Cavity Trays Ltd produce a range of standard and non-standard products including cavity closers, physical damp proofing cavity trays, flashings, membranes and barriers, cavity ventilators and accessories. Cavity Trays Ltd is the only tray manufacturer awarded European Technical Approval. Approved cavitrays with Agrement Certificates are manufactured to a quality management system conforming to ISO 9001:2008. Cavitrays have high performance categorisation and are accompanied with product liability. This benefit is offered as standard when you specify and use Cavity Trays Limited. It provides an important schedule of protection. Preformed cavitrays promote a known and reliable quality of build. Cavity Trays Limited is the only manufacturer offering systems with tray upstands which adjust to suit the actual cavity width encountered. Thus the cavitrays are always compatible, accommodating the real 'as built' cavity width rather than the 'should be' width. The range embraces gable abutments, changes of level, stopends, weep/vents, circular windows, common openings, radon/methane membranes and cavity barriers, etc.
