Product catalog summary
Introduction
Hemp blocks are sustainable construction materials offering benefits such as thermal regulation, water regulation, soundproofing, fire resistance, and a positive carbon footprint. They are versatile for various construction applications, including new buildings, renovations, floors, roofs, and interior walls.
Specifications
The catalogue provides details on hemp blocks ranging from 7 cm to 36 cm in thickness, each with specific technical characteristics like thermal resistance, sound reduction index, and compressive strength. These blocks are non-load-bearing and form the insulating envelope of a building.
Applications
Hemp blocks are used in construction systems such as the Hempro System, pole-beam systems, and wood frames. They are suitable for insulating floors, roofs, and interior walls, and for energy-efficient renovations.
Technical Characteristics
Hemp blocks regulate temperature and humidity, absorb sound, and resist fire. Made from natural materials, they contribute to a positive carbon footprint by storing CO2.
Complementary Products
Products like adhesive mortar, HL Mix, HempBag, and ProKalk are used alongside hemp blocks for construction purposes.
Tools and Fasteners
Tools, saws, hooks, and connectors are available to facilitate the installation of hemp blocks.
Masonry Supports
Brackets and angle bars support masonry work involving hemp blocks.
Coatings and Finishes
Various coatings and finishes, including clay base, clay finish, and PCS interior plaster, enhance the aesthetic and functional properties of hemp block constructions.

Hemp blocks Why choose IsoHemp blocks? They regulate the temperature thanks to their ability to diffuse accumulated heat. True thermal buffer; the internal temperature is kept constant and the impact of heat variations between day and night is significantly reduced. 2. Water regulation They regulate humidity thanks to their high permeability to water vapour. They also act as a water buffer, thus providing a constant and healthy indoor climate for the building occupants. 3. Sound proofing They dampen and absorb noise. As true sound dampeners, they allow the absorption or abatement of the majority...
