What is bonded bead cavity wall insulation? Bonded Bead allows water to pass down through the cavity and is siphoned out of the wall at the damp proof course. This movement of water out of the cavity ensures no water breaches the cavity eradicating dampness and mould issues associated with insulation that has less water resistant properties.
What is bonded bead insulation? Bonded Bead insulation is a system of injecting external cavity walls with graphite polystyrene beads and a bonding agent. The beads and adhesive combine to form an insulating barrier which significantly reduces the amount of heat lost through the walls.
How long does bead insulation last? Bead insulation fills 100% of the wall cavity, ensuring there are no cold spots. It is extremely good at insulating and you should be able to recoup your costs in energy bills within 2-3 years. It is a cheaper and more durable form of insulation than spray foam.
What is bead insulation? The bead fills the cavity full as it is pumped into the space it moves in around uneven or awkward spaces making sure every inch is filled. The process is very simple, drill it, fill it and seal it.

Are there any problems with cavity wall insulation?
Incorrectly installed cavity wall insulation causes water to seep into a property’s walls, causing structural problems and damp patches that may also manifest into mould. Most cavity wall insulation is perfectly safe – but it depends on the material used, and the quality of the workmanship.
What is the average cost of cavity wall insulation?
The cost of cavity wall insulation varies according to the type of property – but you can expect to pay about £725 to insulate a detached house, or about £475 for a semi-detached property, according to the Energy Saving Trust.
Is 100mm wall insulation enough?
Well obviously the thicker the insulation the greater the savings, so 100mm of insulation will provide bigger energy savings than 50mm of insulation. With 50mm of insulation you should expect to see a reduction in your heating bills by around 30%, but with 100mm that percentage will shoot to over 50%.

Does external wall insulation cause damp?
In summary, external wall insulation can prevent future damp on walls from condensation but it won’t mask existing problems of water penetration.
Can polystyrene be used as insulation?
Lightweight polystyrene foam provides excellent thermal insulation in numerous applications, such as building walls and roofing, refrigerators and freezers, and industrial cold storage facilities. Polystyrene insulation is inert, durable and resistant to water damage.
What are eco beads?
Ecobead Platinum is a high performance, blown in EPS bead with adhesive, typically used in external masonry walls up to and including 12 metres in height, with nominal cavity width of not less than 50mm, in new and existing domestic and non-domestic buildings.
How do you insulate an external wall?
External wall insulation involves fixing a layer of insulation material to the wall, then covering it with a special type of render (plasterwork) or cladding. The finish can be smooth, textured, painted, tiled, panelled, pebble-dashed, or finished with brick slips.
Is it worth replacing cavity wall insulation?
If the insulation gets wet or otherwise damaged by an unforeseen event like flooding, the insulation may need to be removed. An example might be where the water tank bursts or where there is a chimney fire. Here, replacement insulation is likely to be recommended once the defective cavity wall insulation is removed.
Should I avoid cavity wall insulation?
Cavity wall insulation is well known for providing a cost-effective method of reducing heat loss from your property. However, if the cavity insulation is not installed correctly then it can lead to damp problems further down the line.
