Ask John #14: Strapping Vertical Siding

Post Topics: Ask John

Question:

I have a house with plywood and house wrap. Do I need to strap the house or install insulation before I put on board and batten vertical siding. If I am not worried about the R-value, is it O.K. to go right on top of the house wrap with the vinyl siding? My biggest concern is that there won't enough ventilation behind the siding.

Thanks,

Wayne
 

Answer:

Strapping is recommended for board and batten but it isn't necessary. It can be installed over the plywood and house wrap. The most important thing to keep in mind while installing is to leave room with the screws for the siding to expand and to follow the manufacturer's guidelines.
