Rising costs and depleting energy resources have impressed upon every homeowner the necessity of energy efficiency. Thanks to technology, switching to products engineered for optimal energy performance does not have to be a difficult process – especially where windows are concerned. Today, you can choose among various window products designed for:

BETTER FUNCTIONALITY

Glazing and framing are critical to the energy efficiency of the entire window unit. In fact, aside from installation, these are the two things that dictate how well the windows are able to curb energy wastage. We should understand that improved energy performance also means better overall functionality. Composite frames, for instance, are equipped to handle extreme temperature changes – which also means a lower potential for warping, rotting, and other signs of physical damage.

You should also expect energy efficient frames and glazing to be durable. Better structural integrity means that they’ll last longer, even under constant exposure to the elements. Moreover, green window components require minimal maintenance.

PART 1: THE REWARDS OF AN ENERGY EFFICIENT WINDOW

COST SAVINGS

According to the Efficient Windows Collaborative, installing energy efficient windows in a new house can help you save as much as 26% on heating costs, if you live in a cold region. Energy efficient windows in an existing home, on the other hand, can net around 15 to 16% savings on heating costs.

In a hot region, low emissivity glazing with thermally improved non-metal frames in a new house can curb cooling costs by up to 43%. And when you put the same type of windows in an existing house, you can look forward to as much as 37% savings on air conditioning expenses.

ENHANCED COMFORT

Expect better ventilation and much more efficient use of daylight in your home. Besides this, energy-efficient windows can reduce the formation of condensation on the panes – which in turn means that you’re less likely to suffer damage to your interiors by preventing the growth of mold. They have tighter seals that can also help bring down the possibility of air leakage.

Have we piqued your interest yet? In part two of our e-book, we discuss the different ways you can make your windows more energy efficient.

PART 1: THE REWARDS OF AN ENERGY EFFICIENT WINDOW

We talked about the rewards of energy efficient windows, such as better functionality and cost savings. Now, let’s discuss how you can cash in on those rewards.

If you want to upgrade your existing windows to make them more energy efficient, you don’t necessarily need a full replacement. In fact, your windows might already benefit from a simple modification. Consider this:

• Replace caulking, and weatherstrip your windows. Caulking and weathertstripping both help in plugging air leaks around your windows, and can reduce the risk of water infiltration, which can in turn lead to major water damage. Remove damaged caulk and weatherstripping, and apply anew, to ensure proper sealing. The National Renewable Energy Laboratory says that these two methods of home improvement will pay for themselves in energy savings within a year.

• Install window treatments. Curtains, blinds, and shutters are effective at keeping out glare and heat, and can deflect or block unwanted UV light that you’d like to keep out of your home. Just make sure to get treatments that you can easily manage and care for, and which suit your personal preferences, as well as temperatures in your area. Some types of window treatments even boast automatic control systems to boost daylight, and other such mechanisms.

PARTIAL WINDOW REPLACEMENTS

If some of your window components are already damaged, however, partial replacements may be necessary. These are:

Sash replacementA sash replacement is ideal for windows whose frames are still functional, with no signs of water damage or gaps. The sashes just need to be taken out to be compression-fit with new jamb-liners. The downside to sash replacements, however, is that they tend to look too bulky in some cases.

Sash and frame replacementIn a sash and frame replacement, both old sashes and frames are removed. The new components are nailed into existing jambs and stops. This kind of replacement is quite pricey, though, and some – when improperly installed – may detract from the amount of daylighting that your windows can get.

Those replacing single-paned windows in homes built before 1960 have to be extra careful about the potential presence of lead dust during the course of the project. In such a case, the entire unit must be replaced by a professional installer or contractor trained in lead-safety practices.

But what if your windows need more work? In the closing segment of our e-book series, we cover full window replacements for you.

PART 2: SIMPLE MODIFICATIONS TO WINDOWS

In the first two parts of our series, we discussed the advantages of having energy efficient windows, as well ways to make your existing windows more energy efficient. Today, we cap off the series with the ultimate method of switching to energy efficient windows: full replacement.

If you are not sure whether your window needs a full replacement, check for these signs:

• Drafts • Issues with opening or closing • Condensation between window panes • Sound penetration • Physical damage

If you ticked off most of the issues cited above, then you do need a full replacement. Here are the various considerations for energy efficient window materials that you’ll need to know about to maximize functionality, and curb your energy loads.

FRAMING

• CompositesComposites such as vinyl, engineered wood, and fiberglass are great at weathering temperature extremes without cracking. They also limit the transfer of heat. Fibrex, a proprietary composite material offered by a major reputable manufacturer, is the best choice available on the market today.

• WoodNatural wood is a good insulator, and it is one of the most aesthetically pleasing framing options on the market. When not maintained properly, however, it can become easily damaged, which is why composites that are able to mimic the look of wood are still a smarter choice.

• MetalMetal frames with thermal breakers are designed for low conductivity, which means less heat can pass through the material. They also reduce formation of condensation on the panes.

GLAZING

• Multi-pane systemDouble- or triple- glazed window units have better thermal performance over single-paned windows. Their panes are separated by a spacer, which is designed to limit heat transfer, as well as reduce condensation on the entire unit.

• Low emissivityLow emissivity or low-e glazing reflects the temperature of the interior, and keeps it that way. Low-e-glass windows, therefore, can more easily keep cool, air-conditioned air indoors – minimizing the need to boost or power up the energy in your home on a hot day.

PART 3: FULL WINDOW REPLACEMENTS

When commissioning a full replacement, make sure to remember these pointers.

• Choose the right energy performance values for your specific climate zone. ENERGY STAR and the National Fenestration Rating Council rate window products according to U-factor, Solar Heat Gain Coefficient (SHGC), Visible Transmittance, Air Leakage, and Condensation Resistance. Find products that are recommended for your region.

• Hire the right help. Energy efficient windows are great investments, and professional installation will ensure that you are able to take full advantage of the features you selected. Hire a local installer or contractor who has a lot of industry experience, understands your building codes, and offers comprehensive warranties.
