A new concept for Uponor’s low thermal loss culvert, embedded in LECA, is being tested here for the first time.

Background

The entire area will be permeated by ecological sustainability and energy-efficient buildings. The neighbourhood will consist of a mix of buildings, including apartment buildings, terraced houses, semi-detached houses and detached houses. All houses will be classified as low-energy houses, i.e. they will be very well insulated, have a high air tightness, efficient ventilation and will recycle heat from the exhaust air in heat exchanger units. The neighbourhood is expected to be ready in 2017.

Solution

“During the first stage 22 terraced houses will be built, and each house will be fed using a new low thermal loss concept for culverts,” says Sami Kallio, product manager for culverts, comfort panels and sprinklers at Uponor. “Lillhamra is unique from Uponor's point of view since it is the first time our culvert will be embedded in LECA. The LECA will be encapsulated with a non-woven fabric and covered with a normal filler. “An independent consulting company has calculated the thermal losses with the Uponor culvert system embedded in LECA, and it demonstrates a very good insulating effect,” says Kallio.

Heating to the area will be distributed by the local energy company Mälarenergi. “This is a solution which means our culvert system meets Mälarenergi’s requirements regarding low thermal losses for an energy-efficient residential area,” says Kallio.

Result

Uponor’s culvert system was installed in this case by Peab Anläggning. “The culvert was convenient to lay, despite some intricacies with the couplings,” says Martin Landås, supervisor at Peab Anläggning. “The LECA worked well too. It was quicker to lay it compared to normal aggregate since it did not need to be processed before the culvert was embedded.”

Ulrika Eriksson, worker at Peab Anläggning, was part of the team who installed the low thermal loss culvert in Lillhamra. “It was the first time we worked with culverts but it worked out fine. We did the culvert training at Uponor Academy just before we started working a Lillhamra, and the training was really useful. The LECA was easy to work with. We tried spraying it in from the truck, but it was easier when it came in cartridges,” says Ulrika Eriksson.
