An entry system is a reflection of you and your style. What Master Seal offers is the freedom to have a door just the way you want, perfectly complementing your personality. Each made-to-order door is a creation of it’s own.

Steel Replacement Frame

The steel frame is constructed of heavy gauge galvanized steel with 10 gauge plates located on the lock and hinge sides for extra reinforcement to help keep intruders out. All replacement frames are finished with a powder coating.

  • 18 Gauge Frame
  • 10 Gauge Backing Plates on lock and hinge sides
  • Pre-finished in White Powder Coat or Primed

Every Entry Door is Equipped with Weatherstripping

Weatherstripping creates an insulating seal between the door and the door frame to make your door even more energy efficient. An integral part of three sides of the door, the weatherstripping ensures that air leakage is blocked from inside and out, so you have greater comfort and lower energy bills.

Master Seal Offers Interlocking Ball-Bearing Hinges

Years of durable operation and protection from intruders: these hinges lock into position with an interlock that prevents a potential intruder from sliding the door apart from its hinges.

More Insulation: Master Seal’s Adjust & Lock Threshold

Aluminum conducts heat and cold. But Master Seal’s thermal break stops the transmission of heat and cold in it’s tracks. A strip of plastic polymer separates two pieces of aluminum threshold to provide a thermal break between them and to keep heat and cold from transferring between the inside and out.
