What is SureCav?
The SureCav Cavity Wall Spacer System is a black, injection moulded, recycled, polypropylene sheet, with raised spacer protrusions at 260 mm centres. The sheets interlock with plastic joining H-section profile strips at all edges. Corners are formed by folding the sheet along the bend line.
Measurements of each sheet:
Depth: 50mm (SureCav50) or 25mm (SureCav25)
Sheet thickness: 2mm
Horizontal strips length: 900mm
Vertical face strips length: 400mm
will i need washers, and if so how many?
Washers are recommended for fixing the SureCav panels to timber-frame buildings. The whole SureCav System can thus be fixed to the frame ahead of the masons, adding extra protection to the timber-frame. We would suggest 5 washers per panel, one in each corner pod and one in the centre. They can be purchased in bags of 50.
WHAT FIXINGS SHOULD BE USED WITH EXTERNAL TIMBER FRAMED WALLS?
SureCav Limited do not supply fixings with the seal washers. To comply with Local Authority Planning Departments and NHBC Standards (6.2: External timber Framed Walls) M10 wall ties and their fixings should be of austenitic stainless steel, comply with the BS EN 845 and be capable of accommodating anticipated differential movement.
How many sheets to a pallet?
One pallet will contain 300sheets of SureCav25 or 200 sheets of SureCav50.
Are there any other products on the market that do the same job as SureCav?
SureCav is the only product that carries BBA certification that can successfully replace concrete backing blocks or shuttering and still maintain a moisture and mortar free cavity. Our unique patented system forms a 50mm cavity, saving time and money. SureCav25 is the only product available that allows a permitted 25mm residual cavity, approved by BBA & LABC and accepted by NHBC.
SureCav is approved by the British Board of Agrément (BBA certification No. 04/4154). View certificate
Do you supply wall ties and wall tie clips with the system?
No. The SureCav system comprises panels and the joining strips. It is the customer’s responsibility to supply ancillary items and ensure that best building practice is maintained.
How many joiners do I need?
On ordering, we need to know the number of sheets of SurerCav you require (calculate by dividing the no. of sqaure metres of wall area by 0.54). Sufficient horizontal and vertical joiners will be sent with the order.
Please note: The 900mm joining strips are to be used for the horizontal joints. Cut a long joining strip up to a wall tie and use the off-cut to start the next section. The 400mm joining strips are designed to exactly fit the vertical joints of the SureCav panel.
SureCav can be delivered to site within 48/72 hours..
Will it protect against wind driven rain?
By building with the SureCav panels instead of a using a block leaf you are providing a barrier to protect from wind driven rain. The "wall" of plastic, formed by the SureCav panels not only provides an excellent surface for the construction of the stone wall but shields the cavity and inner leaf from water ingress. The unique shape of the SureCav pods directs any moisture to the outside leaf, thus protecting the fabric of the building... >>more
Is it environmentally friendly?
SureCav is 100% recycled polypropylene. Instead of ending up as landfill or incineration material, SureCav is manufactured by injection moulding process to produce a building material that shows we care for the environment. SureCav comes out on top in reducing the Embodied CO2(ECO2) footprint in new buildings as well as being 100 times lighter than concrete blocks, making site management and movement of materials much easier... read more
Will I save money by using SureCav?
By choosing SureCav you could be saving the difference of £20.96 per square metre, compared to using a block suport wall which, for 200m2 would be £4,138. Also, don't forget that the time saved using SureCav results in a faster build, estimated to be 10 working days on an average four bedroom house... read more
Can I use Surecav with SIPs panels?
Yes, SureCav still provides the best means of forming a cavity, an essential element in construction. The external leaf of stone, flint, brick or slate can then be completed with ease. Structural Insulated Panels (SIPs) offer a modern, cost-effective, environmental and energy efficient solution to building construction. A SIPs building is constructed by assembling pre-manufactured panels which are heavily insulated, often eliminating the need for additional insulation. The panels are very strong and used in external and internal walls. The ties are fixed to the outer face of the SIP panel with a stainless steel screw.
