Construction Instruction

💧 Most wall failures don't happen because the window failed.

They happen because the details around the window weren't treated like a complete water management system.

That's why so many costly callbacks come down to flashing, sequencing, drainage, and installation—not the products themselves.

If you're installing windows, here are 5 reminders worth keeping top of mind:

✔️ Flashing is a system, not just a product.

✔️ Build the sill so water has a clear path back out.

✔️ Integrate flashing properly with the WRB.

✔️ Design assemblies that can dry, not just resist water.

✔️ Don't ignore the bottom details. Weeps, drainage gaps, and clearances often determine long-term performance.

The difference between a wall that lasts for decades and one that creates warranty headaches is often a handful of installation details.

👇 What's the most common flashing or water management mistake you still see on jobsites?

We hear this all the time in our building science classes.

But what if the opposite is actually true?

High-performance isn't about adding more products or making homes more complicated. It's about making smarter decisions from the very beginning.

When you understand how a home works as a complete system, you can often improve:

🏠 Comfort
💨 Indoor air quality
🔨 Durability
⚡ Energy efficiency
..without driving up construction costs.

In many cases, better building science actually helps reduce costs.

✔️ A tighter enclosure can allow for smaller HVAC equipment.
✔️ Better design can reduce warranty risks and callbacks.
✔️ Energy modeling can reveal more cost-effective ways to meet energy codes.
✔️ A skilled Energy Rater can help optimize performance.
