Answer: Four feet

When giving dimensions of windows or doors the width is always first followed by the height.

Answer: R Value

Insulation rating values are given an R then a number, for example R11 or R15, the higher the number the more effective the insulation.

8. On a set of electrical plans what would a triangle represent?

Answer: Telephone

On a set of plans there is not enough room to write everything in so they put symbols that represent items on the plans and usually a legend on the front page in case you don't know what a symbol stands for.

9. What is the stud called that is placed at the side of an opening, under a header, to support it?

Answer: Trimmer Stud

The amount of trimmer stud required under each side of a header depends on how big of an opening you have. For an example if I have a four foot by four foot window I would only need one trimmer stud on each side of the header, but if I had an eight foot by four foot window I would need two trimmer studs on each side on the header.

10. On a set of plans if they call for something to be 16oc, what does the oc stand for?

Answer: on center

When a building is engineered the engineer will require different layouts to note this he/she will give you an on center measurement so you know what spacing to place the item.
