![]() ![]() The other reason proper purlin spacing is important is because it ensures proper ventilation. The reason for this is that different types of roofing material requires different sized spacers in order to properly support it. Purlin spacing is important because it determines whether or not you are using the right purlin board. The overlap value is calculated automatically depending on the slope angle.See Purlin Spacers Why Purlin Spacing is Important The number of whole rolls of steam-hydro insulation, taking into account overlap. Number of rolls of steam-waterproofing with overlap.The total number of rows of crates and counter-crates according to the specified dimensions for the entire roof Number of rows of crates and counter-crates.The total number of rafters at a given step for the entire rafter system. The calculated cross-section of the rafters, taking into account the selected parameters and loads. ![]() The margin of safety of a suitable section of the rafters, depending on the minimum section. The length of the rafters from the ridge to the base of the ramp Includes the weight of roofing material, crates, counter-crates, rafters and insulation, as well as snow and wind load in the peak, taking into account the slope angle Roof weight taking into account climatic loads.By default, the bulk density of lumber is 600 kg/m3, and the density of insulation is 35 kg/m3 Includes the weight of roofing material, crates, counter-crates, rafters and insulation. Load per 1 square meter of the truss system, taking into account snow, wind load, as well as taking into account the slope angle, the weight of the roofing material, the weight of the crate, counter-crate, rafters and insulation The total area of the entire roof surface, taking into account the length of the overhang. To increase or decrease, change the parameters of the base width or height The program will also tell you whether this angle is suitable for the selected General information on the results of calculations The following is a complete list of calculations performed with a brief description of each When filling in the data, pay attention to the additional information with the Additional information In this case, it is necessary to take into account the increased snow loads on the roof and Various slope angles are applicable to this type of roof, but most often It can be both attic andįor this roof, almost all popular types of roofing, under-roofing are applicable It is used for garages, outbuildings and other non-residential premises. This type of roof is quite popular and mostly The single-pitched roof is the simplest among other types of roofs and economical in terms ofĬonsumption of materials and works, as it has only one ramp. The calculation is accompanied by drawings in different projections, and a drawing of the rafters with the dimensions of the lower saw. It is possible to calculate a flat roof according to the specified parameters. Roofing materials such as ceramic, cement-sand, bitumen and metal tiles, The calculations take into account all popular Rafters, the number of crates, as well as the volume of necessary materials. The online single-pitched roof calculator is designed to calculate the slope angle, quantity and size Please report any errors found by feedback by copying the link to the calculation. Information on the purpose of the calculator Number of rolls of steam-waterproofing with overlap 200 mm The number of fasteners is 8 pieces per 1m2 The number of roof battens boards in length 6 meters The distance between the rows of the roof battens The minimum size of the rafters at the spacing 600 mm Roof weight taking into account climatic loads ![]() The angle of inclination is suitable for the selected material. ![]()
