Yes. Insulated plasterboard (PIR, phenolic, or graphite EPS bonded to plasterboard) reduces heat loss through uninsulated solid walls by 60-80%. This typically improves EPC ratings by 10-20 points, may qualify the property for ECO4 or GBIS retrofit funding (subject to eligibility), and reduces heating bills by £200-£500 per year for a typical Maidstone three-bed terrace.
It is the standard energy-efficiency upgrade for Maidstone's Victorian and pre-1920s housing stock. Solid 9-inch brick walls have a U-value of about 2.1 W/m²K uninsulated; adding 50-80mm insulated plasterboard brings that down to 0.30 W/m²K or better, meeting current Part L retrofit targets.
For Maidstone homeowners, this is one of the most cost-effective energy upgrades available. We handle ECO4/GBIS paperwork for eligible properties.
