Allproof fire collar product and technical data BRANZ Appraised — Appraisal No. 1088 [2019] 

In-Service History

This product has been used in a wide variety of projects using a com floor since its launch.

Most plumbing merchants who are located in areas that service tradespersons constructing multi level buildings (i.e. Auckland city centre) now stock this item on their shelves due to its popularity.

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.
