Spray cork is the ideal replacement for traditional renovation systems. Breathable, flexible, weather resistant, insulating render.

The Revolutionary Natural Breathable Render

Natural cork render for new build and renovation projects gives stunning finishes with the added bonus of energy efficiency

Why CorkSol?
CorkSol is a natural cork render for new build and renovation projects. It provides a sustainable, innovative solution for homes, residential, commercial and industrial buildings.

Recommended by Kevin McCloud presenter of TV’s Grand Designs, it offers an eco-friendly and high performance alternative for plasterers and render companies. Cork is taken from the cork oak tree but no trees are felled. Instead the bark is stripped away and this releases oxygen into the air, which reduces carbon dioxide in the environment.

That’s good for the planet. The tree’s bark grows back each time. So it’s a sustainable resource (unlike quarried materials). The raw material goes to make CorkSol.

Testimonial from a happy Client who had Cork applied last summer and has already seen a marked difference in energy bills through the last winter!

“We noticed a marked difference this winter – the house has been much warmer and our gas consumption (for central heating) has reduced by a third. I would say that is an excellent result 😊 Plus, everyone comments on how good the house looks with the new finish”.

The benefits of SprayCork render:

Moisture prevention
Adding a moisture-resistant coating like SprayCork will prevent moisture from gathering on the surface of the walls. With SprayCork, you’ll also benefit from improved insulation which will make it easier to maintain a comfortable temperature.

Protection against heat loss and damp
Thermocork is an innovative SprayCork coating which provides high-performance insulation without the hassle of cavity wall insulation or the bulk of insulation panels. Ready to put it to the test?

A natural solution for pebbledash
Whether you’re removing, refreshing or rendering over your pebbledash, Corksol’s innovative Spray Cork coating can provide a solution that’s hard-wearing and looks great. Drawing on the natural qualities of cork, our eco-friendly coating is super adhesive, weather resistant and remarkably insulative and available in a great range of colours.

Cavity wall Insulation alternative
Our SprayCork can be used as an insulator either internally or externally and at only 6mm thick won’t cause a heap of destruction either.

Flat roof solution
A cork roof coating can provide water-resistance, thermal efficiency and noise reduction for up to 60 years on your roof. That’s far more than you’ll get from any basic flat roof coating – and for far longer.

Suitable for old homes
Cork-based wall coatings can be used to significantly improve insulation in old homes. With cork being class 1 breathable, it helps the house retain heat without trapping moisture.

Save money on heating bills
Not only does a cork based render look better for longer than traditional renders, it can also save you money on your heating bills because of it’s natural insulation properties. Win win!!

And there’s more:

  • Highly durable and flexible coating to prevent cracking
  • Super Adhesive – When it’s on, it stays on covering a range of surfaces, including steel
  • Patch repairs possible (avoids costly or time-consuming whole-wall re-rendering)
  • Available in any RAL colour, to match your company branding
  • Strong thermal insulator and reduces thermal bridges
  • Good Sound Insulation – Reduction in noise and vibrations by up to 12dB
  • Fire Resistant – (Euro-class B safety rating), water resistant and breathable (this helps prevent mould and damp, gives people a healthier living and working space)

No trees are ever felled as cork is only harvested from the cork oak tree every 8-9 years and can continue producing cork for over 200 years.

This makes cork one of the most sustainable products on the planet! The Southern Mediterranean cork forests absorb more than 14m tonnes of CO2 annually and when the bark is stripped the tree releases large amounts of oxygen which replenishes the air we breath!
One of the main benefits of SprayCork is it offers an eco-friendly, high performance alternative for plasterers and renderers. Bark is taken from the cork tree but no trees are felled; instead the bark is stripped away and this releases oxygen into the air, which reduces carbon dioxide in the environment before growing back naturally over time.
Before you look into painting or rendering your property why not look at the greener choice in our CorkSol? With our proven reports you could save up to 15% on your own emissions and reduce your family’s carbon footprint!

When it comes to deciding which material to use for soundproofing, cork is an excellent choice.

It has natural soundproofing qualities as its structure is extremely lightweight and tightly filled with air. Cork also has a high Noise Reduction Coefficient (NRC) score of 0.7, which rates how effective an acoustic item is when absorbing sound. This score means 70% is absorbed and 30% is reflected.

The internal coating provides the same sound insulation qualities as panels or boards – up to 12 decibels – but without the same bulk and hassle.

As an insulating internal wall coating, SprayCork is applied in two coats of 3mm each and finished with a 2mm skim of plaster. That’s a thickness of just 8mm, while still significantly reducing the amount of sound coming into a room or building.

Work in a commercial setting for example provides more privacy between offices and also helps insulate and reduce bills!

Is your house lacking insulation?

With energy prices soaring we are all looking at ways to become more energy efficient. Corksol is a great way to achieve this and you may also be able to access a government grant as some of our clients already have!

IOM Government Grants to help insulate your property

There are grant schemes to go towards the cost of each room should you want to insulate them with Corksol and eradicate this issue all while conserving heat!

Thermal insulation plaster, refers to plaster-like mixtures which have been infused with insulative materials. A great example is SprayCork, which uses the natural thermal insulation properties of cork to make it harder for heat to pass through your walls.
SprayCork is applied in two 3mm coats, before being finished with a 2mm skim of plaster. The end result is a smooth surface which can be decorated with paint or paper, complete with insulation underneath.

Want to keep the inside of a building warm without spending a fortune on heating?

External wall insulation could be the answer! However traditional insulation boards can have issues with Damp, Eaves, Guttering, Fixtures and overall quality.

Keen to avoid these problems? SprayCork is perfect for you. When applied as an exterior wall coating it provides 7-8 times the insulation of traditional render, without the bulk of insulation panels. It’s completely breathable, so you won’t encounter problems with dampness, and we are fully trained to apply it.

Corksol SprayCork is the ideal solution for internal as well as external coatings.

As a natural product cork is breathable and has great thermo properties so can be used internally to solve issues with damp and mould.

Internal Wall Insulation
Our approved applicators use a thin layer of spray-applied natural cork, one of the world’s most incredible and sustainable natural resources. This can then be over skimmed and painted giving you the freedom to decorate over it as you please.

Sustainable and breathable natural product
Final coating is only 8mm thick so no need to worry about replacing fixtures and sockets etc.
Can be plastered over with a thin layer for a smooth finish. You are left with an invisible solution that mould or damp cannot form on.

Thermal insulation for inside your property.
Insulation is a vital feature for any building. It reduces heat loss, improves energy efficiency and can even prevent the build-up of condensation, damp and mould. As you can expect, walls play a key part in this. But how do you insulate them on the inside without requiring extensive work?

Why insulation matters for walls
Walls are a key part of every building’s thermal envelope. Along with the roof, windows, doors and floor, they’re responsible for keeping heat inside.

But as the saying goes, a chain is only as strong as its weakest link. If your walls aren’t keeping heat in, they will let the rest of the thermal envelope down. The result is a house that’s near impossible to keep warm without seeing your energy bills skyrocket.

Over time, poorly insulated walls can cause further problems with condensation, damp and even mould. As well as being unsightly, this could lead to health problems, particularly for those with pre-existing respiratory conditions like asthma.

The problem with wall insulation
When walls are poorly insulated, one of the most well-known solutions is cavity wall insulation. This is a pretty big job which involves drilling holes into a wall to inject insulation before sealing. It’s also unsuitable for any solid walls, which are made from brick or stone without a cavity.

Instead, solid walls can be insulated using boards or panels, before plastering on top of the boards. Again, this isn’t ideal because all the fixtures and fittings need to be removed. The boards are also very thick, so they eat away at the size of the room.

How to insulate interior walls easily
Thankfully, there is an alternative. SprayCork internal coating can provide an insulative layer without the need to remove fixtures or add bulky boards or panels.

Damp is a problem almost everyone has encountered at some point. But that doesn’t mean you should put up with it. As well as being pretty ugly to look at, damp walls can cause issues for your health.

Fortunately, there are some ways to stop damp coming through your walls, as this post will explore.

Getting familiar with damp walls
Damp walls are potentially more serious than you think. Aside from causing unsightly damp patches, the moisture can eventually damage your walls’ structural integrity if it’s left unresolved.

Damp walls also provide the perfect environment for mould to develop, which can trigger respiratory problems like asthma as well as increasing the chance that they will develop in the first place.

So where is it coming from? Damp walls typically arise because of one of three root causes…

Rising damp from the ground
Rising damp occurs when water in the ground under your walls rises through the wall itself. This happens through capillary action, with water absorbed through small openings in the building materials.

Damp from a leak
On the flipside, the moisture could be coming from above. Leaks in your roof or guttering can allow water to make its way into internal walls, leading to damp patches. Alternatively, the leak could wear down the external pointing, leading to water ingress over time.

Moisture in your home
The final and possibly most common cause of damp is moisture within your home. Moisture is naturally released by activities like washing, cooking and even breathing. If the moisture has nowhere to go, it could be absorbed by your walls. That’s especially true if they’re cold, with moisture naturally drawn to colder surfaces.

How to stop damp walls
To stop damp walls, first and foremost, you’ll need to tackle the root cause. That could be getting your roof fixed or having a damp proof course installed if it’s rising damp.

If the damp is coming from moisture in your home, ventilation is the first port of call. Allow moisture out by opening a window when you’re showering or cooking, for instance. It’s also best to keep your home at a comfortable temperature, above 18°C, so there aren’t any places where moisture can gather.

That said, it’s not always possible to heat every inch of your home while also letting out every drop of moisture. That’s where damp-proof walls can help. Coating your walls with our Corksol SprayCork can stop moisture gathering on them, as it’s naturally moisture-resistant.

Drawing on the natural properties of cork, the coating can also improve your home’s insulation. An insulative layer on the inside of your walls will make it easier to keep the temperature up without having to crank up the heating.

Put Corksol SprayCork to the test
If you want to stop damp coming through walls in your home or commercial property, Corksol is ready and waiting. Our innovative Corksol SprayCork coating provides an effective solution to eliminate damp walls and make your property more comfortable.

Does your property suffer from black spot mould? Aside from being unsightly, it can contribute to respiratory problems and other health issues. It goes hand in hand with fuel poverty, and a poor quality of life more broadly.

While there are various solutions to black spot mould – from ventilation to simply cleaning and removing mould – none offer the same long-lasting efficacy as SprayCork. Read on to find out why…

How does SprayCork combat mould?

Once mould has been fully cleaned off walls, SprayCork can be applied to make sure it doesn’t come back. The fine-grain solution is sprayed on in two 3mm coats. That’s topped off with a standard 2mm skim of plaster.

Sounds pretty standard, right? Here’s what makes SprayCork so special…

1. Mould-resistant
First and foremost, it works! Cork is naturally mould-resistant and breathable, so it prevents moisture, damp and mould from gathering on walls for good. That means no more worrying about mould coming back, or scrubbing away to clean it off.

2. Insulation
Tests have shown that SprayCork can reduce heat loss through solid walls by up to 30%. That makes the wall itself warmer, so it doesn’t attract condensation, but could also create a cosier environment and reduce heating bills.

3. Uniform coverage
Cold bridges are ideal for damp, mould and heat loss. Put simply, they’re areas where insulation is insufficient because of poor coverage. Because it’s spray applied, SprayCork will cover all areas with no problems, including window reveals and internal corners.

4. Discreet
As explained above, SprayCork’s total depth is 8mm including the skim of plaster. That means, unlike other insulation options, it doesn’t eat away at the size of a room. There’s also no need to adjust or reposition existing fittings like plug sockets, light switches and radiators.

5. Quick
On top of all the other benefits, SprayCork application is impressively quick. An entire house can be treated in as little as two days. That’s thanks to its fast spray application, as well as our trained network of Approved Applicators.

6. All natural
When you’re combatting mould to avoid breathing difficulties, the last thing you want is synthetic chemicals being released into your home. SprayCork is a natural cork render, so there’s no need to worry about indoor air pollution.

7. Sustainable
Last but not least, SprayCork is eco-friendly. Cork is harvested by stripping bark with no need to fell trees. As the bark regrows over the next 8-10 years, the trees absorb more CO2 than before. As a result, every square metre of SprayCork applied actually offsets 4kg of CO2 emissions.

What are you waiting for?

SprayCork is a fast, natural, discreet and effective solution to eliminate mould for good – with the added benefits of sustainability and better heat retention going forward. Whenever you’re ready to combat mould, Corksol’s national network of approved applicators is on hand to help.
