Heat Control Window Film Buyer’s Guide
Windows play an important role in ensuring the comfort of your home’s interior. Nevertheless, even the most tightly sealed windows allow at least a little sneak peek of the outdoors.
Therefore, your home’s air conditioning is put to the test every summer when the temperature rises to 90 degrees. Additionally, you may have some months out of the year where your utility bills are higher than they need to be.
You can opt for a much more affordable alternative before investing in special windows. Easy to install, window film provides privacy and protects your windows from harmful ultraviolet rays.
Apart from all that, there’s a simple fact that different films give your windows an entirely different look. You can either choose to shade your windows simply or create an ornamental look.
Window films with stained glass patterns are very popular, so you may want to consider that for your room.
Choose a film that has a light transmission rating of 60-70% if you want your room to have more natural light. A 49% light transmission is, however, generally found to be an acceptable compromise between allowing some natural light in, while keeping glare at an acceptable level.
There will still be some movement and shadows visible, particularly with films that take advantage of some natural light. You should check that the film you choose will provide maximum privacy before using it in an area such as a bathroom or bedroom.
Knowing the differences in light-blocking properties of each type of film is important before you begin shopping. Your privacy film’s ability to block out heat from the outside depends on this factor.
The reduction in sunlight can, however, have its downside. Using an insulating film that is too thick will reduce natural light. The 70-percentile range is suitable for films that reduce solar heat gain while allowing for a sufficient amount of natural light to enter.
Does Reflective Window Film Reduce Heat?
One of the most effective and cost-effective methods of reducing heat in a home or office is to use a reliable window film. Additionally, window films are environmentally friendly as well as saving you money and time.
Solar heat is blocked by the film of higher quality up to 79%. Furthermore, window films protect your belongings as well as reduce glare and improve insulation. You can keep your upholstery and other items looking brand new all the time by installing window film instead of the sun shining in on them day after day.
You will likely be influenced by the film’s appearance after installation. Small windows and bathrooms will benefit from window films with a stained-glass appearance.
There are plenty of color options to choose from if you’re covering a sliding glass door or just want something less obvious. If you want a subtle tint for your window, you can choose from black, blue, brown, or silver.
As long as you choose a film that requires no glue or adhesive to install, installing your window film should be fairly easy. Make sure you buy an extra-large size when you buy other privacy films so that you can cut it during installation.
Heat loss is a problem regardless of how well insulated your home is. Take note of how much real estate each window takes up when you look at the surfaces of each wall.
Window panes with only one pane lose the most heat, although a tint can reduce some of that loss. Today, most homes have double-paned windows. By comparison with single-pane counterparts, they provide significant energy savings.
In addition to wood and vinyl frames, aluminum frames are also an improvement. There are also energy-efficient windows available. In other words, they cut down on the amount of sunlight passing through the glass.
Installing an insulating film on your windows is a good option. Similar to plastic bubble wrap, it creates a small air space when you attach it to the inside of the glass.
Again, you won’t experience any dramatic difference with this method, but if you cover all of your windows with enough film, you’ll be able to block some heat while still allowing natural light to enter.
Frequently Asked Questions
1. How long does a window film last?
It is dependent on the type of film, the type of glass, the type of window construction, and the compass direction of the glass, as well as the climate where the building is located, to determine the life of window film. High-quality films have lasted over 25 years in documented cases.
The film manufacturers guarantee their window films for residential and commercial use for a minimum of ten years and a maximum of fifteen years. If you have any questions before or after installing the window film, you can get in touch directly with the manufacturer.
2. Does the self-static no adhesive window film work in cold climates?
You can soften the film using a hairdryer or soak it in warm water if the weather is cold.
3. How can the film adhere well and remove bubbles?
I suggest you spray more soapy water on the window and rinse it again. Make sure you use enough water. The more it flows, the better.
4. What causes the film to peel off?
You must clean the surface thoroughly and make sure that there is no dust on the surface. Apply the film to the window after removing the protection film from the first tier. If not, the film will peel off.
5. Why is the edge of the window film curling up?
Glue is used to adhere the film to the window frame. A small gap (two to three millimeters) should be left between the film and the frame. It may also be difficult to apply the film due to cold weather.
Try blowing the films with a hairdryer or soaking them in warm water to soften them. Holding the hairdryer 1″-2″ (2.5-5cm) away from the film surface set the heat on high and run it over the film.
