Horizontal Strapping For Siding

To provide a capillary break and to vent the cavity to facilitate drying.

Horizontal strapping for siding.

Ensure a maximum spacing of 16 center to center c c between furring strips figure 3. We did this mostly to protect the house from the elements during the ridgid foam. Corners are often needlessly fortified with furring strips or strapping where they should ideally be left open and able to dry. Use j channel to receive vertical siding.

There are two main functions to rain screens. Attaching the vertical barn wood siding. The crews usually install the strapping vertically for horizontal siding applications letting the wood strips align with the wood stud framing on the other side of the sheathing for a strong long lasting installation. We have done several vinyl siding jobs over foam with strapping with no problems none yet anyway.

The bumped out rain screen design added to the energy efficiency and durability to the natural wood siding. Horizontal furring strips for installing siding vertically use 1 x 4 kiln dried furring strips with a moisture level less than 19. If needed install horizontal furring strips every 12 or a solid nail able sheathing prior to the siding. One solution is horizontal strapping on top of the vertical strapping but most of the proprietary rainscreen products will also provide a suitable drainage cavity as well as support for the cladding materials in a way that is easier to build.

While sloping the horizontal strapping or cutting drainage notches might deal with any intrusion of bulk water that gets past the siding it doesn t allow any ventilation of the space. Establish your base line. If horizontal siding is used a j channel or starter strip must be used. Double furring at the corners.

This action will help to level the surface and provide sufficient material for 3 4 fastener penetration. After stripping the original wood siding we wrapped the house with tyvek taping all seams. If starter strip is used it is necessary to provide at least 3 8 9 5mm clearance for proper engagement of the siding. A cladding material that provided its own code conforming capillary break would also be acceptable.

Diagonally installed furring is an option that can also work without needing a second layer. Use enough fasteners to properly secure the siding material to the wall. The most recent was 2 of thermax over pine board sheathing.
