Expert Advice for a Perfect Fit
The “Pro Checklist”: What to Bring in
To help us provide the most accurate estimate, it helps to have a few details ready. If you aren’t sure, don’t worry – we can help you navigate these options during your consultation:
Dimensions & Application: Are we looking at a rough opening for new construction or a “pocket” replacement for an existing frame?
Glass Thickness & Panes: Do you need standard double-pane for insulation, or triple-pane for maximum soundproofing and thermal retention?
Energy Coatings (Low-E): Ask us about Low-E coatings like SunCoatMAX to block UV rays and keep heat inside during winter.
Tempered vs. Annealed: We’ll guide you on where safety (tempered) glass is required by local Bozeman building codes.
