Non-combustible ETICS on the facade socket part with Foamglas insulation
On fire walls and in the area of escape routes, the building regulations require the use of non-combustible building materials.
(class of resistance to fire A). This also applies to socket parts of non-combustible ETICS.
The weber.therm ETICS with cellular glass socket insulation is a high-quality and safe solution for this purpose.
Simple & safe to the goal
-
1. Clean suitable substrate (socket base masonry and concrete) and use a norm-compliant waterproofing coating. If necessary, use the bitumen primer weber.tec 901.
-
2. For bonding the insulation boards mix the 2-component bitumen cold adhesive Foamglas PC® 56 mixed in the specified mixing ratio.
-
3. Apply the adhesive full-surface with the notched trowel on the backside and also on one short and one long side of the Foamglas® insulation boards.
-
4. Butt and horizontal joints must be filled with the pre-said adhesive. Stagger the joints in rows. In case of transition to perimeter insulation, apply and trowel off the bitumen adhesive in such adjoining areas.
-
5. After tightening, trowel off any adhesive that oozes out of the joints.
-
6. Roughen the finished surface flat with a sandboard or a grid float.
-
7. Then sanding dust and dirt must be completely removed, preferably with a hand blower.
-
8. The Foamglas® insulation boards are anchored at least 150 mm above the planned final upper ground level with 2 screw dowels weber.therm Schraubdübel SRD-5 per board.
-
9. Apply the lightweight reinforcing mortar weber.therm 307 in a thickness of 5-8 mm on the dust-free boards and insert the woven mesh weber.therm 310.
-
10. As topcoat, apply either the mineral floated top render weber.star 224 AquaBalance or the smooth-trowelled bonding and reinforcing mortar weber.therm 300. The silicate egalizing paint weber.ton 414 AquaBalance can be used in both cases.
-
11. Earth-contacting building parts are waterproofed with the 2-comp. reactive waterproofing slurry weber.tec Superflex D 2 or the 2-comp. reactive and quick-setting waterproofing coating weber.tec Superflex D 24 at least 5 cm above the final upper ground level.
