Wayne-Dalton's Foamed-In Place Insulation
Patented, foamed-in-place polyurethane core.

The core of our popular models, the 9700 and 9600 provide an insulation R-value of 10, more than twice as much as common polystyrene insulation board the same thickness. It's chemically bonded to each steel section, creating a composite structure with higher strength, greater rigidity, improved dent-resistance and better thermal protection. (Model 9100 provides an R-value of 8 while Model 8300 is 11.)

To understand how R-value and heat flow are related, it is easier to think of your garage not as a single entity, but as a part of a system with the external environment. As with most everything in nature, heat will want to redistribute itself in an effort to reach a state of equilibrium, or equal temperatures on both the inside and the outside of your garage. To do this, heat must pass through the garage door to reach the other part of the system.
Door quality impacts your utility bills. Your garage door is typically the largest opening in your home.

In the summer, heat is produced outside of your garage. Thus, it is naturally hotter outside of your garage than inside and heat will try to "get in" to even out the system. If a garage door has an R-value of 3, 1/3 of the heat will get through the door and into your garage. This does not mean that the internal temperature will be 1/3 of the external temperature, though. It just means that as more heat is produced externally, 1/3 of it will enter your garage. Insulating your garage door can help keep the heat out.

The opposite is true in the winter. Heat is produced inside your garage in the winter, either by heating or by the effects of the sun. As it is cooler on the outside of the door, heat will try to escape to the outside through the door and other parts of your garage to even out the system. If keeping your garage warm in the winter is a priority, then choose a door with a higher R-value.
Two Types of Insulation

Polyurethane foamed-in-place insulation
Our most popular polyurethane foamed-in-place insulated doors have  R-values ranging from 11 to 8. The doors are manufactured with polyurethane foamed-in-place insulation using a patented process. Polyurethane insulation delivers twice the thermal performance of polysterene insulation of the same thickness! It also adds strength and rigidity to the door panels and helps dampen sound transmission.

Expanded polystyrene insulation
 Expanded polystyrene insulation offering good thermal performace with an R-Value less than 6. Polystyrene insulation are rigid panels placed inside the door sections at time of manufacturing.

Bottom Weather Seal

In addition to insulation, our doors have a bottom weather seal. The bottom weather seal blocks drafts and helps save energy. It remains flexible even in extreme cold to keep the bad weather outside.

Insulation Means More Than Energy Savings

“R-values” have become familiar benchmarks for shoppers to compare the insulating ability of a wide range of home building products. That’s smart. But there are other things about garagedoor insulation that people should know. The type of insulation makes a difference. The two most common insulating materials are polyurethane and polystyrene. Polystyrene insulation is usually used in rigid sheets inserted into garage door cavities. Polyurethane is a foam that expands and bonds to surfaces when injected into the cavity. Inch for inch, polyurethane insulation is twice as effective as polystyrene.

Composite panels have structural properties. The polyurethane foam chemically bonded to the steel section creates a composite structure with greater strength, more rigidity, improved dent-resistance and better thermal protection.

Insulating against neighborhood noise, too. The same properties that help reduce the loss of energy, also give polyurethane insulation excellent acoustic properties. An insulated garage door can significantly reduce the intrusion of street noise into the home – especially important when there are bedroom or other living areas above or adjacent to the garage.
