High Performing Insulated Green Material OSB Facing EPS Structural Insulated Panel SIPs Roof Wall Sandwich Panel
Introduction of SIPs
Structural Insulated Panels (SIPs) are an advanced method of construction, exploiting composite panel techniques, and delivering excellent structural and thermal characteristics in one system. Structural Insulated Panels (SIPs) are a modern construction system offering excellent insulation values and super-fast build speeds
The panels consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board (OSB). SIPs are manufactured under factory-controlled conditions and can be fabricated to fit nearly any building design. The result is a lightweight building system that is extremely strong, energy-efficient and is quick to erect, and free from the complications of thermal bridging.
|Fire resistance||CE Class B1|
|Dimensional stability (70 ℃± 2 ℃, 48h)||≤1.0%|
|Volumetric water absorption||1.4%|
|Wide operating temperature range||-250 to 150 C degrees|
SIPs are engineered, load-carrying, timber-based panel products that can be used in walls and roofs of residential and light commercial buildings. These lightweight panels combine the structural and thermal envelope of the building; they are manufactured offsite in a factory and shipped to the construction site offering advantages to the build programme. This panelised form of construction allows SIPs to be assembled to form highly airtight, energy-efficient building envelopes.
SIPs (structural insulated panels) are pre-insulated, storey-height panels that can form part of a building or whole buildings.
The panels are made of either cement particle board (CPB) or, more commonly for self build, engineered wood-based sheets known as oriented strand boards (OSB). Two sheets of this are sandwiched together with a rigid insulation (such as polyurethane).
SIPs have thermal and sound-insulation properties that comply with, or often significantly exceed, current Building Regulations and some incorporate a vapour-controlling membrane.
Why Choose SIPs?
1.SIPs are manufactured to bespoke measurements and designs, reducing material waste
2.Offsite manufacture gives cost and supply predictability
3.High insulation performance results in lower building energy consumption, therefore, reducing CO2 emissions
4.SIPs are suitable as roofing elements that maximise space for room-in-the-roof
5.Quick installation on site allows for programme improvements
What are the advantages of building a whole house with SIPs?
Although it might look as though it is an expensive way to build, there are savings.
As the house can go up in a matter of days – construction is made simpler as window and door openings can be pre-cut, and the inside is battened to accept plasterboard while leaving gaps for the electrics – fewer tradespeople are needed and for a much shorter time than with a conventional build.
A four-bedroom house, for instance, can be erected and weatherproof in a minimum of five days. There is also less waste (you only get the materials you need) and mess to clear and dispose of.
The lightweight nature of the panels can lead to a reduction in foundation loadings, giving the structural engineer flexibility of design, and often meaning a reduction in groundwork costs.
