What is the best material for roof insulation?
① Expanded polystyrene board, with thermal conductivity of 0.038-0.04 1, is cheap and its strength is slightly poor;
(2) Extruded polystyrene board, with thermal conductivity of 0.028-0.03, high strength, high moisture resistance and expensive price, needs surface treatment during construction;
③ Rock wool board, with thermal conductivity of 0.04 1-0.045, is fire-proof, flame-retardant, hygroscopic and poor in heat preservation;
(4) Rubber powder polystyrene particle thermal insulation slurry, with thermal conductivity of 0.057-0.06, good flame retardancy, secondary recycling and high construction requirements;
⑤ Polyurethane foam material, with thermal conductivity of 0.025-0.028, good waterproof, high strength and expensive price;
⑥ Perlite slurry has thermal conductivity of 0.07-0.09, good fire resistance, poor heat insulation effect at high temperature and high water absorption.
How much is the insulation material roof insulation board?
How much is the roof insulation board per square meter? Its price generally ranges from 65,438+000-800 yuan according to the material model, and the performance of products with different prices is also different. For example, the rubber roof overhead insulation board with fire prevention function has a thermal conductivity of 0.034, and the price is around 760 yuan. There is also an overhead cement insulation board with ordinary heat insulation function, and the price is only about 100 yuan.
