Window Replacement: Unrealized Benefits

June 23rd, 2017|

Most U.S. buildings currently in use will continue to be until 2050 and, eventually, will require renovation. Helping building and property managers evaluate and maximize the benefits of window system renovation and upgrades, Apogee Enterprises, Inc.’s Building Retrofit Strategy Team offers a new 28-page publication.

“Replacing aging windows with new, high-performance systems provide a better environment for the building’s occupants and greater value for the building owner,” says John Bendt, vice president of Apogee’s Building Retrofit Strategy Team.

“Window systems and components have evolved significantly since the 1980s,” explains Kevin Robbins, Apogee’s Building Retrofit Strategy Team account manager. “About half of all U.S. commercial and institutional buildings were constructed prior to this period, which presents a significant opportunity for owners and occupants to benefit from façade improvements and window replacement.”

Bendt continues, “Among the many benefits, modern window systems improve the appearance and performance of aging buildings. New, high-performance glass and aluminum frames with thermal barriers help save energy, reduce maintenance, lower vacancy rates, increase rental rates, provide a better environment for the building’s occupants and creates greater value for the building owner and enhance occupants’ satisfaction and comfort.”

Describing these benefits and best practices in achieving them, the paper shares nine case studies [ Read More… ]

Shared Learnings: It’s That Time of Year

August 22nd, 2013|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc.

Summer sets as the autumn tradeshow season dawns. GlassBuild America, Sept. 10-12 in Atlanta, and CSI Construct, Sept. 25-27 in Nashville, bring that bittersweet reminder that we have entered the third quarter. This year’s expos are expected to showcase new fenestration products to meet commercial buildings’ increasingly stringent performance and code requirements.

Last October, Hurricane Sandy proved to be the second-costliest hurricane in U.S. history with damages estimated at $68 billion. The 2013 hurricane season already has produced four named storms. Entering into the peak of the season, National Oceanic and Atmospheric Administration (NOAA) issued an update in August predicting a 70% chance of seeing above-average activity in the Atlantic with potentially 13-19 named storms, six to nine hurricanes, and three to five of those hurricanes becoming major events.

Hurricane impact-resistant fenestration products help address commercial building owners’ concerns for mitigating damage to their property and protecting occupants from shattered glass and wind-borne debris. A breadth of storefront and entrance systems are available to comply with High-Velocity Hurricane Zone (HVHZ) wind zones, as well as Miami-Dade and Florida [ Read More… ]

Shared Learnings: The NFRC Non-Residential Program

June 26th, 2013|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc.

For the past 20 years, the National Fenestration Rating Council (NFRC) has provided a fair, accurate, and credible rating and labeling system for windows, doors, and skylights used in residential construction. Anyone who has shopped for a residential window has seen a label similar to the one below:

ES_NFRC_LabelRatings on the NFRC label have been achieved through standardized test methods at independently operated laboratories. This standardized method allows you to fairly compare window performance of “Manufacturer A” to “Manufacturer B.”

The NFRC testing protocols involve testing of the full window — including glass, frame, spacers, and any other component that is a permanent part of the complete product. This strategy provides a more accurate reflection of how the product will perform in the home than testing of just glass, as the framing and other components influence ratings such as U-Factor, Solar Heat Gain Coefficient (SHGC) and Visible Transmittance (VT).

In commercial storefront and curtainwall glazing systems, glazing contractors combine various components that have not been tested as a complete product. For instance, storefront or curtainwall from one manufacturer; glass, coatings and infill [ Read More… ]

Aluminum Finishing – PVDF Coatings (Part 2 of 2)

May 15th, 2013|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc.

Know the Code

When specifying a paint code for your project, always double check for accuracy. The specific code is what drives the ordering process and the achieved color. The color name is only a guideline; many times manufacturers and applicators will have the same paint name for different paint types and colors. Relying on a color name alone can be a risk. As an example, one manufacturer can have 50 paint codes all named “Hartford Green.”

Coated aluminum panels have been tested for performance in the high-salt, high-humidity, and high-UV exposure environment of South Florida. Image courtesy of Linetec.

Accuracy of the paint code is vital. Paint manufacturer and many applicators have their own coding system for assigning paint codes to colors. Each letter and number within the product formula has a specific meaning related to the color and tint, gloss, primer, topcoat, or the use of mica and metallics. Due to the immeasurable number of different paint [ Read More… ]

Aluminum Finishing – PVDF Coatings (Part 1 of 2)

April 17th, 2013|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc.

Fluoropolymer coatings are two-coat systems formulated to provide excellent performance against weathering in normal environments. Suited for architectural product applications — such as storefronts, curtainwalls, windows and louvers — these coatings are highly resistant to chalking, chipping, peeling and fading. They also protect against chemical staining and environmental stresses such as dirt, ultraviolet (UV) radiation and acid rain. The coatings are available in a wide range of earth tone colors and offer excellent color consistency.

“XL” coatings are three- and four-coat systems consisting of a primer, a fluoropolymer color coat, a clear topcoat and sometimes a barrier coat to seal and protect the entire system. A clear top coat is required for one of two reasons, to protect and encapsulate the metallic flake in the topcoat, or to give added UV protection to bright and exotic colors.

These coatings offer the perfect solution for projects such as chlorine rooms, sewage treatment facilities, power plants, paper mills and highly aggressive environments including industrial and seacoast areas where maximum protection against chemical and salt spray corrosion is required.

Please note that paint manufacturers do not recommended using a clear topcoat over a white [ Read More… ]

Shared Learnings: What is Anodizing? (Part 2 of 2)

March 20th, 2013|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc.

Specifying Anodized Finishes

The Aluminum Association has developed a system of designation for anodized finishes on aluminum. Specific finishes of the various types are designated by a letter followed by a two-digit numeral. Each designation may be combined into a single composite designation to identify a sequence of operations covering all of the important steps leading to a final complex finish.


Almost all finishes used on aluminum may be subdivided into three major categories: mechanical finishes, chemical finishes and coatings.

Descriptions of the most commonly utilized finishes are as follows:

* Mechanical: (M)
M10 – Unspecified as fabricated

* Chemical (C)
C21- Fine matte (eco-friendly etch process)
C22 – Medium matte etch (caustic etch process)

* Anodic Coatings (A)
Architectural Class II (0.4-0.7 mils thick)
A31 – Clear
A32 – Integral Color
A34 – Electrolytically deposited color (two-step)

Architectural Class I (0.7 mil and thicker anodic coating)
A41 – Clear
A44 – Electrolytically deposited color (two-step)

All composite designations are preceded by the letters “AA” to identify them as an Aluminum Association designation.

* Example 1: Aluminum Association (plus) Mechanical Finish (plus) Chemical Etching (plus) Anodic Coating translates to:
Class II Clear Anodized Finish AA‑M10‑C21‑A31 complying with AAMA 611

Shared Learnings: What is Anodizing? (Part 1 of 2)

March 5th, 2013|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc.

What is Anodizing?

Anodizing is an electrochemical process that converts aluminum’s metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. It is readily available for storefront, curtainwall, entrances and daylight control systems.

Exposed to the earth’s atmosphere, aluminum combines with oxygen to form a protective surface film, which inhibits further oxidation of the aluminum. This natural oxide is extremely thin, loosely adhered to the aluminum surface and easily removed by handling. Anodizing is a process, which thickens the natural oxide film resulting in a heavy aluminum oxide film of controlled thickness having the hardness similar to that of a ruby or sapphire. Anodizing is, therefore, a matter of highly controlled oxidation—the enhancement of a naturally occurring phenomenon.

Anodizing uses the base metal – the aluminum alloy – to create a thin, extremely strong and corrosion-resistant finish. The anodized surface is very hard and thus preserves and extends the life of the aluminum product. Architectural aluminum anodic coatings provide good stability to ultraviolet (UV) rays and does not chip or peel.

The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. This aluminum oxide is not [ Read More… ]

International Green Construction Code & Building Design

October 18th, 2012|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc.

The International Green Construction Code (IgCC) is the first national green model code. It is flexible, enabling jurisdictions to choose additional requirements that make the code a deeper shade of green, while paying close attention to the local climate and local regulatory requirements.

This new code is intended to provide “minimum requirements to safeguard the environment, public health, safety and general welfare;” to reduce the negative impacts and to increase positive impacts of the built environment on the natural environment and building occupants. As such, it covers natural resources, material water and energy conservation, operations and maintenance for new and existing buildings, building sites, building materials and building components (including equipment and systems). The IgCC applies to all occupancy-types, except low-rise residential buildings under the International Residential Code.

The IgCC can have a major, immediate impact. According to the Energy Information Administration, buildings generate almost 40 percent of all greenhouse gas emissions and 76 percent of all power plant generated electricity. Buildings can, and should, be designed to operate with significantly less than today’s average energy levels.

How does this complement existing rating systems or other guidelines?

Shared Learnings: Shedding Light on Photovoltaics

September 19th, 2012|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc.

Photovoltaics convert light energy into electrical energy. The word “photovoltaic” is derived from photo, the Greek word for light, and volt, relating to electricity pioneer Alessandro Volta.

In 1954, Bell Labs in the U.S. introduced the first solar photovoltaic (PV) device that produced a useful amount of electricity, and by the late 1950s solar cells were being used in small-scale scientific and commercial applications, especially for the U.S. space program.

The International Space Station relies on PVs for its electrical needs.
Photo Courtesy NASA.
The Mars Rover is powered by photovoltaics. PVs work on other planets!

When PVs were first introduced into the marketplace back in the late 1970s they were very expensive, not very efficient and not for the average residential or commercial construction project. In recent years, PVs have seen a huge surge in popularity and integration into building designs. The cost per “peak watt” continues to decline as the efficiency of solar cells continues to improve and more firms are manufacturing PV panels. We’ve seen a new industry of local solar companies sprout up to meet the demand for design and installation services.

LEED® Guidelines and Fenestration Design – Part 2

August 22nd, 2012|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc.

In the second half of this two-part blog, we continue our look at how “smart” fenestration designs and applications can significantly improve a building’s performance using the guidelines in the LEED® Rating System. This month we’ll take a look at Thermal Comfort, Daylighting and Views to the Outdoors.

Materials and Resources Credit 5: Regional Materials

Intent: To increase demand for building materials and products that are extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing the environmental impacts resulting from transportation.

Strategy: Use building materials or products that have been extracted, harvested or recovered, as well as manufactured, within 500 miles of the project site for a minimum of 10% or 20%, based on cost, of the total materials value.

Note: Aluminum is manufactured from mined (extracted) bauxite. There are no bauxite mines in the United States. Therefore, regardless of where the manufacturer is located, aluminum framing systems do not qualify for this credit. LEED version 4.0, due out next year, will require manufacturers and their raw material suppliers to meet disclosure and responsible sourcing requirements.

LEED® Guidelines and Fenestration Design – Part 1

July 25th, 2012|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc.

Not every building is designed to achieve LEED® certification, but using the guidelines in the LEED Rating System can help lower utility costs, minimize the impact on our environment and improve occupant comfort levels. In this two-part blog, we’ll take a look at how “smart” fenestration designs and applications can significantly improve a building’s performance. Part one focuses on Energy & Atmosphere, Materials & Resources and Indoor Environmental Quality.

Energy & Atmosphere Credit 1: Optimize Energy Performance

Intent: To achieve increasing levels of energy performance to reduce environmental and economic impacts associated with excessive energy use.

* Design the building envelope and systems to maximize energy performance. Utilize aluminum and glass manufacturers’ most energy efficient products.
* Determine required minimum total system U-Factor based on aluminum framing system and glass type. Reference National Fenestration Rating Council (NFRC) 100-2010: “Procedure for Determining Fenestration Product U-Factors.”
* Determine required maximum Solar Heat Gain Coefficient (SHGC). Reference NFRC 200-2010: “Procedure for Determining Fenestration Product Solar Heat Gain Coefficient and Visible Transmittance at Normal Incidence.”

Shared Learnings: Controlling Storefront and Curtainwall Water Infiltration

June 27th, 2012|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc.

Most architectural aluminum glazing systems are not designed to be totally waterproof. Rather, most systems are designed to control water infiltration under extreme conditions and weep that water back to the exterior. Storefront and curtainwall systems differ in many ways: appearance, profiles, wind load resistance, glazing, thermal performance and how they weep water. This discussion focuses on how storefront and curtainwall handle water disbursement differently.


Storefront systems control water infiltration by directing all moisture to the sill flashing (1). It is imperative that the sill flashing be installed correctly. Most aluminum manufacturers have introduced high-performance sill flashing designs that allow the installer to fasten the flashing to the bottom of the opening prior to installing the storefront framing. A watertight seal can then be applied over the fastener head (2). The sill then sets on top of the flashing with no need for fasteners penetrating the sill flashing. Unlike the old sill flashing designs, these high-performance sill flashings utilize two weep holes in the sill flashing at each lite of glass (3). These extrusions also have a much higher back leg for better water performance, and it is important [ Read More… ]

Shared Learnings: AIA 2012 Preview

May 17th, 2012|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc. As the

American Institute of Architects (AIA) 2012 National Convention and Design Exposition opens in Washington, D.C., exhibitors will be showcasing new technology and products for use in the glass and glazing industry. One focal point will be increasing the thermal performance of commercial glazing systems. This has become paramount as new energy codes continue to be adopted and enforced. Here are some highlights from the exhibit floor.


Triple Glazing

Viracon, and other glass fabricators, offer triple-glazed units that minimize heat transfer improving overall thermal performance. However, while a third pane of glass adds to the insulating value of the assembly, it also reduces the visible light transmission (VT) and the solar heat gain coefficient (SHGC). Adding a low-E coating to a surface, or multiple surfaces, of the triple-pane unit will also increase the energy performance, but it may (depending on the type of low-E coating) affect the SHGC and VT. Filling the space between the panes of glass with argon and/or krypton gas will also improve energy performance.

A third pane of glass increases the weight and thickness of the unit, which can make mounting and handling more difficult and [ Read More… ]

Shared Learnings: Glazing and Energy Codes

April 18th, 2012|

by Tom Minnon, LEED® AP, CDT, Eastern Region Sales Manager for Tubelite Inc.

Architects and building owners face growing challenges in balancing aesthetics and daylighting design needs with increasingly stringent building and energy code requirements. This month’s discussion will focus on ways to reduce heat loss and heat gain to comply with commercial energy codes. Thermal energy performance of glass can be improved several ways; many of them are just now beginning to be incorporated into the commercial segment.


Warm Edge Technology
(Conductive heat loss)

Several products have been introduced that will help reduce conductive heat loss through the edge of insulating glazing units (IGUs). Warm Edge technology will also help reduce condensation that typically occurs around the edge of glass near the frame. Below are some of the different types of IG spacers available.

1. Metal spacers
Made from stainless steel or aluminum. Dessicant consists of tiny beads which absorb any moisture trapped in the unit during manufacturing. Stainless steel offers better performance than steel.

2. Hybrid spacers
Changing metal spacers from a tube to a U-shaped channel reduces the flow of heat through the spacer.

3. Thermal break spacers
Thermal barrier technology creates a warm-edge IGU that reduces thermal conductivity.

4. Foam & Thermoplastic spacers
Non-metal spacers include a foam [
