COLLECTIVE HOUSING
Building your collective housing
Multi-purpose insulating structures
Tradical Hempcrete delivers dynamic THERMAL, ACOUSTIC and HYGRIC performance ratings. It is suited to different applications — walls, roofs and screeds — and provides bio-based self-contained insulation.
Innovation within budget
As this product can be mechanically applied, it is very cost-effective, making it a worthwhile solution for tight budgets and project schedules.
Less pressure on foundations
Tradical Hempcrete is an ideal way of lightening the load. Its mass density is 320 kg/m3, whereas for standard concrete, it is 2.2 t/m3. This allows for substantial cost-savings in structure and foundation design.
Adaptable to all load-bearing systems
Whatever the load-bearing solutions chosen for a building — timber, concrete, metal — the multi-purpose properties of Tradical Hempcrete make construction so much easier. Different set-ups can be envisaged: embedded frames or frames that are offset towards the interior or exterior.
The choice depends on the building method and the finishes to be applied.
Showcasing your eco-friendly approach
Buildings designed and built using this approach may be awarded two labels in France: the new low carbon footprint building (BBCA) label and the bio-based building (Bâtiment Biosourcé) label with three ratings (level 1-3). These labels give buildings prestige in a highly competitive market. Our Tradical Hempcretes have met these requirements for 20 years now.
Paving the way
37 rue Myrhra, Paris, France
NXNW architects boldly decided to use a metal load-bearing structure. This solution enabled the project to progress more quickly with shop pre-fabricated frames. This made in-situ assembly easier, limited road traffic disruption and
produced a lighter building to compensate for the fragile nature of the ground; 150 m² of opaque walls built with Tradical Hempcrete weigh just 50 tonnes, compared to 330 tonnes with standard concrete.
A crane was not required on site, which also saved on costs. Tradical Hempcrete was applied by mechanical spraying to the required thickness as worked progressed, and floor by floor.
Les Loges en Josas (Yvelines, France) – Grouped housing
With this project, DLA architects demonstrated the perfect marriage of timber, hemp and lime. The entire structure was shop-fabricated. It was lightweight, making it easier to lift, transport and assemble on site. Hempcrete was continuously sprayed on the walls and the roof. This optimised the ‘blanketing’, providing all-around self-insulation—including where the insulating wall and insulating roof joined.
