SureCav25 savings (m2) |
£41.08 |
Overall savings: £8,217.00.
By choosing SureCav25 you could be saving £41.08 per square metre by not building with a block support wall. That's over 2.5 times cheaper than a block backing wall! With a 25mm residual cavity, there is also the option to insall additional insulation to help lower U-Values. Also, don't forget that the time saved using SureCav25 results in a faster build, estimated to be 10 working days on an average four bedroom house.
