Cavity barriers – award-winning products

Manthorpe’s REDSHIELD® cavity barriers do away with the traditional need for multiple elements to be brought together to form a single cavity barrier. Their simple yet innovative design and construction not only incorporate all the required elements for a cavity barrier in a single product, but also provide flexibility within cavities of various sizes.  In fact, our REDSHIELD® cavity barriers are industry-leading, having been named Product of the Year at the Housebuilder Awards 2020.

The REDSHIELD® cavity barrier employs a compressible clip feature to allow compression of the mineral fibre wool core to ensure a tight-fitting installation within a given cavity width. The full range consists of five size variations, each with a compression range of 20mm, meaning that cavities from 50mm to 160mm can be closed as required.

As an integrated one-piece product, the cavity barrier fulfils both the required fire integrity and insulation properties as stipulated in Part B of the Building Regulations to act as a cavity barrier and the necessary thermal break and DPC properties of a standard cavity closer.

Our cavity barriers are entirely British manufactured, as are the majority of our products; proudly supporting British manufacturing and minimising risk in the supply chain and in your project schedules.

REDSHIELD® cavity barrier – independently tested

The range of REDSHIELD® cavity barrier is available in both single and double flange versions to work in conjunction with either standard or rebated reveals. The compressed mineral fibre wool core ensures its dual purpose of thermal and fire insulation.

Recent events have pushed the importance of fire regulations to the forefront of the public’s mind and such focus demands extra reassurance. In line with Manthorpe’s ‘safety first’ approach, we arranged for our REDSHIELD® cavity barrier to undergo independent testing with Warrington Fire Research. A copy of the report confirming the success of the test is available on the product pages.

The REDSHIELD® cavity barrier is suitable for both new-build and refurbishment projects with no special fixing requirements. Thanks to its high quality materials and smart design, once installed these cavity barriers should last for the lifetime of the building.
