Installing a pet door
into a porch is very common for many pet owners. There are a wide variety of porches from
4-seasons rooms, screened enclosures, lanais, etc. In order to make
things easier we break porches down into two distinct groups,
Framed in Porches (screened porches, and aluminum lanais, things of that nature)
Solid Wall Porches like you would find in a 4-season.
Framed in Porches
Framed in Porches usually have wooden supports or an aluminum structure
that has screen or glass. Pet doors are typically installed into an
opening that is framed out for the pet door. This is most often done
beside a support beam or post to provide stability to the pet door.
This can be a very easy application if the pet door you have selected
is rated to fit that support beams thickness as your framing, for
example if you use 2x4 construction make sure you have a pet door that
fits a 2 thickness.
Solid Wall Porches
Solid Wall Porches tend have thinner than normal walls. It will be
a good idea to know how thick your wall or knee wall is. Sometimes a
door mount can fit up to a 2 inch wall but in most cases the porch walls
are too thick and a conventional wall mount would be needed as it would
provide a better fit. Please pay very close attention to the wall
thickness range of the pet door you select, as sometimes these wall
mount kits will fit a minimum thickness as well as a maximum.
