Cork Adhesives & Fixings

Cork Adhesives & Fixings — Natural Acoustic & Thermal Insulation

Cork is one of nature's most remarkable acoustic and thermal insulators. Harvested sustainably from cork oak bark without felling the tree, cork's unique closed-cell cellular structure — comprising millions of air-filled cells per cubic centimetre — provides natural sound absorption, vibration damping and thermal resistance that synthetic materials struggle to match. Our cork adhesives & fixings products bring this exceptional natural performance to residential, commercial and industrial applications across the UK.

Key Features

• Natural sound absorption: Cork's cellular structure absorbs acoustic energy across a wide frequency range, reducing both airborne and impact noise
• Thermal insulation: Thermal conductivity λ = 0.040–0.045 W/mK — significantly better than timber flooring substrates
• Sustainable and renewable: Cork is harvested every 9–12 years without damaging the tree, making it one of the most environmentally responsible building materials available
• Resilient and durable: Cork recovers to approximately 90% of its original thickness after compression — maintaining acoustic performance over decades
• Hypoallergenic: Naturally resistant to mould, mildew, insects and allergens
• Lightweight and easy to handle: Far lighter than rubber or mineral wool products of equivalent acoustic performance

Applications & Use Cases

Cork acoustic products are specified across a wide range of residential, commercial and specialist applications:

• Domestic flooring underlay: Under laminate, LVT, engineered timber, parquet and solid hardwood floors — adds ΔLw 8–18 dB impact sound improvement
• Wall and ceiling acoustic treatment: Cork tiles and boards provide NRC (noise reduction coefficient) values of 0.2–0.6 depending on surface texture and thickness
• Thermal underfloor insulation: Between floor joists or under screed, providing U-value improvement alongside acoustic performance
• Craft and creative applications: Notice boards, pinboards, display areas, acoustic wall art
• Commercial and retail environments: Acoustic wall panels, flooring underlays, vibration isolation pads

Standards & Compliance

Our cork products are specified in acoustic designs conforming to Building Regulations Approved Document E, BS 8233:2014 and BB93. While cork products alone are rarely sufficient to achieve full Part E compliance in separating floor constructions, they contribute meaningfully to complete acoustic systems when combined with high-density rubber underlays, acoustic mineral wool and floating floor assemblies.
