While it is important to buy windows from a reputed windows company, the quality of the windows too is very important factor in their selection. The window is not like a put in a boathouse in the winter, as the yacht. Manufacturers of the best cruising yachts that are worth millions of dollars just provide a guarantee on its fiberglass body for not more than 10 years, provided that it swims at a temperature of not less than -1.8 degrees (freezing temperature of ocean water), otherwise the guarantee is removed. For the average apartment window this time period is not enough. De-lamination occurs by spilling of a synthetic resin called binder. Manufacturers are working on this problem, but still they far from a complete solution. So FBK window appeared on the market recently, and is expensive and not very durable. FBK deficiencies deprived composite material based on carbon – carbon fiber or carbon fiber. But prices have kept astronomical, and carboxylic window is possible only in a form of a fad rich, custom-made designs.
Metal- Plastic windows is a good example of how a minus by minus gives plus. The strength and flexibility of PVC with fever slumping: when higher than 60 it becomes unusable as a structural material, and even at 80 begins to soften. The elasticity of PVC is also low. Edison once said: “Everybody knows that this is impossible. Then he is an ignoramus who does not know this. He makes the invention “. Probably, plastic windows and were born this way. Features thermal strength solid PVC and metal-plastic Features thermal strength solid PVC and metal-plastic A fool, inside their poor PVC pipe firmly insert a tube of aluminum wrong. And what happens? The thermal coefficient of aluminum is much higher than of PVC, it will inflate the plastic from within, and the whole structure will keep the strength to temperatures above 60.
But in combination with PVC aluminum proved a godsend for window profiles: the combination of deficiencies of both gave undeniable merits. Fiber Composites Reinforced profile are also called as fiberglass or fiberglass composite (FBC). This was a tricky name to hide the good old fiberglass. FCO on all counts is even better and exclusive than wood. It has virtually no heat conducting, But it as a huge drawback: it exfoliates from the weather. If there is more heat, then the plastic begins to unravel, but it is not important: at such temperatures is not generally reached. In addition, mutual mechanical stress greatly increase the elasticity of the assembly. Place a metal ruler on the two pencil – it will sag under its own weight to the counter top. And try to squeeze her two books so that arched up – there is no purpose and giving until the book is not moved. In the cold effect of the mechanical interaction of the materials will be gone, but the PVC when cooled rapidly gaining strength and elasticity, just as increasing the thermal conductivity.
