stem frame
System solution for double-shell masonry
This system allows the window to be installed in the outer insulation layer, eliminating thermal bridges between the window and the masonry.
The masonry and window frame, as well as the masonry and window sill, are thermally separated, and the window construction is optimally insulated.
The isotherm profile is significantly improved, as is the sound insulation.
Passive house, KfW efficiency house standards 40 Plus, 40 and 55 approved.
More living space
With this system, windows and also window-doors can be installed in the insulation layer of double-shell masonry.
According to the regulation for calculating living space (Living Space Ordinance - WoFlV), when determining the floor area (§ 3), window and open wall niches that do not reach down to the floor or that reach down to the floor and are 0.13 meters or less deep are not included in the living space.
With our system, you will be able to include windows and doors in your living space calculations in the future.
Features and benefits
Our reveal frame systems are tested and certified by FIW Munich and SWA Aachen.
We significantly exceed the requirements of the EnEV 2009.
- highly heat and sound insulating
- Suitable for passive houses, efficiency houses 40 Plus, 40, 55
- Maximum stability thanks to expanded EPS
- weather-resistant, dimensionally stable, frost-proof
- full surface contact of the exterior window sill when used with a sill system
- simplified window installation into the insulation layer
- more living space with double-shell masonry
- more interior windowsill space
- RC 2 tested according to DIN EN 1627
- High load capacity (579 kilograms)
- Fall protection TRAV according to DIN 18008
- Thermal conductivity λ = 0.0307 W (mK)
- Effective sound insulation 46 dB (Rw)
Our stem frame system can be used withRoller shutter or Venetian blind box, as well as without oneto be built.
Example calculation for optimizing living space
Residential building with 20 apartments, each with 2 French doors (101 and 251 cm wide)
Taking into account a mounting distance of 3 cm and 1.5 cm plaster when installing the front frame system without sill frame in masonry concrete 20 cm ETICS.

afrom practice
Installation example at a residential complex in Munich.
The integration of the extension frame into the external thermal insulation composite system is a nice sight.
The roller shutter boxes are designed for wall mounting.
Incidentally, ETICS panels can be installed as soon as the outer frame is installed.
100% more windowsill
Installation example in a brick wall with ETICS (External Thermal Insulation Composite System).
Interior spaces appear larger, and in the case of windows and doors, this translates to more living space in square meters.
RC 2 despite thermally insulating brick construction!
