The height of the installation should provide the ability to control the sash with the handle, its average value is 80-130 cm.

Installing a window opening over the radiator will eliminate the appearance of ice.

The angle of slope of the slopes also affects the placement of the windows, on the flat roof they are located higher.

Installation

Before you install a roof window, you need to mark up the space for it. It is produced from inside the premises. 3 cm from the rafters, the lower limit of the window is planned, an additional 9 cm is deposited for a roof with a high profile and 6 cm for a flat one. Noting the upper limit corresponding to the height of the model, mark up another 7 cm. The waterproofing sheet is cut with a margin of 20 cm and wrapped inside. If the roofing is already installed, it must be cut off, the crate is also removed.

In some cases, you can install as follows:

A bar oriented horizontally is nailed in the lower part of the opening, in the upper part - a bar parallel to the crate.

A factory drainage gutter for sediment discharge is mounted above the upper plank, it is installed at a slight angle. If such an element is not included, its role can be performed by the construction of a waterproofing strip.

In order not to damage the glass and fittings during the installation process, it is recommended to remove the sash. Next, the frame is mounted according to the manufacturer's instructions. Brackets are included in the drilled holes. A strip of mineral wool is attached to the upper part of the frame with a stapler for insulation. A strip of insulation is also attached to the assembly bar at the bottom of the structure. The frame is installed in the opening and is fastened to the corners with self-tapping screws. The upper fastener is not fully tightened, leaving room for alignment.

Now the sash returns to its place and checks the uniformity of the gap on all sides of the fit. Making sure that the sash is properly installed, we perform a secure fastening of the screws in the upper part, and remove the glass again. The left parts of the waterproofing are fastened under the window seal with staples; a waterproof apron unfolds around the window, the top of which is inserted under the gutter.
