The purpose of the outer tump is the removal of water from the window and the protection of the walls from atmospheric precipitation. Without them, the installation of the window is considered unfinished. Salves can be made at least from titanium, it all depends on the possibility of the customer.
Choosing a fiber material
Most often, foals are made of galvanized sheet, without additional coating. The disadvantage is noise during the rain. Plastic absorb sound, harmonize with plastic windows, looks beautifully. But from sunlight and frost, over time, lose their appeal. Aluminum differ simplicity of manufacture, just bend at their discretion and paint. However, the workpieces from this material are very expensive. Polyester sals are obtained from ordinary galvanized billets by applying polyester coating. It is cheaper than aluminum and have a beautiful appearance.
Design of sings
Over the installation on a regular place should go beyond the walls of 30-50 mm. The product has a bend for fastening to the window frame. On the sides and below should also be bending for water flow, the lower element can be with a drip. Length of 3-4 cm is wider than the window opening so that water from the walls and windows is guaranteed to flow outward, and not in the room.
Installation of low tide under the window frame
Salves are installed after mounting the window when the gaps are filled with the mounting foam, before finishing the outer slopes. Elements are recommended to be installed under the window, so check the presence of a special profile in the frame for fastening products. Work immediately after installing the plastic window, on the same day.
Production "Bed"
Cut the excess foam material from the outside of the window. Make a bed "bed" under the sow. If the gaps are only a few millimeters, use the mounting foam. To eliminate large gaps, first use cement mortar. In the case when the slopes are set up much lower than the frame, use coaching profiles that increase waterproofing.
Fastening
Install the sill on the window sill so that the edges are included in the slope to 3-4 cm. Ensure the slope of discovery by 10-20 degrees for a good water drain. Slide the pan in the side of the window, press well and fix the load from above so that the foam does not squeeze it. Fasten the tump to special sites on the window frame by self-draws or rivets. Fasteners are placed in a step of 20-30 cm. Seal the ends of the sifts into the form. Get out the grooves of walls with a special solution on an acrylic basis. Inspect the windowsill in the area of \u200b\u200bpopular. Fill all the slots of the mounting foam.
Fastening
Another optional installation option is a mount to the windows frame. It is used in non-standard situations when the lower part of the frame is recessed into the windowsill, for example, with incorrect measurement of the window. In this case, the slope is attached not to specially intended for these purposes, but to the windows frame.
Features of fastening molding to the frame:
- It is forbidden to close drainage holes.
- Before installing the slope to the curved part from the window, apply a silicone layer.
- Use screws 4.2 × 13 for fastening, screw the fastener after 200 mm.
- It is forbidden to use screws longer than 13 mm, otherwise they will penetrate the windows frame chamber.
- Screws put on sealant.
The installation of slopes is referred to responsible work, poor-quality installation is difficult to correct. Typical errors include incorrectly selected angle of inclination of the element and poor waterproofing material. To eliminate such errors, you will need to dismantle the tide, which leads to damage to the side walls of the window.
