FAQs about The Misconception About R-Value and Door Insulation Coupon?

What does R-value mean on a garage door?

The higher the R-value, the better the insulation. R-value is commonly used to measure the insulating properties of individual materials like batt insulation or foam insulation. In the context of garage doors, R-value accounts for an individual door section, not the entire assembly like U-factor does. ...

Is a high R-value garage door a good insulator?

When a material’s R-value is high, it does not conduct heat well, making it a good insulator. The US Dept of Energy considers “High R-Value walls” to be R-40 or above for Zero Energy Ready. Currently, there are no Energy Star rated garage doors. ...

Are R-32 garage doors better than R-16?

Note: An R-32 does not offer twice as much thermal resistance or twice the energy savings of an R-16 value. This chart indicates that an R-32 offers 7% reduction in heat transfer (and a 7% energy efficiency improvement) over an R-16 – not 50%. Chart source: Amarr Garage Doors – The Truth About R-Values 2013. ...

What is the difference between U-factor and R-value in garage doors?

In the context of garage doors, R-value accounts for an individual door section, not the entire assembly like U-factor does. While both U-factor and R-value provide information about insulation performance, they represent it in slightly different ways. U-factor directly measures heat transfer, while R-value measures thermal resistance. ...

How do I choose the right R-value for my garage door?

Once you know how the space is primarily used then you can decide on the R-Value that suits your needs. If your garage door opens several times a day then a high R-Value can be overkill. The slightly warmer air in the garage will escape every time the door is opened. ...

Is a high R-value garage door a good idea?

If your garage door opens several times a day then a high R-Value can be overkill. The slightly warmer air in the garage will escape every time the door is opened. If your garage is a workshop area or you heat your garage but only open it in the summer then a slightly higher R-Value may be appropriate. ...
