The JUBHome BASE load-bearing thermal insulation system for foundation slabs consists of a thermal insulation tub, thermal insulation of the perimeter and the reinforced concrete slab that is poured directly into the thermal insulation tub without any additional bracing. The JUBHome BASE system includes lower and upper layer floor elements as well as edge and corner elements. The latter serve as bracing during concrete pouring. All thermal insulating materials are in accordance with the SIST EN 13163:2013 standard.

JUBHome BASE assembly
All the elements are fixed either by a grooved or buttoned fit and there is no extra need of gluing. The thermal insulated tub is prepared and cut to size at the factory in accordance to the project plans and everything fits together like “lego” with the supplied assembly plans – fast and simple without problems.

JUBHome BASE for a variety of construction systems
-
JUBHome WALL
This is a system for the construction of walls out of thermallyinsulating ICF elements made of EPS (ICF – insulated concrete form). The edge elements of the thermal insulation of the JUBHome BASE foundation slab fit directly, without any thermal bridges, into the facade wall which is made of JUBHome WALL wall elements. The ground waterproofing consists of welded bitumen sheets, whereas the vertical waterproofing of the plinth is located directly beneath the render finish.
- MASONRY SUPERSTRUCTURES
The exterior plane of the masonry wall is aligned with the face of the JUBHome BASE raft foundation, whereas the thickness of the linear edge element depends on the design thickness of the façade’s thermal insulation. Waterproofing and ground insulation is implemented in the same way as in the case of a JUBHome WALL superstructure.
- TIMBER FRAME CONSTRUCTION ACCORDING TO A LOW-ENERGY STANDARD
The JUBhome BASE edge elements are geometrically adjusted to the vertical plane of the plinth waterproofing, thus providing a continuous waterproofing barrier when joined to the ground waterproofing layer. In order to ensure less severe waterproofing transitions, the top surface of the edge elements has a lateral. The space between the vertical plinth waterproofing and the facade plane is filled with EUROTHERM EPS F STRONG S0 boards. Vertical waterproofing is either self adhesive or else consists of bituminous waterproofing which is welded onto a base layer of reinforced JUBIZOL adhesive mortar.
- TIMBER FRAME CONSTRUCTION ACCORDING TO A PASSIVE ENERGY STANDARD
The load-bearing structure of the timber frame wall is shifted a certain distance outwards with respect to the vertical edge of the raft foundation. In this case, too, the top surface of the JUBHome BASE edge elements has a lateral slope in order to ensure continuity of the waterproofing and the thermal insulation.
Penetrations
When designing penetrations through the building exterior we have to ensure proper airtightness, waterproofing and thermal insulation. With a soft thermal insulation layer between the duct and the reinforced concrete slab, a potential horizontal shift in case of a very high horizontal load (eg. big earthquake) is possible.

Ground insulation around the perimeter of buildings
In the case of foundations whose bottom edges are located above the expected frost depth, the soil around the perimeters of the thermally insulated foundation slabs has to be thermally insulated. In this way, the occurrence of ice lenses beneath the perimeter can be avoided, including any damage to the waterproofing and the leaching of fine soil particles during freezing / thawing periods. This protection is provided by means of simply-supported EUROTHERM EPS F Strong S0 thermal insulation boards. The latter’s width and thickness depend on the annual average external air temperature at the site.
