All Weather

All Weather

Service: All Weather Architectural Aluminum was founded in 1969 and remains a family owned and operated commercial window and door manufacturer. Mr. Hank Porter founded All Weather Architectural Aluminum and from the beginning the Porter family emphasized manufacturing quality products and providing superior customer service. For over forty years the ability to create special solutions for difficult projects has always been All Weather’s primary strength.


One aspect to commitment in quality can be found in the equipment we invest in. We operate from two plants located next to each other. Plant #1 measures 52,000 square feet and houses the glass cutting equipment, glass fabrication equipment and a tempering furnace. We process the glass used in our window and door products. This often times allows us quicker lead times and a higher standard of quality for the insulated and tempered glass we provide in our windows and doors. Plant #2 measures 77,000 square feet and is where we manufacture the windows and doors themselves. We are able to roll our strut material together and provide precision pre-fabrication prep with our machinery. Having the machinery to keep these processes in house allows us to control the quality in the product we sell. We continue to invest in quality machinery with this in mind.


Quality surrounds us in our working environment. All Weather currently resides in a state of the art facility in Vacaville, California. We understand the energy and “green” commitment involved during the building process. Lance Porter built our current building with natural day lighting and ventilation throughout, a unique night sky cooling systems to minimize our energy usage, and an overall aesthetically spectacular work environment. At times during the year, we modify our manufacturing schedules to reduce energy consumption and partner with local power providers in their programs. It is a one of a kind manufacturing plant in its design and layout. We believe in creating a quality product, which stems from operating from one.


The number one ingredient to providing you with a quality product is our personnel. We are driven and motivated to providing excellent customer service. Our outside and inside sales teams have resources at their fingertips to provide you with the information about our products and/or your quote/order. We have 2 engineers on staff constantly thinking of what’s next. Our manufacturing crew pays close attention to detail. Our drivers are professional and courteous and will become a familiar face on multiple deliveries. From order to delivery, your interactions with All Weather will be professional and friendly.


The series 3000 and 5000 are two examples of our mnay product lines.

The Series 3000 projected window is All Weather’s most versatile window system. The 45 degree mitered and welded corners provide weather-tight corners that are both strong and aesthetically pleasing. Two rows of weather-stripping are used to ensure low air-infiltration and prevent weather penetration. With options including arch-tops, corner windows, true divided lights, and an integral recessed panning frame, the Series 3000 has the design capabilities to make your building stand out. Our series 3000 1 5/8” product line uses 6063 extruded aluminum and are age hardened to a T-6 rating for strength and durability. The series 3000 windows have integral extrusion walls with a nominal web thickness of .125” , and a wall thickness of .094”. The nailing fins will be .050” thick. The material thickness on all wall sections meets or exceeds commercial window standards.

The Series 5000 projected window is All Weather’s most affordable thermally broken product line. Utilizing a pour and de-bridge thermal break, this series provides a cost-effective way to get a thermally efficient glazing product without sacrificing performance or aesthetics. With nail-on, equal leg, comp. channel, and integral recessed panning frame options, this window series has the options to make installation of this product efficient, attractive, and weather-tight. Our Series 5000 2 1/4” product line uses 6063 extruded aluminum and are age hardened to a T-6 rating for strength and durability. The Series 5000 windows have integral extrusion walls with a nominal web thickness of .125” and a wall thickness of .094”. The nailing fins are .062” thick. The material thickness on all wall sections meets or exceeds commercial window standards. The pour and debridge thermal break profiles are extruded as a single extrusion with a cavity for the thermal break material. Once the profile is extruded, the cavity is filled with a two part polyurethane that has a low coefficient of thermal conductivity. After the polyurethane has cured, a saw is used to debridge the profile by ripping the aluminum web of the cavity. The profile is now thermally broken providing both improved condensation resistance as well as improved thermal performance.

Milgard Windows

Milgard Windows and Doors - Associated Building Supply

About Us: At Milgard we have one unwavering goal, and that's to be the best window and door manufacturer. We will settle for nothing less. To achieve that goal, we are committed to three guiding principles: (1) The individual must be respected (2)The customer must be given the best possible service (3) Excellence and superior performance must be pursued.

Employees Are the Key to Our Success. Milgard's history of growth and success as a window and door manufacturer is due to the dedication of our employees. To be the best, we hire the best. More than 3,000 Milgard employees work hard every day to give our customers high-quality products and superior service. They're a big part of the answer to the question: Why Milgard? Fifty Years of Innovation in Window and Door Manufacturing. In 1958, Maurice Milgard, Jr. and his son Gary started Milgard Glass Company in a small building in Tacoma, Washington. Gary's brother, Jim, joined the company in 1961. Within a short time, the Milgards diversified into aluminum windows.

In 1962, Gary Milgard left the glass company to start an aluminum window fabricating company called Milgard Manufacturing. The company's objective was to provide a reliable source of quality aluminum windows styled and crafted to meet the unique architectural requirements of the western United States. In 1968, Milgard Manufacturing started producing sliding glass doors. Two years later, aluminum frames were redesigned to fit both single-pane and insulating glass. Milgard developed a type of aluminum frame that was suitable for cold weather areas where only wood frames had been effective. The year 1989 marked the introduction of the first Milgard® windows with vinyl frames. WoodClad™ windows and doors, a dramatic new line of fiberglass windows and doors, was introduced in 1990. Growth continues to be the norm at Milgard. In addition to the Tacoma operation, the company now has manufacturing, sales and service locations in Portland, Oregon; Las Vegas, Nevada; Sacramento, Hollister, Simi Valley, Temecula and Dixon, California; Denver, Colorado; Salt Lake City, Utah; Phoenix, Arizona, and Dallas/Fort Worth, Texas.

The Vertically Integrated Windows Manufacturer: While many window companies are simply distributors of someone else's products, Milgard is a vertically integrated window and patio door manufacturer. We make our own insulated glass units. We produce our own vinyl components. We make our own fiberglass frames. The Milgard vinyl plant, located in Tacoma, began extruding quality frame material in 1988. To ensure top quality from start to finish, Milgard begins by precisely controlling our vinyl compound formulation to withstand harsh climate conditions. We extrude our own frame material, and fabricate all vinyl windows and doors to order, giving us the tightest control over quality. Our fiberglass windows and doors receive the same level of attention. Almost all our frame materials are manufactured internally to provide the highest level of consistently high quality.

Milgard also goes so far to temper our own glass. In 1980, Milgard Tempering, Inc. was started in Tacoma to respond to a demand for high-quality tempered glass in the Northwest. In 1992, a second Milgard Tempering plant was opened in Dixon, California. Modern equipment and skilled employees enabled Milgard Tempering to become one of the most respected tempered glass suppliers in the country.

Through our vertical integration, Milgard is able to control quality at every step of the way. The result is higher quality products, all of which we confidently back with one of the industry's best guarantees, Milgard's Full Lifetime Warranty.
