Spray foam insulation, specified and installed properly
Spray foam is where Green Horizon began. For over a decade we've insulated new builds, timber-frame projects, commercial and agricultural buildings and specialist spaces across the North West.

- Survey first – every job assessed before we quote
Open cell or closed cell?
We install two types of spray foam. They behave differently, carry different approvals and suit different jobs – so choosing the right one matters.
| Open cell Elastochem Insulthane 50 | Closed cell UltraTite, supplied by Elastochem | |
|---|---|---|
| Best suited to | New build, timber frame, and suitable roof, wall and floor applications | Commercial and industrial buildings, agricultural buildings, shipping containers, boats and specialist applications |
| The foam | Soft, water-blown, open cell foam with low resistance to water vapour | Rigid foam with a closed cell content of 90% or more and low water absorption |
| Thermal conductivity | 0.038 W/mK (declared, aged) | 0.032 W/mK (declared, aged) |
| Approvals | Kiwa BDA Agrément® certificates for pitched roofs, ventilated pitched roofs, flat roofs, walls and suspended timber floors | CE marked to EN 14315-1 (Declaration of Performance CPR-18-3001). No BBA or Kiwa certification. |
Spray foam in existing homes
Insulthane 50's certificates cover existing as well as new buildings, including pitched roofs and suspended timber ground floors. But not every home or roof is suitable, so every enquiry starts with a pre-installation survey. We look at the condition of the roof or floor, the type of membrane, moisture levels and ventilation before recommending anything – and if spray foam isn't right for your property, we'll tell you.
For many lofts, traditional mineral wool loft insulation is the simpler choice.
Does spray foam insulation affect mortgages?
Some mortgage lenders have concerns about spray foam insulation, particularly when installed retrospectively in existing roof spaces. Lending decisions depend on the lender, the property and the installation.
Correct specification, appropriate certification and comprehensive installation documentation are important, but they do not guarantee mortgage acceptance.
For new-build projects, Green Horizon works to the relevant design specifications and provides appropriate technical documentation.
“Absolutely fantastic company and results of my underfloor insulation. The team were so professional, friendly and courteous and respectful of my home… I would highly, highly recommend this company.”
How spray foam is priced
Every spray foam job is priced individually. The price depends on the type of foam, the thickness required and the overall area (m²) of the job – which is why we survey first and then give you a written quote.
“Made contact with Green Horizon by phone, a verbal quotation was given & quickly followed up by a very professional quote by email. I placed the order the same day and 2 days later the job was complete. All very professionally carried out from start to finish.”
“I contacted Green Horizon Energy Solutions to see if they were able to apply foam to the underside of two roofs that were condensating and causing damage to the suspended ceilings… The work on site was carried out very efficiently and has sorted out our condensation issues.”
“Work done- Spray foam insulation in cellar. We are really pleased with the work carried out by Green Horizon Energy Solutions. The end to end experience was very professional.”
