Homes in Ireland traditionally are built using a cavity wall construction method which incorporates an inner and outer wall with a gap, or cavity in between. They are normally constructed using block or bricks. Inside the walls cavity wall tiles are installed between the inner and outer leaf to connect the walls. Cavities are designed to ensure that rain water and moisture does not transfer from inside to outside. While the cavity is very effective at keeping moisture out many houses particularly older houses have little or no insulation between the inner and outer walls. We will fill your cavities by pumping bonded beads into the cavities either to add to existing insulation or completely fill the cavities where no previous insulation existed. Our surveyor will determine whether a partial fill or full top-up of cavity insulation is required.
