We were having condensation problems…
We were having condensation problems with a metal roof and had started fitting Celotex for insulation which was not going to work. Thermofoam advised a thinnish closed cell foam to cure the condensation and a thick open cell for insulation. They were very easy to work with from advice stage, thru to instal and dealt with a monor snagging issue with no quibbles or delays. Very happy to reconmend them. Our project was a 400sq m roof on an agricultural building being converted to residential.

Thermofoam were a pleasure to work with from start to finish.we were working on tight deadlines on a new build property and decided to opt for spray foam because of its speed thermal performance and airtight was.Thermofoam managed to fully install the walls roof and floor of the house in a fraction of the time it would have taken us if using other forms of insulation. They also liaised with the building control officer on our behalf to ensure that the insulation was approved and could be used.Top marks for Thermofoam and we shall certainly use them again

Great result - couldn’t have asked for more
We chose Thermofoam for our roof insulation after comparing their prices with other quotes we’d been given. They were sensibly priced, communicated well from start to finish and the spray foam seems to have made a massive difference in abating cold draughts. Our house also seems much quieter since having the foam in our roof!

Three large loft areas with tight access
Three large loft areas with tight access. Inspected and measured quickly and job started the following week. All done in a day, the 2 operatives were great, friendly experienced and cracked on. Did a full review afterwards with us and put the hoses back to address one small (very small) missed area which was exemplary. Recommended

Quick and responsive with a very can-do approach. I had a tight deadline and a tight site ( railway Carriage). Nothing was too much trouble and the men on site were happy to work around some very tight spaces. Great job and thanks for your help
