Cavity trays for door and window openings

• One-piece seamless mouldings eliminate the need for site fabrication to prevent errors through poor workmanship
• Tailor-made to order – manufactured to suit exact customer requirements with delivery to site usually within 10-14 working days
• Any size, type or radius of curve can be fabricated
• Can be supplied in two or more sections to allow adjustment on site and easily compensate for building tolerances
• Easy to handle, flexible, tough, durable and puncture resistant
• Fully compatible with all Timloc DPC and cavity tray systems
• Can be used for multi-storey or high loading applications – will not extrude under loads up to the point of compressive failure of wall
• Wide range of standard components with special, tailor-made accessories also readily available

• Satisfies all NHBC requirements
• Manufactured to BS EN ISO 9001 and BS EN ISO 14001
• Complies with all relevant Building Regulations
• Meets all relevant British Standards

• All products are vacuum formed in 2.0mm thick medium density polyethylene – virtually indestructible in normal use.
• Available in black only.

• Under normal circumstances the arch and bullseye cavity tray are positioned so that the upstand fits between the door/window frame and the external brickwork. After installation, the upstand can be trimmed back flush with the frame and sealed with exterior mastic in the normal way.
• Weep holes must be provided at the base of the arch cavity tray at both sides of the opening. These can be formed by installing a purpose made Timloc plastic wall weep unit (product 1143/Invisiweep).
• When the arch and bullseye cavity tray is supplied in two or more sections, each section fits to the next by means of a lapped joint that is sealed with butyl mastic tape. Surfaces must be clean and dry otherwise a good seal will not be formed.
• Arch and bullseye cavity trays are usually supplied with an integral flap which builds into the inner leaf to ensure it is held securely in position. If building-in is not possible. For example, with a timber frame construction, the cavity tray flap should be mechanically fixed to the inner leaf.

Arch cavity trays are made to order, so please supply full construction details. Ideally these will include a fully dimensioned drawing showing door or window opening size and wall construction details. If this is not possible the minimum information required is:

• Thickness of outer leaf and cavity width
• Clear opening width and height of door or window opening
• Radius of curvature
• Position of spring line

With this data, Timloc will be able to produce and despatch a dimensioned drawing for your approval.
