The BlackFramed Buyer's Guide
Everything to know before investing in custom steel windows.
Buying custom steel windows isn't simply choosing glass — it's choosing how light, air, and view move through your home. This guide walks through the decisions that matter most, before you request a quote.
The right windows flood a room with natural light, frame a view, and improve comfort and efficiency for decades. The wrong ones lead to drafts, glare, and expensive compromises. Here's what to consider before you order.
Start With The Window Type
Every elevation deserves a different solution.
The first decision isn't the style — it's how the window should function. Different window types create different light, ventilation, and views.
Fixed Windows
Fixed / Picture Windows
Uninterrupted glass for maximum light and framed views, with no moving parts.
- Statement walls
- Living rooms
- Stairwells
- Tall openings
Casement
Casement Windows
Hinged at the side and cranked open for full ventilation and a tight seal.
- Kitchens
- Bathrooms
- Hard-to-reach openings
Awning
Awning Windows
Hinged at the top and opened outward, allowing airflow even in the rain.
- Basements
- Above counters
- Combination walls
Sliding
Sliding Windows
Horizontal panes glide side to side — a low-profile option for wide openings.
- Bedrooms
- Hallways
- Wide horizontal openings
Bay / Bow
Bay & Bow Windows
Multiple panes project outward to add depth, light, and interior square footage.
- Dining nooks
- Primary suites
- Street-facing façades
Choose The Right Profile System
The steel behind every window matters.
Not every steel window is built the same. The profile system determines sightlines, strength, thermal performance, hardware compatibility, and longevity. BlackFramed works with original European profile systems trusted by architects around the world.
Ottostumm W40
Thermally broken system with remarkably slim sightlines.
- Luxury residential projects
- Exterior windows
Ottostumm W50-TB
Heritage-profile thermal break system with the deepest sightlines of the range.
- Historic & estate architecture
- Statement windows
- Cold-climate performance
Welser
Excellent value for temperate climates where thermal performance is less critical.
- California
- Mild climates
- Commercial interiors
Consider Your Climate
Not every window needs a thermal break.
Southern California & similar
A non-thermal profile may be perfectly appropriate for many window applications.
Colder regions, code-driven projects
A thermally broken system dramatically improves insulation and comfort where energy codes require it.
Our specialists will recommend the appropriate profile system based on your location, application, and performance goals.
Think Beyond Black
Choose a finish that complements your architecture.
While matte black remains timeless, every BlackFramed window can be finished in virtually any RAL color.
Every finish is professionally applied using premium European powder coating systems for exceptional durability.
Choose Your Glass
Glass affects privacy, daylight, efficiency & security.
Hardware Completes The Experience
The one part of the window you'll touch every day.
