Wood fibre replacing plastic and mineral wool in insulation
New wood fibre-based insulation materials and sprayable insulation foams will replace products made of non-renewable or poorly recyclable raw materials. These mass producible materials lower energy consumption at the production stage, and reduce the products' carbon footprint.
As part of the WoTIM project (Wood-based Thermal Insulation Materials), VTT Technical Research Centre of Finland is developing wood fibre-based insulation materials and sprayable insulation foams with enhanced product features. The WoTIM project involves the development of foam technique-based production methods in order to create high-quality wood-based thermal insulation panels and in-situ spray-on insulation materials.
The project aims to raise the overall performance of wood-based insulation to the same level as that of polyurethane insulation. The insulation properties of cellulosic materials can be improved by using foam-like structures to create closed-like air pockets in the material.
