In this guide, we discuss various factors relating to spray cork, what it is and how much spray cork cost in the UK. We will also address common questions related to spray cork and its popularity.
Sustainable and eco-friendly insulation options are gaining popularity among homeowners and contractors. Cork spray insulation, also known as spray cork insulation, is a revolutionary natural breathable building coating that provides effective insulation for domestic buildings.
It is made up of organic cork granules suspended in water-based, solvent-free resins, and is weather-resistant, waterproof, and durable. Cork spray insulation can be applied to walls, roofs, facades, floors, and even pitched roofs and conservatories.
Given its popularity, it’s likely that you would want to use it in your property as well. Let’s look at it in more detail.
How much does spray cork cost in the UK?
The spray cork insulation cost in the UK can vary depending on several factors. The larger the project, the more cost-effective it tends to be on a per-square-meter basis. A thicker application generally offers better thermal performance but can cost more. Additionally, different spray cork products are available, and the cost can vary depending on the brand and quality.
According to estimates, the cost per square meter for spray cork insulation in the UK typically ranges from £60 to £100. However, please note that prices may be variable, and it’s essential to obtain quotes from professional spray painters who can assess your specific needs and provide an accurate estimate based on your project’s details.
It is important to keep in mind that the table provides approximate costs, and the actual cost may vary based on specific project requirements and market conditions. Obtaining quotes from professional spray painters is crucial to getting an accurate estimate for the cost of spray cork insulation.
Why does Spray Cork matter?
Spray cork insulation is a natural building material that can be used as an alternative to paint or stucco for exterior building finishes. It is made up of 80% cork granules and 20% water-based paint, which comes in many color options.
This innovative solution provides thermal insulation and waterproofing for buildings. Its composition of organic cork granules suspended in water-based, solvent-free resins, supplemented by small amounts of mineral fillers, stabilisers and inorganic additives make it a proven solution for insulation and protection against water damage, fire, mold, and similar problems.
Cork spray insulation is a flexible and breathable building coating that can be used on both internal and external surfaces. It provides a smooth finish that is resistant to cracking and is available in a range of colours.
Cork spray insulation is a low-maintenance and versatile product that can be used as an insulating coating, a crack repair solution, and even a damp-proofing agent. It is a natural and sustainable building material that is fire-resistant, fire-retardant, and mold-resistant. Cork spray insulation is also an excellent acoustic insulator and can help to reduce energy costs by eliminating thermal bridges.
The Benefits of Spray Cork Insulation
Spray cork insulation is a popular choice for both residential and commercial applications due to its numerous benefits. Firstly, it provides excellent thermal insulation, keeping homes warm in winter and cool in summer. This improved thermal performance results in reduced energy consumption and lower heating and cooling bills, making it an energy-efficient option.
Spray cork insulation is also eco-friendly, as cork is a sustainable and renewable resource. It can be applied to various surfaces, including walls, roofs, and even irregular shapes, providing a seamless and airtight barrier. Additionally, it offers sound insulation properties, reducing noise transmission between rooms.
Furthermore, cork is naturally fire-resistant, adding an extra layer of safety to your property. Spray cork insulation also helps prevent moisture penetration, reducing the risk of mould and mildew growth.
Overall, spray cork insulation is a versatile and effective choice for those looking for an eco-friendly, energy-efficient, and safe insulation option.
What Does Spray Cork Look Like?
Spray cork has a stucco-like appearance with a textured and soft-to-the-touch surface. It is denser than paint but comes in as many colors, and you can tint it as well.
Where Can Spray Cork Be Used?
Spray cork is a versatile material that can be used on almost any surface that is typically treated with traditional paint. It can be applied directly over all types of conventional house siding. One of the benefits of using spray cork is that it creates a nice anti-slip surface, making it perfect for decks, patios, and walkways. It also doesn’t get as hot to the touch as masonry and stone, making it ideal for pool decks.
Spray cork can also be used in interior wall cavities to seal air gaps as an alternative to spray foam, without building depth. Unlike closed cell spray foam, it is breathable and allows vapor to move through it, letting the wall assembly dry out. This application would be sprayed into an uninsulated wall cavity to seal gaps and air leakage points before installing insulation in the wall cavity. This application method could also protect wooden walls from mold and rot by acting as a protective sealant over the wood.
Spray cork can also be applied directly to interior walls to achieve a unique interior finish style.
Is Spray Cork Environmentally Friendly?
Spray cork is an eco-friendly and sustainable material that is made from cork granules and water-based paint. Cork is a highly renewable resource that is typically harvested from Forest Stewardship Council (FSC) certified forests in Portugal. The trees’ bark is harvested every nine years over its 150-250 year life span, and harvesting cork does not harm the trees.
Spray cork does not use any blowing agents, making it an environmentally friendly choice. The granules used in spray cork are typically the byproduct waste of the cork stopper industry. This means that spray cork is an excellent way to reduce waste and make use of a material that would otherwise be discarded.
Spray cork is 80% cork, which means that it reduces the release of microplastics caused by paint degradation. This is in contrast to other elastomeric paints where the 80% cork would instead be a synthetic compound. Therefore, spray cork is an excellent choice for those looking for an environmentally friendly option that is also effective and sustainable.
Does Spray Cork Add Insulation to the Home?
Spray cork is an innovative material that offers thermal and acoustic insulation to the home. Despite being applied at thin thicknesses, spray cork provides excellent insulation benefits that go beyond traditional paint or stucco.
Spray cork’s thermal insulation is measured in thermal conductivity, which is a measure of the rate at which temperature moves through a material. Vipeq, a spray cork manufacturer, claims that their cork has a thermal conductivity of 0.058. This low number means that spray cork conducts less energy, making it an effective thermal barrier.
In addition to its insulation benefits, spray cork is an excellent air-sealing material that can help reduce heating and cooling costs. By sealing gaps and air leaks, spray cork helps create a thermally efficient building. Although spray cork does not have a specific R-value, it is a unique solution to improving thermal efficiency and reducing energy costs.
