A Cracking in hardboard is often caused by uneven substrates or thermal stress. It's recommended to align the substrate with a level before installation, fill joints with elastic sealant, and leave a 5mm expansion joint to relieve thermal expansion and contraction stress. This can effectively prevent cracking.

A Thermal insulation performance degradation is often caused by moisture or compression deformation. This product has a water repellency of ≥98%. If it becomes damp, wipe it dry immediately and ventilate the area. During installation, maintain a 3-5cm air gap to avoid excessive compression, which increases fiber density and affects thermal conductivity.

A Air leakage is often caused by insufficient overlap width or inadequate sealing. We recommend using the "upper-press-down" overlap method, with an overlap width of ≥10cm. Apply three strips of aluminum foil tape along the longitudinal direction of the joint and secure with cable ties to create a triple seal.

A Condensation is often caused by excessive temperature fluctuations or a damaged breathable membrane. This product has a built-in breathable microporous structure. Ensure the breathable membrane faces the windward side during installation. If condensation occurs, check that the insulation thickness is ≥ 20mm and install drainage channels to drain the condensed water.

A Centrifugal glass wool uses highly elastic fibers, so slight compression does not affect performance. If deformation exceeds 15% of its original thickness, use a heat gun at a low temperature (≤ 60°C) to restore elasticity. Severe deformation requires contacting after-sales service for replacement. For transportation, use upright packaging to avoid stacking flat items.
