ANTLER HOUSES - WITH A PASSION FOR THE ENVIRONMENT
- We have always worked actively to reduce our impact on the environment and now we are taking another step in the right direction to minimise our carbon footprint," says our CEO Peter Gyllenberg.
- "In 2024, we at Jörnträhus have changed the construction method for our wall blocks, from traditional wooden frames and mineral wool insulation to lightweight beams from Masonite Beams and wood fibre insulation from Svenska Termoträ," Peter continues.
Another positive environmental aspect of changing the construction method for the wooden houses is that waste and spillage from the job of insulating the wall elements is reduced. The wood fibre insulation is injected in the form of loose wool and fills all the spaces efficiently without creating waste pieces as previous insulation methods could do.
"Our carbon footprint should be as small as possible."
THERE ARE OTHER IMPORTANT BENEFITS!
- "We now have the possibility to build up to 8 storeys in height, our previous and more traditional building system limited us to 2 storeys. This means a great opportunity to develop our products and be attractive suppliers on more types of projects, says our CEO Peter.
- Lightweight beams have been used in floor structures for several years, such as in the Birkarlen Nordic Swan Ecolabelling project, where we have successfully delivered 16 blocks of flats with a total of 188 apartments for the client Contractor. So we know that the quality, delivery reliability and customer support are good for these products," Peter continues.
THE TOWNHOUSE PROJECT
Jörnträhus is already working on its first real project where the lightweight beam system is used in both exterior walls and floors, this at Getberget in Skellefteå where the client is building 20 terraced house apartments in 2 buildings.
Each apartment is 98.5 m² and will be ready for occupancy in winter 25/26. The assembly of the blocks began in mid-November and is expected to last until the end of January.
"We would like to see more clients setting higher standards for sustainability."
- We see that the demands for sustainable products are increasing for housing construction in Sweden and we are really excited to be involved in more important Nordic Swan Ecolabelled housing projects," says Peter.
- In order to achieve more sustainable construction in Sweden, we would like to see more clients setting higher requirements in their procurements already now," concludes Peter.
FACTS
External wall with wood fibre insulation
Load-bearing external wall for buildings up to eight storeys. The loads are absorbed by Masonite's lightweight brick. The wall provides good construction economy, not least by minimising waste, and is also excellent from an energy point of view. The lightweight beam construction reduces thermal bridges and thus provides a well-insulated wall.
Construction from the inside out:
- Gypsum GF 15 mm.
- Plywood 15 mm.
- Rule 32 x 45 mm, landscape.
- Vapour barrier.
- Lightweight beam HI250 + wood fibre insulation lambda = 0.038 W/mK.
- External inorganic windscreen 9 mm.
OUR SUSTAINABILITY WORK
At Jörnträhus, we work actively to reduce our impact by, among other things...
- Build with environmentally friendly and locally sourced timber that sequesters carbon throughout the life of the product.
- Minimise waste in production.
- Improve the proportion of sorted waste.
- Recycle residual products.
- Buying wood products locally.
- Buying inputs from suppliers who share our environmental vision.
- Making transport more efficient with well-loaded vehicles.
- Increase the share of aggregated material from multiple suppliers to increase transport efficiency.
- Systematise local environmental work and improve the documentation of the environmental impact of our products.
