Frequently Asked Questions

What are custom shape windows?

Custom shape windows are specialty windows designed in unique architectural shapes such as arches, circles, triangles, or other geometric forms to fit non-standard spaces.

Are custom shape windows energy efficient?

Yes. Our custom windows include energy-efficient features like insulated glass and Low-E coatings to help reduce heat transfer and improve indoor comfort.

Can custom windows match my existing windows?

Absolutely. We can design custom shape windows to complement your existing window style, frame color, and architectural aesthetic.

Are specialty windows more expensive?

Because they are custom-built, they may cost more than standard windows. However, they add significant design value and can improve energy efficiency and resale appeal.

How long does custom window installation take?

Installation time varies depending on the design and number of windows, but most projects are completed efficiently by our experienced team.

Aesthetics

  • Crystal clear views from the most advanced glass system in the industry.
  • 3/16” interior tempered pane of glass & 1/8” exterior double-strength pane of glass.
  • Sleek, low-profile frames maximize viewable glass area.
  • Equal size sashes in each frame create clean looking sight line.
  • Beveled exterior frames create beautiful architectural dimensions.
  • Integrated lift rails contribute to the overall look and feel of our streamlined frames.
  • Hidden locks do not interfere with the elegant exterior look and feel.
  • Ultra-fine screen fiber strands allow for maximum visibility.
  • Our frame drainage system helps prevent water and dirt build-up.
  • 100% non-recycled vinyl means the color and sheen will last a lifetime.

Energy Efficiency

  • Every sash is insulated with 2 panes of glass, separated by a 1” pocket that is slow-filled with argon gas.
  • The 1” pocket is sealed with a thermally-coated stainless-steel spacer that has hinges that flex.
  • 3 layers of Low-E are applied to the glass surface, making The Smart Window extremely energy efficient.
  • Each insulated glass unit has been coated with silver oxide to prevent the sun’s damaging UV rays from fading drapes and furniture.
  • Double and triple weather-stripping throughout allow virtually no air infiltration, even in high wind areas.
  • The multi-chambered heavy-duty dual wall extrusion design provides superior insulation, rigidity and durability.

Noise Prevention

  • Dissimilar glass thickness in each double-paned sash drastically reduces the number of sound waves invading your home, which means no more noisy neighbors, passing cars, airplanes, barking dogs, etc.

Security

  • Engineered with interlocking sashes, making it impossible to access the lock from the outside.
  • Our 3/16” tempered glass pane along with our 1/8” double-strength pane make it tough for burglars to break-in.
  • Our positive action locks are smartly hidden from outside views.
  • Child and pet safety features like vent latches allow our windows to remain fixed in a slightly open position.

Performance

  • Each slider sash glides effortlessly on four concave rollers that fit perfectly on top of a stainless-steel monorail track.
  • Hung and casement style windows are easy to operate with our industrial-strength hardware.
  • Heavy-duty multi-chambered frames with welded mitered corners provide the strength necessary to hold any double-pane glass system.
  • Our hung windows tilt-in and our sliders have dedicated chambers that allow for effortless removal of sashes, making cleaning the outside window panes super easy.
  • Weep-holes with covers allow water to drain while preventing dust and wind from entering your home.
  • Our lift and pull rails are extruded as part of our streamlined frames so they can never come loose like fastened-on rails often do.
