General information

Ca. 20 % of the total heat loss of a single family house can occur by not insulated cellar walls. In order to reduce energy consumption, achieve pleasant indoor climate and prevent surface condensation, these rooms must be insulated. Thermal insulation of unheated areas of a building in contact with the ground is also beneficial. Thus, in the event of future conversion, comfort and energy efficiency can be achieved without requiring additional thermal insulation work.

RAVATHERM™ XPS 300 SL is an indispensable accessory for underground thermal insulation:

  • closed-cell structure,
  • excellent thermal insulation capability,
  • water-resistance
  • high compressive strength

Other information

From building physics point of view, the insulation placed on the external side of the building envelope is the best solution to prevent risk of condensation at the internal surface or within the structure.
The efficiency of the external cellar wall insulation should not be reduced by long-term exposure to moisture, ground-water and soil-pressure.
The excellent properties allow to install as the outermost layer of wall structure, even in direct contact with the soil. Apart of numerous advantages, the heat storing capacity of the structure will be preserved behind the outside thermal insulation.

INSULATION AND PROTECTION OF CELLAR WALLS

RAVATHERM XPS 300 SL is glued to waterproofing as its,

  • thermal protection
  • protection from mechanical damages

RAVATHERM XPS 300 SL can be applied not only in soil moisture but in ground water too.
RAVATHERM™ boards are not bio-degradable in the environment and does not present an environmental hazard in the water/soil compartment.

Technical

INSULATION AT GROUND MOISTURE

RAVATHERM XPS insulation boards are simply bonded with INSTA-STIK polyurethane solvent-free adhesive to the external face of the waterproofing membrane or the waterproof reinforced concrete cellar wall. To wall surface the adhesive should be bead-applied (min. 3 strips per board). The insulation boards are installed with tight joints and in brick pattern, either horizontal or vertical position on the cellar wall. RAVATHERM XPS boards must “stand” on a firm base area at the foot (for example foundation step), having a support base to avoid the sliding during compacting the backfill later.

INSULATION IN GROUND-WATER

RAVATHERM XPS boards can be used also when exposed to permanent pressure of ground-water. The entire surface of the insulation boards must be adhered with solvent free cold bitumen adhesive to the waterproofing membrane or watertight reinforced concrete wall in order to prevent water standing between the insulation layer and the membrane or concrete wall.
