Energy-efficient windows are becoming an essential part of building design, with electricity costs constantly rising. Hiring the right windows replacement companies will help you on how to frame for a window installation and more processes.
When selecting new windows for your home, it is vital that you understand their different characteristics and how each one influences its overall thermal performance (how well they insulate).
There are four main window fittings: double-glazing, triple glazing, secondary glazing, and reflective film overlay.
Double-glazed units consist of two panels separated by air or gas-filled space to provide insulation. This type can come already installed (in some cases) or included in your window installation quote.
The more panes within the unit, the more insulating properties it has, i.e., double glazing has much better insulation than single glazed windows.
As with double-glazing, triple-glazed windows contain air or gas-filled space between the panes to improve insulation. However, a third pane is added, which may or may not contact the two other panels (i.e., sandwiched in between them).
This vapor barrier helps reduce heat loss and condensation inside the home during colder months when warm moist air escapes through the window and condenses on the cold pane’s surface.
Secondary glazing involves adding a second layer of glass onto an existing unit, either single or double glazed. Doing so aims to provide an extra layer of insulation to your home, particularly in colder climates.
The best energy-efficient windows use this method (also known as Low-E treatment or sun control film) which can be used on all types of glass/window designs, i.e., double, triple, and single glazed.
Low-E films reduce heat loss in winter by reflecting heat into the room where it is needed. During the summer months, they prevent unwanted heat from entering the room by blocking out the most visible light (90%+) while allowing short wave radiation that passes quickly through the glass.
Warming devices such as televisions, lamps, computers will receive less glare which assists in minimizing eye strain and fatigue.
This film does not damage or alter the original window’s appearance (if installed correctly) and is used in conjunction with double, triple, and more glazing units. The main benefit of this method is that it can be retrofitted onto existing windows to improve their thermal performance.
For example, installing a secondary layer of glass will significantly reduce heat loss in winter. While adding Low-E films minimizes the amount of unwanted solar heat entering your home during the summer months when you may require less cooling due to effective insulation.
Choosing the best energy-efficient windows for you: Before buying new windows, ensure they are Energy Star rated as these have been independently tested and proven to be up to 30% more energy efficient than standard fittings.
When choosing windows for your home, several factors must be considered, including location, climate/weather conditions, home style, and more. It is recommended that you consult a professional installer if you are unsure what type of window fittings are best suited to meet your needs.
Choosing the best energy-efficient windows can be a big decision so consult a professional to ensure you select the best option for your home/family needs. If you are willing to research what’s available, you will eventually find great possibilities in affordable pricing.
- They improve the overall thermal performance of your home, thus reducing heat loss in winter and unwanted heat gain during the summer months.
- The windows lower heating costs in winter and reduce cooling costs in the summer.
- Improves occupant comfort by preventing heat/cold loss or gain, reduces eye strain and fatigue from glare, allows for better natural lighting during daytime hours.
How much does window installation cost? If you consider the overall benefits, energy-efficient windows are very affordable. They will reduce heating and cooling costs while improving comfort levels for your home’s occupants even in extreme weather conditions (hot/cold).
Either way, it is essential to research different brands and what they offer before choosing which products best meet your needs. You can then select Energy Star-rated products so you know they have been independently tested and proven to be up to 30% more energy efficient than standard fittings.
The cost of installing energy-efficient windows can range anywhere from several hundred dollars to over $2,000 depending on the window size, brand name, design features, and more.
As discussed earlier in this article, there are many factors to consider when choosing windows, so it is essential to consult with a professional on all the options before making your final decision.
It all depends on each homeowner‘s specific needs/requirements and whether they are looking for thermal efficiency, affordability, and more. Energy-efficient windows provide many benefits that standard window fittings cannot offer.
That includes but is not limited to increased comfort levels of room occupants reducing heating costs in winter while improving cooling costs in summer months, thus providing cost-effective solutions for all seasons.
- Window replacement only benefits homeowners who want to change their old/outdated designs/fittings, e.g., make their own house look more significant from the outside by adding larger panes of glass famous for older homes with smaller windows.
- Replacing old, drafty windows can also improve home energy efficiency, but the cost to install the new fittings could be up to twice as much depending on what you use and how labor-intensive it is to complete the installation process.
If you’re not entirely sure about upgrading your current window fixtures, contact a qualified professional who can advise on your options and whether it’s cost-effective/beneficial to replace or add secondary glazing later down the track.
A reliable windows installation company will help you measure a window for replacement. Choosing low-priced window fittings might seem like an economic decision, but it could end up costing you more in the long run.
If you purchase poor-quality products, they may not have proper thermal efficiency or draft sealing capabilities, so your heating and cooling bills could be significantly higher.
Furthermore, these products will most likely not offer longevity with regular use – something you want from energy-efficient fixtures that have been designed with quality in mind.
