Reviewing the Impact-Resistant Sliders and Windows

Bob recaps the visit to the PGT window factory where the impact-resistant windows for the storm-ready house are made and tested. He reviews the violent impact testing they undergo and how they are laminated with DuPont Buticite in between the layers of glass to prevent a puncture or penetration that could lead to total building failure. The heavy slider panels are installed and adjusted to make a solid, secure, and smooth sliding door set.

" Last week we visited the PGT plant not far from here where they make about 30000. Of these impact resistant windows a week. And we saw firsthand how they stand up to objects hurled at them and high winds. Back here we saw how they're installed into the precast openings in our solid wall frame. And we got started installing the frames through some of the pretty large sliders. Once they were set the guys were able to work the enormous glaze panels into their tracks and adjust them for smooth operation. Even though they're heavy they're well balanced well designed sliders. And of course that means that whether they're closed or open. You're gonna enjoy this terrific canal view with all the sailboats and stuff and you're gonna have the the assurance that if you are in a hurricane with high winds you've got the impact resistant glass with the -- site. You thought you site later in the middle of it which means that no matter what them. Shoots into this at a height -- a high impact great it's not gonna shatter the glass and that's the key thing not allowing hurricane winds to enter into the house envelope because that's how everything it's just."

Installing Impact-Resistant Sliding Glass Doors
Installing Impact-Resistant Sliding Glass Doors

Bob joins Scott Renfroe from Great Southern Windows for the installation of nine foot by eight foot sliding patio doors. Like the windows throughout the house, these are WinGuard impact-resistant glass doors from PGT Industries. The door opening, like the window bucks, has a pre-cast concrete lip that will prevent the door from blowing in and give it a firm seat for installation. An installer is laying a bed of mud or concrete mortar on the door sill to make a bed for the door frame. Renfroe explains that this helps set the door and also gives a soft bed to help level it. Once the frame has been set in the wet mortar and adjusted for level, temporary screws are installed in the frame so that Renfroe can check for plumb and begin to shim the gaps. He installs set screws, places the shims, drills through them, checks for plumb, then pre-drills and drives the permanent screws into the concrete walls. The frame will sit for at least a day while the mortar sets up because installing the heavy glass panels would compact the mud and disturb the level.

Storm-Ready Windows and Doors
Storm-Ready Windows and Doors

Doors and windows are vulnerable components of your homes protective shell or envelope because they are easily penetrated by wind-borne debris often generated by the high winds of storms like hurricanes. If that envelope is breached during a storm because of the failure of windows and doors, wind, wind-driven rain and debris can enter your home causing considerable damage to its interior and your property. A more critical issue develops when the envelope is breached -- high winds can enter your home and exert high pressure on your walls and roof. These internal pressures combined with the external pressure of wind blowing over your home can lead to catastrophic damage. You can protect your home's openings by installing impact-resistant windows and doors or installing impact resistant coverings, such as shutters over windows and doors. Impact resistant glass and shutters are specifically designed to meet a combination of impact and continuous pressure from the wind. Always use products that have been tested to one of these standards and have been designated as such through a recognized product approval system or evaluation report. Ratings SBCCI SSTD 12 ASTM E 1886 and ASTM E 1996 Miami-Dade Protocols PA 201, PA 202, and PA 203. Impact resistant windows usually consist of a clear plastic-like film sandwiched between two specially-treated pieces of glass, giving the window greater strength than glass alone. Equally important as the strength of the glass is the strength of the window's frame. An impact resistant window is tested as a unit that includes the glass, the frame, as well as the attachment hardware and the installation method. Impact resistant windows should always be installed following the manufacturer's recommendations. Exterior doors should also be wind and impact resistant or protected with an impact resistant covering. Garage Doors Garage doors are particularly vulnerable to high winds, because of the long span of opening they cover and the relatively lightweight material they are made of. Two options are available for strengthening garage doors. Replace the door and track with a system that is designed to withstand high winds and wind-borne debris. The second option is to protect the garage door with a tested and approved impact resistant covering.

Pella Energy Star Rated Fiberglass Windows and Sliding Glass Patio Doors
Pella Energy Star Rated Fiberglass Windows and Sliding Glass Patio Doors

Once the roof is in place, the windows and sliding patio door in the back can be installed. The windows are from a new fiberglass window line from Pella, which includes low-emissivity glass for greater efficiency. The fiberglass frames make them more resistant to extreme weather. The windows will not warp or rot in the heat or cold. Duane Putz of Pella reviews the features of the windows and glass patio door. The Pella Impervia door is made from Duracast, a fiberglass composite, and is very durable, and resistant to impact and scratches. All of the hardware is color matched to the product so it blends very nicely. It's also available in other finishes such as brass, satin nickel, and bronze. Both the upper and lower sash can be raised or lowered, providing natural ventilation. The sashes tilt inwards making it possible to clean the exterior face of the glass from the interior of the home. Pella Impervia windows are Energy Star rated in all 50 states and save the average homeowner 24 percent over single-pane wood windows. The powder coat finish over the fiberglass means there is no need to add a stain or finish to the window.

Emergency Board Up
Emergency Board Up

If your home is not protected by impact-resistant windows and doors; or impact resistant shutters or panels; consider building your own temporary emergency panels. Step One: Plan the Project. Count and measure each window and door that has glass including French doors, sliding glass doors as well as skylights. You might also want to include roof and gable end vents or any opening that if damaged would allow wind to enter your home. Measure each opening horizontally inside the exterior trim and vertically from the sill to the bottom of the top trim. Add eight inches to both the height and width to provide a four-inch overlap on all sides. When measuring a window with an extended sill measure from the top of the sill to the top of the window and add four inches instead of eight. Sheets of plywood are generally 4 feet by 8 feet. This will help determine how many sheets to buy. Be sure to purchase plywood that is 5/8 inch or greater, exterior grade (CDX). Step Two: Assemble Your Tools and Hardware. You will need a circular saw, drill and drill bits, hammer and wrench, work gloves and safety goggles for this project. You will also need an assortment of hardware including bolts, wood or masonry anchors, nuts and large washers. A range of bolts may be used because different bolts will be needed for wood frame versus masonry homes. Wood Homes use lag screws and plastic coated permanent anchors Masonry Homes use expansion bolts and galvanized permanent expansion anchors Step Three: Get Started Having someone help you with this project will make things a lot easier. First drill holes in the same diameter as the bolts or screws, 2-inches in from the edges of the plywood at each corner and at 12-inch intervals around the panel. Next hold the plywood firmly in place over the opening to mark where to drill mounting holes. If the window sill is flush to the wall, secure the plywood on all four sides. If the window sill extends out at the bottom, secure the plywood on the top and sides. For windows 3 feet by 4 feet or smaller installed on a wood frame house, use 1/4-inch lag screws and plastic coated permanent anchors. The lag screws should penetrate the wall and frame surrounding the window at least 1 3/4 inches. For larger windows, use 3/8-inch lag screws that penetrate the wall and frame surrounding the window at least 2 1/2 inches. For windows 3 feet by 4 feet or smaller installed on a masonry house, use 1/4 inch expansion bolts and galvanized permanent expansion anchors. The expansion bolts should penetrate the wall at least 1 1/2 inches. For larger windows, use 3/8-inch expansion bolts that penetrate the wall at least 1 1/2 inches. If a window or door is larger than a sheet of plywood, you will need to join the panels with 2X4 bracing along the entire seam. Attach the 2X4s to the outside of the plywood panel with 10 gauge, 2 inch long galvanized screws (exterior deck screws) spaced every 4 inches. Use the widest side of the 2X4 to run the length of the entire seam. When youre done, mark each panel with the name of the opening so you will quickly know where to install it when a storm is approaching. Store the panels, washers and nuts together in a location away from the elements. Consider waterproofing the panels with paint or a sealant.
