Why Insulation is a Game-Changer in Clean Energy

Insulation doesn’t just keep homes warm in winter and cool in summer — it determines how efficiently a house performs year-round. For clean energy contractors in California, insulation is a foundational upgrade that maximizes the performance of everything that follows: HVAC, heat pumps, solar, and beyond.

Knowing how to assess and improve insulation is critical, whether preparing a home for electrification or helping a client take advantage of state and utility rebates. Our Insulation Educational Series teaches you to do it right — the first time.
