Fiberglass: Energy Efficiency, Strength, Durability.

High-tech fiberglass pultrusion technology offers an exciting alternative to metal, plastic, or wood frame windows. Fiberglass has all the advantages of competing systems, with none of their disadvantages.

The ultimate window-frame material, pultruded fiberglass, differs from common fiberglass used in pools, boats, and storage tanks. Continuous strands of glass are saturated in a thermoset resin, and pass through a heated die. They are pulled through, the die, rather than pushed or extruded, through the die - hence the term `pultrusion.’

Fibertec fabricates these dimensionally stable window lineals into fiberglass window frames. By filling the fiberglass frames with foam insulation and glazing them with high efficiency insulating glass, Fibertec has produced the ultimate high performance window

Fibertec's fiberglass window and door manufacturing system meets the needs of designers and builders who wish to go beyond the limitations inherent with metal, plastic or wood frame fenestration. Pultruded fiberglass has proven to be a superior material in five ways: dimensional stability, thermal insulation, durability and aesthetics, and `environmental friendliness’.   In the pultrusion process, continuous fibers reinforcing in roving or mat/roving forms are drawn through a specially formulated resin bath to coat each fiber with a thermosetting resin mixture. The coated fibers are assembled by a forming guide and then drawn through a heated die. Cure of the thermosetting resin is activated by heat in the die and catalyst in the resin mix. Unlike aluminum or PVC which are pushed through a die and then worked at the exit end, the pultrusion process pulls the material, hence the name, through the die and the resulting profile is cut to length as it leaves the die. It is then ready for use without further forming or treatment.

Energy Efficiency, Strength, Durability.


~ Minimal expansion and contraction - Fiberglass frames reduce the likelihood of unit failure and caulking cracks - maintains superior performance with regard to air/water infiltration
~ Obtains a high R-value - Fiberglass frames provide savings of approximately 20-40% in heating/cooling/energy costs over other window frame materials
~ Comfort and more consistent room temperatures in larger windows areas
~ A reduction in moisture and condensation, saving on costly repair to damaged wallpaper and masonry
~ Fiberglass has a high resistance to corrosion and rotting - good for seaside applications or other chemically sensitive environments
~ Fiberglass frames ensure a longer life expectancy than vinyl, wood and aluminum-clad - deters future service and maintenance costs


Stronger Fiberglass Frames allow:
~ Smooth operation/no stress on hardware mechanism and guaranteed prolonged life expectancy
~ Slimmer frames with more glass area - maximizes sunlight and viewing area
~ Greater resistance to forced entry - increased security
~ Larger units/unique window sizes and shapes are possible, to meet unique customer specifications


Durability ~ High resistance to warping, twisting, rotting, cracking or shrinking.
~ Fiberglass frames will hold paint better than other materials and is a natural U.V. protector - will not fade, chip or crack.
~ Fiberglass is a paintable product - it can be painted during the manufacturing process or on site by the customer - allows customer to change colour at any time
~ Properties of fiberglass ensure a window/door product will perform as well in year 3, 10 and 30 as it performed on day one

The key features and benefits of selecting fiberglass window frames as opposed to conventional wood or vinyl windows are as follows:
  1. Ease of window installation
  2. Guaranteed prolonged fiberglass window frame life expectancy
  3. Slimmer fiberglass frames and mullions, increasing glass to frame ratio, increasing maximum sunlight and viewing area
  4. Ability to design larger window units due to its durability
  5. Ability to withstand high levels of wind load resistance, which far exceeds CAN-A440 M90 CSA Window Standards
  6. Increased security, offering greater resistance to forced entry
  7. Savings in energy costs
  8. Reduction in moisture and condensation
  9. High resistance to sound transmission, reducing exterior noise
  10. Consistent room temperature in large window areas
  11. Consistent contact of weather-strip and positive seal against frame and sash, keeping air, water and dust out
  12. Uniform movement of glass and fiberglass frame, reducing the likelihood of unit failure and caulking cracks
