Structural Insulated Panel or SIP is the new buzz-word in building construction industry as 21st century "green" building material. SIPs can be used in the construction of exterior walls, floors and roofs of residential and commercial buildings offering advantages of low cost and energy conservation over traditional wooden frame construction. SIP addresses two major concerns while building "green" home - energy efficiency and diminishing natural resources.
The general characteristics of all SIPs are two exterior skins sandwiching a rigid foam plastic core made up of low cost expanded polystyrene material. The skins most generally used are oriented strand boards (OSB), plywood or gypsum board. The resulting sandwich panel is exceptionally solid, cost effective and energy conserving which can be used as load bearing walls, partitions and roof insulation.
When used as a load-bearing wall or roof insulation, the two skins act as lean columns constantly supported by the rigid core to resist buckling and compression. When bending is applied to the panel due to a live or a wind load, the skins take most of the compressive and tensile forces and the core offers resistance to shear. Skins and rigid core acts internally to provide exceptional strength to the structure.
The most important characteristic of Structural Insulated Panel which has led to rapid growth in its demand is excellent energy efficiency and improved thermal performance. Today, one of the major challenges for any home owner is to control increasing energy costs. SIPs are practically airtight panels due to the nature of material used and fabrication process. This results in less cooling during winters and less hitting in summer! Hence buildings made with SIP panels require less expensive cooling and heating systems than a normal building saving more energy and costs. A building constructed with SIPs takes less time than the one with wooden frame. This saves you labor and wastage at the job-site. Overall building a home with SIPs can save you energy, costs, time and labor too!
Design of Structural Insulated Panel requires good amount of structural drafting & design services.
