5/4x Rainscreen Installation

Step-by-Step Installation Guide

Install house wrap to prevent moisture intrusion. (Always follow the vapor barrier manufacturer’s instructions)
Install the baseboard (horizontal furring strip) with stainless screws. Ensure the baseboard is level.
Align furring strips vertically on top of baseboard 16" on center. Attach furring strips.
Install starter clips (included with the hidden siding fastener kit) on your baseboard. Align each starter clip with the furring strips installed in step 3.
TIP: use a chalk line reel or laser to create a level line
Install the first Rainscreen Siding board on top of the starter clips.
TIP: Use a level to ensure this first board is aligned properly
Place 5/4x siding fasteners into the pre-molded groove.
Drive a stainless steel screw through the siding fastener into the furring strip at a 45 degree angle.
Repeat the process by setting the proceeding siding boards on top of the installed siding fasteners until the top board is installed.
You may need to rip the top of the hardwood siding to the appropriate width to fit. In this case, use blocking behind the siding secured with facescrews and hardwood plugs for a smooth fastenerless finish.
Cap off the top board with blocking or flashing to prevent water and insects. For soffits and overhangs, trim the board 1/4" short to allow for better ventilation behind the rainscreen and the wall cavity.
