  • This field is for validation purposes and should be left unchanged.

Sprayseal is a spray applied rigid foam which forms a seamless, weatherproof barrier providing an effective and economical solution to roofing and insulation problems.

Sprayseal insulation foam is produced by combining two low viscosity liquids – an isocyanate and a resin blend – these react and expand by up to 30 times their original volume to produce a 90% closed cell structure. The formation can be varied according to specific requirements with densities ranging from 30 kg to 60 kg per cubic metre.

The non-toxic and odourless Sprayseal foam insulation is suitable for almost all situations including controlled environments and laboratories, hospitals, food processing, textile production, petrochemical and agricultural applications and has been widely used by local authorities, architects, surveyors and civil engineers. Although lightweight (normally approx. 2 kg per sq. m. at 40mm thickness), Sprayseal insulation foam is extremly rigid and will add strength to any structure. As an insulator, it is the best material commercially available and will drastically reduce heat loss giving an extremely attractive ‘pay-back’.

Sprayseal foam insulation bonds to virtually any surface and can be used in many different situations – to renovate and repair, injection work including cavity reinforcement foam and even as a buoyancy aid in marine applications – the thickness of foam can be varied to achieve any desired degree of insulation and specially formulated coatings have been developed to give specific properties – such as waterproofing, fire retarding and prevention of ultra-violet attack – as well as any chosen colour finish.

Disruption to output can be kept to an absolute minimum as Sprayseal insulation foam is applied quickly, either externally or internally. External foam and coating systems conform with BS 5242 & BS 7021.

“Your staff were courteous, prompt & cleaned up after themselves. Our only question is why didn’t we have it done years ago???!!! And so now the laborious task of putting everything back into the loft has begun. Although this has done us a favour, as we had far too much junk. Anyway, thanks very much, good job well done."

Nigel & Sue Abdullah, Hertfordshire

“Just had my roof sprayed, very pleased with the result and more than half the price to have the roof stripped and re done. Was an entertaining pleasure to have the guys from Sprayseal here.”

Jonathan Parkin

“You installed a Sprayseal system in our roof and we have deliberately waited until we had a bit of much colder weather, because it always seemed as if our upstairs bedroom of our bungalow was warmer than before, and we thought it might just be the higher temperature this autumn. Well it is not that. It is the excellence of your product. What your chap said on the stand at the Earls Court Exhibition was exactly right. Our inside roof space is much warmer – and also much cooler in the summer – Thank you very much.”

Michael Lansman

"When we purchased our property the surveyor’s report identified nail fatigue and that a conventional re-roof would be required. This would have been a costly and disruptive method. Thankfully we found Sprayseal and they offered us a cost effective alternative, and we would recommend them to anyone."

Mr & Mrs Jackson Cheshire

"Your chaps have done a great job! Hard workers and very skillful and helpful. No hesitation in recommending your company to anyone!"

Mr Haigh, Northumberland, Feb 2012

"Work was carried out to a very satisfactory standard. The workmen were great and very considerate. Many thanks."

Ms Theodore, London, Jul 2011

"The work carried out to my complete satisfaction. I was very pleased with the way they carried out the work."

Mr Snow, Hertfordshire, Jun 2011
