Gasket Installation Tips

Cold Gasket Installation

During the cooler times of the year or in cold environment, it is important to handle vinyl door gaskets properly. This even includes removing them from their shipping cartons as vinyl becomes stiffer and less flexible in temperatures below 60°F (15.6°C).

While using vinyl is the standard for the industry, gaskets made from vinyl are generally installed in and around door openings that are exposed to normal room temperatures and/or are installed over door openings that are heated electrically.

For the best results, it is recommended that gaskets be warmed up to room temperature prior to removing them from their shipping carton. This is especially true for vinyl gaskets that have a hard mounting base.

Before to installing vinyl door gaskets, it is recommended that they be moderately heated to increase flexibility and remove any wrinkles that can affect their ability to seal the area properly.

Gaskets may be heated using the following means:

  • By placing the gasket in hot, but not boiling, water.
  • By placing the gasket in a warming oven turned to low heat no greater then 105°F (40.6°C). Generally this is the least preferable method for heating as most household ovens operate with much higher temperatures. Higher temperatures will scorch and/or melt any gasket.
  • By placing the gasket in a hot room, such as a furnace or boiler room that does not exceed 105°F (40.6°C).
  • By placing the gasket in the close proximity of a portable electric heating device such ad a hair dryer or heat gun.

Never heat a gasket for more than one hour.

After installation, it may be necessary to apply additional heat to the gasket to assist in it’s “settling” to the door. It is sometimes necessary to use your fingers to gently pull the gasket to a level position if there are dips in the contact area of the gasket.

As a general rule, new gaskets can take several days to adjust to the door to seal properly. Sometimes door hinges may have to be adjusted to compensate for a slightly thicker, new gasket.
