CertainTeed Vinyl Siding Installation Guide

Continuous foam insulation systems (SIPs)

Continuous foam insulation systems (e.g. rigid insulation, structural insulation products) thicker than 1" create a condition where CertainTeed vinyl siding and polymer shakes cannot be properly attached to the existing framing members, steel studs, or structural sheathing.

The easiest way to meet the fastening requirements for CertainTeed siding is to install 3/4" structural sheathing (such as OSB or plywood) over the continuous foam insulation. However, the wall assembly must be designed in such a way that the structural fastening surface that is re-established on the exterior of the insulating products is sufficient to meet the requirements of ICC-ES Evaluation Report ESR-1066 for vinyl siding or ICC-ES Evaluation Report ESR-3085 for polymer shakes.

CertainTeed does not provide instructions for wall design or assembly that specifically relates to the fastening requirements for re-establishing a structural fastening surface for CertainTeed vinyl and polymer siding. However, FastenMaster® provides two documents to assist in successfully re-establishing a structural fastening system on the exterior of a continuous foam insulation system:

•Technical Evaluation Report (TER No. 1009-01): Use of FastenMaster HeadLok™ Fasteners to Attach Cladding and/or Furring to Wood Framing through Foam Sheathing

•Technical Bulletin: Attaching Exterior Wall Covering Assemblies with Foam Sheathing to Steel Wall Framing

The Fasten Master reports must be used in combination with ICC-ES Evaluation Report ESR-1066 for vinyl siding or ICC-ES Evaluation Report ESR-3085 for polymer shakes to determine attachment requirements. In addition, all the installation methods included in this manual must be met.

Fastening CertaWrap™ Weather

Resistant Barrier

To secure the Weather-Resistant Barrier, use the appropriate recommended fasteners and fastening schedule for your application.

Wood-based sheathing

When attaching CertaWrap Weather-Resistant Barrier on wood- base sheathing, such as 7/16" OSB or 15/32" plywood, apply plastic-capped staples or plastic-capped nails every 32" vertically and horizontally.

Open-stud construction or non-structural sheathing

When attaching CertaWrap Weather-Resistant Barrier on open studs or non-structural sheathing, apply plastic-capped staples or plastic-capped nails long enough to penetrate the stud a minimum of 5/8" every 32" vertically and horizontally.
