A guide to specifying Terra Lana Insulation
Terra Lana insulation is formulated in such a way that each product can often be used in more than one location ie the R3.6 140mm wall product can be used in the ceiling. This guide is to help you better understand the product formulation and to assist you as the designer/specifier to ensure the best thermal performance of the building.
Terra Lana insulation is made from wool and polyester that both have a fibre diameter of around 30-35 microns. Fibreglass is around 6 microns and can achieve more small air pockets between the fibres and subsequently a higher theoretical thermal rating (R-Value). All insulation products are tested in bone dry laboratories at elevated temperatures. Keeping in mind these are theoretical tests, so once moisture in the building, durability of product and installation quality are considered, Terra Lana often becomes the product of choice.
