Key Takeaways

✦

When troubleshooting window condensation, consider thermal bridging in the frame, not just glass, and check humidity levels.

✦

For DIY boiler maintenance, consult manufacturer instructions and online resources, but be prepared for unexpected issues.

✦

At trade shows like IBS, prioritize a plan, seek early access opportunities, and focus on networking rather than just products.

✦

Ensure spray foam installations adhere strictly to manufacturer specifications for temperature, mix ratio, and substrate dryness to prevent shrinkage and long-term issues.

✦

For structural applications, always use screws or fasteners that are rated and approved for the specific task, consulting engineers or product documentation, especially for connectors or shear walls.

✦

When building in remote, limited-access locations, prioritize durable, weather-resistant materials and consider material transport logistics carefully, potentially opting for piece-by-piece delivery rather than pre-fabricated panels.

✦

For historic homes, assess if energy upgrades compromise their inherent drying potential; sometimes, maintaining original conditions is more durable than aggressive retrofits.
