Insulated Steel Doors
At Cunningham Door Creations our Insulated Double Sided Steel Sectional Overhead Garage Doors are double sided steel (front and back) with 100% polyurethane core (foam filled). Unlike the “old style” single sided non-insulted steel doors that offer very little security value and are “flimsy”, making a noise while in operation and in windy conditions.
- Panels are all 40mm thick, 100% polyurethane (foam) filled with steel on all exposed sides ( double sided)
- Manufactured from hot dipped galvanised steel with a baked on, fade resistant, high grade polyester coating for maximum durability, rust resistance and colour retention.
- Energy saving polyurethane core delivers a superior R value.
- The front face of the door is available in the various designs and colours, the back face is finished in a white woodgrain striped design.

Insulated doors versus non-insulated doors:
Insulated doors are double sided and have 100% solid high quality polyurethane foam core. Insulated doors are much stronger and solid. They make very little noise and also offer a much higher security value.

Non insulated doors are also susceptible to “oil canning” which is an uneven wavy front surface that is not only unattractive but also looks defective. Our Insulated Double sided steel doors do not have these problems.
