SLENTEX® non-combustible insulation

SLENTEX® is a silica aerogel based on high-performance thermal insulation material.

SLENTEX® allows for a high degree of design freedom, and enables very slim construction systems for insulation in both new build and renovation. Whether historically protected facades, building elements, or uneven brickwork, SLENTEX® can be applied flexibly wherever other insulation materials reach their limits.

Features and benefits

  • SLENTEX® is non-combustible (class A2-s1, d0 in accordance with DIN EN 13501-1)
  • Entirely mineral-based product
  • Low lambda value of λD 19 mW/m . K for 25–50 % slimmer thermal insulation systems
  • Open to diffusion (μ ~ 5)
  • Amenable to flexible processing – suitable for specialized insulation requirements
  • SLENTEX® is certified (ETA-18/0011)

Ventilated facade

Using SLENTEX® as an insulation layer in a ventilated facade allows the anchor dimensions to be reduced, thus reducing the requirements for static performance and thermal decoupling of the anchors as well as the total system thickness. This is an additional benefit besides the general space-saving effect of high-performance insulation. An example construction with SLENTEX® insulation is schematically illustrated below.

Roller shutter case

SLENTEX® placed behind a roller shutter box or sunblind system allows the box front to be aligned with the facade surface without creating a thermal bridge; see the illustration on the left.

Window reveal
In the case of retrofitting internal insulation, the continuous thermal bridge in the area of the window frame and the reveal is reinforced by the now cooler existing wall. If there is no effective insulation due to the limited space available around the window, the surface temperature drops locally and moisture from the room air can precipitate. As a result, mould can form on the surface and cause subsequent damage to the object.

Slim reveal insulation with SLENTEX® can minimize this thermal bridge and therefore reduce moisture condensation and the tendency to mildew – making damage-free interior insulation possible. An example is illustrated below.

Preserving small balconies
Slentex balconiesWhen installing a well insulating EIFS on a building with small balconies, the EIFS could reduce the floor area of the balconies considerably such that they are no longer walkable. One option is to detach the balconies from the building and move them in front – another option is to use SLENTEX® in the balcony area to preserve their purpose with minimum effort.
Electric/water installation within conventional EIFS

In many retrofit projects, various measures to improve the building comfort are carried out together. One is the thermal performance of the facade and another popular one is the modernization of installation pipes for water and electricity.

Combining SLENTEX® with conventional insulation materials allows a channel for pipe installation to be created within the EIFS layer, thus avoiding extensive dusty indoor cutting works. One possible variant is illustrated below.
