We had a Spray Foam installation undertaken at our home in the loft area and also underneath the sloping pitched roof area.
The installers for Thermoprotect Adrian and Roz were experienced, courteous and did a great job.
After a very long journey.
They prepared and covered everything relevant with Dust Sheets.
Throughout they communicated with me and they
ensured that we wete happy with the product used and the installation.
Incidentally they did a thorough clean up at the finish and removed all the rubbish after cutting out and replacing Plasterboard Infills.

Large Loft Conversion
I approached Thermoprotect with the hope of securing a green homes grant; to insulate a cold roof ready for a large loft conversion. Thermoprotect were extremely professional throughout and helped secure the grant. The install was great. Ashley and Richard were very good. Extremally precise and thorough during the three and a half days on site. The final result was perfect.
I subsequently encountered a little trouble with my local building control authority who were, to say the least, a little behind the times with respect to the suitability of the product. initially they stated it would not comply with building regs!!!. The Managing Director intervened on my behalf and was able to re-educate the building control officer as to the suitability of the product, highlight all accreditations with proven product facts, LBC approvals elsewhere and crucially the suitability for this install. Indeed, Thermoprotect undertake a full suitability survey prior to the install, with tailored performance calcs.
As a result the LBA were satisfied. In summary, if you want a great job with support and expert advice, choose Thermoprotect

The Company were excellent throughout.
The Company were excellent throughout.
We received advice that helped us decide what we should purchase.
Installation as done exactly to time and was completed extremely cleanly - not a spot of clearing up to do afterwards and we did not need to supply anything - not even an electricity supply or lighting.
The finished job was as specified and very neat in appearance.
Overall - thoroughly recommended.
The pitched roof insulation got done…
The pitched roof insulation got done easily. under floor insulation could not be done. The installer tried his best but could not find a way to do it. As I had just got New Laminated Floor done and there was no way he would be able to insulate the under floor without damaging the floor,which I appreciated.

Highly professional, great quality, competitive and friendly
Contacted Thermoprotect in Feb 2021. They were very professional from the start. Made a COVID safe survey, provided a competitive quote and guided us through the green grant scheme. The process was seamless, the friendly Adam and his colleague came to spray the underside of our roof in April. It took 4 days. High quality job. We now have our 10 year guarantee and are delighted with the results. I have no hesitation in highly recommending ThermoProtect.

I would highly recommend ThermoProtect as an installer of polyurethane open cell foam pitched roof insulation. The product and workmanship was excellent. As a company they were very professional both from conception to completion.
