1 1/2 storey, upper level (sloped ceiling):

2x4 rims, 16in apart

I want to extend 2x4 rims by 2" with metal frame. What is my best option:

a) put frame vertically (along the existing rims); I thought of buying 2 5/8 or 3 inches wide, and screwing to the rims

b) put frame horizontally

I will be mounting standard 1/2" drywall sheets to the frame

Please note the rims are angled at 45 degrees! Note: additional frame is to add extra insulation (spraying 2 inches of foam)

Hi Cyril,

Have you thought about using 2x2's and nailing, gluing or screwing to existing 2x4's? If you are after extra cavity space for insulation this may be your best option.

Hi Scott,

I discarded the idea of using 2x2 for few reasons:

a) I need real 2 inches extra, 2x2 are about 1.5x1.5 really

b) I found it extremely difficult to find 2x2 that are straight, not twisted or curved

c) Thermal bridging

d) at some of the corners I can feet metal stud, but not 2x2
