Installing Nu-Wood Products
Always use a combination of non-corrosive screws and Nu-Wood Adhesive when installing Nu-Wood items to the subsiding. When a foam board style subsiding is used, be sure the screws penetrate the foam and are secured to the wood framing behind. Always apply flashing above all windows, doors, and other openings before installing millwork. In many cases it is also recommended that flashing be used above the millwork itself. Once an item is installed, caulk the perimeter with a silicone base caulking to help prevent water penetration.
If there is vinyl siding, Nu-Wood pilasters, headers, sunbursts, and louvers can be routed at the factory to help conceal the J-Channel. If parts are routed, it is very important they are properly caulked. Follow proper finishing and patching instructions at this point.
OVER VINYL SIDING
It may be best to apply Nu-Wood directly over vinyl siding. Be careful not to restrict the expansion and contraction of the siding. This may be achieved by placing the millwork in position and pre-drilling pilot holes where all screws will be located. Remove the part and expand the mounting holes in the siding with a larger drill bit, allowing for proper movement. Then screw the item into place without over tightening. Using this application, an adhesive is not necessary. Be sure to follow patching and finishing instructions before completion.
In many new construction applications, the millwork items will be applied first and the mason will brick around the items. Be sure to properly flash and caulk all items during installation and after the brick is applied. When Nu-Wood is mounted over brick, be sure to use non-corrosive screws, anchors, and Nu-Wood Adhesive.
When installing Nu-Wood, always make certain proper flashing is installed where necessary. Special attention must always be given above windows and doors since these are points where moisture can get inside the home.
