Cast In Fire Collars

Allproof Cast In Fire Collars are designed to reduce the labour content of passive fire rating plumbing pipe penetrations on concrete floors that are poured on site. Simply fix the base to the formwork on site and the plumbing pipe penetration is located complete with passive fire protection. This eliminates the need for core drilling of penetrations after the floor is poured and retro fitting a fire collar or wrap. Once the floor is poured and formwork stripped, simply cut off the top of the Cast In Collar and install pipe.

Other Performance Attributes

At the core of the Allproof passive fire protection product range is the advanced intumescent technology. This enables Allproof to offer products with performance and design advantages for engineers and installers of passive fire protection products. Allproof’s intumescent material expands when exposed to heat and as its volume increases with significant expansion pressure, it produces a stable char. The intumescent char formed is a poor conductor of heat, retarding heat transfer and retaining the integrity and insulation of service penetrations through otherwise fire-resistance rated walls or floors.
