Product description
The Iso3 stud is a rectangular, load bearing, wooden stud isolated with polyurethane foam. It consists of 47 mm x 95,5 mm wood, 47 x
67 mm polyurethane foam and 47 x 37,5 mm wood, and can be used in load bearing constructions in climate class 1 and 2 according
to NS 3470-1. Iso3 may also be used as transom or sill. The product is moulded by adding liquid polyurethane between two precut
pieces of construction timber. The polyurethane expands to a highly isolating foam. The production of Iso3 is yet not started, thus the
figures concerning energy use in production is based on estimates done by Moelven Iso3 (manufacturer)
Origin of round timber
95% of round timbers used in the production of Iso3 studs are certified in accordance with PEFC's standard

Waste treatment of final product
Products containing polyurethane must be treated with special care during handling, mounting and demolition. When
heated to 150°-200°C, isocyanates are released, which can cause allergies and asthma.
Final product must be treated as 100% residual waste and will, according to present technology and pratice, be
incinerated in authorized plants with sufficient flue gas cleaning systems. Landfilling of organic wastes is prohibited
after january 2009.
Energy recovery of after end of product life belongs to the system utilizing the energy. Only feed stock energy is
included in this analysis.
