Low-volume window labels

The Low-Volume Window Label Program works to help manufacturers and installers comply with the Oregon Residential Specialty Code (ORSC) fenestration provisions.

Low volume windows and exempt fenestration products must be properly labeled before they can be sold in Oregon.

What are...

Low-volume windows?

Windows and glazed doors, as well as certain kinds of skylights and solariums produced in small numbers. Usually, they are replacements for older or unique windows.

To qualify, they must not be produced in excess of the following:

  • Windows, ≤ 750
  • Glazed doors, ≤ 500
  • Skylights, ≤ 1000
  • Complete solariums, ≤ 25

Exempt fenestration products?

Either a skylight or solarium that is exempt from the ORSC thermal performance standards. These products must meet certain construction requirements to qualify:

  • Complete solariums that have a minimum of 0.5 inch (12.7 mm) space between the panes,
  • Skylights that have a frame type that is either aluminum with thermal break, aluminum with vinyl, or wood, and a glazing type that is a minimum of either 0.5 inch (12.7mm) airspace between double layered low-e or triple-layered acrylic.

What you need to know...

All labels must:

  • Be imprinted, not handwritten
  • Face the interior of the dwelling
  • List either the U-factor or U-factor class of the product
  • Remain attached to the product until a building inspector inspects and verifies the labeling

All low volume and exempt fenestration products must comply with product-specific labeling requirements.
