Insulating brick home

Three years ago we moved into a 1960 brick ranch style home. We are ready to update our insulation. The insulation in the attic has settled to about 4 inches. How much should we add to that? We have no idea if the walls are insulated. Is it possible to blow insulation into the walls of a brick home? I apologize for being D-I-Y illiterate. Thanks for your time.

The R-value of attic insulation recommended for any locale is determined by temperature ranges. In general, recommendations are to increase attic insulation to R49 if retrofitting a dwelling.

This site will show you values for your locale.

This provides further information, based upon location.

Usually walls in house of the 1960's vintage are not insulated. There is a benefit to insulating walls as well as attics. Blowing insulation into the existing wall is an excellent technique of insulating the walls.

Hope this helps.

When you go for more insulation in the attic and you should dont forget about the rafter foam vents. They are so the air from the over hang vents can get up over the new insulation and into the attic.
Brick 1960 Are you sure did you check it out. Even before then they had started to build the brick homes as a veneer
brick on the outside of a full stud wall. They still do this to day.So Id check the outside walls inside and find out just what you have and does it have some insulation in it are need some.

Greetings to all..

I have a house in OKlahoma that has R-30 in attic, putting more in
next week to bring it to an R-49..

The house is a single story brick.. Code in OK doesn't require
a vapor barrier or a house wrap AFAIK...

I have contacted an insulation contractor that does a lot of "foam" insulation.
There is about a 1" -3" gap between the brick and exterior wall.
I have heard of people in this aree having that air gap filled with
foam to help insulate and also help reduce noise..

Has anybody had experience with injecting foam between the brick
and exterior walls..

any pointer appreciated..
