Superior Strength

  • Fiberglass is eight times stronger than vinyl
  • Six times stronger than wood plastic composites
  • The superior strength of fiberglass creates more rigid door frames that are easier to install
  • FIBERGLASS 100% 100%
  • WPC 40% 40%
  • VINYL 20% 20%

Material Strength

Energy Efficiency

  • 500x lower thermal conductivity than aluminum, so it doesn’t allow heat or cold from the outside into your home
  • Fiberglass users 78% less embodied energy than aluminum and 39% less than vinyl to manufacture
  • FIBERGLASS 15% 15%
  • VINYL 40% 40%
  • ALUMINUM 100% 100%

Thermal Conductivity

Expansion & Contraction

  • 10x more stability than vinyl in temperature changes
  • Nearly identical expansion and contraction rates as plate glass, which means tighter seal against the weather and longer lasting
  • FIBERGLASS 10% 10%
  • PLATE GLASS 15% 15%
  • VINYL 100% 100%

Material Stability


Nova Building Products was founded on the idea that fiberglass is a better way to build.  We set out to create doors and siding that were uncompromising in their design, durability, assembly and finish.  Every Nova entry and sliding door is processed on precision CNC saws and routers, built with fiberglass frames, trim and slab components, adjustable hinges are standard, and are finished with premium paints that were specifically developed for fiberglass.  Our fiberglass siding looks like wood siding, installs like vinyl siding, all while providing superior durability and dimensional stability versus fiber cement siding. Centrally located in Omaha, Nebraska we can quickly and cost effectively deliver our products to your project site.  Give us a call or shoot us an email to receive a quote on your project today.
