Standard Curb-Mounted Skylight
Baseline curb-mounted skylight configuration for common projects where availability, cost, and straightforward installation matter.
Skylights installed over raised curbs for flexible roof conditions and low-slope applications. Selection should start with the opening condition, exposure, performance target, code requirements, manufacturer limits, installation details, and the documents needed for pricing or submittal review.
Configurations
How It Comes
Applications
Where It's Used
Residential Projects
Curb-Mounted Skylight products may be used in residential work when the configuration, finish, maintenance expectations, and performance ratings match the opening.
Commercial Projects
Commercial applications should verify traffic level, code requirements, tested assemblies, submittal documents, and serviceability.
Replacement and Retrofit
Retrofit work should confirm existing dimensions, substrate condition, surrounding finishes, and whether the product can be serviced after installation.
Custom or High-Exposure Conditions
Large sizes, severe weather, unusual geometry, coastal exposure, fire ratings, or acoustic goals usually require early manufacturer review.

Frame / Glazing System
Aluminum Clad Frame Curb-Mounted Skylight
Aluminum exterior cladding protects roof-exposed skylight frames from weather and UV.
Advantages
- Durable roof exposure
- Low exterior maintenance
- Flashing kit compatibility
Considerations
- Thermal detailing matters
- Finish scratches need attention
- Can conduct heat at weak points
Frame / Glazing System
Wood Interior Frame Curb-Mounted Skylight
Wood interiors provide a warm finished surface around roof windows and many deck-mounted skylights.
Advantages
- Warm interior finish
- Paintable or stainable
- Good insulation value
Considerations
- Needs condensation control
- Must stay dry
- Interior finish can degrade in humid rooms
Frame / Glazing System
Vinyl / PVC Frame Curb-Mounted Skylight
Vinyl and PVC resist moisture in humid rooms, tubular devices, and some curb-mounted skylight products.
Advantages
- Moisture resistant
- Low maintenance
- Good thermal isolation
Considerations
- Limited finish options
- Movement with heat exposure
- Profile choices vary
Frame / Glazing System
Fiberglass / Composite Frame Curb-Mounted Skylight
Fiberglass and composite frames add dimensional stability and weather durability for roof glazing assemblies.
Advantages
- Stable in temperature swings
- Low maintenance
- Good strength
Considerations
- Premium cost
- Fewer product lines
- Longer lead times

Details To Confirm Early
01
Match flashing to roof conditions
Roof pitch, roofing type, curb height, and underlayment sequence drive the flashing kit and installation method.
02
Insulate and air seal the shaft
Poorly insulated light wells create condensation, heat loss, and comfort problems even when the skylight performs well.
03
Plan controls and access
High roof glazing may need shades, rain sensors, cleaning access, and service planning before finishes are installed.
Product Questions
Common Questions
What should I compare first when selecting curb-mounted skylight?
Start with the opening condition and required function, then compare tested performance, size limits, materials, hardware, installation details, and warranty terms.
Can curb-mounted skylight be used in any opening?
No. Size, exposure, code requirements, structural support, hardware compatibility, and manufacturer limits determine whether it is appropriate.
What should be confirmed before ordering?
Confirm final dimensions, handing or operation, finish, glass or material makeup, accessories, installation method, lead time, and required submittal or test documentation.
