Shaft systems
Shaft systems

We focus on quality, innovation and customised solutions.
Our shaft systems
Our shaft systems consist of a geopolymer foam (LA30) or a special vapour-hardened aerated concrete (LA90). These durable materials are extremely lightweight and can be installed quickly and easily using standard tools.
SKOBIFIX®
SKOBIFIX® is a “condensing chimney block” made from special fire rated SKOBIFIX geopolymer foam. The 1 metre long shaft elements have a tongue and groove system that guarantees quick and easy installation.


UNIFIX shaft moulding blocks are a UNIversal miracle. As an F90 shaft, they are suitable both for accommodating flue gas pipes and as a fire protection casing for solid fuels.

PORIFIX® 90 is a product combination of F90 shaft and plastic flue pipe, which has been specially developed for the target group of self-builders and is listed with leading building materials wholesalers.
