When choosing a window for residential and commercial buildings, the main concern is achieving a regulations compliance certificate. This will probably involve glazing and height requirements; for example, generally an opening window is required to be less than 24 inches (610 mm) above the finished floor. You will need to get a certificate to prove that you have complied with the regulations. Here are some points to consider:Get more news about Architectural Casement Window,you can vist our website!

What are the regulations?
Windows must meet the required energy efficiency in terms of thermal transmission. This is measured by the rate of heat transfer through a product: its U-value.
Windows must meet the glazing protection against impact requirement.
What is the window opening height requirement?
Replacement windows must comply with thermal performance standards.
Structural requirements for mullions must pass an obligatory test or calculations.
Commercial buildings: The owner of the property or land is usually responsible for complying with the relevant planning rules and building regulations.
The project, whether a house or commercial building, will point you toward the right path of choosing the ideal window so we will first discuss these two situations with their respective regulations. We will then discuss the "why" behind the different glazing options and define the various opening systems.The frame is equally important so we will highlight the most common materials used. There are also a number of technical characteristics to consider, along with other traits.

Glazing requirements will alter depending on your project and location. When you know the regulations, you will choose between four types: single glazed, double glazed, triple glazed and quadruple glazed. We mentioned the U value requirement earlier. A low U value means the window achieves an efficient temperature retention; the lower, the better. In a cold climate, a good U value for a window is between 0.17 and 0.39. U Values are measured in W/m2K.
