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

All labels used 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. Print a summary of the requirements.

Commonly asked questions
What is a low volume window?
The term is used for windows and glazed doors, as well as certain kinds of skylights and solariums produced in small numbers. Most often, they are replacements for older or unique windows.
To qualify as a 'low volume window' product, they must not be produced in excess of the following:
- Windows, ≤ 750
- Glazed doors, ≤ 500
- Skylights, ≤ 1000
- Complete solariums, ≤ 25
What is an exempt fenestration product?
An exempt fenestration product is either a skylight or solarium that is exempt from the thermal performance standards established in the ORSC.
While these products are not produced in small numbers, they often must meet certain construction requirements:
- 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
