Replacing Insulation on a Feralvilla Shelter
Posted by on 9/19/2017
We occasionally receive questions about repairing/replacing damaged
insulation on our shelters. The insulation we use is designed for
insulating, but doesn't necessarily hold up well against the assault of
critters. Raccoons are especially notorious for wrecking insulation, but
there are a few cats that are also culprits.
We install the
insulation with a combination of adhesives to give quick adhesive and
long term durability. Some older shelters used a single heat-applied
adhesive. The insulation we use in the original construction only works
well when applied to clean, flat, dry surfaces. The two scenarios for
insulation repair/replacement are described below:
1. Repair of insulation that has come loose (but isn't damaged)This
happens on older shelters that used only a single, heat-applied
adhesive. For both repair methods, you will need to start by making
sure both surfaces of the repair are clean and dry and free of loose
materials. The most durable repair requires a caulking gun and the use
of a professional-grade polyurethane sealant called OSI Quad. OSI Quad
is only available for use with caulking guns, so if you don't know how
to use a caulking gun, or would rather not try, skip to section B.
A. OSI Quad (permanent, but slower and more involved)Perform
this procedure with the shelter at room temperature. Apply a generous
1/4" to 3/8" bead of OSI Quad in patterns on the back to make sure you
have lines of adhesive every 1-2" across the surface of the insulation.
Press the insulation in place firmly. You can adjust the position until
it's where you want it. The piece will need to be held with pressure for
24 hours. Placing books on top of the insulation piece is a good way to
do this without pressing so hard as to damage the insulation. Note that
OSI Quad has a moderate odor, so it is advisable to do this outdoors,
or in a garage, if you're sensitive to odors. Keep the shelter open
during this time to allow odors to dissipate. After 24 hours the
adhesive is cured sufficiently for the shelter to be returned to
service.
B. Scotch Double Sided Permanent Outdoor Mounting TapeThis
will work best if the shelter is at room temperature and dry. Using
scissors, cut pieces of the tape 2-3" long and apply them at the
corners, sides and across the middle. Be generous with the tape.
Position the insulation piece as closely as possible and when ready,
press firmly in place. Once pressed in place, the piece cannot be moved.
Firmly, but without crushing the insulation (using the palms is a
fairly safe way to do this) move your hands back and forth several times
pressing the insulation in place. The shelter may now be returned to
surface.
2. Replacement of damaged insulationRequired materials: Reflectix and Scotch Double Sided Permanent Outdoor Mounting Tape
This
happens when the insulation has been clawed, chewed, etc. by an animal.
Using a plastic putty knife (or your hands, if you have nothing better)
remove as much of the damaged insulation as possible while trying not
to damage any intact insulation. You will likely not get the surface(s)
completely clean of old adhesive and insulation. You will need a product
called Reflectix (or similar). This is similar to double-sided bubble
wrap but with an aluminized foil film on both sides. Cut a piece of
Reflectix to the proper size using scissors. Cut and apply pieces of
tape 2-3" long at the corners, along the sides and across the middle of
the Reflectix piece. Position the Reflectix piece to the correct
position as closely as possible then press it firmly into position.
Using your palms, press firmly back and forth across the surface to
engage as much of the tape as possible. Once this has been completed,
the shelter may be returned to service.
