|Rockwool insulation panels being installed onto the facade|
All of their systems are proprietary, according to the European Standards.
The new version of Buryat EI120, as solution for 1 meter fringe between slab concrete and curtain wall, is formed by four elements described as follows:
High density rockwool insulation panel of 50 mm thickness.
Espiga ACR: bracket between panels.
Square profile: anchorage for horizontal panel on the lower slab side.
Angled: anchorage for vertical panel internal aluminium frame.
The system is formed by a rockwool vertical panel inside the aluminium frame, afterwards two horizontal panel situated one on the top and one on the lower side slab. The lower panel is anchoraged to the slab through the square profile. The top panel is fixed between the concrete slab and vertical panel.
The rockwool panels are anchoraged to the concrete slab, in order to achieve the independence between fire insulation system and curtain wall.
Finally, the aluminium mullions are covered with a new rockwool panel through the Espiga bracket, providing continuity all across the facade. At the top area, the same rockwool panel is fixed against the vertical panel through the espiga bracket.
The free spaces between the rockwool panels and the slab concrete must be filled with intumescent sealants.
The insulation fire system integrated in a curtain wall passed the test, achieving 120 minuts of stability and integrity against fire.
