Radiator pipe guides and seals – increased thermal efficiency


Manthorpe’s radiator pipe guides and seals create an impermeable barrier at the point where radiator pipes meet and pass through walls. Gaps left around pipes allow heat to escape and colder air to enter, reducing efficiency, increasing energy costs and possibly resulting in failure of the building pressure test. Our radiator pipe guides and seals have been designed in response to the Revised Part L of the Building Regulations regarding air tightness. The radiator pipe guides are designed to work with the increasingly popular plastic pipes and the custom design of the radiator pipe seal eliminates gaps through which heat might be lost.

The range of radiator pipe guides and seals is suitable for multiple wall types and radiator sizes. Twin pipe units are available for smaller radiators on both block and stud walls, and for larger radiators. A pair of single pipe units eliminate possible sag below the radiator and avoid any possible clash with a third, central radiator bracket. All of the radiator pipe guides work to prevent kinks or twists in pipework, creating a neat and tidy finish.


Radiator pipe guide – multiple flexible options

Our radiator pipe guides and seals are supplied in boxes of 20 and can be installed by a single person. Multiple fixing points on all types of seal mean secure fastening to surrounding structure contributing to the seal’s airtight effectiveness. Our product range is suitable for 10mm diameter, flexible plastic pipe.

Our radiator pipe guides and seals 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.
