With its compressed mineral fibre wool insulating core and PVCu outer casing, REDSHIELD®-R is a rebated profile cavity barrier which manages to fulfil the fire integrity and insulation requirements of the Building Regulations Part B without the need to rely on additional lining materials. As well as this, REDSHIELD®-R provides the necessary thermal break and DPC properties of a cavity closer. 

Suitable for new build and refurbishment installations, the unique construction of REDSHIELD®-R allows the product to be adaptable to suit various cavity sizes. This helps to maintain a continuous seal to a range of cavity widths especially those that may ‘stray’ in size.  

The compressed mineral fibre wool insulating core provides the 30 minutes’ integrity and 15 minutes’ insulation of a cavity barrier as per Building Regulation Approved Part B. As well as this, the construction of REDSHIELD®-R provides a solution to cold bridging problems acting as a thermal cavity closer and DPC.  

Please note that the cavity barrier is non-load bearing and must not be used as replacement for traditional methods of fixing window and doorframes to the masonry
