If you notice any evidence of rodents getting into the garage, chances are, you might also notice a small portion of the bottom door seal has been torn away and is sitting in a frozen tundra of snow and ice cemented to the floor. Storm Shield® – the Original Garage Threshold – can provide protection from water, snow and ice from building up under the garage door. Moreover, since this threshold is made of flexible vinyl it will not freeze or stick to the bottom door seal – the overall weather tight seal will help keep the heat in and the furry ones out.
