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.
