Metal frames made of metal, aluminum and iron, although very strong, special maintenance method almost does not require repair But the heat is expelled very quickly, which makes the metal a very weak insulating material. In the United States, the value U is displayed to indicate the amount of heat that can pass through a window. To reduce heat flow and U coefficient, metal frames should have thermal failure and an insulating plastic strip should be placed between the inside and outside of the frame.The insulation of iron windows will reduce heat transfer from one side of the window to the other .
Use of double and triple glazed windows
The first problem with the old iron windows is their glass model , which is single - glass . In the first step, try to double or triple glazing the glass .
First of all , you 'd better know how the glass works . Double glazing with two panels and triple glazing with three panels .Insulated windows are energy-saving windows that help you control the amount of heat inside your home without wasting energy. The space between each glass is usually filled with krypton, xenon or argon gas to fill this space and keep the heat in the house.
Double and triple glazed windows have low-emission coatings,This means that their glass has a thin metal coating that can significantly improve their thermal insulation performance. In another area where low-electron layers are used, there are thermal barriers, some of which reduce the heat loss due to radiation in areas with thermal insulation.
To reduce heat flow and U coefficient, metal frames should have an insulating plastic profile located between the inside and outside of the frame. These profiles are also called thermal breakers and are made of glass fiber reinforced polyamide 66. It should be noted that the glass fiber ratio is 25% and the materials used for this insulation rod are distinct due to the low thermal conductivity which is equal to 0.30 W / mK and good mechanical properties even at higher temperatures. An unheated frame of aluminum window has a heat transfer coefficient of Uf6.8 W / m2K, and if this system with thermal insulation characteristics with a width of 42 mm is thermally separated, the heat transfer coefficient can be reduced to 1.3 W / m2K.
Most modern windows use glass doors to maintain distance between their windows and insulation , many of which are made of aluminum , which is , of course , a conductive material .There is a better option for higher insulation performance, and that is special plastic spacers, which are more commonly known as thermal spacers.
Another method of insulating the metal windows is the use of inert gas gases , krypton , or other inert gases . Most windows use inert argon gas because it is cheaper, but the shorter the distance between the glasses, the better krypton inert gas will be.However, using inert gas krypton, increasing or decreasing the space will cause a decrease in performance
The most common problems in these types of windows are the opening of their frames , which is the cause of the catch cold and noise . Sealing of window frames can be done using special rubbers made of EPDM and also available in various thicknesses in the market. The rubber makes you comfortable for a long time to cover the insulation of iron windows .
EPDM is an artificial rubber that is widely used due to excellent resistance to environmental factors such as ozone , ultraviolet rays and air . EPDM is commonly used in the automotive and construction industries for insulation . Common applications of EPDM include insulating iron windows, doors, glass, waterproof sheets, and electrical washers. However, EPDM is a head and neck lower when faced with its closest competitor, the silicone elastomer. Compared to silicon, EPDM has lower resistance at higher temperatures because it can only reach a maximum temperature of 130 ° C (266 ° F).
1. Use sealing strips to insulate iron windows
These tapes , found in every home , are a cheap way to seal the doors and windows at your house . There are three main types of air tapes , V type and foam . Air compression tapes are the most durable type for temporary insulation of doors and windows. V-shaped air strips are placed next to the door or window stopper and provide an insulation or barrier to prevent cold air from entering. The foam also adheres to the desired place in different sizes with the adhesive on the back and prevents the entry of cold air and the exit of hot air for a while.
2. Use plastic or cellophane to insulate iron windows
One of the urgent methods for the insulation of metal windows is that you use the rubber or the cellophane round the window frame , using a gentle breeze from the dryer or the cellophane to fit the window properly for the window .
3. Use cotton and glue to insulate iron windows
It may seem strange, but these methods should be used in emergencies. You can separate some fabric or cotton according to the dimensions of the window and apply glue to it, or if you do not have liquid glue, stick these cotton swabs around the window frame and fasten them with tape. You can then use scraps of paper to cover small crevices.
Insulation of houses has been around since the time of our ancestors and is done in various ways. Today, due to the development of amenities, less iron and aluminum frames are used for windows. If you use iron windows at home, these methods will definitely work for you. We hope you find this article useful. Please leave us your comments and suggestions
