And that’s where spray cork insulation, specifically ReveCork, comes into its own.
Whether you’re a contractor wanting to offer something different to your clients or a homeowner fed up with high energy bills, now’s a good time to take a closer look at how cork could be the answer to improving home energy efficiency.
It’s easy to forget about insulation until the first cold snap hits. But summer is actually the perfect time to upgrade. There’s less rain to contend with, more stable temperatures for application and you can get ahead of the autumn rush when contractors’ diaries fill up fast.
More importantly, home energy efficiency isn’t just a winter concern. Anyone who’s lived through a heatwave in a poorly insulated home knows the misery of baking bedrooms and stuffy loft conversions. Better insulation means:
ReveCork is made from natural cork granules mixed into a resin and applied using a specialist spray gun. Once it’s on the wall (inside or out) it forms a flexible, breathable coating.
Thermal regulation: Cork has millions of tiny air-filled cells that slow down heat transfer and improve home energy efficiency. In summer, that means less heat getting through the walls. In winter, it means less warmth escaping.
Moisture control: ReveCork is breathable, so moisture can escape without letting water in. That’s a big plus for UK properties where damp and condensation can be a problem.
Weather resistance: It shrugs off rain, wind and frost. Ideal given the often-soggy British climate.
Eco credentials: Cork is a renewable, natural material.
While spray cork is great all year round, summer brings a few particular advantages.
Ever walked into a terraced house on a hot July afternoon and been hit with a wall of trapped heat? Cork disrupts the heat absorption process and improves home energy efficiency, so the walls don’t act like giant storage heaters.
Plenty of UK homes (especially older ones) have surfaces that aren’t easy to insulate with traditional methods. Uneven brick, pebble dash, stone cottages and even timber cladding… ReveCork bonds well to all of them. That’s good news for period homes in places like Bath or Edinburgh where the aesthetic needs to stay intact and planning permission may be required.
Unlike some insulation methods that involve taking down plaster or adding thick boards, spray cork is applied directly to existing surfaces. That means less mess, less time on site and no need to move out while the work’s done.
If you’re in the trade, summer’s a great time to add spray cork insulation to your list of services. Here’s why:
Eco appeal: More clients are asking for sustainable home energy efficiency materials. Cork ticks that box without compromising on performance.
Versatility: Suitable for interiors and exteriors, new builds and retrofits, domestic and commercial projects, and more.
Support and training: Spray Cork UK provides product training so you can deliver a flawless finish from day one.
Thinking about an insulation upgrade? Doing it in summer means you’ll be ready for both the lingering heatwaves and the inevitable winter chills. Plus, you’ll get:
Lower bills: With better thermal performance, you’ll spend less on cooling and heating.
Improved comfort: More consistent indoor temperatures mean no more sweating through August or shivering in January. As an added bonus, spray cork improves sound insulation to keep out noisy cars or bikes, barking dogs and anything else that might disturb the peace.
A fresh new look: ReveCork comes in over 30 colours, so it’s a chance to refresh the exterior of your home while improving home energy efficiency.
One of the big draws of spray cork is its longevity. ReveCork’s flexibility means it doesn’t crack like traditional renders, even when the building moves slightly over time. With the right application, it can last decades with minimal maintenance and keep performing at the same level throughout.
The UK’s climate isn’t just wet. It’s changeable. A wall can go from being lashed with rain in the morning to baking in strong sun by the afternoon. That constant expansion and contraction can wreak havoc on rigid materials. Cork’s natural elasticity takes it in stride.
And while much of the country gets a fair amount of rain, certain regions like Cornwall, Wales and the west coast of Scotland, take the brunt of Atlantic storms. Elsewhere, like London and the South East, it’s heatwaves that cause discomfort and higher cooling costs. Spray cork insulation helps on both fronts, which makes it a rare all-rounder render for home energy efficiency.
