F.A.Q

Wall insulation is achieved by fitting insulation slabs or rolls made of mineral wool or fibreglass between the stud framework with rigid insulation boards like PIR, XPS or insulated plasterboards.

The materials used to insulate walls do not allow heat to pass through them. The closed cell nature of insulation boards restricts heat transfer, while the open cell nature of insulation batts and insulation rolls traps the heat within. Both of these insulation materials help reduce heat loss through walls.

The type of wall insulation you need will depend on the type of wall you have. Most homes these days have cavity walls.

If your home was built after the 1920s you will need cavity wall insulation. If you have solid walls you can opt for internal wall insulation or external wall insulation
 

Yes. By insulating your homes with acoustic insulation batts like Rockwool RWA45 or Knauf RS45 you soundproof your wall. Soundproofing can also be achieved using acoustic plasterboards like the Knauf sound panel or Knauf sound shield plus.

Insulation be it foam insulation boards like PIR, XPS or insulation batts like RWA45 or RS45 usually last for a long time. However, if not installed properly or if you have pre-existing moisture issues, then wall insulation can go bad.

With wall insulation, you can reduce heat loss by up to 35%. Wall insulation materials like RWA45, RS45, PIR boards, and polystyrene insulation, all of these act as barriers and restrict the movement of heat through their fabric.

Wall insulation really depends on the type of wall you have. If you have cavity wall insulation we recommend using Dritherm 32 or Dritherm 37.

If you have solid walls, then you can insulate them with acoustic insulation batts like RWA45 and RS45 or with insulated plasterboards like Knauf XPS Laminate. You can also use Actis Hybris to insulate for stud wall insulation

Yes. When you add mass to your walls in the form of insulation batts like RWA45 or Rocksilk RS45 and use acoustic plasterboards like Knauf sound shield plus and Knauf sound panel, you can soundproof walls

Cavity wall insulation helps keep heat in. You can use foam insulation boards like PIR, loose fill insulation like cellulose or insulation batts like Dritherm 37 or 32 or Superwall 36 or 32 to insulate cavity walls.

You can use the many grants sanctioned by the government to install cavity wall insulation. To know more about the eligibility criteria, please visit here

Cavity wall insulation helps to save energy and money, but only when it is installed properly. As such, cavity wall insulation does not cause any problems, but if you have pre-existing issues cavity wall insulation can worsen them.

By the 1920s, cavity wall insulation had become widely popular. It became compulsory in the 1920s

You can buy cavity wall insulation from anywhere in the UK from the comfort of you right here at Buy Insulation Online.

You likely have solid walls if your home was built before the 1920s. You can insulate solid walls internally or externally. Internal wall insulation can be done using rigid insulation boards or stud wall insulation.

You likely have solid walls if your home was bits before the 1920s. You can insulate solid walls internally or externally. External wall insulation can be done using rigid insulation boards

For soundproofing walls, you can use acoustic insulation batts like Rockwool RWA45, Knauf Rocksilk RS45 or acoustic insulation rolls. Acoustic insulation can also be achieved using acoustic plasterboards like the Knauf sound panel and Knauf sound shield plus.
 

If you have cavity walls, then yes cavity wall insulation is a good idea. It helps prevent nearly 35% of heat otherwise lost through walls.

Yes. External wall insulation will help prevent 35% of the heat that is otherwise lost through walls. It also saves indoor floor space and improves the appearance of your home.
