Industrial Roof Renovation
Here at Green Insulation we can advise on the appropriate application for your building.
Green Insulation UK industrial roof insulation can be applied to asbestos, metal, aluminium and most other surfaces. Consequently its applications are many and varied. From roof and wall cladding to injection work. Our foam and coating systems can be used to renovate, insulate and stop condensation and is widely used in industry, marine, petrochemical and agricultural environments. Please note that no drilling is necessary for asbestos sheets.
These foam systems, tried and tested worldwide over 30 years, have been widely used by Councils, Health Authorities, Banks, Industry and Public Companies and carry a 10 year guarantee. An application of Green Insulation UK rigid foam with a two coat elastomeric membrane to a roof, whatever the existing substrate, gives a seamless, watertight, hard wearing covering which will withstand normal foot traffic.
The fact that the foam is spray applied means that it is the best method to seal around trouble spots such as vents, upstands and drainage outlets etc.
In cases where foam cannot be sprayed on the underside of roofs or a weatherproofing solution is required we can apply our sprayed foam and coating system externally. This process entails a site survey to establish the suitability of the system for your premises.
We will arrange all necessary access and safety such as scaffold, walk boards and boom lifts to comply with Health and Safety regulations. We then clean down the roof surface and carry out any remedial works as required.
Once prepared, we spray apply the Green Insulation UK foam to the roof surface, during spraying the material quickly changes from a liquid to a rigid foam, filling all joints and cracks to give a sealed roof. Following the application of the foam we spray or brush apply an elastomeric coating which seals the surface of the foam and protects it from the damaging effects of UV rays.
Why Use Spray Foam and Coating Roofing Systems
Sprayed Polyurethane Foam (SPF) and elastomeric membranes have been used to solve weatherproofing and insulation roof problems for over 40 years. It was started in the USA and soon spread globally and it has been used in UK for over 30 years.
The main benefits of using sprayed foam and coating industrial roof renovation are:
- Minimal disruption to the daily operations within the building.
- No necessity to remove the existing roof.
- No need to drill through existing roof therefore, no release of dust or dangerous fibres.
- Sprayed foam expands into joints and cracks and immediately seals them.
- When coated with an elastomeric membrane, a completely seamless bonded finish is formed.
- Up to 90% saving on heat loss through the roof.
- Very lightweight adding very little stress to the roof structure.
- Strengthens your roof and prevents uplift by strong winds.
- A weatherproofing system which also saves money on heating costs.

What Are The Benefits of Spray Foam Insulation?
Prevents Condensation Build-up
Many older commercial buildings are constructed from corrugated cement asbestos sheets or profiled metal sheets. To fix insulation board to the underside of these sheets is difficult and almost always means that there is a gap above the insulation board. This means that vapour can pass through the joints in the boards and condense on the cold roof sheets, causing the condensation to flow down the corrugations, find a week point and, consequently, drip into the building. Spray foam insulation on the other hand is sprayed directly on to the profiled sheeting leaving no gaps or joints, it seamlessly insulates and therefore, surface condensation will not form.
Spray insulation will also seal the building so that any air that is generated within the building whether it is cooled or heated is kept within the building and does not escape into the atmosphere. This obviously improves the carbon footprint and saves money spent on energy. Another advantage over traditional insulation materials is that joints, small holes and small cracks are sealed and thus prevent leaking.
Single skin asbestos cement sheet and metal roofs are subject to significant heat loss in the winter and solar gain in the summer. Un-insulated roofs of these types are likely to form condensation on the underside, which can cause major problems for items stored in the building. It can also cause problems with slip hazards or dripping on to electrical appliances. Spray foam insulation will eradicate the formation of condensation and create a dry, warm workspace.
Saves You Money on Energy Bills
Spray insulation seals the building so that any air that is generated within it, whether cooled or heated, is kept within the building and does not escape into the atmosphere. This improves your carbon footprint and saves money that would normally be spent on energy. This also means that joints, small holes and small cracks are sealed and, thus, prevent leaking.

It Can Be Applied To Asbestos
Where asbestos is present, our spray foam will seal and encapsulate the roof sheets and, therefore, prevent the escape of fibres into the working environment.
It Can Be Applied Externally
Where the roof is leaking badly or the logistics of spraying internally are too difficult we can apply the foam externally. This will seal all the joints and cracks and give a monolithic, seamless flashing to the roof. Once the foam has been sprayed then a spray/ brush applied elastomeric or acrylic coating is applied to the foam surface to protect it from UV degradation.
