Insulated Back Pans
Back pans are one of the most common support RFQs in opaque and spandrel zones because they combine closure, insulation, and coordination into one fabricated part.
Specialist support
Adjacent support parts that keep glazing and curtain-wall packages moving.
CMF fabricates the light-gauge support components facade teams need around the opening without overstating full system scope.
Support lane only. This page is for adjacent fabricated parts, not full curtain-wall system supply or field installation.

Frequent parts
Common glazing-support parts sent out for pricing
Facade teams usually RFQ these adjacent components when they need closure, opaque-zone backing, and perimeter coordination around the opening.
Interior Closure Panels
Interior closure panels help close off exposed structure cleanly behind curtain-wall or storefront openings.
Shadow-Box Panels
Shadow-box components show up where the facade design wants depth behind glass while still relying on brake-formed support parts and coordinated finishes.
Sill Closure And Flashing Pieces
Sill conditions are often quoted on their own because they sit at a high-risk water interface and usually require drawing-specific geometry.
Head And Jamb Closures
Head and jamb pieces are common RFQ items wherever facade teams need formed parts to finish perimeter conditions around glazing frames.
Perimeter Trims And Slab-Edge Closures
These support parts get purchased when the hidden interface around the opening needs a clean, buildable closure rather than a broad system redesign.

Commercial package snapshot
Before you send support details
Scope limits, acceptable inputs, and release handling are usually what decide whether a support package moves forward.
The main questions are what fits here and where the scope stops.
- Support scope
- Back pans, closure pieces, slab-edge trims, shadow-box parts, and adjacent fabricated support components
- Material and finish context
- Material, coating, and corrosion decisions stay visible because these parts often sit near exposed or weather-sensitive conditions
Most support packages start from partial coordination material, not a perfectly separated release.
- Enough to quote
- Details, section cuts, model views, and marked-up interface notes are useful when the support geometry is identifiable
- Coordination style
- The review stays focused on the adjacent fabricated part and its interfaces instead of drifting into full curtain-wall system scope
Once the scope fits, the next question is how the support package will move through the project cleanly.
- Quote speed
- Commercial quote response within 24 hours
- Package handling
- Support parts can be grouped by opening, zone, or release sequence so the field team gets the right adjacent components at the right stage
This page is built for adjacent support parts, not a full-system substitution.
Project fit
What qualifies as glazing support work for CMF
This lane works best when the adjacent fabricated part is clear and the scope stays intentionally narrow.
Best fit for CMF
- Back pans, closure panels, slab-edge trims, shadow-box pieces, and adjacent support parts around glazing systems.
- Partial details, section cuts, model views, or marked-up screenshots where the interface geometry is clear enough to review.
- Narrow, component-led scopes that need fabrication support without turning the page into a full curtain-wall supply claim.
Usually out of scope
- Full curtain-wall or storefront system supply, substitution, or redesign requests.
- Glazing installation, field labor, or broad facade contracting responsibilities.
- Packages where the support part is not yet identifiable from the drawings or coordination material.

Existing quote flow
Share support details or drawings for a quote
Send drawings, markups, model views, or project details through the standard quote form. CMF will review the request around adjacent fabricated support parts rather than broad system supply.
- Support details, markups, and adjacent-part drawings are enough to start.
- The scope stays on support components rather than full curtain-wall supply.
- Narrower scope keeps the request clear.

Project FAQ
Glazing / Curtain-Wall Support FAQ
These are the usual scope and coordination questions before support details go out for pricing.
Do you supply full curtain-wall or storefront systems?
No. CMF quotes adjacent fabricated support components such as back pans, closures, trims, and other light-gauge parts that fit into a broader facade package.
Can I send support details before the full facade package is finalized?
Yes. Partial details, marked-up sections, and model views are useful when the support geometry is identifiable. You do not need to wait for a final released package to start the conversation.
Do you quote back pans and closure pieces as standalone package work?
Yes. Those parts are often broken out as their own quote package because they solve a specific interface condition without needing a broader system supplier claim.
Can model views or coordination screenshots help if dimensioned drawings are incomplete?
Yes, as long as they make the adjacent condition and intended fabricated part clear. CMF can use that context to identify what additional dimensions or notes are needed for a clean quote.
Do you install glazing or provide field labor?
No. CMF stays on fabrication and delivery support, not site installation or glazing labor. The goal is to deliver the adjacent fabricated parts the facade team needs to finish the package.
