Part-L-Solutions

Keep a 300mm width wall and still meet the new 0.18W/m2K U-Value requirements!

Achieving the new Part L building regulations with SureCav25 -
SureCav25 helps to lower U-Values and reduce the wall thickness!

 

Now drive down U-Values to 0.18W/m2K and lower!

SureCav25 allows for more room in the cavity for insulation, thus enhancing the thermal performance of the wall. All the properties of SureCav50 you’ve come to rely on - but now just 25mm deep - with a guaranteed 25mm clean and moisture free clear cavity. 

 

The example shows how a 100mm overall cavity width, comprising 75mm board insulation and a 25mm clear cavity using SureCav25, can achieve U-Values as low as 0.18 W/m²K. Alternatively, a 125mm overall cavity width, comprising 100mm board insulation and a 25mm clear cavity using SureCav25, can achieve U-Values as low as 0.15 W/m²K. (Figures calculated using Kingspan Kooltherm K108 Cavity Board insulation and the Kingspan U-Value calculator)

What is SureCav and how it will save you money?

SureCav25 is a moulded, 100% recycled, polypropylene panel with spacer protrusions, forming a 25mm clear cavity and providing the perfect backing board for the stone, slate, brick and flint outer leaf. This cavity protection system ensures clean and moisture free cavities with either timber frame or traditional construction.

Concrete is deceptively expensive. SureCav can significantly lower your building costs. It forms a 25mm or 50mm moisture-free clear cavity, providing a backing board for the outer masonry leaf. This makes SureCav up to 2½ cheaper than building with a backing block. It’s also environmentally sound, producing a sixth of the CO2 footprint compared to using a concrete block backing wall.

  • 100% recycled plastic
  • One sixth of the CO2 footprint, weight for weight, when compared with concrete blocks
  • More than half the cost of  building a block supporting wall. See cost comparison here

Panel size: 1200mm (L) x 450mm (H) x 25mm deep. Yes! Just 25mm deep. This also gives the option for more room in the cavity for insulation, enhancing the thermal performance of the building envelope.

Consistent clear cavity

Now guarantee clean and moisture free cavities with SureCav25! The SureCav25 cavity backing system is used to form a consistent 25mm clear cavity width in new masonry or timber frame constructed cavity walls of domestic and non domestic buildings and is fully BBA certified. It is our experience that a clear section of the cavity should always be present in the construction of the walls. The 25mm air gap between the outer layer of masonry and the insulation, coupled with the moisture beating design of the SureCav25 panels, will prevent any water penetration. The SureCav25 panels will also hold the insulation in place, adding to its effectiveness in preventing heat loss.

 

Protect from wind driven rain

The trend being experienced towards wetter weather in the UK means greater consideration has to be given to protecting the building envelope against water penetration - especially in severe exposure zones.

Reasons to build with SureCav25 in all exposure zones:
  • Full BBA approval to form a 25mm clear cavity, incorporating a fold line in each sheet to form the corners
  • 100% recycled polypropylene sheets that are durable and will last the lifetime of the building
  • Forms a barrier to protect from wind-driven rain, incorporating a unique pod shape with a special groove for moisture protection
  • Excellent surface for the construction of any external wall masonry but shields the cavity and inner leaf from water ingress
  • Ideal for timber-frame and traditional block inner leaf, as well as SIPs, SFS and ICF construction
