Cavity Wall Insulation:

Total Home Insulation are leading certified agents in west of Ireland for Supernova Silver

Bonded Bead for pumped Cavity Walls. We are NASI Certified and SEAI Approved

Between one third and one half of heat loss from a house is through the walls & Roof.

Supernova Silver can reduce this by 35%, reducing household bills & CO2 emissions, it exceeds building regulations requirements (designed to reduce energy consumption). Pumped cavity insulation is installed through a small number of 22mm holes. We make good all the holes which are patched up, all?s you do is supply the paint for us to finish. It is installed within one day, We ensure 100% cavity fill with no wastage. Our system is the most cost effective solution.

Cavity Wall Insulation is the next step after attic insulation to ensure your home is retaining as much heat as possible. Heat loss through uninsulated cavity walls can account for around 35%, meaning more money is spent on your home energy bills. The process of filling your cavity with a bead product can be done usually in a day, and only requires a fully trained two-man team. No hoses or equipment is brought inside your home. New and existing dwellings can benefit from pumped bead insulation.


  • Quick and clean to install
  • Improves the comfort of your home
  • Heat loss reduction of up to 35%
  • Installation can be carried out and finished same-day
  • Eliminates sources of condensation
  • Full fill guaranteed each time

Supernova Silver Bead Insulation

Supernova Silver's performance allows for the option of minimal wall thickness utilising materials that are traditional including dense block. In-built infrared reflectors virtually eliminate the effect of heat radiation. Read more on Supernova Silver here.

How it works

Holes of 22mm to 26mm are drilled in the outer leaf spaced 600mm to 650mm apart. The bead is injected into the cavity with the binder through a flexible pipe fitted with a non-directional nozzle. The bead packs to a uniform density inside the cavity. The process works from the bottom upwards. After injection, the holes are filled and rendered to match the existing finish as closely as possible. The team then check for any insulant that have blown up through the cavity into the loft space where any is removed.

The Problem

Condensation and mould growth on internal walls is a major concern for many Irish homes. This is due to many homes not having adequate, if any, cavity wall insulation especially against the inner leaf. This means the inner wall is always cold. When the warm air inside the room makes contact with the cold wall, moisture forms, allowing the growth of black mould and mildew.

The Solution

If the problem which causes condensation is a cold wall, then the solution is to keep it warmer. Filling the cavity inside your wall increases thermal resistance of the external wall. You will then notice a significant reduction in condensation build-up.

Save Money

Many houses in Ireland have either little or no attic insulation. As heat rises, this is where most of it will escape from. Around 25% of heat loss is experienced through the attic space. Proper attic insulation will dramatically reduce this loss and save you money after as little as 2 years.

Heat Loss in Homes
Floor 7% to 10%
Wall 25% to 30%
Roof 30% to 35%
Windows 15%
Vents 12% to 15%
Flue 8%

Key Benefits:

  • Insulation can reduce your fuel bills
  • In winter your home stays warmer for longer and more constantly
  • It will create an even temperature in your home; help prevent condensation on your walls and ceilings
  • The value of your home is increased

Understanding U-values

U-value is the term given to the energy efficiancy rating for attic insulation, windows, walls and other building components. The different components that make up e.g. a wall such as the brick outer leaf, block inner leaf and the plaster would each have an R-value. The R-valueis the resistance value to heat loss of that component. The U-value is the sum of the R-values divided into one. The lower the U-value, the better the resistance to heat loss.
