SIP panels (structural insulated panels) are the best insulated wall panels and insulated roof panels for commercial and residential use. They are an environmentally friendly, dimensionaly stable, modular building products. With high insulation value, excellent water resistance, ligh weight, and low cost, our versatile insulated wall and roof panels are ideal for use in all types of building plans. If you want to reduce time on installation labou, save money on energy costs and recycle the planet's resources, we are the SIP panels manufactural for you. The design of SIP panel is such that it reduces the amount of air leaking into and out of the house, thus reducing your energy bills. SIP panels emit less greenhouse gasses than traditional stick frame construction. It is suitable for various climates, including long, cold, wet winters. Strucrure of SIP panels.We have two types of SiP panels. 1.OSB+XPS+OSB 2.wood+MDF+XPS+OSB. Compared to EPS core, our SIP panels are made with XPS foam core, which has higher compressive strength, lower water absorption, lower thermal conductivity and longer service life etc. The normal size of our SIP panels: Length:2400mm, width: 600mm, thickness: 30-140mm (optional) Packages: pack in cartons. MOQ: 1*40’HQ Thermal conductivity: Less than 0.030W/(m.k) Compressive strength: more than 250Kpa Tensile strength: more than 300Kpa Bond strength: more than 200Kpa
