Homeowner's Buying Guide — Know What to Ask Before You Buy

01

Specified to the Job

Every product is custom-specified to your exact opening, material preference, and performance requirements. We don't pull from stock — we build to the project.

02

Climate Ready

Our products are engineered for real temperature swings — from hot summers to hard winters. We specify the right U-value and SHGC for wherever you're building.

03

Trade & Builder Friendly

Full submittal packages, take-off support, and on-site coordination. We've worked enough job sites to know what builders actually need — and when they need it.

ABOUT STEELSEN

Idaho-Based. Built to
Work Anywhere.

e started Steelsen because builders and homeowners deserved a supplier who understood both the climate and the craft — without the run-around of going out of state for quality aluminum and wood products. We're based in Boise, and we work with projects well beyond it

"Every opening in a home is a chance to connect the inside with the outside. We take that seriously."

STEELSEN FOUNDER

Whether it's a custom home in the Foothills or a commercial development across the region, we work directly with homeowners, builders, and developers to specify the right product — and back it up from order through install.
