Written by the company
Air tightness is an important factor for many reasons within a building. Air leakage can result in significant heat loss & transfer of external/internal sounds. In the majority of cases, apart from Passivhaus construction and a hand full of developers specialising in energy efficient construction, there appears to be limited understanding within the construction industry of what air tightness actually is, how to achieve it and its importance. Air leakage can account for up to half of the energy consumed for heating purposes. By insulating your loft space correctly & installing Isothane Technitherm closed cell cavity wall insulation will eradicate these issues.

excellent service
excellent service, they arranged the stored stuff in the loft very neatly and worked non-stop for an excellent icynene sparying work. Very happy with the initial results of the icynene foam layer.
Although we have not seen drastic temperatures in the UK, the temperatures in all 1st-floor rooms are almost the same. We used to have even 5 degrees variation before.
Icynene spray foam in light industrial building
We have worked with Prize Spraying to insulate with Icynene spray foam LDC-50 an entire light industrial building in East London. A real pleasure to deal with from start to finish. Lorraine, Jason and their team are very knowledgeable about their product and very professional. The application was done to exacting standards and the resulting foam layer is incredibly neat and levelled. The site was left in very tidy condition. Very pleased. Highly recommended.
Excellent service
Excellent service, very knowledgeable and great products. Quick and tidy service. Would definitely recommend for any house passive or otherwise.
Absolute first class service from start…
Absolute first class service from start to finish.would certainly recommend prize spraying to anyone.They went above and beyond what we could reasonably expect of them.Good customer service is what they are all about.
Good service from the start
Good service from the start. Easy to deal with. No pressure sales on initial inspection and gave clear information without jargon. Very honest and fair cost for the work well below another we contacted. Finished job is very good and just as expected, despite having to deal with 5 different roof spaces, 3 of them not easily accessible.
Excellent
Excellent, tidy and knowledgeable team. We spoke to many people but Prize Spraying came across as the most honest and trustworthy. They were fast, efficient and friendly. The loft is now useable, warm and dry. Would recommend any time.
Major insulation project on detached house
Prize have just completed the first part of a multiple phase project to improve the insulation in our chalet style detached house. We are delighted with the cavity wall insulation work they have done so far and as we did a ‘before and after’ thermal image survey we know it has made an improvement. The work was done efficiently, quickly and with great care to protect the property. The team have been very honest and trustworthy. When we needed parts of the existing cavity to be extracted first (Prize don’t do this themselves) they recommended a supplier who also turned out to be excellent.
We really appreciate their honest, flexible and responsive service. They have been great to work with as we plan future phases of the project on the loft, eaves and insulation behind cladding. Great work from the team: Jason, Jamie, Darcy and Lorriane on the administration. I would highly recommend them.
Great service from Prize Spraying
Great service from Prize Spraying. Easy company to deal with. Very honest and fair cost for the work by contacting them directly. Will be recommending this company to everyone we know!
A significant difference
We arranged for open cell foam to be sprayed between the pitched roof rafters, also under the flat roof of the garage - my "Hobby room". We also wanted closed cell foam injected into the cavity of the extension. The guys turned up on time and worked solidly - the first day pulling down the Jablite blocks I'd put in the garage roof and spraying there, in the afternoon they did the pitched roof and gable ends. A week later they came back to squirt into the cavity.
Immediate impressions: the upper floor of the main house is much quieter - we're not far from the M3. It also feels warmer at night.
On the ground floor, the garage shares two walls with the occupied part of the extension, and both are much warmer, last night it was around zero outside with a decent frost, the garage was around 12 C
Over the past couple of weeks, the garage has been hovering between 13-15 C, good enough to move all the paint out of the main house.
I submitted meter readings to Scottish Power when the guys were done, so we'll see what the difference is in £ and KWh
We're saving our pennies for an insulated roller door to replace the old Cardale up-and-over jobbie.
The only reason for 4 stars, not 5 is the cost, I doubt we'll see a ROI before we move, but our main priority was comfort. Can recommend this family business.
A marvalas job done
A great experienced company. My house is now so much warmer now. There isn't any cold spots in the back of the house. Recommend this company anyone who requires insulation in there cavity walls.
