Standard fiberglass batts between studs leave a massive gap in a home's defense: the studs themselves. Every wooden member acts as a thermal bridge, conducting heat directly through the wall and bypassing the insulation. Continuous exterior insulation wraps the entire building like a blanket, eliminating these cold spots and significantly reducing energy bills.
Rigid Foam and Air Barriers
Products like polyisocyanurate or extruded polystyrene provide high R-values per inch and can also serve as your primary air barrier when taped correctly. This dual-purpose approach simplifies the building assembly and creates a much tighter envelope. It is the difference between a home that feels drafty and one that maintains a rock-solid internal temperature.
Protecting the Structure
By moving the dew point to the outside of the wall assembly, continuous insulation prevents condensation from forming inside the wall cavity. This protects your framing from rot and mold, ensuring the home remains healthy and structurally sound for generations. It is a professional-level upgrade that pays for itself in both comfort and longevity.
