A piece of siding is used as sill extension and to provide slope in the opening for the window, which is deeper because exterior rigid foam has been added
Image
A thin-triple window uses a narrow interior glass pane and narrower gaps between panels often filled with krypton, rather than argon gas, to achieve triple-pane performance with an IGU that fits in a double-pane window frame
Image
Accordion-type hurricane shutters protect sliding glass doors from high winds and wind-borne debris.
Image
Image
An interior shade that closes from the bottom up can work in conjunction with an exterior overhang to block lower-angle sunlight while still allowing view through the upper portion of the window that is shaded by the overhang.

ENERGY STAR Certification Criteria for Residential Windows, Doors, and Skylights, Version 7.0, effective 10-23-23
Image
Even with R-30 of insulation in the wall, its overall R-value is R-5 if it has single-pane windows; triple-pane windows bring that up to R-16
Image
Exterior shading devices such as these Bahama shutters can significantly increase the hours of safety provided by a home during an extreme heat event.
Image
Failure of Roof Structure from Pressurization Due to Window Failure During a Hurricane.
Image
Hurricane force winds that breach external windows and doors can then cause failure of the entire building due to internal pressures on walls and roof.
Image
Hurricane shutter styles include colonial, Bahama, roll-up, and accordion shutters.
Image
In a comparison of two homes that were identical except for windows, the home with thin-triple-pane windows showed averaged winter heating savings of 12% annually, average cooling season savings of 28%, and peak savings of 17% to 33% compared to the home
Image
In areas prone to high winds and hurricanes, double vertical “jack trim” and horizontal “header” and “sill” studs are recommended on all sides of window and door openings.
Image
Image
Low-E storm windows are a cost-effective retrofit that is easy to install and can cut heating and cooling bills 10% to 33%.
Image
Replacing double-pane windows with triple-pane windows can significantly reduce winter-time condensation by warming the interior surface of the windows

The NFRC/ENERGY STAR label provides consumers with several performance ratings for a window
Image
The unprotected glazing in this door was broken by roof tiles dislodged by wind.
Image
To get an average whole-wall R value of R-19 with double-pane windows, you’d need R-330 of wall insulation; triple-pane windows can achieve an R-19 total wall R Value with R-38 of insulation
Image
Triple-Pane windows can be used as a tradeoff for continuous wall insulation or stricter air sealing targets when showing compliance with the 2021 IECC using the UA path
Image
Triple-pane windows use three panes of glass separated by gaps filled with krypton or argon gas, insulated spacers, and low-emissivity coatings to achieve high insulation performance
Image
Types of window attachments include exterior attachments such as storm windows, fixed awnings, dynamic awnings, roller shutters, roller shades, and solar screens, and interior attachments such as drapes, louvered blinds, roller shades, surface applied fil
Image
View-preserving interior solar screens such as these help reduce glare and solar heat gain while maintaining view to the outside
