Type BWVC Cavitrays
The Type BWVC is a preformed DPC cavitray that vertically connects two levels within the same masonry skin without adversely interrupting bonding or coursing. Its presence prevents horizontal damp transference. It is extensively used in bay window construction where the level of the roof intersection and that of the support lintel spanning the bay is not shared and separating courses exist between them.This download is a 2D detail component created by bimstore.co.uk for Cavity Trays.This component is created in Revit 2014 and is in line with 2015 industry standards.   Polypropylene (PP) damp-proof courses and cavity trays

Type C Cavitrays
Type C cavitrays provide a harmonising yet independent DPC tray for all lintel openings. Manufactured from solid DPC, Type C cavitrays are pre-shaped to suit customer’s specific construction needs. Being pre-shaped means the installer establishes exactly what is being built into the cavity wall, whilst eliminating the dangers of distortion and misplacement.This download is a 2D detail component created by bimstore.co.uk for Cavity Trays.This component is created in Revit 2014 and is in line with 2015 industry standards.   Polypropylene (PP) damp-proof courses and cavity trays

Type E Cavitrays
The Type E is a preformed DPC cavitray which is inserted into an existing cavity wall. The Type E requires only one course of bricks to be disturbed, with just a few bricks removed at any time. The self-contained Type E cavitrays are the length of two bricks, and clip together, so long runs are easily and quickly created. Preformed angles cater for corners and piers. Each unit has stand-alone discharge via a weep. Suitable for all popular cavity widths because the cavity upstand of the Type E is hinged and adjusts to always suit the ‘as-found’ cavity width. - See more at: http://www.cavitytrays.co.uk/damp-proofing/view/1/23/1/type-e-cavitray#sthash.bLbUhA1B.dpufThis download is a 2D detail component created by bimstore.co.uk for Cavity Trays.This component is created in Revit 2014 and is in line with 2015 industry standards.   Polypropylene (PP) damp-proof courses and cavity trays

Type G Cavitrays
Type G Cavitray is available with an attached lead flashing (example 300mm.) In this example the flashing is sufficient to dress directly over the abutting roof tiles.This download is a 2D detail component created by bimstore.co.uk for Cavity Trays.This component is created in Revit 2014 and is in line with 2015 industry standards.   Polypropylene (PP) damp-proof courses and cavity trays

Type X Cavitrays
The Type X Cavitray is a preformed DPC unit with an attached ready-shaped flashing. When laid in every course of a cavity wall external skin against which a sloping roof abuts, trays provide continuous stepped DPC protection running parallel with the slope. Water and dampness in the exposed masonry skin above this stepped arrangement is prevented from gravitating downwardly below it. Thus the masonry skin is wet above the roofline but remains dry where it abecomes an internal wall.This download is a 2D detail component created by bimstore.co.uk for Cavity Trays.This component is created in Revit 2014 and is in line with 2015 industry standards.   Polypropylene (PP) damp-proof courses and cavity trays

Arches, Cavity Walls & Pinch Points

December 2018



Arches, Cavity Walls & Pinch Points

Rain blown against a cavity wall will gradually permeate the exterior masonry skin and gravitate downwardly. Where the cavity wall incorporates an arched opening, the downward flow is interrupted and water is prevented from permeating in and around the arch opening by a preformed DPC cavitray known as the Type BA (Barrier Arch). The cavitray is ready-shaped to match the opening design, and arrests the water that is then evacuated out of the structure via caviweeps, normally located both sides of the arch on the springing line - away from the opening itself.


However, where a number of arches are linked or the distance between each arch is minimal, the discharge arrangement should be reviewed to prevent water flowing into a converging point – commonly called a restricted point or pinch.

A typical example where review is necessary is where arches rise off columns, mullions, piers or cavity walling where the cavity width reduces. The water needs to be managed so flow to pinch points is minimised.

This is achieved by incorporating what is termed an Arresting Barrier. The Type Q Arresting Barrier invisibly reduces water-wash from cavity walling above a given feature or construction detail, and channels it to discharge away from its usual gravitational path. By so doing the residual onward downward water flow is minimised before any feature or construction detail is reached. In the case of multiple arches, the shelter and evacuation benefit of a higher level barrier can commonly result in less than 15% of the original water volume actually reaching converging pinch points.

Cavity Trays Ltd of Yeovil is the only UK cavity tray manufacturer awarded European Technical Approval. Water penetration and management advice is available free of charge under its Protecting the Building Envelope service.

NATIONAL AND INTERNATIONAL BEST PRACTICE BUILD DETAILS

December 2018

NATIONAL AND INTERNATIONAL BEST PRACTICE BUILD DETAILS

‘New 2019 manual is extensive, informative and contains excellent construction solutions’

Cavity Trays of Yeovil is the longest-established specialist in its field, and importantly is the only UK cavity tray manufacturer awarded European Technical Approval.

The Company is releasing a new technical handbook that contains more information and more problem-solving products than any previous publication.

Volume 28 bears the appropriate title: ‘Protecting the Building Envelope’ and contains approved national and international best practice build detail.

The official publication date is January 2019, but early release copies are being made available now, upon request.

Containing 190 pages, this latest publication addresses construction details from ground to rooftop, and lists new products and solutions including the Protective Adjustable Threshold that recently won the Housebuilder/HBF/NHBC award for Best New Building Product of 2018.


Cavity Trays approved products are accompanied with a performance warranty for the benefit of Architect, Builder and Client.

During the past three years the Yeovil-based Company has expanded its research and development department that for many decades has operated a national survey of building envelope problems and weaknesses, identifying where changes can be beneficial.

A Company spokesman explained: ‘Whilst our ongoing survey provides us with insight into the problematic areas of construction, most importantly it highlights error trends and where improvement is required.

We are regularly contacted by Local Authorities, Housing Associations and Architects seeking guidance from the survey.’

Advance copies of this latest technical manual are being dispatched throughout December.

Register your request now to receive this manual free of charge from the only UK cavity tray company awarded European Technical Approval.

Essential reading for those seeking best practice build details with an accompanying warranty - from the longest-established company in this specialised field.
