Many manufacturers use R-values to measure the energy efficiency of their doors, which is a number that’s calculated by the thickness of the insulation and its chemical properties. It doesn’t, though, factor in the door’s construction, so note that the R-value is only a partial answer. You may have heard that a garage door should have an R-value of at least 10. The higher the number, the better the insulation value.
Compare the value of “10” to the R-value of our Infinity Traditional Collection
, which comes with triple-layer construction that combines the strength of steel with state-of-the-art CFC-free polyurethane thermal efficiency. It’s no surprise, then, that this is our most energy-efficient garage door—one that comes with an R-value of up to 19.40. Because of its interior wind load reinforcement system, this door can withstand up to Category 3 hurricane winds up to speeds of 130 mph.
At Presto Garage & Gutter, we only offer the best products, which doesn’t translate into the cheapest. There is another key benefit of installing a quality garage door, though: its exceptionally high ROI.
