How to choose a type of attic window
The transmitted structures that are intended for use in attic rooms consist of the following parts: frame (the same profile), double -glazed windows, ventilation device, opening system and a number of additional accessories.
Both plastic and wooden attic windows are made. They are environmentally friendly and with a great appearance. The material for their manufacture is used different, but, despite this, there are a number of mandatory characteristics: double -glazed windows must be frost -resistant, strong and durable.
In order for the windows to be frost-resistant, many manufacturers use gas Argon as an internal filler. These windows are often equipped with double -glazed windows, which are cleaned themselves, splitting mud particles under the influence of rain and sunlight.
