Proven Technology

I have never seen such reliable, simply attained performance
that is so necessary for high performance in our building,
particularly in trying to meet 2030 Guidelines...

  • Notice how temperature curve does not penetrate fiberglass thermal break.
  • Interior frame temperatures contribute to occupant comfort, useable floor space and building envelope energy efficiency.
  • Fiberglass stops transfer of heat and cold.
  • In high humidity environments, interior frame temperatures play a critical role in alleviating condensation on framing.
  • During cold weather, warm interior frame temperatures help eliminate condensation on the framing

Glazing Infill – 1” Overall IGU, ¼” clear glass, ½” Technoform Spacer, 90% Argon fill, ¼” clear glass with LowE on #3. Center of Glass (COG) U-factor = .247

Simulations are based on Lawrence Berkley Laboratory software THERM 6.3 and WINDOW 6.3.

Finally, a True Thermally Broken Curtain Wall System

ZERO·NET PW2500 Aluminum Curtain Wall

Fiberglass Thermal Break

  • 290 times less conductive than aluminum
  • High strength to weight ratio
  • Low coefficient of thermal expansion is similar to glass
  • Compatible with silicone sealants
  • Mechanically fastened into the framing

Aluminum Framing

  • Modeled after system designs that have been successfully used for years in the glazing industry
  • Back member and face cap completely cover the fiberglass thermal break
  • Framing system looks the same from exterior or interior as traditional systems
  • Creates the structural component of the system
  • Cover caps are easily and affordably customizeable
  • Different depth back members accommodate design pressure and span requirements

Overall assembly U-factor = .30 using insulated glass unit with Center of Glass (COG) = .247

All of the framing components are manufactured and produced in the U.S.A.

Unlike other company’s thermal breaks, which still have exposed aluminum in the glazing pocket, our fiberglass thermal barrier completely isolates interior framing from cold and heat.   Notice how the fiberglass thermal break (in yellow) completely separates the interior framing from anything entering the glazing pocket.


For the ZERO NET curtain wall, aluminum extrusions are used for the back member, cover, and pressure plate. Our extruder uses 37% pre consumer content and 5% post-consumer content for our aluminum extrusions. After the buildings useful life, these extrusions can then be recycled, reducing landfill waste and the mining of raw materials or new products.


The embodied energy required to pultrude fiberglass is significantly less than either aluminum or steel. The main component of fiberglass is sand.  Sand is an abundant non-depleting natural resource – the very definition of sustainable.


Better envelope performance can help in reducing HVAC/ Mechanical requirements.  The reduced energy requirements can also lead to downsizing mechanical/HVAC equipment, making your building even more efficient.


Numerous studies show, managed daylighting in a building has numerous benefits.  It improves occupant comfort and productivity, the views provide mental and visual stimulation increasing a person’s well-being.  To use more glass on a project, you need better thermal performance.  To get better thermal performance, you need a framing system that will work in conjunction with the glass.


Our Industry leading U-factors help reduce annual spend on energy for building heating and cooling costs. Not only does, the owner save money every year, this also positively impacts the amount of greenhouse gases the building produces by reducing the consumption of fuel for heating and cooling.


Pultruded fiberglass has a very long useful life span.  Because of its structure, it is resistant to chemicals, it does not react to other materials and bonds extremely well to silicone sealants.  This all adds up to ensure weather tightness in the framing system and a long life of performance for your building.


Glazing pocket accepts infill from 1” to 1 3/8” which allows you to tailor your glazing options. Whether you are trying to adhere to building codes, meet building energy models, follow daylighting requirements, or create high performance building envelopes we can help you meet your needs.


One does not think a lot about glazing gaskets when it comes to sustainability.  Molded corner gaskets are used at the interior side of the glazing pocket.  This helps ensure ease of installation and improves system weatherability.  Our exceptional numbers for system air infiltration proof this out.    At 6.24 psf the system only allowed .002 CFM/ft2.  This is 30 times better than what is allowed by ASTME 283-12.  Reduce air leakage in a building coincides with better building performance.
