- pine (XRP)

200cm, 270cm, 350cm.
The selection of the rafter length depends on:
When using a narrower rafter (18mm), on the outside, the windows are connected with a special flashing EZV-A 18 DUO for corrugated roofing materials or ESV18 DUO for flat roofing materials. It is a specially prepared solution to be used with the auxiliary rafter 18 mm. In the top and bottom section, the DUO flashing has a common element connecting the two windows together. .
- height of the window with which the rafter is to be installed,
- structure of the roof (desire to obtain the optimal shape of the lining and proper air circulation after installing windows in conjunction with the rafter).
In the case of the auxiliary rafter 100mm thick, there are used standard flashing for combinations, e.g.: KZV-1-P or KZV-3-P.
The window combination with the auxiliary rafter, (18mm, 100mm), makes it possible to insulate around the windows frame with the use of an insulation set XDP or sheep wool tress XWW.
