SIP panels

Nowadays, the construction of residential houses and holiday cottages are increasingly focused on efficiency, environmental friendliness and speed of erection of structures.An excellent material, and one of the leaders in terms of performance and installation are self-supporting insulated panels or SIP (Structural Insulated Panel) - Structural Insulated Panel (CTI).

Thanks to its modern production technology and competent combination of several building materials,they allow you to build a solid structure to build the walls and floors with high thermal insulation.

What is SIP-panel?

material is a structural insulated panel having the form of briquettes with the possibility to cut out part of it any form.The composition of the panel consists of two main components.This external protection made of OSB and internal filler in the form of polystyrene.In turn, the OSP coating is made from wood chips, compressed under high pressure, which perfectly protects the insulation, inside the SIP-panel.Expanded polystyrene is used in the manufacture of building construction has increased stiffness performance that enables high-strength panel.

Two sheets of OSB and polystyrene foam sheet are joined together by the method of bonding at the factory.It allows the production of the factories to create optimal conditions to perform bonding.High blood pressure during the gluing panel provides solidity and a long life without segregation.The plant may perform a standard sample plates and special plates of individual form for each project.

relative thickness most SIP panels and thickness of the protective sheet of OSB, they can vary according to the needs of the application site.The standard thickness of the panel varies from 60 to 224 mm, depending on the needs of the heat insulation and strength erected wall or ceiling.Typically, SIPs panels with maximum width is used for external walls and ceilings, where they will provide the highest thermal insulation performance and durability.

Mounting panel

All panels manufactured in the factory, once the process of installation is provided with the execution of the mounting slots on the edges.

panels are fastened to each other by the method of using timber with fixing screws that provides reliable and durable fastening.

All seams between the panels will have less heat-insulating properties, so in order to reduce the thermal conductivity of the foam used indicators.Foam perfectly fills the gap between SIP guaranteed eliminating cold seam.

Properties SIP panels

Thanks to the design of expanded polystyrene, the panel has a very low heat conductivity, which allows to build-thermoses premises.This property is self-supporting insulated panels for nearly 60 years has been successfully used in the United States and Canada, allowing you to produce isolated from the outside of the room temperature.Full insulation will significantly decrease the cost of heating or air-conditioning premises, making it more cost-effective.

first time confronted with the technology, it seems low strength of such a panel, because individually each of the components of the CIP has a low strength compared to brick or concrete.But in fact, shaped and molded SIP has high specifications, allowing to fully meet the needs of any house.The panel of multiple experiments showed no deformation or damage, when the lateral load of 2 tons and longitudinal loads up to 10 tons.Particularly important indicators of longitudinal strength, allowing to use the panel as the load-bearing walls for the construction of buildings of several floors.

Specifications SIP panels

• thermal conductivity of 0.039 W / (m * K);
• time independent burning no more than 4 seconds;
• is odorless, does not contain polluting substances;
• operating temperature range from -180 to +80 ° C;
• water absorption at full immersion in water no more than 3% by weight per hour.

Advantages and disadvantages

Among the advantages of SIPs should note the following superior performance:

• Soundproofing comparable to the brickwork of two meters thick;
• Houses built of SIP panels have third degree of fire resistance (fire duration of deterrence - 1 hour).The panels themselves are treated with flame retardant, self-extinguishing material that gives the property;
• has the highest ecological safety requirements;
• not have competition among construction materials on the insulation index.

Among the disadvantages are the following:

• higher flammability, than in brick houses;
• Lower load bearing capacity than the concrete frame;
