Product Options & Installation

The Stoneshield Fire Safe T Block is designed to be compression fitted into the wall junction during construction, requiring no additional fixings. It is essential to ensure the correct size barrier has been selected for the cavity width, with a minimum of 10mm compression achieved upon completion. Any cavity insulation should be cut back to maintain correct compression between the inner and outer leaf. Joints must be tightly butted to maintain a continuous fire seal. A optional DPC can be added to any size requested.
