building up a house in series of platforms (layers)
|
|
|
Header |
beam that carries loads around windows and doors
|
|
|
King Stud |
stud to left or right of opening thats continuous |
|
|
Sole Plate |

|
|
What are the differences between balloon and platform framing? |
Balloon = full length studs that run continuously from foundation to roof Platform = building up a house in a series of layers
|
|
|
Advantages and Disadvantages of Balloon Framing |
Advantages: framing could be completed faster and could be completed by a single person Disadvantage: Hollow spaces between studs allowed for fire to spread rapidly |
|
|
Advantages and Disadvantages to Platform Framing |
Advantages: short, easily handled lengths of lumber, vertical hollow spaces are automatically firestopped at each floor Disadvantage: large amount of vertical shrinkage in the frame as the excess moisture dries from the wood |
|
|
Spacing of Rafters and Trusses |
16-24 inches |
|
|
Building Felts |
Roofing paper that's been impregnated with asphalt |
|
|
Flashing |
Sheet materials used to stitch together all protective memberings |
|
|
Galvanized |
Coating with Zinc |
|
|
Roof Pitch for Steep Roofs |
Above 4 and 12 more pitch = more materials |
|
|
Low-Slope Roofs |
Under 4-12 more economical when it comes to materials |
|
|
Why does sheathing have to be spaced? |
so wood sheathing can dry out |
|
|
Sheathing |
made of plywood or OSB Surface where we put all of our protective memberings has to be rated for exposure |
|
|
Difference between Wood Shingles and Shakes |

|
|
Fluid applied Membranes |
Liquid poured or sprayed on that sets into roof form |
|
|
Roofing and Building Codes |
Class A - Severe fire exposure (concrete tiles, ceramic, slate) Class B - Moderate fire exposure (Built up roof system, sheet metal) Class C - Light fire exposure (Wood shingles, shakes) |
