Hemplith Therm

Hemplith® Therm hemp fiber insulation

are flexible and solid insulation boards made from technical hemp fibers. Our insulation has a high density and the ability to adapt to the different shapes of the building. It is mainly used in a contact of heat and sound insulated systems of walls. The advantages of the panels are very high water vapor diffusion resistance and excellent thermal and acoustic insulation properties. Thanks to these properties, they can completely replace polystyrene, glass or rock wool insulation. Hempltih Therm fit perfectly with the concept of sustainable building

Versatile material for living comfort

Hemplith Therm are insulation mats in 60×110 cm format and various thicknesses made from technical hemp fibers

Areas of application

-Exterior: thermal and sound insulation of walls

-Exterior: thermal and sound insulation of the cladding

-Interior: thermal and acoustic wall insulation

-Plaster base board for interior use

-Insulation for flat roofs with mechanical fastening

-insulation for flat roofs or attics.


Quick and easy to install
No irritation and/or itching during installation
100% recyclable material
Excellent thermal insulation (d = 0.039 W/m.K)
Humidity regulation for a more pleasant living environment
The digestible components of the grass are separated from the fibers during the production process and recycled separately as animal feed.
No offgassing of additives in the living environment – VOC A+
Gramitherm® is easy to cut and can be clamped between roof beams. The regulating effect of Gramitherm® can be used optimally.

Facade insulation board

Thanks to its sound-insulating and moisture-regulating properties, Hemplith Therm is also particularly suitable for facade insulation or roof insulation in houses, apartments, public buildings and offices. Hemplith Therm can be combined in interior construction with Hemplith building boards / lightweight building boards, as well as with wood fiber boards or solid wood. Thanks to their special moisture regulation properties, hemp fiber insulation boards are also an excellent complement to lime and clay plaster.
