Interior insulation system/iQ-Therm 2.0

iQ-Therm 2.0

The new strip technology

iQ-Therm 2.0 is an update to the capillary-active interior insulation iQ-Therm that was first launched in 2009. In the iQ-Therm system, a high-performance insulating material is combined in the cross-section with a mineral mortar, which makes it possible to achieve a capillary absorbency in the system that eliminates the need for a vapour barrier.

In the previous iQ-Therm system, capillarity was achieved by perforating the panels at regular intervals and filling the holes with a special mortar. In the new iQ-Therm 2.0 system, this concept has evolved, with the point-shaped capillary-active areas being transformed into strips. The revamped system now also offers the option of using insulation thicknesses of more than 80 mm; iQ-Therm 2.0 is currently available in thicknesses of 30, 50, 80 and 120 mm.

Only a few simple tools are needed for application: a knife for cutting, a slurry brush or scraper for applying the adhesive mortar and thin plaster iQ M universal, and a notched trowel for applying iQ M universal as thin coat plaster or iQ Top as climate regulating plaster in the end.

Mode of action

Simple mode of action

combines heat insulation, capillarity and humidity regulation

There are different types of moisture transport in and through building components. To prevent damage, these must be intelligently managed – especially in the case of interior insulation.
The iQ-Therm 2.0 insulation strips are bonded to the wall and in the horizontal joints on site using a special, highly capillary-active adhesive mortar. The result is a composite material with a high insulating effect and simultaneous capillary activity, without the need for a vapour barrier.
If condensation forms in the system because the temperature falls below the dew point in winter, or if driving rain penetrates through the facade, with iQ-Therm the moisture is not trapped behind a film, but is instead channelled out of the wall cross-section via the mortar in the horizontal joints and back into the room air without causing damage.
Finally, the interior insulation is either filled or plastered over with a porous, mineral lightweight mortar, a so-called “climate control mortar”. This final layer acts as a sorption layer for the surface distribution of moisture, levels out the surface temperatures and serves as the installation layer for any subsequent surface finishing.

Application
1. Preliminary work
Remove old wall coverings, e.g. wallpaper. The substrate must be clean, dry, absorbent and stable.

2. Applying insulation partition strips
A so-called partition wall strip is laid on the floor and, if necessary, along the acoustical and mechanical decoupling as well as gap-free connection. In the connection to the ceiling, Kompriband 15/5-10, a pre-compressed tape sewn into PP foil for terminable decompression, must be used..

3. Applying adhesive mortar
The first capillary-active mortar bed joint is installed at the base of the partition strip using iQ M universal. Apply the material in a slurry with a brush or trowel to a thickness of approx. 1 mm. On the wall, iQ M universal is applied vertically over the entire surface with a suitable notched trowel to create an adhesive bed with a layer thickness of approx. 3 mm. The entire adhesive bed must be free of cavities.

4. iQ-Therm 2.0 - Applying the basic layer
Now, embed the first row of iQ-Therm 2.0 insulating strips in the mortar bed. Do not bond the joints of the insulating strips. The base layer of the iQ-Therm 2.0 strips should be laid out as horizontally as possible.

5. Installing the insulation in strips
The installation of iQ-Therm 2.0 is now continued layer by layer, whereby the bearing joints are made with iQ M universal set to slurry in 1 mm thickness. Cross joints between the strips must be avoided.

6. Applying climate-regulating plaster / filler
Once the wall surface is complete, apply the climateregulating plaster iQ Top or the thin-coat plaster and adhesive mortar iQ M universal in two layers with an embedded reinforcement fabric. This is needed in order to avoid cracks and to prevent the joint areas from becoming visible on the wall surface over time. Both products are humidity-regulating and noticeably improve the room climate.
