ISOLENA window filler
Density: 30 g/lfm and 30 kg/m³
Application: Window insulation, joint insulation, doors, timber construction
Our ISOLENA joint tape consists of 100% with Ionic Protect® protected wool and is renewable, durable, recyclable and made without synthetic additives.
- The loose wool fibres are aligned and formed into a wool fleece processed (=carded) to produce the joint tape. The tape is stabilised with two twisted threads bound.
- The carded wool ribbons are suitable for Insulating and filling cavities on window and door frames, as well as roof windows in the area of the flashing. The natural joint tape is a Ecological alternative to assembly foam.
- To install, push the joint tape into the joint with a spatula. Due to the high filling volume, the joint is optimally insulated and the sheep's wool fills every cavity.

Ecological parameters
Our ISOLENA sheep's wool insulation not only impresses with its natural properties, but also with its outstanding environmental performance. The Environmental Product Declaration (EPD) shows that our insulation makes a positive contribution to sustainability in the construction industry. We would like to emphasise the CO₂ balance: Sheep's wool binds large amounts of CO₂ as it grows. This natural carbon storage ensures that our insulation stores more CO₂ than it emits over its entire life cycle.
Total CO₂ balanca: -19,3 kg CO₂ equivalent per m³ → Climate-positive thanks to natural CO₂ storage
All other ecological indicators according to EN 15804 such as GWP total, GWP biogenic, PENRT etc. can be found in the Environmental Product Declaration (EPD).
