What others say about fiberglass as a green material

The City of Portland Office of Sustainable Development maintains a "G Rated" website intended to be "the gateway to green building innovation, offering initial consultation and current information specific to individual green projects."

The G/Rated program is designed to speed the adoption of cost effective green building practices as the standard of development in Portland.

On the green building website, the City of Portland Office of Sustainable Development says about fiberglass:

"frames made of fiberglass look like wood but are maintenance free and durable. Fiberglass resists moisture, corrosion and weathering by sunlight, without the need for paint or coatings. It is unaffected by mild acids, salt sprays, will not give off toxic fumes in fires, and will not oxidize. In addition, it holds its shape permanently and will not warp, shrink, dent, sag, or bow."

"Fiberglass has better thermal minimizes heat loss in winter and heat gain in summer."

"Fiberglass has excellent dimensional stability through all types of weather"

LEED and Stromberg Architectural Fiberglass

The internationally accepted benchmark for the design, construction and operation of green buildings is the LEED Green Building rating system. If you're designing towards obtaining the maximum number of LEED credits on your building project, it's important to understand the sections, credits and products that are impacted by materials choices. The following details how Stromberg Architectural Fiberglass can help contribute to qualifying for credits in those sections.

EA 1, 2 - Energy Performance

Intent: To maximize energy performance.


  • EA Prerequisite 2: Minimum Energy Performance. Mandatory. "Design the building envelope, HVAC, lighting, and other systems to maximize energy performance."
  • EA Credit 1: Optimize Energy Performance "Achieve increasing levels of energy performance above the baseline in the prerequisite standard to reduce environmental and economic impacts associated with excessive energy use.

Stromberg: Architectural Fiberglass naturally reduces energy needs of your building project. Architectural fiberglass is a low conductor of heat. The relatively thin fiberglass skin allows designers to maximize the amount of insulation used.

MR 2.1, 2.2 - Construction Waste Management

Intent: To minimize construction debris and divert the debris from construction away from disposal in landfills or incinerators. The goal is to redirect recovered resources back to the manufacturing process and direct reusable materials to the appropriate sites.


Attain at least 50% or 75% (by weight or volume) recycle and/or salvage of non-hazardous construction and demolition debris. Develop and implement a construction waste management plan quantifying material diversion goals.

Stromberg: We address this credit in two ways:

  1. Stromberg is the first and only composite FRP / GFRP manufacturer in the world to offer a closed-loop recycling program which redirects recovered Stromberg GFRP back to the manufacturing process. Stromberg architectural fiberglass composite is 100% recyclable into new products.
  2. For most applications, Stromberg Architectural Fiberglass components and elements are custom molded to size and shape. This minimizes job site cutting and waste.


MR 4.1, 4.2 - Recycled Content

Intent: The goal here is to use products that incorporate recycled materials.


To obtain this credit, use recycled materials so that the sum of post-consumer recycled content plus one-half of the pre-consumer content constitutes 10% or 20% (based on cost) of the total value of the materials in the project. "The value of the recycled content is determined by dividing the weight of the recycled content in the item by the total weight of all materials in the item, then multiplying the resulting percentage by the total value of the item."

Stromberg GFRP : Stromberg architectural fiberglass contains approximately 10% to 50% recycled content. Since Stromberg FRP is an engineered material, recycled content varies depending upon the application.

MR 5.1 and 5.2: Regional Materials

Intent: Promote the use of materials which are extracted, harvested and manufactured locally.


The goal here is to use materials that are sourced: extracted, harvested and manufactured within 500 miles of the project location.

Stromberg GFRP: The regional materials credit may be available to your project depending upon where the raw materials are extracted, harvested and manufactured. This varies depending upon the material selected and which plant our materials are manufactured at. When you provide us project details, we can assist you in determining whether this credit may apply.

7.2 - Heat Island Effect

Intent: Credit 7.2 is designed to "reduce heat islands (thermal gradient differences between developed and undeveloped areas) to minimize impact on microclimate and human and wildlife habitat." The credit is worth one point.


Roofing materials used on low slope roofs with a slope of less than 2:12 need a solar reflectance index (SRI) of 78, while steep-sloped roofs with a slope of more than 2:12 must have an SRI of 29.

Stromberg GFRP: Stromberg architectural fiberglass used for roof structures such as domes, roof panels, spires, cornice and steeples is available in a range of colors with an SRI to meet the needs of your application.

1.1 - Innovation in Design

Intent: Points are awarded for exceptional performance above the requirements set by the LEED Green Building Rating System and/or innovative performance in Green Building categories that are not specifically addressed by LEED.


Identify the intent of the proposed innovation credit, the proposed requirement for compliance, the proposed submittals to demonstrate compliance, and the design approach (strategies) that might be used to meet the requirements.

Stromberg GFRP: Stromberg fiberglass offers unique opportunities for creative applications. We welcome the opportunity to work with you on submitting for innovative design uses.

Other possible areas for LEED contribution include:

ID2.1 Durability:

Stromberg architectural fiberglass is a durable and long lasting material. This reduces the need for replacement, repair and repainting. The durable nature of GFRP makes it earth friendly. Durable products reduce the environmental impact of their production. By doubling the useful lifespan of a product, you halve the environmental impact of its production and construction.

ID2.2 Indoor Moisture Control:

Stromberg Architectural Fiberglass is waterproof and can be part of a system of moisture control.

SSc5 Pest Control:

Fiberglass is unaffected by termites and its use as a replacement for wood reduces or eliminates the need for toxic pesticides. Every year termites and other insects are responsible for over $2.5 billion in damages to U.S. buildings, according to the National Pest Management Association. Using insect resistant materials like architectural fiberglass (GFRP) makes good environmental and economic sense.

5.3.2 Moisture Management:

Stromberg architectural fiberglass is impervious to water and depending upon the application can be part of a system of moisture control.

NAHB Green Building and Architectural Fiberglass

For projects seeking "NAHB Voluntary Model Green Home Building Guidelines" Stromberg Architectural Fiberglass offers:

  • Products that contain fewer resources than traditional products
  • Termite resistant materials
  • No additional finish resources to complete onsite application

What is LEED?

LEED stands for Leadership in Energy and Environmental Design. The LEED Green Building Rating System was developed by the U.S. Green Building Council. LEED is a national voluntary program to define and measure what defines a "green" building. There are a variety of LEED categories, including:

  • LEED for new construction and major renovations (LEED-NC),
  • LEED for existing buildings (LEED-EB),
  • LEED for commercial interiors (LEED-CI),
  • LEED for core and shell development (LEED-CS)
  • LEED for homes (LEED-H).

Under development are new rating systems for neighborhood development (LEED-ND), multiple buildings (LEED-MB), Schools, and Retail. The US Green Building Council (USGBC) is also currently developing application guides for Healthcare facilities and Laboratories.

The goals of the LEED certification process are environmental performance, the improvement of occupant well being, and economic returns of facilities.

LEED Certification

Buildings are LEED certified if they achieve all of the prerequisites and at least 26 points out of a possible total of 69. LEED certification levels are:

* Certified -------------------------- 26 - 32 points
* Silver ----------------------------- 33 - 38 points
* Gold ------------------------------- 39 - 51 points
* Platinum -------------------------- 52 - 69 points

Five environmental categories make up the LEED-NC rating system.

Each of the LEED categories has multiple parts or credits to recognize sustainable building practices. A sixth LEED category recognizes innovative design.

LEED categories are:

  1. Sustainable Sites-----------------------------(14 pts)
  2. Water Efficiency ------------------------------ (5 pts)
  3. Energy and Atmosphere --------------------(17 pts)
  4. Materials and Resources--------------------(13 pts)
  5. Indoor Environmental Quality--------------(15 pts)
  6. Innovation and Design Process------------- (5 pts)
