What is Cork Spray?

Cork spray is a thermal insulator which comes in any colour that recovers 30% of heat lost through the walls of your home. It's a fire, mould & damp proof, breathable, flexible, weather resistant, sound resistant, insulating coating for both residential and commercial buildings.

How is cork spray made?

The bark from the Cork tree is removed, which doesn't require any trees to be cut down, with this harvesting of the bark causing the tree to absorb carbon dioxide at a faster rate as it replenishes its bark. This Cork is ground into granules, which when mixed with solvent-free resins, mineral fillers, and more, creates a natural insulating, fire, mould and damp-proof spray that can be applied to any surface. The Cork Spray offsets 4kg of carbon for every square metre we spray, with cork forests absorbing 20 million tonnes annually.

  • Mould & Damp Proof: Cork Spray is resistant to mould & damp due to it's thermal, vapour-open, and anti-fungal properties, with internal wall temperatures increasing by 3 degrees celsius when the Cork Spray is applied.

testimonials

David Hunter

"Not only has it freshened up our house, more importantly we have noticed a difference right away. The house holds the heat far longer and the boiler is running less so there is going to be a good reduction in our fuel bill. Fantastic product which will pay for itself in energy savings."

Dorothy Pugh

"SprayCork product is amazing, looks great perfect finish. I've just had my old prefab rendered and coated with it. A fantastic job."

Nick Murray

"My ground floor flat was sprayed on both the north and west walls. I chose CorkSol because of its ECO friendly benefits and most importantly its good insulation qualities. It has a lovely finish too."

Frequently Asked Questions

How long does it take to spray a house?

Of course, it depends on the side of the house, but the average sized home usually takes 1-2 days to fully spray with 2 coats.

Is the Cork Spray fireproof?

Yes, the Cork Spray is Euro class B fire rated.

Can I spray it on any surface?

Yes, Cork Spray can be sprayed directly onto any surface, once it's clean, dust-free and dry.

Is the Cork Spray Mould & Damp proof?

Yes, Cork Spray is both mould, and damp proof, with the internal wall temperature increasing by 3 degrees celsius when Cork Spray is applied to an uninsulated wall.

How can it be both waterproof, and breathable?

The Cork Spray works in the same way as an intelligent membrane, so it stops moisture vapour coming in from the outside, while at the same time allowing moisture vapour to pass from the inside.

What is the U-Value of Cork Spray?

We don’t give a U-Value for the product on its own as that is determined by the complete build of the wall. If you wish to calculate the U-Value of your wall, SprayCork’s Lambda value is 0.058W/mk. As SprayCork is one continuous skin with no joins or gaps, it improves air tightness of the walls which isn’t measured in U-Value testing.

How many colours is there to choose from?

We have a standard colour range with 28 fade resistant colours.

My property is on the coast, how does Cork Spray protect against sea salts?

Cork has evolved over millions of years in coastal areas of the Mediterranean and has become naturally resistant to sea salts. SprayCork is resistant to sea salts and algae. If your property is on the coast be aware your house/building will need to be specially washed and treated before application. This will be included in the quote.

Is there a Warranty?

The product warranty for external coatings is 25 years, and is unlimited for internal coatings The warranty covers any issues with the product failing.

Can I spray my shed or mobile home with Cork Spray?

Yes, by all means Cork Spray is great for insulating mobile homes and sheds, which would otherwise be difficult to insulate.

Is Cork Spray a better insulator on the interior, or exterior of buildings?

This is a great question and one to definitely consider when upgrading your property. SprayCork can be sprayed internally then skimmed/plastered over to create TIWI (Thin Internal Wall Insulation) at only 8mm including smooth finish and paint. Alternately SprayCork can applied externally on your home/building to refresh and dramatically improve the appearance, as well as offering a multitude of benefits. Either option gives flexibility, breathability, thermal and acoustic insulation, mould and condensation elimination and fire resistance. The performance remains the same. Both options have been tested to ISO9869 and offer around 30% energy savings on heat transfer through walls. Internal application is advisable for dealing with condensation or black spot mould and is particularly useful in heritage buildings or areas where external application isn’t possible.

Can Cork Spray be painted over?

SprayCork can be painted although this shouldn’t be necessary as it is long lasting and available in a range of colours. Care should be taken to use a paint which is breathable and as natural as possible to avoid making the warranty invalid. Painting may affect the breathability or fire resistance of the product, so we do not recommend it.
