UP TO A WHOOPING 50% HEAT LOSS THROUGH HOLLOW BLOCK WALLS!
Cavity Blocks, sometimes called 9 inch Hollow Blocks were sometimes used for the construction of dwelling houses and are particularly common in the greater Dublin area.
The reason cavity blocks were used was to reduce the construction costs as the builder only had to build one wall with cavity blocks as opposed to a standard cavity wall which consists of two walls built with solid blocks with a gap of 3-4 inches between them.
The downside of a Cavity Block Wall
By their nature a cavity block wall is bridged every 7 to 9 inches. This leads to a high risk of
- Poor heat retention
- Risk mildew
- Risk mould growth appearing on the inner walls
- Poor insulation
- Low BER ratings reducing the value of your home
How to Insulate a Cavity Block Wall
If you could look down from the top of your cavity block wall you would see empty columns.
We simply drill 18mm holes into each column and inject urea Foam into each column.
Each column is filled fully with high density foam greatly enhancing the thermal value of the external walls.
It is important to note that whilst insulating cavity blocks the full wall area will not be insulated because of the bridging in the block-work. However a similar situation arises with dry lining as all area where internal walls meet the external and ceiling meets a upper floors remain uninsulated.
