    *Existing Schemes

    We can even help with guidance & paperwork.

  • Why do you need to do a cavity wall survey?

    We need to check to see what type of external walls you have, cavity or solid. We also need to check for already installed installation, and whether its damaged.

    This could be due to rising damp and is quite common. If rising damp is detected we can use a technique called cavity wall insulation extraction, and then damp proof the walls before the new insulation gets installed, if required.

  • What type of cavity insulation do you use?

    We use injectable bonded beads, they perform much better in cavity walls than rolled up fibre glass insulation. Bonded beads our long lasting and they meet all building regulations & standards.

  • Is caviy wall insulation flammable?

    Yes, it is flamible. However only at very high temperatures, the beads will be sandwiched between 2 walls - one external and cold, the other internal and lukewarm. The property would need to fully on fire for this to be a concern!

    The beads used inside bean bags are made from expanded polystyrene (EPS).

  • How long does it take to install?

    Normally 1 or 2 full days finishes a normal sized home. It can take longer for larger homes or commercial buildings.

  • How long will the cavity wall insulation last?

    We provide a standard 30 year warranty for effectiveness on all cavity wall insulation jobs.

  • How do you see inside the cavity wall?

    We use a borescope, we will need to drill a small hole between the bricks, in the cement and then push a flexible camera on a wire inside the cavity. We can adjust to camera and view the inside of the cavity on the borescope.

  • What is cavity wall insulation made of?

    We use EPS beads - 'Expanded polystyrene beads'. EPS is also known by its brand name Styrofoam. Polystyrene is produced in 2 forms, foamed & rigid, you can learn more about it here.

  • Does cavity wall insulation cause damp?

    The cavity wall insulation bonded beads we use our water proof, however we will only install cavity insulation to good walls which have not been damaged by damp.

  • Does cavity wall insulation make a difference?

    Yes, in alot of cases we have customers saving in excess of 40%+ on rising energy costs, cavity wall insulation in combination with loft insulation can make a massive difference £.

  • Can cavity wall insulation get wet?

    Preferably not, however they will not retain water and our water resistant. The water will run straight through the beeds and ground.

  • What areas do you cover?

    We work and provide cavity wall insulation accross Northern Ireland and greater Belfast.

  • How long is the wait once booked in?

    Due to extremely high demand we currently only offer our cavity wall installation to customers who need loft insulation as well.

    We will be adding another installation team in quarter 2 of 2023 and hope to offer this as a single service then.
