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 its own.
SafeGuard™ steel doors are guaranteed not to warp, split, or delaminate for as long as you own your home. See warranty for additional details.
The Dual U-Channel Steel Door Edges are custom made to the customer’s specific door width instead of the conventional width-cut-down door slab. The 3-Dimensional design provides structural strength against warping and resistance against splitting from break-in attempts. In addition, the full perimeter of the door is sealed with a polymer thermal break providing greater insulation value and preventing any exposed steel edges.
The steel frame is constructed of heavy gauge galvanized steel 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.
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.
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.
Aluminum conducts heat and cold. But MASTER SEAL’S thermal break stops the transmission of heat and cold in its tracks. A strip of insulating 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 outside.
