That New Attic Insulation? It's Probably Installed Wrong

Send us Fan MailYou can drop thousands on blown-in attic insulation and still live with drafts, a scorching second floor, and energy bills that refuse to budge. The uncomfortable truth is that insulation is not an air barrier. If air can move through your attic floor, fiberglass will not stop it, it will only hide it. We walk through the one rule that changes everything for home energy efficiency: seal first, insulate second.We break down how the stack effect turns your house into a chimney, pushing warm air out through attic leaks in winter and pulling hot attic air down into living space in summer. Then we get specific about where those leaks actually are: top plates along every wall, recessed can lights, plumbing and wiring penetrations, attic hatches that fit like loose drywall, and even gaps around HVAC boots. We also talk about indoor air quality, because the same airflow that wastes conditioned air can drag dust and insulation particles into your home.To prove the point, we share a blower door test case study where air leakage stayed exactly the same before and after adding insulation. That is why skipping attic air sealing can become the most expensive shortcut: fixing it later may require vacuuming out new insulation just to reach the leaks you needed to seal in the first place. We close with a simple checklist mindset: air seal, confirm attic ventilation from soffit to ridge, then insulate to the right level for your climate zone (often around R49).🆓 FREE Attic Air Seal & Insulate Guide:👉 https://buymeacoffee.com/csninja/e/478323📖 Seal First, Insulate Second: 👉 https://buymeacoffee.com/csninja/e/546355🛒 DIY Store — Professional-Grade Materials:👉 https://supply.crawlspaceninja.com📞 Book a Personal Consultation with Michael:👉 https://buymeacoffee.com/csninja🛠️ PRODUCTS FOR ATTICS:• Spray Foam Kits - https://supply.crawlspaceninja.com/collections/insulation • Attic and crawl space fans - https://supply.crawlspaceninja.com/collections/fans• Attic Hatch cover - https://amzn.to/4nwUMtj• Solar Attic Fan - https://amzn.to/2Le6o4U• Radiant Barrier - https://amzn.to/4ohWfnK• Recessed Light Cover - https://amzn.to/3ft67ch• Flir C2 Thermal Imaging Camera: https://amzn.to/2Wc5CKO• Smoke Pen: https://amzn.to/49bUS69 • Laser Temperature Meter: https://amzn.to/4qT34hZ**Disclaimer:** This information is for educational purposes only.
