Summary of the article:
1. Furring or strapping must be applied to create an even base for siding. Apply 1” x 3” (minimum size) wood furring, not more than 16” on centers. Shim low spots to create an even surface. For horizontal siding, install furring vertically.
2. Most panel siding requires a solid surface or backing for a secure and stable attachment. Furring strips provide reliable backing. The second — and most important — purpose of furring strips for siding is that they create a crucial gap between the siding and the weather-resistant barrier of the home’s exterior.
3. The furring strips, also referred to as battens or strapping, prevent direct contact of the wood siding with the weathertight vapor barrier, allowing it to ‘breathe’, preventing rot and product failure.
4. Underlayment or weather resistive barrier (WRB) is installed between the siding and the sheathing. This can be tar paper or a house wrap such as HardieWrap® or Tyvek HomeWrap®. HardieWrap® is great for keeping water out and at the same time letting water vapor escape from the house.
5. Nailing Siding Too Tightly: Vinyl siding will expand and contract with temperature changes. If the contractor nails the siding too tightly, it will restrict the movement and the siding is likely to crack. As a general rule, contractors should use a clearance of 1/32 inch between the siding and nail head.
6. NOTE: Vinyl siding must be applied over a rigid sheathing that provides a smooth, flat surface or an underlayment (such as wood, wood composition, rigid foam or fiber sheathing) that is no more than 1″ thick. Vinyl siding cannot be applied directly to studs.
7. While not entirely necessary, it’s quite important to have a house wrap underneath your siding on your home, especially if your siding is made of vinyl or something like it. While vinyl siding can protect your home from air and moisture, it does not create a vacuum seal on your home.
