I am researching a floor for my garage so I sent Armstrong an email with some questions about their VCT and this is the response I received. I know many of you have VCT in your garages so I figured I would post this.
"Dear Chris:
Thank you for contacting Armstrong World Industries, Inc. about our vinyl composition tile.
In order for flooring materials to be installed in residential or commercial garages, the flooring material must meet the International Residential Code R 309 for Garages and Carports for one and two family residential buildings or the International Building Code 406.2 for all other buildings. The codes outline garage floor surfaces shall be of approved noncombustible material. Armstrong flooring products do not meet this standard and therefore should not be installed in parking garage areas where vehicles will be parked on the surface of the Armstrong floor.
In addition Armstrong flooring should only be installed in temperature-controlled environments. Normally garages are not temperature controlled areas. After installation, the temperature should be maintained at a minimum of 55 degrees. Most garage floors have had gas and oil dripped or spilled on them. This residue in the substrate will inhibit the adhesive from working properly. Automobile fluids, such as brake, transmission and oil, if leaked onto the resilient flooring can get into the joints of the tile and break down the adhesive creating a bonding issue and a possible installation failure. The oils and antioxidants used in the manufacturing process of rubber tires will cause a permanent yellow discoloration to any resilient (vinyl) flooring. Also, exposure to the moisture from rain, snow or sleet and varying temperatures will have a damaging affect on both tile and sheet flooring.
Once again, thank you for contacting Armstrong. I hope this information is helpful. If you have any further questions, please feel free to contact us again by e-mail at [email protected] or by phone at 1-877-276-7876 press 2, 3, 3.
