Shared Learnings: Thermal Barriers

March 21st, 2012|

Aluminum remains the framing material of choice for architectural fenestration products used in non-residential applications. Aluminum has many excellent qualities from recyclability to engineering versatility to corrosion resistance. It also is an excellent conductor of temperature.

Adding a barrier or “break” to insulate between the inside and outside aluminum surfaces, reduces the transfer of hot and cold temperatures. This minimizes the potential for interior condensation and frost build-up in cold weather and helps save energy.

The most common types of thermal breaks used in aluminum-framed fenestration products are:

* Slot thermal breaks remove 1-inch-wide by 6-inch-long sections of aluminum extrusion with only one inch between these slots. This typically is reserved for vertical framing members. Slotted horizontals are typically not strong enough to handle the dead load of glass.

* Clip thermal breaks use a small, plastic “clothespin” clip to separate the interior and exterior aluminum surfaces.

* Strut thermal barrier systems insert thin fiberglass reinforced “struts” into the aluminum extrusion.

* Pour and debridge thermal barriers involve pouring a two-part, chemically-cured resin into a cavity in the extrusion. After it hardens some of the aluminum is cut away creating the break. The pour [ Read More… ]

Shared Learnings: U-Factors

Energy efficiency and occupant comfort are two key criteria in designing green buildings, especially for projects seeking LEED® certification. Contributing to these goals, thermal performance will continue to be an essential factor in the upcoming International Green Construction Code (IgCC) and the 2012 International Energy Conservation Code (IECC), as well as the Architecture 2030 Challenge, which calls for the operation of all new buildings and major renovations to be carbon neutral by 2030.

According to Architecture 2030, the non-residential/or commercial building sector is currently responsible for almost half of the energy – consumption (49%) and green house gas emissions (47%) in the U.S. The greatest percentage of the energy consumption and their associated emissions is attributed to buildings’ operations, such as heating, cooling and lighting.

Windows in these buildings are major contributors to the nation’s gross energy consumption. Energy-efficient building designs must comply with codes and meet owner expectations. Design professionals are concerned with misrepresentation of energy savings. Understanding thermal transmittance in window systems will help to correctly report energy savings.

U-Factor is a measure of:

Shared Learnings: Lessons for a New Year

January 19th, 2012|

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

As we begin 2012, I add blogging to my list of New Year’s resolutions and new skills. In our industry, “What’s new?” is a question we’re constantly asked by architects. Staying current, accessible, relevant and knowledgeable are expectations. These are especially important qualities when discussing sustainable design and environmentally responsible construction.

The challenges, codes and opportunities pertaining to green building will continue to increase in the coming months. For the last several years, sustainability issues have gained momentum and the conversations have gained depth. In my upcoming blogs, I’ll explore considerations and requirements of green attributes in commercial fenestration. Topics are likely to include daylighting, views, natural ventilation, indoor air quality and VOCs, recycled content, maintenance and durability, re-use and restoration, energy-efficiency and thermal performance, as well as specific applications such as in high-security projects or hurricane zones.

For me, the green building conversation and its practical implementation are a way of life. I’ve been working with architectural glazing systems for almost four decades. I earned my Leadership in Energy and Environmental Design (LEED®) professional accreditation when this green building rating system was still on version 1.0.
