SIP - Structural Insulated Panel is a versatile, highly stable and ecological building system for construction of low-energy and passive buildings.

Structural rigidity of the panels allows designing and constructing almost any shape-diverse structure. Thus, the SIP’s building system can be used to build family and apartment houses, office buildings, manufacturing and industrial halls, schools, recreational buildings, cottages as well as garages.

As SIP’s is a lightweight building system, it is ideal as a superstructure and extension solution for existing buildings. SIP’s can also be used in combination with other building technology.

The building system is ideal as a roof structure solution with additional attic use and is ideal for flat roofs.


The building system is based on a sandwich panel. The panel consists of two OSB4 - oriented strand boards and an insulating core consisting of expanded flame retardant polystyreneEPS or PUR

The result is a self-supporting construction panel that is characterized by excellent thermal insulation properties and high structural rigidity.


The insulated SIP Spline jointing element is an important part of the building system that is used to interconnect the panels. It ensures there are no interruption of the insulating core and no excessive heat bridges.

The panels are manufactured in controlled factory conditions. The panels are cut and tailored to project documentation but they can also be delivered individually. The construction process is therefore very fast, accurate; no construction waste is generated and hence no unnecessary costs for the investor.

The buildings made of SIP's are highly durable, eco-friendly and economical.


The SIP’s building system can easily be completed with a wide range of finishing layers. Starting from classic plaster up to ventilated facades.

The material needed to complete fabric – as one package. Time is saved, supply organization and construction process are not unnecessarily interrupted due to subcontracting.

The panels are manufactured in standard timber sizes. The delivery of the construction system includes also certified KVH, BSH timber in strength classes C24 or GL24h dried to 15% and wooden glued I-beams. Their quantity and sizes depend on the structural assessment of the building.

Various joints, carpentry fittings, PUR foams, sealants and compression tapes are used for panel connection to seal joints.

All materials are a part of the individual delivery of the building system according to submitted offers and they need not be provided additionally.
