The first picture below illustrates a portion of a townhome unit s firewall in an attic that is totally sealed off to provide 1 hour of fire protection on both sides.

A firewall is a simple structure to implement consisting of a layer of drywall.
Owner is very interested in having the work done but.
Looked at a job air sealing and adding some insulation in a condo.
The preferred standard for firewalls involves using a type x drywall.
While different building code requirements allow for sheetrock in the building of a firewall.
For example if there is a middle located townhome with adjacent units on either side you will have 1 hour of fire separation at each side.
Designed as an extra layer of protection between the house and the garage an intact firewall resists the intrusion of fire into the home.
Material needed to fix a firewall at home.
The area separation component is added after the framing has been completed in one of the townhouse units and before the adjacent unit is framed.
Apparently when the condo s where originally built the common wall was not extended to the roof sheathing.
This allows space for fire blocking product to be installed between the floor levels.
Each upper level condo should be separated from the others in the attic space with some type of fire blocking fire impeding drywall.
Normally a 2 inch thick firewall is assembled at least 3 4 of an inch away from the wood stud or steel stud framing.
Because of this the condominium association wants a fire barrier put in if any work is done in the attic.
