What is a SIP Panel?
SIP panel - a new building material, which is used in the construction of frame houses and hozpostroek. SIP - a layer cake, consisting of insulation (polyurethane foam), on both sides, "wrapped" OSB sheets (oriented strand board). The layers are held together by means of polyurethane adhesive and under strong pressure 18 tons.
Houses built from SIP panels are called in Russia "Canadian", because that's what the engineers in Canada have invented this method Construction, however, despite the harsh climate of Canada, the technology of construction of houses made of SIP panels still hated in Russia.
By the way, SIP stands for structural insulated panels.
The main advantages of SIP-panels:
- Good insulation. Total thickness of the panels 17 cm by 150 cm are heat brickwork;
- Excellent insulation;
- Lightweight panel (20 kg per 1 sq.m.)
- Quick construction deadlines: for the week really build a house of 50 sq.m.
The disadvantages of SIP-panels:
- combustibility
- Polluting material (OSB release formaldehyde)
How to control the builders, erecting House of SIP panels?
1. The builders want to save and buy SIP panels from unscrupulous suppliers. When purchasing CIP panels check the adhesive layer. Sometimes, in the manufacture of an adhesive layer applied to the surface unevenly and insulation strips.
Subtotal: SIR layer easily separates from the heater under the action of some force.
2. The second problem with the SIP-panels - the use of low-quality insulation that burns and releases harmful substances.
The result: a house of SIP panels burn for 10-15 minutes.
