EXTRUDED ALUMINUM

Extruded aluminum is used on window and door exteriors to provide additional protection and minimize maintenance compared to an all-wood window. Aluminum can either be extruded or roll-formed, and the difference in strength can be compared to an industrial chair versus an inexpensive lawn chair. Extruded aluminum is used for cladding because of its strength and weather resistance. It’s important to remember that clad windows and doors are different from products that have all-aluminum frames, which are typically less energy-efficient than the alternatives.

U-FACTOR

Simply put, U-factor measures how well a window keeps heat inside your home. It’s a measure of total heat flow through a window or door from room air to outside air. Lower numbers indicate greater insulating capabilities. It’s a particularly important measure for climates with colder winters.

SOLAR-HEAT GAIN

If U-factor denotes how much heat leaves your home, the Solar Heat Gain Coefficient (SHGC) measures how much radiant heat enters your home. All you really need to remember is: The lower the number, the less heat a window lets in.

VISIBLE TRANSMITTANCE

The amount of visible light transferred through a window. Low E coatings can reject solar heat gain without significant reduction to visible light passing through the glass.

Does my window need to be ENERGY STAR certified in order to be energy efficient?

No. While an ENERGY STAR label can be helpful in identifying energy-efficient windows, every home is unique. ENERGY STAR provides a one-size-fits-all guideline but does not take into consideration, for example, the orientation of the house or the number or size of windows and associated Solar Heat Gain. A window expert like your Puertana dealer can help determine which products will work best for you. ENERGY STAR also recognizes products that meet high energy-efficiency guidelines. Puertana offers the industry’s widest selection of wood and clad wood products that meet these rigorous criteria. Link to Most Efficient product list.

Can you help me to better understand the numbers? What’s a good U-factor number? What’s a good SHGC?

Different homeowners seek out different levels of efficiency, but a “good” U-factor is <.30. A “good” Solar Heat Gain rating, meanwhile, on a scale from 0 to 1, is relative to climates in different regions. Low SHGC numbers are best for southern climates where there’s intense sun exposure, whereas higher SHGC values make the most sense for regions with cold winters.

Can you explain Low E coatings?

The ability of a material to radiate energy (heat) is called its emissivity. Extremely thin coatings of special low emissivity (Low E) metallic material are applied to glass panes used in windows and doors to boost their energy efficiency. Low E coatings, usually applied to the inside layers of insulating glass, manage the amount of light and heat either conducted through a window or reflected away from it.

Are triple pane windows the best? The more panes the better, right?

Not always. Triple-pane windows work best when enhanced energy performance is a key objective. Tripane offers a range of low-E configurations for greater Solar Heat Gain control, including panes filled with argon or krypton-argon gas for added efficiency. But no matter how many panes there are, if the window is poorly constructed, poorly installed or allows air leakage, it will not
be efficient.

INSULATING GLASS (IG)

Two or more glass panes separated by energy efficient inert gas or air to reduce thermal transfer.

LOW E

Low E stands for low emissivity. Microscopically thin, transparent metal or metallic oxide layers deposited on a glass surface suppress radiative heat flow and reflect interior infrared energy (heat) back to the inside, reducing heat loss through the glass. Various Low E coating options can manipulate heat gain to match different climate needs.

GAS FILLS

Argon or krypton mixes slow the movement of warm and cool air in IG airspaces and improve thermal performance.
