As building regulations tighten and the demand for greener alternatives grows, architects, builders, and homeowners increasingly seek materials that can provide high performance without compromising sustainability. Both insulating cork render and lime plaster tick those boxes, offering unique benefits to those looking to reduce energy consumption, improve indoor air quality, and contribute to environmental conservation.

What is Insulating Cork Render?

Cork is a 100% natural, renewable material made from the bark of cork oak trees. These trees can be harvested multiple times throughout their lifespan without harm, making cork an incredibly sustainable resource.

Insulating Cork Render combines the insulating properties of cork with advanced rendering technology to create a product that excels in thermal efficiency. Cork is naturally lightweight and porous, which gives it excellent insulation qualities. The key benefits of using cork render include:

• Thermal insulation: Cork render helps reduce heat loss, keeping homes warmer in winter and cooler in summer. The thermal conductivity of Insulating Cork Render is typically around 0.045 W/m²K. We have recently employed this product in a test case study, which yielded a U-value change from 2.77 W/m²K to 0.94 W/m²K, with 30mm of Insulating Cork Render applied.
• Breathability: It allows moisture to escape, preventing damp and improving the overall health of the building.
• Sustainability: Cork is eco-friendly, renewable, and recyclable, making it a perfect choice for those who want to reduce their environmental footprint.
• Versatility: Cork render can be applied to various surfaces, including brick, blockwork, and insulation boards.

Ideal for both internal and external use, insulating cork render helps reduce energy bills while providing a stylish, textured finish to building façades.

What is Lime Plaster?

Lime Plaster has been used in construction for centuries due to its durability, flexibility, and breathability. Unlike cement-based plasters, lime allows buildings to ‘breathe’, crucial for preventing moisture build-up and preserving the structural integrity of historic and modern properties.

Our lime plaster is specially formulated to provide a high-quality finish while maintaining its traditional benefits, including:

• Breathability: Lime plaster allows vapour to pass through walls, which helps prevent dampness, mould growth, and condensation.
• Flexibility: It adapts to subtle movements in buildings, reducing the risk of cracking often associated with more rigid materials like cement-based plaster.
• Compatibility with Heritage Buildings: Lime plaster is often used to restore older buildings because of its historical relevance and ability to blend seamlessly with existing structures.
• Sustainable and Non-Toxic: Lime is a natural material that absorbs carbon dioxide during the curing process, contributing to the reduction of greenhouse gases.

Lime plaster is suitable for internal and external use, making it versatile for various applications, from traditional homes to modern eco-friendly buildings.

Why choose Insulating Cork Render and Lime Plaster?

Combining cork render and lime plaster into your building project improves energy efficiency and promotes a healthier living environment. Both products are part of the movement towards more natural, breathable, and sustainable building materials that are gaining popularity in the UK construction industry.

• Thermal efficiency: Reduce energy bills by improving the insulation of your home.
• Breathable walls: Prevent damp and moisture build-up, protecting the longevity of your property.
• Eco-conscious choice: Both cork and lime are natural, recyclable, and contribute positively to environmental sustainability.
