Thermal Break Technology Revolutionizes Iron Door Industry

Many have tried, but have only managed a partial solution. Donatello Doors Polar Shield™ technology has now made wrought iron doors thoroughly suitable for cold climates.

The temperature difference between inside and outside can be over 100º F in cold winters and steel doors conduct that heat right out the door. When the cold from outside meets the warmth inside, it can cause condensation or even frost on the inside of the door, making a regular wrought iron door inappropriate in areas with cold winters.

Polyurethane foam in the core of a wrought iron door does very little to stop heat flow because the steel itself conducts the heat right around that insulation. Polar Shield™ has thermal breaks in every part of the door – effectively breaking the flow of heat from the inside to outside. With the addition of our proprietary seals, made to withstand the greatest temperature variation without cracking or becoming brittle, Polar Shield™ keeps the warm in and the cold out.

A typical wrought iron door has a U factor of 4.34, compared to 0.41 for Polar Shield™ – representing a 1000% improvement in insulation. While essential for colder areas, this technology also saves energy in warm climates where Polar Shield™ doors can qualify for an Energy Star rating. Energy savings can be well over $100 per month, easily justifying the higher cost of Polar Shield™.
