CorkSol supplies natural cork coating products for external and internal use.

What we do

SprayCork is a natural cork sprayed coating for new build and renovation projects. It provides a sustainable, innovative solution for homes, residential, commercial and industrial buildings. It gives a beautiful, flexible, weatherproof and breathable exterior finish while also adding significant thermal performance. Internally at only 4-6mm thick, it can be plastered over to solve issues with damp, mould and insulation where thicker products are intrusive or cause moisture build up in the wall.

What we can help you with

  • Sustainability - moving away from petrochemical problems and embracing bio based materials
  • External - render cracking, fading, staining or being eroded by sea salt
  • Internal - black spot mould and damp
  • Insulation - areas where IWI or EWI is too thick or can't be used due to planning restrictions
  • Breathability - locking moisture in or allowing it to build behind insulation
  • Air gaps and thermal bridging - solving the issue of specifiers focusing on U value instead of the bigger picture of where heat is lost
  • Cost - allowing for quick and effective retrofitting works that can be completed by multi skilled trades or maintenance teams

Our solution

We solve the issue of sustainability by using the bark of a cork tree as our raw material. The cork tree doesn't need to be felled to obtain the bark and the re-growth process absorbs 5x more CO2 than if it was left un-harvested.

Externally we solve poor looking render with corks natural flexibility and ability to resist staining and sea salt (due to where it grows). We can often overspray other renders without the need to knock off.

Internally, we prevent mould growth using corks natural thermal benefits. This increases the temperature of the wall, moving the dew point and stopping moisture condensing on the wall and being attracted to the food source.

We are also solving the problem with thicker IWI and EWI where these can't be used due to planning, affecting the character of the building or creating to many additional works. SprayCork can be used very thin without the need to remove skirtings, coving, door frames etc. It has been tested to prove it's vapor openness so won't increase moisture levels in the fabric of a building over time and it's spray ability means excellent coverage with no chance of air gaps or thermal bridging issues. Think of it like a insulating, breathable skin.

Benefits of working with us

Ability to overspray old render and will far out last paint or other traditional renders. Fast and easy install internally without the need to replace or adapt other parts of the building. Heat loss reduced by up to 30% which shows significant energy bill savings.
