Surecav’s latest development continues to put it at the forefront of the space race!
No stranger to the pages of Professional Builder these past ten years, Charlie Ayres certainly helped to fill a gap in the market when he came up with his BBA and LABC approved Surecav 50 Cavity spacer backing board.
The moulded, 100 per cent recycled, polypropylene panel with spacer protrusions forms a 50mm clear, clean moisture free cavity and provides the perfect backing board for the stone, brick and flint outer leaf. It quickly found favour with developers as it increases the space for extra insulation, satisfying the demand for lower U-values.
Not one to rest on his laurel leaves, and in response to ever more stringent regulations, Charlie has now developed the range to include the Surecav 25. Similar in design to its big brother, using Surecav 25 in a 100mm cavity, it is now possible to achieve a 25mm clear air gap, with 75mm of insulation to help drive down U-values to 0.18 Wm2k, plus a moisture and mortar barrier to combat water ingress from wind driven rain.
Explains Charlie: “In stone-built properties, Surecav 25 removes the need for backing blocks, reducing the wall width by as much as 150mm, which translates to 6 percent in floor space gain in a typical dwelling.
This also leaves space for extra insulation in the property if required. Remarkably, on an 80 house site, for example, the floor gain from using this product could equate to one extra dwelling. Builders will save time, money and effort compared to buying, transporting and the installation of concrete building blocks.”
Adds Charlie: “The trend experienced towards wetter weather in the UK means greater consideration has to be given to protecting the building envelope against weather penetration – especially in severe exposure zones.
The “wall” of plastic formed by the panels not only provides an excellent surface for the construction of the outer leaf but shields the cavity and inner leaf from water ingress. The unique shape of the pods directs any moisture to the outside leaf, thus protecting the fabric of the building with a 25mm clear cavity, instead of the usual 75mm required in severe exposure zones.”
It’s fair to say that Charlie has come up with another sure thing for the industry!
