🌳 What Is Cork Insulation?
Cork insulation is made from primarily from finely ground granulated cork mixed with a water-based acrylic or resin binder. The result is a natural thermal and acoustic barrier that regulates temperature and moisture far better than conventional insulation boards.
At aPlastering, we install both cork insulation boards and Spray Cork (ReveCork) across Walsall, Wolverhampton, Sutton Coldfield, Lichfield, Cannock and Brownhills, helping homeowners create warmer, drier, and more sustainable homes.
💚 Why Homeowners Love Cork Insulation
✅ Naturally Antifungal – Resists mould and mildew growth without chemicals
✅ Breathable – Allows walls to “breathe,” preventing trapped moisture
✅ Thermal & Acoustic Performance – Millions of air cells slow heat and noise transfer
✅ 100 % Renewable & Carbon-Negative – Harvested without cutting down trees
✅ Beautiful Natural Finish – Warm, tactile surface that complements heritage interiors
Cork’s natural flexibility makes it perfect for bay windows, Victorian walls, and solid brick homes common across the West Midlands.
🏠 Best Uses for Cork and Spray Cork Insulation
- Victorian & Solid-Brick Homes – Keeps breathable walls dry and warm
- Bay Windows – Stops condensation and black mould at the source
- Heritage & Listed Buildings – Improves efficiency without harming character
- Sound-Sensitive Spaces – Adds acoustic comfort for bedrooms and studios
☀️ Summer Advantage – Spray Cork for Year-Round Efficiency
When applied as a Spray Cork (ReveCork) coating, cork becomes a seamless, flexible skin that works in every season:
- Keeps heat out in summer and in during winter
- Balances moisture levels and prevents condensation
- Withstands UK weather — rain, sun, and frost
- Zero VOCs & fully recyclable
Because it’s spray-applied, it suits uneven brick, pebble-dash, stone, or timber cladding — ideal for older West Midlands homes.
🔇 Bonus Benefit — Sound Insulation That Lasts
Cork’s structure contains around 40 million air-filled cells per cm³, acting as mini sound absorbers. When used as a spray render, it reduces airborne noise such as traffic or neighbours — improving comfort without thick acoustic panels.
🧩 Why It Performs So Well in UK Conditions
Whether it’s damp winters in Walsall and Wolverhampton, or warm summer spells in Sutton Coldfield, Lichfield, Cannock, and Brownhills, spray cork keeps performing year after year.
- Won’t crack or flake with expansion/contraction
- Resists salt and moisture penetration
- Needs minimal maintenance and lasts decades
