Description of contiguity to the wall
One of the most common types of contiguity is called abutment to the wall. The place of the roof adjacent to the wall of the house is designated by the term "abutment to a vertical wall".
The question of the thermal insulation of the room is important. Covering materials are used:
- Soft roofing materials
- Metal plates
- Tiles
There are construction companies offering a variety of solutions in the selection of coating materials and additional aids for standard roof joints. Specialists distinguish additional contiguities to the roof wall:
- top
- lateral
Construction materials for covering contiguities: roofing tile, profiled
There is a traditional abutment, installed in a stroby( size 25/25 mm), located in a brick wall 15 centimeters from the roof surface. It is placed in the profile in the form of a galvanized metal strip. Predominantly use the PS-1 bar. In the strobi is placed a wooden strip, fastened to the dowel, a strip of profile - on self-tapping screws. Diluted cement in the opening. Sealant helps to remove excess air and excess elements in the stem. Now the strip from the profile is applied to the roof surface, to the immediate junction.
The standard technology of abutments is also used when installing a roof joint and wooden walls.
It is important to note that it is not recommended to use a shtrobu in panel houses. According to the building standards, the panel walls are load-bearing, and the cut hole has a negative effect on their strength.
Adhesion from soft tiles: installation of
In the standard scheme, the installation of a joint of a soft roof to the wall is performed with a shroud. Height - 2-5 centimeters from the roofing. It is important to consider the issue of waterproofing. To do this, use an antiseptic segment of a triangular section, not allowing to flow in places of bending.
Before the roofing material is applied, the place on the roof and the abutment site are carefully treated and eliminated excess contaminants, the priming junction is processed. The source of the roof is a soft covering laid on a special bar. Helps to eliminate the course of the valley, it is glued to bitumen( the width of the valley is 1 meter).It is important to fix the junction block with a metal strip( 10-20 centimeters).
Important issue of sealing
To make the junction of tightly sealed a construction strip of corrugated aluminum or lead foil on the basis of glue, a width of 28-30 centimeters and a length of 5 meters. Its use is justified by convenience and high quality. Issued by:
- Wakaflex
- Flex standard
Manufacturers are more than 20 years old, and recommendations meet expectations. Firms know all the nuances that arise when installing junctions, and create a reliable protection against leakage at the place of docking.
The function of the strips is to seal the abutments on the roof, to create reliable straps that do not allow additional moisture to pass through. The material has different color shades. When the temperature changes, they can increase in size, covering the roof surface by half more than the originally occupied space. Can withstand temperatures from -50 degrees to +100 degrees. The beginning of the tape is fixed to the wall with a "Waka" bar with no strobes.
Popular ways and means of contiguity
Adjacencies are built not only to the wall. A similar connection of pipes is a common kind of extension. Such an abutment is carried out with the help of modern elastic corrugated cuffs, which have in their composition temperature-resistant components with silicone. The heat resistance is -50 degrees and 350 degrees with a plus sign. The components have an adhesive basis. Its properties:
- quickly solidifies
- ability to withstand strong temperature loads
- ease of use
- durability
- high tightness
As a substitute for cuffs, use adhesive strips of corrugated metal - "Waaflex".The only observation is that the upper strip is fixed independently on the pipe of abutment with the aid of a clamp made of metal.
Note! Today, not only abutments of walls and pipes are performed. The construction techniques of a similar combination of mansard windows, gable pipes and ventilation have been developed.
