Exclusion of moisture and heat-related problems due to iQ-Therm

When iQ-Therm insulation is installed, almost all the heating energy remains inside the closed living space and only a small quantity is lost through the walls. This leads to significant heating cost savings. Thanks to the combination of various physical properties, the use of iQ-Therm rules out moisture and thermal problems from the outset.

Tip 1: Surface decoration

The final surface design must be finished with breathable and open-capillary coating substances and systems. This also includes mineral-bound paint coats such as iQ-Paint, iQ-Paint ST and the Historic Lime Paint System (Color CL Historic) and Mineral Paint OH. Diffusion-inhibiting wall coating substances like wallpaper or latex paints are counter-productive to the function of the iQ-Therm system. They reduce the moisture balance between iQ-Therm and the inside. This causes a risk of moisture accumulation within or on the walls. Long-term subsequent damage cannot be ruled out.

Tip 2: Furniture

Furniture should not have direct contact to the wall to guarantee convection between the wall and the furniture. 1.5 to 2 cm (thickness of the carpet strip) as a distance is usually adequate.

Tip 3: Application of loads

Insulating material screw dowels, e.g. all-purpose dowels 50, should be used to hold medium loads like pictures, smaller wall lights etc. Short nails, length up to 2.5 cm, for holding smaller loads, are not a problem. For precise attachment of larger loads without thermal bridges (e.g. top kitchen cabinets, stair railings etc.), it is possible to work with cuttable, assembly cylinders made of PU hard foam.

Tip 4: Venting behaviour

The iQ-Therm system is based on the fact that moisture absorbed between the inside and outside during climate changes or during moisture control when the humidity is higher can also be discharged again. This, therefore, requires a corresponding ventilation behaviour.

  • Kitchen/bathroom: Lots of moisture can be created in these rooms in a short period of time e.g. during showering, bathing, cooking and also when wiping tiled floors. Vent these ‘moisture peaks’ directly. Open a window to allow intensive airing during or after cooking or after showering. If these rooms do not have windows, the necessary ventilation system can carry out this task.
  • Living space: Air based on instinct here. If the air quality is poor (“it smells”), we recommend opening windows for a short period.
  • If there are lots of plants or other sources of moisture in the living room (aquarium, indoor springs etc.), you should check the humidity regularly e.g. with a hydrometer (the values usually lie below 60% humidity).
  • Bedrooms: If you sleep with the window tilted, moist ventilating air can escape immediately. If the window remains closed at night, you should open the window wide and air the room (shock ventilation). In winter this only needs 5 to 10 minutes, in spring and autumn airing may take longer. You can use a hygrometer to establish whether the ‘relative humidity’ is lower than 60%. If this room value is exceeded, you should air for longer or more frequently (e.g. also in the evening).
