About Spray Foam
What is Polyurethane Spray Foam Insulation?
What is spray foam insulation?
Closed cell spray foam insulation is extremely versatile and can be utilised to insulate roofs, walls, floors, soffits and many more varied applications. It has been in use for more than 50 years and is becoming increasingly popular due to its excellent thermal performance, draught-proofing qualities and prevention of air leakage.
Sprayed closed cell polyurethane foam insulation is produced by heating two liquid components and dispensing them in-situ 1:1 under pressure through specialised proportioning pump and spray gun equipment.
The resulting foam then expands, sets and cures into an insulating layer, the depth of which can be varied from 20mm for anti-condensation treatments to in excess of 100mm, where very high levels of insulation are required.
This machine is driven by compressed air from our towed compressor and requires an electricity supply to power switches and the internal heater block.
A twin heated hose (65m maximum length) is fed from the van to the point of application. The two components are atomised together at the tip of the spray gun and are reacting as they are applied to the substrate to be insulated.
The flow of the rising foam seals gaps in the structure and has exceptional bonding characteristics.
The closed cell foam sets hard in minutes with a core density of 32-36 Kg/m3.
The materials installed by Isotech Sprayfoam are CFC & HCFC free foams supplied to us by the most respected manufacturers in the industry.
We are approved installers of their British Board of Agrément (BBA) and Local Authority Building Control (LABC) certificated systems. They have a Class 1 surface spread of flame rating and conforms to all relevant British and European standards.
We have developed a close working relationship with the technical services department of our suppliers and they are pleased to be involved when additional information and advice is required, such as U-value calculations and condensation risk analysis.
Data sheets, site-specific risk assessments, method statements, COSHH assessments and our company Health and Safety Policy are always available.
All our employees have CSCS (Construction Skills Certification Scheme) accreditation.
