Construction Instruction

🚨 Tiny detail. Big building science lesson.

Do unsealed nail penetrations actually matter?

We put it to the test at Ci using calibrated equipment and ASTM testing procedures to compare enclosure performance with sealed vs. unsealed nail penetrations and the results were clear:

💧 Unsealed nail penetrations leak.

Sometimes, better building comes down to getting the small details right. Building science helps remove the guesswork and turn best practices into proven performance.

👉 Are you sealing nail penetrations on your projects?

“Building science never stands still… and neither can builders.” 👊🏽🏠

Jerry Charles with Symbolic Homes in Los Angeles, CA, has now attended Construction Instruction training THREE times.

As a luxury, custom builder working on very large, highly detailed homes, Jerry explained that staying current with building technology, mechanical systems, comfort strategies, and performance details is critical to delivering better homes for his clients.

But when you only build a few homes every several years due to their massive scale, often 20-30K square feet each, gaining knowledge in the field about cutting edge technologies and top building science recommendations can be a challenge.

That’s why builders from across North America come to Construction Instruction:
✔️ To sharpen their skills
✔️ To better work with trades and subs
✔️ To stay ahead of evolving building practices
✔️ To build more comfortable, durable, high-performance homes

We’re incredibly grateful for the trust and kind words, Jerry. 🙌

The best builders never stop learning.
