Project name: Heathrow Vortex
Client: Heathrow Airport
Sub contractor: Richardson Roofing
Solution: BMI Redland 49
The Iconic Redland 49 tile, with its ability to be fixed both top and bottom, was the first choice product when it came to replacing roofs on properties based around Heathrow Airport that had been damaged by the vortex effect.
A vortex is a circulating eddy of air caused by low-flying aircraft. The vortex effect causes tiles to be damaged and sucked off a roof, and this issue is particularly significant as aircraft come into land.
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.
Replacement tiles need to be firmly fixed and Redland 49 tiles allow for both clips and nails to be used as required by the BRE guidance document DG467. The small format of the tile combined with this dual fixing provides the most secure fixing possible.
The Redland 49 has defined the roofscapes of London for over 70 years (since 1949 as the name would suggest). A compact and visually appealing interlocking cambered tile, the Redland 49 is easy to handle and install, offering speed, strength and economy as a roofing material.
