A homemakers guide to Install Vinyl Windows in Engineered Rainscreen
A rainscreen siding installation includes formation of an air gap between the siding and the housewrap or the asphalt. The average, well-designed rainscreen wall will need the following:
• a water-resistive barrier (abbreviated as WRB);
• an air gap between this barrier and the back of the siding;
• flashings at all points of penetration and all vulnerable areas;
• Weep holes (made at the bottom of the window)
Need for a Rainscreen: This will help your walls in managing moisture and additionally in drying up the sheathing. This will further save your siding from moisture accumulation and keep it dry during the rain.
Further, the gap creates a capillary break which provides resistance to any form of wicking. Moisture held will be eliminated via evaporation or diffusion, stopping damage to your walls and windows. The water accumulated will drain via the gap to the weep holes.
Size of the Gap: Even a 1/16 inch gap provides an adequately sized capillary break which will facilitate drainage of liquid water and allow diffusion. However, variations in thicknesses of the material usually call for the creation of a rainscreen gap at least 1/4 inch deep.
How to create the gap?
There are primarily three ways to create a rainscreen gap:
• Furring strips. These are installed vertically, directly over the studs (16 inches on centre or 24 inches on centre).
• By using a three-dimensional plastic mesh product.
• Using a bumpy or wrinkled housewrap.

1. Make sure that the building paper and peel and stick are installed properly.
2. Place the window in the opening and centre it as accurately as you can.
3. Place ¼ inches shims under your window and adjust the same until they are level.
4. Use 1 ½ inches roofing nails, preferably nails that are galvanized, nailing every second hole on both sides.
5. Add a 1/8 inch shim at every second hole on bottom flange. Nail it properly.
6. Galvanized Window clips and 1 ½ inch treated screws must be used to secure the top flange.
7. Apply the next layer of rainscreen properly.
How much do rainscreen details cost?
Every project is different, but usually they add up to about 30% to the cost of a siding project.
