Cavity Wall Insulation can save an average house up to £210 a year

The average household loses up to 35% of heat is lost through their walls. The solution? Cavity Wall Insulation.

Cavity Wall Insulation is one of the most common methods of insulating the home. Since 1985 cavity walls were commonly insulated when the house was built, however any homes built before this date may have partially insulated or uninsulated cavities. This means that up to 35% of the heat in your home is being lost through your walls.
It is a relatively quick and free* measure to install, meaning it has a very quick payback time (the time it takes for the savings in your energy bills to effectively pay for the measure itself)

A properly insulated cavity can save an average house up to £210 a year!

Already have Cavity Wall insulation?
Unfortunately, due to a combination of factors including rogue installers, there are many properties in the UK that have cavity wall insulation installed that were unsuitable for the measure. This has led to a number of problems across the country, including damp and condensation.
Thankfully you don’t have to just live with this forever – insulation can be extracted from the wall, and if necessary a more suitable material installed.

The Problem
Wind and driving rain against exposed brickwork can damage bricks, or more commonly, the pointing, allowing water through the wall and into the cavity. Some of the materials used in the past, particularly anything fibre-based, can absorb and hold this water, allowing it to cross the cavity to the inner walls of the home, causing damp problems.

The Solution
Extracting the cavity wall insulation is a quick, clean process, completed from the outside of the property. Compressed air is blown into the wall through drill holes, and the insulation is removed via strategically removed bricks at the bottom of the wall. Once the process is completed, the brickwork is repaired.

Replacing the Insulation
If you have a suitable cavity, and the issue was simply the material, then the cavity can be refilled with a more suitable material. In all cases, we use an oil-based, waterproof expanded polystyrene bead, which is bonded together with glue as it is pumped into the wall. This means that any water that does make its way into the cavity via cracks in the brickwork or pointing cannot bridge the cavity, and simply drains through the natural gaps in the insulation to the bottom of the cavity and into the ground, as intended.
All of our cavity wall insulation comes with a 25 year, insurance-backed guarantee.

Thrift Energy use only bonded bead
For cavity wall installations, Thrift Energy uses an oil-based, waterproof polystyrene bead, which is bonded with a glue when being injected into the cavity. This creates a material that is solid, yet has gaps for any water that may get into the cavity to drain down to the bottom of the cavity as was intended, rather than being transferred across to the internal walls. We have completed thousands of cavity wall installations with our bonded bead without any complaints of damp.

All of our installations come with a 25 year, insurance-backed guarantee.

With around 35% of all heat loss occurring through the walls, a properly insulated cavity can save an average house up to £210 a year!

Cavity Wall Insulation – how it works

• Make your enquiry by filling in our enquiry form or calling 0800 689 3415

The Effects of the Recent Floods on Cavity Wall Insulation – Act Now!

The recent floods in the Cumbria region have left people devastated after the impact of Storm Desmond. Residents effected have been warned that it isn’t just the visible interior of your home that could be effected by the flood water, damage can also occur in a properties cavity wall insulation too.

Properties that have been effected by  flood damage, if left untreated, can end up being overrun by mould which is not only damaging to the property but can also have possible health implications such as asthma. Drying should be carried out by a specialist company in order to ensure that ALL water is extracted, including water you may not be able to see trapped within wall cavities and under floorboards.

Cavity wall insulation, in particular, needs to be extracted quickly as carrying out drying procedures on internal walls will be a pointless activity if there is still water trapped in-between which can penetrate outwards over time. In addition to this, with time, lingering odours will become apparent from the sludge left in an untreated water damaged cavity. Immediate extraction of cavity wall insulation after a flood occurs should be seen as an immediate action point.

Thrift Energy can carry out both cavity wall insulation extraction and replacement in order to provide your property with the best chance of complete recovery from a traumatic event such as a flood.
