SIP - Structural Insulated Panels

Our building system is a new generation of timber structures. Unmatched construction speed, versatility, high strength and thermal and hydro insulation properties make the our system a highly efficient construction system for the construction of net zero energy and passive buildings.

The panel consists of two 15mm OSB TOP4 boards and an insulating core of expanded flame-retardant EPS polystyrene, NEOPOR graphite polystyrene or PIR.

The result of the manufacturing process is a construction sandwich panel characterized with excellent thermal insulation properties, low bulk density and high structural rigidity.

The panels are made in several thicknesses, so their use will cover a wide range of needs. They can be used for floors, perimeter walls, partition walls and roofs.

The construction system using SE-SIP panels is classified in the category of timber buildings, but thanks to its physical and thermal insulation properties, it significantly outperforms conventional timber buildings.

In addition to panels, the SIP construction system makes use of certified KVH and BSH structural timber in strength class C24 or GL24h, wooden bonded I-joists or CLT panels. Their quantity and dimension depend on individual static assessments of buildings.

For panel joints, various connecting elements, carpentry fittings, PUR foams, sealants and compression tapes are used to seal the joints. All materials are part of individual supplies of the construction system according to the demand submitted and there is no need to provide them retrospectively.

Construction Foundation

SIP panels are lightweight, so foundations can be simpler. The most common is a concrete slab, which requires less material than brick or concrete buildings.

Foundations can also be made from panels or screw piles. A screw pile base for a detached house takes 2–3 days, avoids land damage, and supports wooden or steel beams carrying SIP 210 mm panels.

SIP construction is also used for houseboats, where panels on pontoons create fast, efficient foundations.

Construction of Perimetter Walls and Interior Partition Walls

Construction of the perimeter walls begins from the corner of the building and continues around the perimeter. After their completion follows the installation of internal partition walls. Finally, wooden KVH elements are inserted in the mounting grooves from the top to support the panels with each other. The panels may contain a pre-prepared tunnel for wiring. All panels are marked and custom-made according to the project documentation, so the installation of the panels is very simple, fast and precise.

A layer of waterproofing is applied to the fabricated foundation plate. After its application, the foundation springs are anchored to the foundation plate and form the base for the construction system. An embedded KVH element is fitted on the foundation spring to install the panels.

Floor Construction

Between the perimeter walls and the interior partition walls, we make a ceiling structure for the construction of the floor. To create a ceiling structure, we have several solutions. The ceiling can consist of KVH, BSH ceiling elements, glued timber I-beams, SE-SIP panels or CLT. The suitability of the materials used depends on the static assessment of the project architect and the requirements of customers. On the floor constructed in this way, we begin to build perimeter walls and internal partition walls of the second floor.

Roof Construction

SIP panels are an effective solution for the construction of sloping roofs with a residential attic. The SIP construction system essentially creates both a structural and an insulating element of the roof. The attic is therefore directly insulated with SIP panels and no additional application of insulation materials is required. The joints are straight and precise, so the interior has final base for the installation of gypsum or fibrous gypsum boards, which are applied directly to the panel

SIP panel is also an ideal solution for flat roofs. As with both sloping and flat roofs, the panel is a structural as well as an insulating element of the roof. Its installation and application are very fast and saves a lot of additional work. From the inside, it is possible to install gypsum or fibrous gypsum boards directly to the panel. From the outside, EPS perimeter drains for water drainage and final waterproofing are applied.

Wide Variability of Final Finishes

The SE-SIP construction system can be easily completed with a wide range of finishes from classic plaster to vented facades.
