DESIGN BASIS
1.
MECHANICAL ATTACHMENT
For permanent attachment, ROXUL stone
wool (mineral wool) insulation should be
mechanically attached or pressure held by
supporting members.
2.
ADHESIVES
Adhesives and adhesive applied stick-pins
should NOT be used for permanent
attachment of ROXUL stone wool insulation.
Adhesives, and adhesive based systems
can used for temporary attachment, but
mechanical attachment (or supporting
members) must be used for permanent
attachment.
3.
EXPOSED INSULATION
ROXUL stone wool insulation is not
intended to be left exposed to the elements.
Cladding should be installed after insulation
attachment. If the insulation is to be left
exposed, or installation takes place in bad
weather, the insulation should be
permanently mechanically attached and
covered with a breathable protective layer
(such as tarp). Designers can increase
number of fasteners to meet specific
conditions and design requirements
(including wind-driven rain-loads).
4.
DESIGN LOADS
Fastening connections should be designed
to withstand all the combined applied loads,
including (but not limited to) Dead-Load and
Wind-Loads. Where applicable,
consideration should also be given to
Seismic- Load, Live-Load and Wind-Driven
Rain-Load (Not covered in this guide).
5.
DEAD LOAD
Fastening connections should be designed
to withstand all the combined applied dead
loads, including (but not limited to) the
insulation, fasteners and any other
supported members or cladding.
6.
WIND LOAD (LIVE LOAD)
Fastening connections should be designed
to withstand horizontal loads imposed by
wind pressures. Wind loads often govern
lateral load scenarios
7.
FASTENER SELECTION
Fasteners should be: a) appropriate type for
the substrate; b) capable of withstanding
applied pull-out and shear-loads ; c)
numerous enough and of large enough
cross-section to prevent tear-through of the
insulation under expected conditions; d)
suitable for use outside if being used in
exterior applications.
8.
ENGINEERED DESIGN
The design of fastened connections is a task
normally completed, or reviewed, by a
structural engineer. The primary purpose of
this fastener guide is to provide suggestions
for attachment design of ROXUL stone wool
insulation attachment to various structures
and buildings.
9.
LIMITATION
ROXUL stone wool insulation boards are
suitable for mechanical attachment using a
number of fasteners and fastening systems.
Mechanically attached fastening systems
are subject to various loads including dead
load, wind load and seismic load; all of
which vary with location and over time.
WARNING: Failure to include safety factors
or adequately design for applied loads can
result in failure of mechanical attachment.
The determination of the specific design
requirements and safety factors regarding a
fastener system is the sole responsibility of
the installer and/or end user. ROXUL Inc
assumes no responsibility whatsoever for
any failure of insulation attachment or
related fastening systems.
