For all prehung units we REQUIRE that you provide us with your rough opening size. We will build the unit to fit the rough opening size that is provided. If this is for new construction, we normally add 2" to the height of the door and a total of 2" to the width of the door for a rough opening. This allows for the thickness of the jamb and leaves an extra 1/2? in width and height to square the unit.

For single doors, as a general rule, add 2" in width and 2-1/2" in height to the nominal door size for single doors. For instance, a standard 3/0 x 6/8 door would require a 38" x 82-1/2" rough opening. Pairs would require twice the nominal door width plus 2" as well as an additional 1/2" if there is an astragal ( between them. For example, a standard pair of 3/0 x 6/8 doors with an astragal would require a 74-1/2" x 82-1/2" rough opening. See similar questions...

For standard size new construction windows, usually 1 " under the nominal size of the window, which will allow 1/4" clearance all around. For example, for a 4030 XO window, make the RO 47" X 35". If you order a custom sized (heel dimension must be stated) window, the window will be the heel dimension ordered, so you will need to make the rough opening that size PLUS whatever clearance you wish, usually 1/4" all around.

Determining the jamb width for a prehung door can be tricky. For most interior applications it is simply a matter of measuring the overall wall thickness. For instance, a standard wall constructed with 2 x 4 studs and 1/2" sheetrock on both sides would have a wall thickness of 4-9/16", that is 3-9/16" (the net width of the 2 x 4 stud) plus 1" (1/2" sheetrock times 2 sides).

The first step is to determine how much lumber you’ll dry in a year. Then figure your average drying time for each of the species you’ll be drying, and you can calculate the size kiln you need from there. For example: you need to dry 500,000 board feet of oak per year. Fresh off the saw, oak takes about 28-30 days to dry, so you’ll be able to do 12 loads in a year. Each load will need to be 42,000 board feet to give you the 500,000 board feet you need for the year. See similar questions...
