Type CSV Circular Soffit Ventilator
The Circular Soffit Ventilator by Cavity Trays makes fitting ventilators into an existing soffit easier and more cost effective.
The Type CSV Circular Soffit Ventilator has a higher air throughput than most of a similar size, achieved by having louvers rather than a grille.
These provide insect resistance but promote greater opportunity for the free flow of air.
A greater flow means you need fit less of the Type CSV along the soffit to provide the requisite levels of roof ventilation, so there can be savings in cost and labour.
When louvers are fitted sloping inwardly, the ventilator is difficult to detect as the louvers camouflage the apertures so colour merges with the soffit.
If the ventilator is turned 180 degrees, the soffit has a punctuated appearance as the aperture slots can be seen.
Cavity Trays has now launched the Type CSV in handy display packs that are suitable for merchant and builder.
Each pack contains 50 Type CSV.
Type BA Cavity Barrier Arch cavitrays from Cavity Trays have been designed for use in shaped rather than horizontal cavity walls to provide opening protection. Type BA cavitrays offer total protection to the angled head, extending upwardly and outwardly to prevent the build up of concentrated water wash.
New Pyramid Weep for cavity masonry download
The new Pyramid Weep for cavity masonry from Cavity Trays replaces traditional reed straw systems. Triangular in profile, the new weep provides an aesthetically neutral means of removing water that may permeate a structure. The possible flow width of the weep is maximised due to its flat base which also allows it to bed as flat and low as possible to service water evacuation from lintels, dpc’s and trays. The Pyramid Weep is manufactured using PVCu and, as a result, will not rot.
Cavity Trays is reporting that cavity walls that support an opening using separate lintels will improve the overall thermal performance of the structural opening as the lintels do not connect and therefore do not conduct heat loss. Using this method alongside a self-supporting Cavitray and an infilling profile Cavistock enhances performances levels even further. This arrangement can promote a lintel value of up to 0.05W/mk.
Cavity Trays movement challenges the lastest British Standard PD 6697: 2010 detail that results in the entire parapet masonry above the DPC being separated from the masonry below the DPC and is not the ideal structural arrangement for a highly exposed wall at the top of a building. They outline why the use of preformed self-supporting Type P parapet cavitray is the preferred option.
Cavity Trays, already the only UK manufacturer of preformed cavitrays to hold European Technical Approval, has now secured additional approvals from LABC Registered Details (Local Authority Building Control) for preformed curved and straight cavitrays plus its extensive range of Cavicloaks.
