General
To validate product insurance, the Gebrik system can only be installed by suitably qualified installation contractors, using all components supplied as part of the Gebrik system. Please contact our Commercial Dept to obtain an appropriate list of installers.
Fixing
Gebrik can be applied to many substrates, including clay or concrete masonry, light gauged steel frame walling or timber frame walling, using the appropriate quantity and type of fixings. The system is applied to a solid background so where either steel or timber stud walling is used, an exterior grade board should first be securely fixed to the vertical studs (typically at 600mm centres) and the Gebrik system can then be applied to the board.
The number of fixings for each component depends on the exposure of the building, i.e. typically the height and wind pressure on the finished façade.
| h = 0 - 10m: | use 9 fixings (3 rows of 3) | W = 2301 Nm² |
| h = 10 - 18m: | use 12 fixings (4 rows of 3) or (3 rows of 4) |
W = 2565 Nm² |
| h = 18 - 65m: | use 16 fixings (4 rows of 4) | W = 2831 Nm² |
If there is any doubt about the type and length of fixing, please contact our Technical Department for further advice.
Thermal Performance
Gebrik is designed to improve the thermal performance of a building and uses expanding polyurethane (PUR), with pentane as the blowing agent. Hence the insulation is CFC and HCFC free and meets the BREEAM credit POL1 relating to the GWP of blowing agents for insulation.
The lambda (λ) value of the insulation can be taken as 0.029 W/mK (min 40mm).
The lambda (λ) value of the brick slips can be taken as 0.5 W/mK (min 20mm).
The system can be supplied with up to an additional 60mm insulation (in 10mm increments) laminated to each component or fixed through (up to) 60mm additional insulation.

Solid Wall or Cavity Wall Construction?
In tests Gebrik is proven to resist the passage of moisture therefore a cavity is not required, whether applied to a masonry or framed substrate. However this should be agreed with the appropriate buildings insurer at the design stage.
Please find herewith our generic details for the application of Gebrik to various substrates - with and without a cavity. Please contact us if you require assistance with a particular detail that is not featured.
