Why choose Bonded Bead Cavity Wall Insulation?

Studies have proven that cavity wall insulation is the single most effective insulation measure which can be taken for all residential and commercial buildings, and can reduce heating costs by up to 33%.

At Ecowise we stock both KOREfill and Certainfil - by using both suppliers we can ensure our customers the best deal and the most timely service.

Physical Properties
Both KOREfill and Certainfil are types of cavity wall insulation which utilise two basic components. These components are a specially manufactured grade of closed cell polystyrene FRA thermal bead, which is coated with an air drying adhesive during the injection process. This special bonding agent allows the beads to flow freely until the cavity wall is completely fitted. The adhesive then sets, forming the beads into a bonded homogeneous heat saving mass which will not shrink, crack, settle or be unduly affected by the removal of any of the outer brickwork for alterations or window replacement.

 

Both Korefill (IAB certificate 07/0293) and Certainfil are appropriate for use with all non-insulated cavity walls, and can be installed in just half a day. Ecowise are certified by the Irish Agrément Board for the product and its installation.

 

Thermal Properties
Cavity wall insulation has an affective thermal conductivity of 0.033Wm-1K-1 and will satisfy the new building regulations. i.e. 100mm cavity = 0.27u Value. The heat retained within a building as a result of the Silver cavity wall insulation, will result in 40% more fuel savings. Bonded bead cavity wall insulation gives 15% - 20% better Thermal Insulation compared with other insulation techniques.

Installation
Our technicians can install 500 - 700 square meters per day on new build sites. The bead and bonding agent are delivered into the cavity at the correct material to binder ratio through a specially designed injection gun. Small holes are drilled in the mortar joints of the external face of the building following the approved drilling pattern. After the installation is completed the holes are carefully sealed and made good with colour matched mortar. The injection process ensures that the wall cavity is totally filled.

 

Benefits
The benefits of installing Bonded Bead wall cavity insulation are:

• There is no waste - you only pay Ecowise for what we put into the cavity. There is no cutting and shaping of boards and batting
  
• There is no storage - we bring the beads with us on the day
• Saves 6 - 10% in bricklayer's time and costs (on average €2 - €3 per m2)
• No site supervision is necessary
