Installing a window sill

Proper installation of the sill is important because it is an element that the operation is exposed to various influences and pressures. This sunlight and temperature fluctuations at the window, and moisture in the form of condensate, mechanical loads, when we get him down or use as a shelf or table. All this imposes certain conditions for the installation of the sill.

The first thing that should be started, it froze the required size of the window sill. The length should be longer than the window itself, so that the edges were sill in the wall. The width of the sill depends on the depth of the window opening, plus 5 cm edition of the Wall. Since under the window, usually located radiator is not recommended to release the sill greater than 5 centimeters, it will prevent the movement of warm air to the window. But sometimes you need something to sill acted out of the wall is much greater in this case, the sill must be cut through the holes and to equip them with, for example ventilation grilles, through which will pass the warm air from the radiator. So is this version of the suit when the radiator is hidden under a covering of the wall.
The next stage, site preparation for the windowsill. The right thing to install window sill when installed and blow the foam box, but do not tailor all slopes, in the case when the window slopes are older, if necessary, must make a place in the walls, which will include the edge of the sill. If the wall is sheathed with gypsum plasterboard, the windowsill is best to set the stage when harvested, but not edged plasterboard framework of the profiles. The design of cladding must be provided in profile (usually UD), at the appropriate level, which will serve as the window sill. With regard to the window, then plastic windows from the bottom should be a special profile, which will abut the window sill, and the wooden window sill for a special quarter. Distance from the window to the bottom of the window opening, which will form the sill must be greater than the thickness of the sill at least 2 cm, which, it could be blow the foam. Wall must be clean from dust and various debris. After that, try on the window sill in place and to make the necessary gash.
When he prepared the window sill and place for it, with the help of temporary linings (say made of wood), we expose the sill in place, as it should be. That is, horizontally in the window length and with a slight bias towards the premises, it is necessary that-be if there was water on the window sill (we assume the condensate from the window), it trickled down and there was no puddle. Deviation of about 3-5 mm. by 20 cm wide sill. Sill have to go to the window, but are not limited to it.
When thus exposed the window sill, you can start blowing foam space underneath. It is worth remembering that the foam expands and can simply raise the window sill of his seat, something it had not happened, you can make temporary braces to the upper slope or put something heavy on top.
If the wall is sheathed with gypsum plasterboard, the sill should be bolted from the bottom screws to the profile, do not forget to pick up the screw length, something would have to pierce through the sill.

When you install a window sill which performs much of the wall, 15 cm or more, you must use brackets, simply put corners, which is attached to the wall and fasten them to the windowsill.
When the foam is completely dry, preferably the next day, you can pull the temporary backing up and blow out the emptiness of their foam. So our window sill must lie completely in the foam that will reliably protect from cold and frost on the street and provide stability and strength.
And finally, what is not to forget, for laminated and plastic window sills, it is put on the edges of plastic plugs, if the sill of the CPD, it is better to put caps on silicon, something would be there did not get wet. Well, then you can proceed to finish slopes and the entire wall.
