HOUSE INSULATION AND HOUSEWRAP

For the typical siding application, housewrap or sheet insulation can be

placed on the exterior of the wall. Housewrap will prevent drafts from

occurring and will also shed moisture that gets behind the siding. Install

insulation under the housewrap if needed (FIG 6.1).

SURFACE PREPARATION

Remove and replace any rotted or damaged boards. Check for waves in

the wall and shim out if necessary. Nail or screw down any loose boards

or trim. Scrape away any old caulking. Pay extra attention to areas that

may interfere with the new trim pieces. Apply new caulking where old

caulking was removed and ensure all air leaks are sealed. Remove or

loosen objects such as downspouts, cables, planters, shutters, and other

items that may be in the way of new siding. Always contact a profes-

sional to remove meter boxes or power lines.

NOTE: Best practice is to remove the old siding before installing

Ply Gem Steel Siding.
