Below is a before and after of recent Hastings, MN residential garage door installation with a new door from our popular Thermacore line. This line of steel garage doors feature our sandwich construction of steel-polyurethane-steel as well as between-section seals with thermal breaks to reduce air infiltration. With several panel designs to choose from, these doors offer design flexibility, durability and thermal efficiency that will help keep your home comfortable in cold or hot climates. The particular door shown below is from our 194-series and is shown in our oak finish.
