Plastic steel windows. Although its name with the word "steel", but it is actually a plastic. Its main advantage is the beautiful appearance, low price, but he has a lot of shortcomings, poor thermal and acoustic insulation, easy to aging, and therefore gradually eliminated in the market. General family sealing balcony, on the one hand, can increase the indoor area, on the other hand is to wind and rain, sound insulation and heat insulation. You can use broken bridge aluminum and color steel to compare, which material is more suitable for sealing the balcony.
Economic, not what you want, is to see your home surroundings to decide, if your home by the side of the road or around the often square dancing, must be broken bridge aluminum, and vice versa do not have to, the general aluminum windows and doors on the line balcony is the place where we daily sun clothes in the renovation, some people will choose to make the balcony into a closed balcony, closed balcony has many benefits, you can protect from the wind and rain, to block the external Dust, to create a peaceful living environment, the current closed balcony mainly aluminum alloy doors and windows and broken bridge aluminum doors and windows of two materials broken bridge aluminum is the scientific name of the broken bridge aluminum alloy doors and windows, compared to ordinary aluminum alloy doors and windows, broken bridge aluminum thermal insulation and energy-saving effect is better, the so-called broken bridge above is in the middle of the aluminum alloy with plastic strips and other materials will be separated, and then two aluminum alloys are connected to the series.
Economic point, choose the ordinary aluminum alloy, but to use double-glazed, do the general brand is also quite good, I believe that since you asked the question, the heart must have the relative impression of these two products. I guess you should be more inclined to choose color steel, because more affordable, but because I know that the effect of broken bridge aluminum is better, so it is difficult. This is in fact no need to question, to start from the temporary economic point of view, then it must be color steel tile is cheaper, the choice of color steel tile is certainly to sandwich plate-based, can not be veneer color steel balcony, because it is not at all suitable for commercial housing balcony closed. The third is safer, for the family has children, sealed balcony children entertainment when adults also rest assured. The fourth is that if you do not seal the balcony, often wind and sun, the balcony is dusty everywhere, cleaning is not convenient.
