Super Silver Cavity Wall Insulation

Super Silver

Background

The manufacturer of the Warmfill ® product has been working continually to improve the performance of all their products to provide Builders with an easy answer to meeting the proposed new Building Regulations. Blue Flag ® is currently working in partnership with Warmfill ® to promote the qualities, performance and the advantages of this unique product to the House Builder Sector.

Product/System

 Warmfill ® Super Silver Cavity Wall Insulation is a Bonded Bead System which utilizes two basic components. This combines a specially manufactured grade of closed cell polystyrene thermal bead with a drying adhesive, which is coated onto the bead, during the injection process.

The special bonding agent allows the beads to flow freely until the cavity wall is completely full. The adhesive then sets and the beads are formed into a bonded heat saving mass. 
The product will not shrink, crack, settle or be unduly affected by any alteration to the outside brickwork. The unique draining qualities of the product, allow the cavity to drain, breathe and remain dry. 
The product is suitable for all non-insulated cavity walls and gives approximately 15 – 20% better thermal insulation than other products.

Benefits/Savings

The following table details the four main Cavity Wall Insulation Products manufactured by Warmfill ®. Most Cavity wall Insulation systems only achieve .040 Lambda value. The range provided by Warmfill ® however, gives a Lambda value from .040 for white Warmfill ® to 0.32 for the Super Silver. 
When considering the above lambda values, the achievable ‘U’ values on 100mm cavity widths are from .34 to .26 respectively for the same products.
