Transmission Heat Loss through Building Elements - Heat loss through common building elements due to transmission, R-values and U-values - imperial and SI units. This is the complete guide to framing any gable, Dutch, Tudor, California, gambrel, shed or gazebo roof - including irregular roofs that can stump even.A SketchUp model helps clarify how various rafters and framing components are assembled in an 'off angle' hip and valley configuration. The biggest issue really seems to be that Home and Interior Designers havent widely adopted Revit yet. I could model different roof lines and try out different framing concepts all day long with this. Slope - Degree, Gradient and Grade Calculator - Convert slopes pitch between degrees, gradients and grades. Explore framing complexities that result when roofs of two different pitches intersect. The Rafter Framing Tool was, very quick and easy as a starting point that could be modified.The Rafter Youre After: Using SketchUp to Draw Roof Framing. Roofing Materials - Weights - Weight calculator for roofing materials. Roof framing can be one of the most challenging and confusing parts of building a house.

Rainfall on Roofs and Gutter Slopes - Draining of roof areas and recommended gutter slopes.Rainfall Draining of Roof Areas and Vertical Downspouts - Capacities of vertical downspouts when draining roof areas in rainfall.Moisture Transport through Walls and Roofs - Moisture will flow through a building wall or roof if the vapor partial pressure is higher on one of the sides.With the saw bevel angle set to 45°, cutting hips and creepers at the plumb cut angle will produce correct side angles. Horizontal Roof Rafters - Maximum Spans - Douglas Fir in horizontal roof rafters and maximum spans. Hip roof framing rafter cut angle template diagram If using a Circular Saw or Compound Miter saw, set the saw bevel angle to 45° to obtain correct Creeper and Hip side angles.Chimneys - Roof Termination - Chimneys and single wall vents roof termination.Building Tolerances - Typical tolerances for floors, walls, columns and more.Miscellaneous - Engineering related topics like Beaufort Wind Scale, CE-marking, drawing standards and more.Slope/Inclination Degree, Gradient and Grade Calculator In metric countries it is common to use degrees or 10 or 100 as denominator. In the United States, slope is typically given in inches per 1 foot or as a ratio of inches per 12 inches and is often referred to with units of 'pitch'. Roof slope is the ratio between the vertical rise and the horizontal run: The Gable Height of a roof with 30 feet run and vertical rice 6 inches per foot, can be calculated as VR = vertical rise (in/ft, cm/m) Example - Gable Height
