- Tile Product Concrete Medium Format

A vortex is a circulating eddy of air, like a mini-tornado, caused by low-flying aircraft. The effect is to suck tiles off the roof.
The Redland 49 tile, with its ability to be fixed both top and bottom, is the first choice product used to replace roofs around Heathrow airport that have been damaged by the vortex effect.
Heathrow airport has been offering replacement roofs when vortex strikes occur for over 20 years and the Redland 49 tile is one of the few products to have passed stringent wind tunnel tests, qualifying it for use in the project.
Redland 49 is a small interlocking concrete tile that has been in manufacture for 65 years and is particularly popular in London and the South East where it is the ubiquitous tile of choice for huge areas of post-war housing.
