GRAVINA’S IS THE PLACE WHEN IT COMES TO REPLACING YOUR WINDOWS
Interested in replacing your windows or patio doors? You’re in the right place. When it comes to replacing, Marvin strives to make the best replacement windows and patio doors, from energy efficiency to durability the beautiful design.
Today, there are established standards that make it much easier to see how various windows and doors stack up against each other. When shopping for your windows and doors take the following factors into consideration.
U-Factor correlates to the rate of heat transfer. The lower the number, the better a window is at keeping heat inside a building. The U-Factor is key in regions with cold winters. Just remember: the lower the U-Factor, the lower the rate of heat loss through a window.
This is a more important measuring tool than the R-value – which measures resistance to heat loss. Many people are familiar with the R-value because of its use in home insulation. But actually, for windows and doors, U-factor and solar heat gain coefficient are more important measurements.
Solar Heat Gain Coefficient
Solar Heat Gain Coefficient measures how well a product blocks heat from the sun. In warm climates, the lower the number, the better. Here you want to keep heat out by choosing windows that reflect solar radiation. Less heat coming into the home means lower air-conditioning costs and a reduced carbon footprint. In cold regions, your windows can also help you take advantage of solar radiation, which is free heat that eases the workload of your furnace or other energy-powered heat source. A higher solar heat gain coefficient means a window will allow more heat to pass through.
Design Pressure Rating
Design pressure (DP) Rating measures the amount of pressure a door or window will withstand when closed and locked. Each DP rating also establishes other performance factors such as water penetration, air infiltration, structural pressure, forced entry and operational force. The higher the DP numbers, the better the performance. Look for the certified hallmark of the Window and Door Manufacturers Association.
Windows are one of the key elements to consider when looking to increase a home’s energy efficiency. Many factors come into play when choosing the right window from climate to desired conservation efforts. Marvin Windows and Doors is the leader in energy-efficient solutions. Know what to look for when choosing your next window.
Know your climate. Different glass works best in different climates, so where you live impacts what you should buy.
Coating a glass surface between each pane with Low E material can block a significant amount of heat transfer, reducing your home’s need for energy consumption.
