Kathy Cabana, "Good afternoon to you".
I my self would go and look in the yellow pages for a
company that make air vent pipe/ducting systems.
I would the ask them from where do they buy their
insulation material from, get a guy to come down
and take mesurements of the size of the ducting, and get
them to fit it, the cost will be less than what you will
pay for new A/c units etc.
BUT' you can become a "Thermal Engineer" for a day, and
it could save you some money.
You can insolate the ducting/pipeing your self, if its easy
to get to, if not get the company to do it.
Go to you local hardwere store/builder supplyer, they
will have in stock some 2" polystrine, some glue ( for polystrine)
not just any old glue will do) it has to be glue for polystrine.
"Thats important" some glues can melt polystrine...
Not knowing the size of your ducting. let us just say
top,bottom,sides, now the top and bottom are one size, the sides will
be another.
Cut the polystrine the same size as the top/bottom, glue the top first
now when all the tops are done cut the poly for the bottom (should be the
same as the top) but dont glue it yet.
now to make the sides, cut the poly 4" wider than the ducting
" 2"top-side-2"bottom" you will have also bought from the shop some
4"nails ( I can read your mind, no, you are not going to nail the poly)
Put some glue onto the side of the ducting, placing the side panel that you
made push a nail into the side panel into the top poly ( that was glued earler)
do this both sides, now this is the part where you will need three hands,
remember you have already cut the bottom panels, again, glue ( not too much) the
ducting and place the bottom panel into place, your two hands are now holding the
panel your other hand will push in the nails through the side panels into the bottom
panel. then you have done all that you can now tape it... using 2"ducting tape that
will hold anything in place.
So now you know how to be a Thermal Engineer.
Items you will need from the shop:
4" nails.
Glue ( for ploystrine nothing else will do)
2" Ducting tape. buy one roll first and see how
much you use.
PS: Because its out of sight, does not mean you have to
do a sloppy job. the better you make it the better it
will work..................
