Insulation

The purpose of insulation for commerical doors, is to keep out the winter cold, or keep out the summer heat. Keeping your utility bills down, is not only a focus for residential properties, but commercial properties as well.

Doors provide access to a room and create a barrier to air flow when closed. Insulation factors are limited to the depth and construction of the door itself. Note! A door can't provide the same insulation as a wall.

Steel / Hollow metal doors may or may not be insulated. It is advisable to use an insulated door for customer entries and service doors. Not all doors have to be insulated. Non-insulated doors are less expensive.
