Insulated Homes Turn Into Ovens

Super-insulated homes, built to keep warmth in during winter, are turning into sweltering ovens in summer—thanks mostly to south-facing windows. Engineer Kieran McCarthy explains that it’s not the insulation failing, but how heat gets trapped inside after sunlight floods through double-glazed glass. He recommends practical fixes like UV-blocking window films or small canopies to reduce solar gain, rather than relying on AC. The takeaway? Insulation still wins for energy efficiency—but smart design is key to balancing comfort year-round. Support the show:Get a discount at https://solipillow.com/discount/dnn.
