Rockwool cavity closer systems have been developed to minimise thermal bridging at door and window reveals in cavity wall constructions. Rockwool can now offer a solution for both first-fix built-in (Rockclose) and second fix (RockReveal) applications. Both systems are fire rated and exceed the minimum requirements of Thermal Robust Details.
Usage
Rockclose provides the user with a fire rated cavity closer for masonry walls with a returning inside leaf. RockReveal is a fire rated cavity closer, which can be used in timber, metal and masonry cavity walls without the need to return the block work.
