SIP’s is lightweight building material and there are more ways how to build foundation. The most commonly used method in our latitudes is the concrete foundation slab. Already during its construction it saves material because it will not need to handle such a load as in case of heavy masonry buildings.
Another way is to build foundation on lightweight concrete piles. Specially treated spreading timbers are placed on prepared piles to form a supporting structure. Subsequently, SE SIP 210mm panels are placed on the supportingstructure made to form a base slab. An alternative and unique solution is based on earth bolts. Making the base slab on the earth bolts under the family house takes 2-3 days and does not devastate the soil. The supporting structure for the bolts is made of timber sand the SE SIP 210mm panels are placed on the structure. The unique application of the SIP’s building system occurs also in the construction of houseboats. Panels are installed on the pontoon where they quickly and effectively create the foundation. It is used for making the outer walls and inner partitions


A waterproofing layer is applied to the finished base slab. After application, the sleepers made of specially treated timber are laid under all the outer walls and the inner partitions. The inserted KVH element is placed on the base sleeper and will be used to mount the panels. Construction of the outer walls starts from the corner of the building. When it is finished, the inner partitions are built. Finally, KVH wood elements are placed in top of the mounting grooves to reinforce the panels with each other. The panels may include a pre-assembled tunnel for wiring. All panels are labelled and made-to-measure according to the project documentation and so the construction of the panels is very simple, fast and accurate.


Between outer walls and inner partitions we make a ceiling structure to build a floor. We have several solutions to build the ceiling structure. The ceiling can consist of KVH, BSH timbers, wood glued I-beams, SIP panels or CLT. The kind of the materials to be used will depend on the designer's static assessment. We begin to build the outer walls and inner partitions of the second above-ground floor on such a constructed floor. SIP’s is the ideal solution to make staircases. According to the project documentation, the entire staircase system is made of the panels in a very simple way.


The SIP panels are an effective solution to make attics, flat or cantilever roofs. By laying the panels on the made-up structure of the outer walls or inner partitions, we create a thermally insulated roof structure without need to do thermal insulation work. The joints are straight and precise, so plasterboard or Fermacell boards are applied directly to the panels from the inside and battening and roofing, or waterproofing for flat roofs, from outside.
