Window Insulation Essentials
The essence of good insulation lies not only in the walls or the roof but also in the windows.
Proper window insulation helps maintain a comfortable internal temperature. It can also substantially lower your energy bills by retaining the heat generated inside your home.
Nonetheless, even the best windows do not last forever, and their insulation lessens over time. Caulking, for instance, lasts only ten years, after which you have to reapply it.
We know it may be slightly time-consuming to assess what exactly is wrong with your windows, find a solution, and then apply it. But we cannot stress enough how important this process is – for prolonging your window’s lifespan, maintaining the integrity of your house, keeping or even increasing your property value, and your comfort.
Checking a Window’s Insulation
Identifying leaky windows is the first step in our quest for improved insulation. Wondering how? Well, it’s quite simple.
You can use incense sticks or candles to visually identify air movement indicating leaky areas. Just carefully move the lit incense stick or candle around the window frame and look for smoke movement or flickering that signals drafts.
Once you identify the leaks, address them promptly with weatherstripping or other sealing methods.
Furthermore, you should check the caulking around your windows. If it has been applied unevenly, there’s a high chance gaps are still there, and they let air and water in. You should also look for gaps between the windowsill and the frame.
In addition, if you have double- or triple-pane windows and notice condensation between the panes, you’re likely dealing with a broken window seal, which affects the unit’s insulation properties.
Last but not least, check for signs of damage around your windows. For example, if the wall surrounding it is moldy, your windows may have insulation problems, thus letting water in.
So, is there something you can do? It depends on how damaged your windows are. If we’re talking just about some gaps that require caulking or weatherstripping, you can definitely solve the problem yourself. If it’s a broken window seal, a more serious leakage, or if your windows have exceeded their lifespan, you’ll likely need to hire a repair professional or replace them altogether.
Sealing the Gaps: Caulking and Weatherstripping
Having pinpointed the leaks and grasped the significance of insulation, it’s time to fill those gaps! Caulking is an effective method to enhance insulation by sealing gaps around window frames.
To maximize insulation, you should apply the caulk inside and outside the window frame to seal air leaks effectively.
Choosing the Right Caulk
Choosing a suitable caulk is pivotal for efficient window insulation. It should withstand temperature changes, friction, and wear and tear.
The preferred caulk types are:
- acrylic latex caulk (mostly for interior window parts)
- silicone caulk
- polyurethane caulk
- butyl rubber caulk (the most durable one, perfect for extreme weather conditions)
Don’t forget that you should not apply the caulk on movable window parts, weep holes, trimmed-out windows, and above the frame.
Weatherstripping Techniques
Another effective, inexpensive method for window insulation is weatherstripping. While caulk is used for stationary components, weatherstripping is designed particularly for movable parts.
It’s essential to choose a type of weatherstripping that withstands weather and temperature fluctuations, friction, and wear and tear. For example, a tension seal is often used on the inside track of a double-hung or sliding window. Reinforced foam and rolled vinyl are used on the bottom or top of the window sash. Felt is usually applied around the window sash, while reinforced silicone is preferred for a window stop.
Installing Thermal Window Treatments
If you’ve sealed any gaps and feel that your windows are still not perfectly insulated, you can turn to other options to enhance their energy efficiency. These include thermal curtains, blackout blinds, and Low-E coatings.
Selecting Thermal Curtains
Thermal curtains are designed specifically for insulation, keeping cold air out in the winter and warm air out in the summer. Thermal curtains are made from multiple fabric layers, which include highly insulating materials. So, they basically create a thermal barrier between the window and the interior of your home. In addition, thermal curtains can also block sounds, thus making your home even more comfortable!
Choosing suitable thermal curtains is of paramount importance. Just make sure you measure everything correctly because the curtains must cover the windows completely. Or, even better, they can cover the whole wall from top to bottom.
Insulating Window Film
If you’re looking for a budget-friendly solution to insulate your windows, you can try an insulating window film kit. These products are usually quite easy to apply – you’ll just have to use a double-sided sticky tape and heat the film with a hair dryer so that it shrinks.
Magic’s Blackout Blinds
To further enhance window insulation, consider combining blinds with curtains. This combination not only enhances window insulation but also provides homeowners with control over privacy and light.
You can opt for Magic’s retractable blackout blinds. They are so efficient in insulating a window that the unit’s U-factor lowers to 0.17 when the blinds are in use! In fact, they act like a third glass pane and increase a window’s energy efficiency by 40%. In short, they are perfect for Canadian weather!
Low-E Coatings
Low-E coatings are added directly to the glass surface. A Low-E coating is a thin, transparent layer that helps the window surface regulate the heat it absorbs and re-radiates. As such, a Low-E coating will lower your window’s U-factor (the rate of heat transfer) and solar heat gain coefficient (how much solar heat enters through the window), at the same time maintaining a high visible transmittance. Therefore, Low-E coatings do not affect the amount of natural light that passes through your windows.
There are two types of Low-E coatings. Choosing the correct one will yield better insulating results. So, if you live in colder climates, you should opt for passive Low-E coatings. They are added to surfaces 3 and/or 4 of a window. Conversely, if you live in warmer climates, you should consider solar control Low-E coatings. These coatings are added to the 2nd glass surface.
Innovative Insulation Solutions: Window Films and Inserts
Having discussed traditional insulation methods, it’s time to venture into innovative solutions!
For example, you can add window films that have insulation properties. A window film is a thin material added to the glass surface. It is usually made from polyester laminate and treated in various ways to improve a window’s look or performance.
Window films regulate temperature by reflecting sun heat away from your home in summer and retaining heat in winter. In addition, window films protect the interior of your house from harmful UV rays. This doesn’t only insulate your home but also keeps your furniture safe from sun damage.
Another solution is installing window inserts. They are a budget-friendly alternative to window replacement. Window inserts are basically added to the existing frame, creating a tight seal around it, thus insulating your property. Some window inserts even have soundproofing and UV protection properties.
Using Household Items for Insulation
If you’re on a tight budget and can’t afford more expensive window treatments at the moment, you can resort to some temporary solutions with household items.
First, you can use bubble wrap. It’s best to use one with larger bubbles. As mentioned, this is just a temporary solution because bubble wrap doesn’t look aesthetically pleasing and won’t keep drafts away indefinitely.
Draft stoppers can also help you add extra insulation to your windows. You can create a draft stopper by:
- Measuring the width of the door or window
- Cutting fabric to the suitable dimensions
- Sewing it into a tube shape
- Filling it with insulating materials such as rice, beans, or sand.
Draft stoppers should be placed snugly against the bottom of doors and windows to prevent cold air from entering through these spaces. If you don’t have time to make a draft stopper yourself, you can probably find one at the home improvement stores in your area.
Replacing Existing Windows With Insulated Ones
If the budget allows it, you may want to consider replacing your windows. This is paramount if they are old and have surpassed their life expectancy. Replacing or retrofitting your windows may seem expensive at first, but the investment is totally worth it. Energy-efficient windows won’t only lower your energy bills but also significantly increase your property value.
