  • Conventional Roof Framing: A Code's-Eye View

    When it’s boiled down, there are essentially two standard methods of roof construction, each having some flexibility. We explore both.

     
  • a. Spans are given in feet and inches. 

b. Table is based on a maximum roof-ceiling dead load of 15 psf. 

c. The header [may] be supported by an approved framing anchor attached to the full-height wall stud [...]in lieu of the required jack stud. 

d. The 20 psf ground snow load condition shall apply only when the roof pitch is 9:12 or greater [...] 

e. Building width is measured perpendicular to the ridge. For widths between those shown, spans [may] be interpolated. 

f. The header shall bear on a min. of one jack stud at each end.

  • Working With Roxul Insulation (Subscriber content)

    Choosing insulation for a high-performance home in Northern Vermont requires thought and care. The right choice can make a huge difference in both comfort and cost efficiency.

     
  • When it comes to improving the energy efficiency of a building, lots of attention is paid to insulation R-values, thermal bridges, and air sealing. But dont forget the windows, which account for the biggest energy loss in a high-R wall.

    To Improve the Energy Performance of Walls, Look at Total R-Value (Subscriber content)

    Today’s builders are learning to mitigate thermal bridging by using alternative framing techniques, continuous exterior rigid foam products, or both.

  • To use your own data to find hrs/BF or hrs/SF, divide average hours used for each framing task by total SF or BF of materials used. (BF = thickness x width [in inches] x length [in feet]  12). This table shows figures for tasks associated with framing and sheathing a typical exterior wall.

    How to Calculate Unit Prices for Labor (Subscriber content)

    While unit prices for labor are available from a number of sources, the best source is a company's own job history. This article uses an example of framing an exterior wall to show how to use that data to calculate unit costs for labor based on material quantities.
