Is an effective method for adding insulation to existing walls without major renovations. This technique improves your home’s energy efficiency by filling wall cavities with high-quality insulation.
Drilling: Small holes are drilled into the exterior or interior walls, typically between the studs, to access the wall cavities. Â
Filling: Insulation material, such as blow-in cellulose or spray foam, is injected into the wall cavities through the drilled holes.
Sealing: Once the insulation is installed, the holes are carefully sealed and patched to restore the wall’s appearance.
