Construction

The Foundation

Lightness of SIP constructions allow multiple foundation types. We mainly use strip concrete foundation with reinforced concrete slab.

An alternative solution is building a foundation of SIP panels on screw piles. We mostly use this method in cases when deficient soil quality significantly increases the cost of a concrete foundation.

Exterior and Bearing Walls

Before assembling the walls the foundation is covered with waterproof material and foundation sleeper beams are attached to the foundation with metal anchor bolts.

Joining of the panels

To avoid thermal bridges we use no-carcass technology (splines). We use wooden timber beams to secure the ends of panels, for apertures and corner connections as well as enforcement of load points.

Interflooring

We use SIP construction for interflooring. The interflooring panels are connected to the bearing beams that come up against the bearing walls. The cross section pitch and size of the beams are calculated depending on the width of span.

The Roof

If the project includes an insulated roof - SIP panels are an ideal choice. You can use a system with built-in beams as well as place the panels on for example, constructions made for farming (stalls), if a large area needs to be covered.

Finish

For interior trim we use plasterboard that is attached directly to the panel surface (OSB) without profile constructions.

The exterior finish may vary: siding, wooden boards, plaster on rock wool or EPS, external decorative tiles, decorative cement plates etc. The preferable thickness of a finished facade with insulated plaster is 172 mm. The thickness of insulation depends on the energy efficiency requirements of the building. When facade finish materials without insulation are used we suggest using a 222 mm panel.

Communications

To avoid thermal bridges, we do not install communications (water supply and power supply) inside the panels. We place communications in the channels made inside the plasterboards. If the communication diameter is too large, we make additional profile constructions.

Ventilation

SIP houses are highly hermetic and require installation of a ventilation system. Both types of available ventilation systems can be used an active (recuperation) or a passive (natural) one. The choice depends on the energy efficiency requirements and purpose of a particular project.
