Installation Guide roofing

Sheets of metal are available on pre-stated dimensions, which are established as a result of a careful measurement of roof slopes. Determining the value of a base size - from the eaves to the ridge. If measurement is necessary to consider that the bottom sheet metal overhang should be about 40 mm. Given the standard useful width 1100 mm sheet metal, one can calculate the required number of them. With a length of slopes of more than 7,5 m sheets preferably split into two or more pieces with overlap of 150 mm. Smooth the roof before installation to check the geometric dimensions of the roof. Diagonal of the rectangular chutes should be of equal value. With a small difference in the size of the defect can be corrected by the individual elements. The minimum allowable angle of the roof of the device metalllocherepitsy 14 degrees. If the angle of slope less than 14 degrees then the overlapping sheets of metal made in two waves. 2. Vapor and waterproofing on the lower surface of the cold metal condenses moisture in the warm air, understand from the interior. This leads to the formation of mold, moisture rafters and sheathing, frost damage to the roof and interior. To combat these phenomena should be: to carry insulated interior of the roof to protect the insulation from the bottom of the moisture vapor barrier film inside the house, to protect the insulation on top of waterproofing film, to ensure adequate ventilation. Cloth vapor barrier film is placed under teploizolyatsionnyymaterial and tightly connect the overlapped with the sizing tape. For added protection, insulation from external moisture entering the rafters laid waterproofing material. Layers of waterproofing film deploys horizontally from the eave to the ridge with overlap of 150 mm and slack in the film between the rafters of about 20 mm. Side of the film with a colored stripe on the edge should be facing outward. Flip the tape is not allowed. To ventilate the interior space between the film and the insulation needed to keep the ventilation gap of at least 40 mm, and carpet underlay waterproof plenkidolzhen not reach the ridge about 40 mm. Waterproof film. Seal skate with perforation. Additional boards lathing in the apex. Ventilation gap in the waterproof film. Airing - a fundamental condition for the robust design of the roof and foundation under the roof. For ventilation is necessary to ensure unimpeded passage of air flow from the eaves to the ridge. Ventilation is carried out through: the gap between the Cornice strip plank and metal, especially left by air gaps of 50 mm binder overhang roof ventilation gap between the waterproofing film and skate, skate perforation in the gasket. 3. According to the rafters purlins laid waterproofing material nailed decaying blocks 25 x 50 mm, and to them antiseptirovannye boards lathing 32 x 100 mm increments between 350 (400) mm, corresponding to step metal (350 mm - Profile Monterrey, 400 mm - profile "Max"). Lower board sheathing must be thicker than about 17 mm and the distance between the start of the first and middle of the second board sheathing shall be 300 (350) mm. If the distance between the rafters above 1000 mm, sheathing boards must take thicker. To strap ridge was well established, under it on both sides nailed to two additional boards. These boards are covered with a strip of waterproofing material and cover the ventilation slot in waterproof film. 4. Profile Cutting Profiles can be cut: electric Nibblers, jigsaw, circular saw with carbide teeth, scissors, hand to the metal, a hacksaw with fine teeth. Prohibited cutting abrasive wheel, as hot chips, falling on the plastic cover burn it, and this leads to accelerated corrosion in places cut. 5. Setting the profile before installing the profile of the roof overhang is nailed curtain rail. In appropriate places are set lower valley. Metal attached to the boards lathing screws length 29 - 38 mm, for screw-in which you want to have a drill with reverse, brace or other similar tool, and Sockets 8 mm. Mounting usually begins with a right lower roof plate, fixed in the upper right corner of the single self-tapping: fit 2-leaf, fastened together with screws to the top of the waves lap, received exactly the bottom edge is aligned strictly along the ledge with the emission of 40 mm, after which the sheets are permanently secured. As an alternative, we recommend the following method of fastening: fasten sheets with screws in a staggered manner through a single wave. Junction of upper and lower sheet is fixed with screws through the wave. Screws are placed in the trough of the wave (in contrast to the slate). Side laps of sheets held together by screws on top of each wave. Number of screws 6.8 pc. on the square meter. After installing the sheets between the ridge and metal seal is placed with the provisional release of vent holes, then ridge screws 4.8 x 80 c 300 mm (a wave) is mounted horse. The ends metallocherepichnogo skate close to the screw caps. In the valley above ground installation installed decorative exterior valley, and at the ends of the roof - wind boards, which are fastened with screws. If at the end face of the roof, cut metal fell on the lower bend of the profile, the edge of the sheet to bend about 30 mm, to prevent water and snow. To avoid sliding of snow over the entrance to the building at a distance of about 650 mm from the cornice ridge screws mounted snow barrier. Attention! Move on the metal should be in the shoes with soft soles, advancing to the deflection of the wave field crates. 6. Storage Stack of metal sheets of metal in their original packaging must be placed on the flat place on the boards of a thickness of 20 cm in increments of 0.5 m. The sheet must shift the rails if the metal will be stored in a rack over 1 month.
