Structural Reinforcement – Success Story

The Project

Mr Robinson approached ThermoHome because he had concerns over the longevity of his roof and therefore wanted to explore options to future-proof it for the long term. Living in a coastal location, susceptible to high winds during winter storms, the roof was in good condition but it was clear that perhaps if left, over time, it would begin to degrade.

The Survey

When we visited the property, Mr Robinson showed us the loft space. There was evidence of moisture sitting on the underside of the roof and this was as a result of no roofing membrane, something that is essential to protecting the internal integrity of a property if roofing tiles slip, break or deteriorate.

Other than a few minor issues, the roof was actually in excellent condition with very few concerns. The property had fibreglass insulation installed to the loft floor and this made the storage of belongings very difficult. During the survey, we noticed that the fibreglass insulation had deteriorated significantly and was just a thin, dusty layer of insulation that did not achieve the full coverage of the loft floor in order to prevent heat loss.

The Specification

The obvious product choice was our high density ThermoFoam closed cell application, direct to the roof tiles at an average depth of 50-60mm. The high tensile strength of the closed cell foam would completely bond the roof tiles and prevent future slippage or lifting in the event of high winds. Due to the permanent nature of this application, we explained to Mr Robinson that the closed cell foam would protect his property for the guaranteed minimum of 25 years, however, in the event that he decided to replace the roof in the future, it would be a very hard task for a roofing company to remove the tiles without having to cut the closed cell foam from the tile.

Despite the issues in removing the foam at a later date when the roof is replace, Mr Robinson wanted to enjoy the benefits of a structurally sound roof coupled with the thermal benefits of the closed cell in reducing heat loss and therefore reducing the energy costs of the property.

Able to see the clear benefits of the proposed solution, an installation was requested and we managed to book the property in within a few days of the quote being accepted.

The Installation

Not every loft is the same so it’s always hard to predict how long an installation would take. In this instance, access to the loft was good, the loft had mostly been emptied of belongings and the area to insulate was around 65 square metres. On the day of install, our team arrived at 9am and set about laying protective sheeting throughout the walkways up to the loft space. To leave a nice finish to the closed cell foam, rafter faces were taped with masking tape, meaning that there would be no over spray with the tape being peeled off post install to leave a neat and tidy job.

Parking was a small issue as the property was located on a very steep hill with narrow lane, however, the team managed to park in a space behind the property and run the 45 metre spray hose through the back door and up into the loft. In total, the install took 7 hours from arrival to departure and this meant that within a day, Mr Robinson had a clean, dry, structurally sound and well insulated loft space.

Client Feedback

“Spray foam insulation wasn’t something I had considered for my home until I had seen an advertisement on the internet. I knew that my roof wasn’t in bad condition, although I suspected that in the future, the wear and tear of time would mean that I would have to replace it. The surveyor fully explained the product, the process and the likely results and this was enough for me to make my decision!

Following the install, I noticed that the loft space felt quieter and better protected from strong winds. The house immediately felt more ambient and I was turning my radiator down much sooner in the evenings than before the installation. The most surprising result for me was the reduction in my energy costs. Since installation, my average annual heating costs are 27.4% lower and I can link this directly back to the spray foam installation”
