MPI is a global custom door and frame manufacturer that is only limited by the imagination of the architect or designer that works with us. Excellence in quality and customer satisfaction, as well as our impressive capabilities when it comes to custom door and frame fabrication, has brought us recognition as a highly respected leader in the manufacturer of standard and custom steel doors and frames.
Our fabrication processes have been carefully developed to provide total quality control to our team of specialists. At the same time, our state-of-the-art fabrication processes still allow us complete flexibility in order to accommodate even the most complex of architectural designs. Great emphasis is placed on details rarely seen in the finished product to ensure complete success for our client's project.

Polyurethane Polyiso Doors
Report
MPI uses a polyisocyanurate slab in place core for our polyurethane style doors.
Typically polyurethane is a foamed in place application as the slab form is very brittle and unstable.
Polyisocyanurate offers many benefits over it's polyurethane counterpart, such as: stable rigid form, resistance to water and solvents, higher temperature stability, and resistance to burning.

Thermal Products
Report
Steel stiffened, polystyrene and polyurethane doors were included in the tests.
Ratings are significantly better than those obtained from tests performed on wood and aluminum doors.
Thermal performance tests measure a door's thermal conductivity known as "U-Factor" and its inverse which is termed thermal resistance or R-Value.
U-factors have units in the Inch-Pound system of BTUs per hour per square foot per degree (Fahrenheit) or Btu/hr-ft2-F.
R-values have the rather unintuitive units of hr-ft2-F/Btu.
