitable for insulating and filling hollow spaces in window and door frames, as well as roof windows in the roofing frame. ◘ For the correct installation, fill in the window filler with a scraper. Thanks to the high filling volume, the hollow spaces are ideally insulated as the sheep wool fills up any hollow spaces. ISOLENA insulation materials have the following ecological parameters according to the NaturePlus® life cycle analysis report: ◘ Use of non-renewable primary energy without the non-renewable primary energy carriers used as raw material (PENRE [MJ, lower calorific value]): 23,44 MJ/kg ◘ Global warming potential Total of GHG emissions and CO2 storage (GWP 100 total): 0,83 kg CO2-equiv./kg ◘ Acidification potential of soil and water (AP): 4,63E-03 kg SO2-equiv./kg ◘ Potential for the formation of tropospheric ozone (POCP): 8,04E-04 kg C2H4-equiv./kg ◘ Eutrophication potential (EP): 2,08E-03 kg PO4³-equiv./kg
