PART 2 - PRODUCTS

SPEC NOTE - Frenette (Aug/19/2009): The use of thinner strip flooring may reduce the effects of expansion and contraction due to changes in relative humidity. Recommended flooring is 26 x 57 mm, however 20 x 38 mm flooring is recommended for installation in areas of high humidity. In retrofit projects, verify the dimension and performance of the previous floor assembly to assist in selection of proper material. Coordinate floor depression requirements with manufacturer and total thickness of entire floor assembly. Edit to suit project application. 

SPEC NOTE - Frenette(Aug/18/2009): Two systems are specified in this Section.

SPEC NOTE - Frenette (Aug/19/2009): Other Finishes available are oil-modified urethane finish, moisture cured urethane finish and water-based finish. Moisture cured urethanes produce a hard and moisture resistant finish, but are difficult to apply and may cause side bonding in the strip flooring, resulting in cracks in individual wood strips. Water-based finishes are environmentally friendly, but may also cause side bonding if not properly prepared. To prevent side bonding when using water-based finish, the sealer coat must be oil-based. Never apply oil-based finish over water-based finish. The use of oil-modified finish has good durability. 

SPEC NOTE - Frenette (Aug/19/2009): Water finishes are required by the Department of Education Performance Guidelines unless the use of oil-based finishes are pre approved or required during the preliminary design stage. When using oil-based finishes, verify that stakeholders (Project Manager, end-user, etc.) are notified of floor finishing schedule to limit occupant exposure to fumes. Oil-based finish is not recommended on HPB (High Performance Building). All oil-based finishes must meet the HPB (High Performance Building) requirements such as maximum allowed VOC limits. 

SPEC NOTE - Frenette (Aug/19/2009): Edit as required or delete article below when not using water-base finish. Always confirm allowed VOC limits with latest version of HPB (High Performance Building) documentation.
