SIP exterior siding- Tips for installing cedar shiplap or TG
gpolkin
| Posted in General Discussion on
I am working with my son on siding his SIP tiny house and am in need of advice regarding siding. Neither of us are very handy so we are doing alot of head scratching.
The plan is to install cedar shiplap or TG siding. I have two pressing questions:
Our plan is to run vertical 1×3 “strapping” every 16 inches to allow for airflow. Plan is to use splitless ring shank siding nails for both strapping and siding. Does this approach seem solid?
The house is only about 14 feet long. Do you have any recommendations on the length of siding you would use for this length of run? Should I try to use single boards or are multiple better.
Thanks in advance for any help that you can offer.

Sounds like a good plan. Make sure you seal or paint all sides of the cedar first and use full length boards.
Yeah, prime the cut ends. Gap any joints sufficiently to caulk (about 3/16").
Assuming you mean horizontal siding, then yes, your plan sounds good. Make sure to provide a means for air to flow behind the siding at the top and water/air to flow out at the bottom, with both openings protected against critters using a screen or vent material.

i think it's great one of the editors is spending time here. Keep it up!
Your approach sounds good especially taking into account the suggestions of the other posters. I would also recommend screwing the strapping instead of nailing if you are only attaching it to the outer OSB skin of the SIP. Fourteen foot lengths of siding should be easy to come by.
From the standpoint of appearance, if you don't get 14 foot boards, and don't want so much waste, consider getting 16 or 18 footers and going something like
14
2 + 12
4 + 10
6 + 8
Etc
Only mix them up a little so that you don't get such an obvious a stairstep pattern. Eg: 14 then 6+8 then 2+12 then 8+6 then 4+10 then 10+4 then 6+8 then 12+2 then 8+6 then 14.
