Building a porch / mud room
Posted: Fri Feb 22, 2013 4:02 pm
We're considering adding a porch / mud room to the front entry of our MH, probably 8' x 10'. This would be on deck blocks or similar, set up on posts, very simple, but insulated. Going to use standard 2" x 6" construction, fibreglass insulation, exterior sheathed in OSB, then tar paper and cedar shingles. Roof would be shed style with no peak following the roof line of the MH, shingled. I'll wire it for a heater and lights, inside will be vapour barrier & drywall, nothing fancy here. I think these are pretty common. Any idea of cost to build something like this?
The other question is attaching it to the MH. Our MH is up on blocks, as would this porch, so I understand attaching them solidly together could lead to problems because of frost heaves. One idea I had was to attach some kind of rubber "gasket" between them, but actually not connect the porch to the MH other than the rubber. This would keep drafts and stuff out but allow a little movement. The roof of the porch would tuck under the MH roof and continue the same roof line (it's a pitched, shingled roof).The MH movers showed me some rubber they use for the bottom of skirting that is about 3" to 4" wide, fairly thick like maybe 1/4" or better. I was thinking something like this although I have no idea what to buy for that. Other idea was to simply build it with a small gap between the MH and porch frame, and fill the gap with expanding foam - but that might grab too much I thought. Any other ideas on what to use to connect a porch to a MH?
