Insulating Floor Of 3 Season Porch

In terms of energy savings there isn t much benefit to insulating an unheated porch.

Insulating floor of 3 season porch.

This can be stapled up between the floor joists. That would include the ceiling walls and underneath the porch floor. Use a vapor barrier to keep your floor above free from condensation caused by the new insulated area. Also imo the radiant barrier is a waste of time and just reduces your insulation.

However doing so will prevent cold air from seeping into the porch and may allow you to use the porch for a few weeks longer before winter arrives. A contractor i hired to insulate under my 3 season porch floor has used regular pink insulation r 27 but it has fallen out four times so far now half of it is on the ground. Enclosed but uninsulated sitting areas are known as three season porches but if you live in a northern state cold weather can reduce that to two or even one and a half seasons. I was really surprised to see all the brand new insulation completely.

We just had a 3 season room built in place of our deck. I looked under there today to see if i could come up with an idea for closing the gap to animals and debris. If you re looking to extend the use of your three season porch or even turn it into an all season porch you ll need to look at adding insulation. Insulating the floor is an important step in porch conversion.

Our contractor originally said he d add some lattice work between the bottom of the house and the ground but later said there was not enough space to work it in. If it is above grade winter drafts will make the room too cold to use no matter how well the walls and ceiling are insulated. Roll out the fiberglass insulation sheets between the joists facing side up making sure it is snugly in place. Make sure that you wear gloves.

Basically you should be thinking about insulating the roof floor and walls to ensure the maximum benefit. After insulation is installed no poly vapor barrier only kraft faced so that it is semi permeable go back with 3 4 t g advantec then your floor then baseshoe.
