XPS Insulation (Extruded Polystyrene): "XPS" commonly refers to extruded polystyrene insulation. This type of insulation is known for its closed-cell structure, providing good thermal resistance and moisture resistance. It is often used in various construction applications, such as insulating walls, roofs, and foundations.
B1 Fire Rating: The "B1" component might refer to a fire rating. In some fire classification systems, materials are rated based on their fire resistance, and "B1" could indicate a certain level of fire resistance. For example, in the European fire classification system (Euroclass), B1 represents a material with limited combustibility.
"ISO" in the context of polyisocyanurate insulation typically refers to the insulation material's type or category rather than an acronym. Polyisocyanurate is a type of rigid foam insulation known for its high thermal resistance (R-value) and effectiveness in providing thermal insulation.
A traditional roofing material of the Pacific Islands and Australasia, which is made from dried tropical grasses which are woven together and then bunched. Cogan Grass thatch is particularly dense so covers well and comes in rolls making it a simple and economical solution for circular roofs.
