Reduce heat loss by up to 30%
With a coating that’s just 6-7mm overall thickness
SprayCork isn’t your workaday internal wall insulation. The cork-based coating provides impressive heat retention without eating away at your usable space. Two coats of SprayCork are applied before a plaster overskim, with the final solution just 6-7mm overall thickness.

Internal wall insulation FAQs
Can I decorate on top of my insulation?
Absolutely. SprayCork is finished with a plaster overskim, so you can decorate once everything has fully dried. We usually recommend waiting a couple of days, but our team can advice on timeframes and the right conditions.
How long does it take?
The time it takes to insulate internal walls depends largely on the size of the property, size of the walls and number of walls being insulated. Fortunately, SprayCork is quick-drying, so there’s no need to leave several hours between coats. Some jobs can be completed in a single day, while larger properties will need multiple visits.
Where do you cover?
The Good Plastering Company is based just outside of Guildford, giving us easy access to all parts of Surrey and the Surrey-Hampshire border. This includes Woking, Weybridge, Dorking, Redhill, Aldershot, Fleet and Basingstoke.
