Horizontal Cavity Trays


Horizontal Cavity Trays are available with factory fitted AluFlash* or code 4 lead flashings to BS EN 12588: 2006, for use at the abutment of a lean-to or flat roof with a wall. HT trays fitted with AluFlash are supplied with 225mm flashings suitable for all applications.

Long or short lead flashings are available to dress down over the roof covering in accordance with Lead Sheet Association recommendations as follows: - long flashings: roof pitches below 30º - short flashings: roof pitches of 30º and above.

For flat roofs use the short flashing to cover the roof upstand by a minimum of 75mm. Where high-level ventilation is required, use HT Trays with short flashings and the MR50 Monovent.
