What are SIP panels?
The word SIP stands for a structural insulating panel. This building material is a construction of three layers: two plates of OSB and a layer of expanded polystyrene in the middle. With the use of polyurethane adhesive, under a pressure of 18 tons, these components are interconnected. Panels are produced in two types: wall and floor.
We characterize the main components of
- Oriented chipboard( OSB) - 97% of the material is wood chips, folded in several layers and glued together with various resins. In wood chips all useful properties of wood are preserved, but there are no various defects: knots, change of fiber direction. To impart elasticity and strength to the board, the chips are placed in different directions during the gluing process, they are placed longitudinally in the outer layers, crosswise in the inner layers. Due to such a multidirectional orientation, as well as special treatment ensuring water resistance, resistance to mold, rotting, the plate becomes an ideal building material.
- Styrofoam - is located in the middle of the CIP panel, 98% consists of air, and the remaining 2% - styrene. Polyfoam is environmentally friendly and non-toxic material, has a long service life, low weight, as well as high thermal insulation characteristics. Due to the above properties, the material is the most demanded insulation in construction work.
Characteristics of SIP panels
This building material is used for erection of frame-panel buildings, country houses, verandas or extensions.
The main properties of panels:
- size - the maximum height - 350 cm, width - from 63 to 150 cm, thickness - 5-23 cm, it all depends on what the panel is designed for, indoor, outdoor or for overlapping;
- weight - is light in weight. For example, a panel measuring 250x125x18 cm has a weight of 50 kg. The total weight of the SIP panels for the erection of a house of 150sq.m.will be 15 tons. The weight of the brick, which will be needed to build a house of the same area - 60 tons. Due to the small weight of the plates, it is possible to save considerably when building the foundation and when transporting the purchased material;
- increased resistance to load - the material has a three-layer structure, so it can perfectly withstand a longitudinal load( 10 tons per 1 sq. M.), As well as transverse( more than 2 tons per 1 sq. M.).With vertical bending, one of the plates is compressed, and the other at this time is stretched, which provides the structure with high resistance to bending. These characteristics allow the design to withstand strong gusts of wind, snow and rainstorms well. The maximum permissible load that the floor can withstand is 150 kg per 1 sq. M;
- high thermal insulation properties - this causes low thermal conductivity and a three-layer panel structure. SIP panel with a thickness of 12 cm has the same properties as brickwork with a thickness of 2 meters or reinforced concrete with a thickness of 4 meters;
- high resistance to fire - the plates are treated with a special substance - fire retardant, which leads to self-extinguishing of the fire on the surface. The fire resistance of the material is 7 times higher than that of wood.
It can be concluded that the SIP panels are ideal as a building material for prefabricated houses.
Positive properties of
panels There are certain qualities of this material, which determine their effectiveness and relevance in comparison with other building materials:
- increased preservation of building heat in 1,5-2 times;
- accelerated installation - the house "turnkey" will be ready in 3 months from the beginning of construction work;
- strengthening and building strength of the building;
- CIP panels are not susceptible to deformation during operation;
- it is possible to build a lightweight frame, becausesome load will take over the panel itself;
- eco-material - the panel is 97% wood chips, and impregnations, waxes, fillers and expanded polystyrene are completely harmless to health;
- panels are flat, thanks to this, you can immediately perform the decoration of the room, which will significantly save time and money, becauseit will not be necessary to perform the filler;
- CIP panels do not require thermal insulation;
- a small thickness of the plate makes it possible to increase the usable area by almost 30%.
We see that the construction of a house with the use of CIP technology meets all the characteristics of thermal protection, durability and reliability.
The cost of SIP panels
To ensure that the final product was really good, you need to pick up good material and properly perform all the technological processes. Implemented by all standards, the CIP panel is expensive.
Of course, you can save and buy panels made by hand in private workshops. But as a result, you can get a badly glued surface with an unevenly applied adhesive coating and a layer of low-grade polystyrene, for example, PSB-15.
As a result, the building will be built with disabilities, which will reduce all the characteristics of the material used, and in time may even be dangerous for residents of such "economical" and "artisanal" houses.
Therefore it is better not to save, but to buy guaranteed quality SIP panels from the factory manufacturer in order to have a reliable, warm and modern house.
