PIR boards and PUR spray foam are polyurethane-based insulation products, but they differ in formulation, form and installation. PIR is commonly supplied as factory-made rigid boards. Spray-applied PUR is available in both open-cell and closed-cell versions, with different thermal and moisture properties. Board thickness is set during manufacture; spray thickness and workmanship must be [...]

Which sandwich panel core should you choose?Choose PIR primarily when you need high thermal performance with a thin, lightweight building envelope. Mineral wool is a natural option for higher fire-safety and acoustic requirements. EPS can be an economical solution for garages, warehouses and simpler buildings, provided its properties satisfy the design. The core name [...]

How much trapezoidal steel sheeting does a roof need?To calculate the quantity of trapezoidal steel sheets for a roof, you need the length and width of the roof slope and the chosen sheet’s effective cover width. Divide the length of the eaves by the cover width and round the result up to the next [...]

Thermal conductivity, temperature and summer comfort A house can overheat in summer even when its roof is insulated. The cause is not simply that mineral wool stops working in warm weather. Insulation slows heat transfer, but indoor temperatures also depend on sunlight through windows, shading, ventilation, internal heat gains and the complete roof construction. [...]
