Go to review questionsWhat counts as an opening
In wind guidance, the exterior envelope includes more than glass. Windows, entry doors, garage doors, skylights, glass block, vents, and other penetrations can affect how wind and rain enter a home.
A project may use impact-rated assemblies, tested protective coverings, or a combination. The right approach depends on the existing opening, design pressures, local code, product approvals, installation details, and the homeowner's goals.
- Windows and glazed doors
- Exterior entry and patio doors
- Garage doors and other large openings
- Skylights, glass block, and other vulnerable openings
What to document before requesting quotes
Create an opening-by-opening inventory and note what is already installed. Photograph labels when readable and gather prior permits, product approvals, plans, or inspection reports.
- Approximate size, material, and operating style
- Existing shutters, panels, impact labels, or unknown conditions
- Observed leakage, damage, difficult operation, or egress needs
- Interior finishes, alarms, screens, and access constraints affected by installation
Compare the complete scope
Two proposals are not comparable when one covers only windows and another includes doors, finishing, permits, disposal, and protection of the work area. Ask each contractor to identify included and excluded openings and the exact product or covering method.
Product approval does not replace correct installation. Confirm who is responsible for measurements, substrate conditions, fastening, flashing or sealant, inspections, closeout documents, and warranty service.
- Opening schedule and product identifiers
- Design-pressure and impact basis
- Permit and inspection responsibility
- Interior/exterior finishing and water-management details
- Warranty owner, exclusions, and service path
Confirm the right product and installation
HomeProject can help you compare the opening schedule, product documents, quote scope, and permit questions. A licensed professional and the responsible building department can then confirm the design and code requirements for your property.
Connect every label to its documents
Terms such as hurricane, storm, or impact should connect to the applicable approval, rating, installation method, and permit documents for the specific opening.
