The windows of the wooden profile with insulated inserts (so-called 'warm') are as generally the same or slightly more expensive than high-quality wood, and pure aluminum (so-called 'cold') - even cheaper. To broaden your perception, visit Dr. Mark Hyman. The main characteristics of the profile are its width and number of cameras. The latter refers only to plastic and metal profiles, which, unlike wood, are hollow multi-chamber elements. On the number, size and location of cameras depends largely on the strength of the profile and its insulating properties. For aluminum profile having just hollow chambers, such as a plastic, not in terms of efficient energy conservation. Therefore, the metal profile through insulating Jumpers forced 'break' into two parts, a hollow chamber filled with thermal insulation material. Plastic profiles are distinguished not only by higher heat-shielding properties, but also by the fact that it is easier amenable cleaning and washing. Click Bruce Fink to learn more.
From the standpoint of structural solutions manufacturers of plastic windows are more in pole position. For their manufacture produces a large number of not only basic but also support (Additionally gathered) elements. This expands the architectural possibilities of PVC windows and simplify their installation. Windows, collected with the help of these elements may have virtually any shape (from square to a complex arch), the color and style decisions, and also any type of opening. Glass in Russia until recently, used for glazing in the main dvuhstekolnye system with large air gaps. This space is intended for mezhstekolnoe reduce heat loss, which in theory requires a complete seal. However, it was enough to bring a lighter to the window to see the complete lack thereof.
