1. GENERAL
Wedges / clips installed over masonry ties
can be used to attach ROXUL insulation
boards. Non-proprietary or proprietary
masonry ties can be used.
2. DESIGN
Spacing and design of the masonry tie
pattern should follow accepted practice and
be adequate to support wind and dead
loads.
Where permissible by codes and design, the
spacing of ties should be made to be 16” or
24” in at least one orientation (vertical or
horizontal) to allow easy installation of
ROXUL insulation boards with little or no
cutting of the insulation.
3. INSULATION ATTACHMENT
Wedges or clips over masonry ties can be
used to hold the insulation in place at board
edges. Additional fasteners can be used in
the middle of boards if needed.
The average number of masonry tie wedges
and / or fasteners holding a single piece of
insulation should be a minimum of 5.
Designers can increase the number of
fasteners or wedges to meet specific
conditions and design requirements.
4. FASTENERS
ROXUL recommends wedges or clips
designed for the particular type of masonry
tie being used.
If additional fasteners are required in the
middle of boards these can be:
 Plastic cap nails
 Screws & washers
 Insulation Fasteners
 Impaling Pins
5. STPE – ADHESIVE WRB
Some STPE based WRB (Weather
Resistive Barrier) compounds have
adhesive properties prior to curing and can
be used to attach ROXUL stone wool
insulation to the wall when used in
combination with brick ties and wedges
around board edges.
Follow manufacturers direction when using
an STPE based WRB as an adhesive for
ROXUL insulation.
