Glass coated with colored or reflective film has been widely used on Windows in commercial and industrial buildings for several years, as a means of reducing solar energy to absorb heat in warm, sunny days, and eliminate objectionable glare without cutting off the field of vision.
This protective coating not only greatly reduces the indoor temperature, thus greatly reducing the cost of cooling and air conditioning, but also prevents fading of carpets, curtains and other indoor furniture.
While some manufacturers produce special types of glass that have been coated with reflective film, the vast majority of Windows with this protection are actually made up of plain clear window glass, A relatively new metal transparent plastic film has been applied to these glass (
Inside surface of glass).
This film can be applied to almost any type of existing glass, once applied more or less permanent
Although it can fall off quickly if needed.
No special maintenance required-
Windows are cleaned in the usual way with a common cleaning solution.
However, grinding cleaners must be avoided and bristles that may scratch the film must not be used.
Until recently, various producers of these reflective solar control and glare control films were sold only through authorized distributors/installers who are primarily interested in large commercial installations.
However, as more homeowners begin to show interest in these films (
Mainly due to their value in cutting air-conditioning and electricity bills)
The distribution pattern began to change.
Some dealers/installers are now willing to install solar control films on windows of private homes (
By looking under "glass coating and coloring" they can be found in the yellow pages of the local phone book)
More interested for many homeowners and apartment residents
Producers have started selling several other versions specifically designed for their own installations.
These are different from professionally installed products because they are made of thinner, easier-to-handle paper, and they have an optical and transparent adhesive backing, before the film is applied, activate by spraying water on the glass.
Like the professionally installed version, these plastic window films also offer several other advantages
In addition to reducing cooling costs and eliminating glare.
They also help to reduce heating costs during the winter months as they reflect the furnace heat back into the room during the heating season, with a side benefit of privacy during the day.
While one can easily see from the inside, from the outside a passer-by will only see what looks like a large mirror and will not allow him to see anything inside. (
At night, however, the opposite is true;
Because its interior is brighter than the exterior, the window will have a mirror-like look from the interior, and the outside window can be seen very clearly.
It doesn't seem to bother most people, because in any case they pull blinds or low shades after dark).
Tests show that in rooms without air conditioning, these reflective films can reduce the indoor temperature by 10 to 15 degrees on hot days, and can reduce the cost of air conditioning in large window rooms by up to 50.
The film consists of a "sandwich" made of transparent polyester with a thin layer of aluminum evaporation coating in the middle that reduces glare by up to 50 or more, although these numbers will vary depending on the brand, color, and type, depending on their design purpose.
At present, at least two different companies distribute this material to consumers nationwide.
A magic stick called ReflectoShield, produced by 64 new industrial Avenue Madico, Woburn, Volkswagen. 01801.
Another movie called Scottish sunshine control, produced by St. 3m Center 3 m. Paul, Minn. 55101.
Each company manufactures materials in rolls of various widths and lengths and in several different colors (
Most popular in gray).
Madico is currently marketing their own products through department stores and home centers in many communities, but as of now, 3 m is only marketed through Sears Roebuck and their own dealerships/installers
The price of Diy materials is usually between 90 cents and $1 per square foot, while the price of professionally installed materials is $1. 80 to $1.
90 per square foot
While it is not particularly difficult to install this material and special tools or materials are not required, it does take time and patience.
The film must be handled carefully and not wrinkled, but the most time consuming thing is that the glass must be cleaned very carefully in advance.
Instructions provided suggest first spray the glass with a cleaner and rinse it clean, then scrape every square inch of the glass with a blade, to ensure that no paint, dirt, putty, or other alien meteor spots create bubbles or blisters after the film is applied).
After that it is better to clean the glass again and then dry it thoroughly with a paper towel --
Especially at the edges and corners.
After cutting a film into an approximate size, the glass is thoroughly soaked by spraying clear water with a spray bottle.
Peel off the back of the paper and then smooth the film on the wet glass with the palm of your hand.
After the film is in place, more water is sprayed on the film, after which the film is squeezed slowly and firmly to eliminate all wrinkles and bubbles and squeeze out excess water from below.
The trouble place can be pulled down, re-breathing, and then squeezed back again.
The final step of the ad is to trim the excess parts of the edges with the new razor blade.
A little extra attention is required here to avoid cutting into wood trim or paint, resulting in spots that may appear in March.
Working slowly and moistening again, if necessary, usually solves the problem of cans.
In general, the movie will still be a bit hazy after it is finished, but with the excess water trapped under the movie vaporizing, it will disappear in a few days.
One interesting thing about Madico's magic wand is that it can be reused. That is—
It can be stripped easily and then re-applied at any time (
As many as 30 times according to manufacturers).
So it can be taken away when moving
Or, when no glare reduction or sun reflection mass is required, it can even be removed in a few months and then re-applied in the next season.
