How Accepted Panel Accelerates Construction

The insulated panel is a prefabricated building panel used on the floor, , ceiling of the building.  isolated panels for designated building construction to ensure energy efficiency, easy and fast installation and reduced operating costs. The structurally insulated panel is a composite building, consisting of an insulating layer core sandwiched between two metal chairs.

SIP features

SIP is generally made of Strand Strand Oriental (OSB) panels flanked around a foam core made of expanded polystyrene (EPS), extruded polystyrene (XPS) or rigid polyurethane foam. Other materials such as plywood, pressured plywood for foundation walls under floor, steel, aluminum, cement boards such as Hardie Backer, and even exotic materials such as stainless steel, fiber-reinforced plastic, and magnesium oxide can also be used instead. From OSB. SIP provides continuous air and steam barriers as well as increased R-Value compared to traditional construction. When labor costs, waste materials and energy efficiency are considered SIP comparable harga plywood  to conventional building methods.


The idea of ??the Structural Insulated Panel (SIP) introduced the Forest Product Laboratory in Madison, Wisconsin in 1935. The laboratory developed a prototype panel consisting of members of framing, plywood and sheath board, and insulation. This initial panel was used to build test houses and tested after 30 years to reveal that the panels retained their initial strength. In 1952 Alden B. Dow created the first mass-produced SIP foam in the 1960s.

How to use SIP

SIP is designed to withstand axial load, shear load and edge load. This can be used for flooring, walls, roofs etc … for buildings. They have the ability to withstand two-sided bending and lateral shear; So, they are very suitable for use as roof and floor. The most commonly used connection panel connections are the Surface spline and Spline Block. The Spline Joint Connection surface consists of an OSB or plywood strip inserted into the slot in the foam. Spline blocks are thin and narrow SIP assemblies that are inserted into a niche in the foam along the edge of the panel. This connection produces a continuous foam core in the panel. This helps eliminate air filtration in the joints.

Another shared connection is the Mechanical cam lock, making a tight connection between panels. In all types of connections, the seams along the sheath should be covered with a continuous line of tape panels. It can not happen on the edge of the panel, so the panel can be hidden to access the wooden header. Opening in SIPs that accept other closing elements must be sealed correctly.
