Les solutions chanvre pour le bâtiment / Building solutions with hemp

Density : 45 kg/m3 in panels

A high density brings a good thermal phase shift : The heat takes more time to cross a density material with insulation properties and, in this way, you keep a fresh home during summer.

TECHNICOMPACT® is available :
– ONLY AVAILABLE panels (of 45 kg/m3)

Hemp wool® TECHNICOMPACT® have to be implemented in dry, healthy and ventilated area. The implementation of TECHNICOMPACT® is the same as rock wool, in the warm side of the framework. TECHNICOMPACT® is always apply with a vapour retarder. The water vapour transmission rate for materials have to be higher outside than inside your home to let the vapour cross the wall.


Compress the material between two wooden planks and you can use an angle grinder with an iron grinding wheel or with an diamond grinding wheel (work on rocks) to do this, or a specific sharp knife for insulation. Depends on TECHNICOMPACT® density, the width will change :
With density of 45 kg/m3 : cut 1 cm more than the empty spaces on the framework.


the fitting of sheathing around lagging

Let a gap between the insulation product and the masonry.
With a wood backing frame : TECHNICOMPACT® can be stapled each 25 cm on the framework.
With steel framework : TECHNICOMPACT® will be implement in the framework.
Prior to other things, use a double sided adhesive tape and fix it on the steel framework. Apply one side of the double-face adhesive tape and set up the vapour retarder. After this you can reach the air tightness with the floor and the ceiling with glue and others adhesives.

Insulation of walls with wooden framework

TECHNICOMPACT® have to be stapled each 25 cm on the framework.
cut 1 to 2 cm more than the empty spaces on the framework.
After this, stapled the vapor retarder on the wooden framework.
Use more wooden battents to protect the vapour retarder against electrical ducts

implementation on a roof

rafler system in wood – insulation implemented – security

Let and air spage between the under-roof or the rain cap and the insulation product. use rolls or panels in two crossing layers implementation (it depends on the framework of your project).
We suggest to apply from 200 to 240 mm of insulation products in roofs. The vapor retarder is fixed with staples and/or glue (depending on the the of framework: wood or steel) to reach a perfect air tightness.

ceilling implementation


The vapour retarder is strongly recommanded in the warm side of the ceilling. For a efficient acoustic insulation between two levels we strongly advise a thickness from 100 mm to 145mm .


  • Roofs
  • Attic spaces
  • Walls (partitions)
  • Suspended ceillings
  • Internal partitions
