Thermally insulated fire door system
AS 75EI
The three-chamber system AS 75 EI is used to construct thermally insulated internal and external doors with fire resistance class EI 30 and EI 60 with the possibility of installation in showcase structures, AS 75EI walls and plasterboard walls.
The system ensures full optimisation of the profiles applied by using the same sections and accessories as the classic AS 75 window and door system.
Design & functionality
Patented fire protection inserts shaped to fit the profile chambers, made from volcanic rock.
Perliterm inserts - lighter, warmer and dust-free compared to commonly used gypsum
Perliterm inserts - mechanically strong (crack and fracture resistant) for improved thermal insulation.
The first fireproof inserts on the market in a plastic envelope ensuring cleanliness and convenience of storage and use.
Single-sided glazing as in typical door systems, clip assembly on the inside.
Proprietary expanding seals clipped into thermal breaks eliminating the problem of their unsticking.
Selectable glazing position in relation to the leaf axis - so-called central glazing
Adjustable system angle for glass fixing facilitating glazing of different glass packages.
Ready-to-install, fully refabricated door arches.
Option of making smoke-proof doors with a warm panel.

Based on the solution, it is possible to construct flat walls of fire resistance class EI 60.
The five-chamber AS 110EI system is used to construct fireproof windows with the highest thermal insulation performance on the market.
The solution is used to construct thermally insulated doors that are resistant to deformation caused by large temperature differences between the inside and outside environment thanks to the use of anti-bi-metal dividers.
