Recycled Plastic Loft Insulation Installation in Reading Sophie approached us to renew her old insulation, and after discussing the best option for her home, she chose SupaSoft. We began by removing the old insulation and thoroughly vacuuming the loft floor to eliminate fibers and debris. We then installed 250mm of SupaSoft insulation, added eaves vents for proper ventilation, and completed the project with an 8.64m² raised store floor for additional storage.
