Fire blocking when finishing a basement.

24 Mar

Fire blocking isn’t hard to do, and doesn’t add that much more to the budget.  Codes vary depending on where you live and in Warren County, Ohio where I live code requires you to use either 1 1/2 treated lumber or 1/2 drywall every 10 feet vertically from floor to ceiling, and above all outside walls horizontally, ceiling coves, soffits, fireplaces, HVAC chases, etc.. 

If you have never done this before, you probably think what a headache, but it isn’t that bad, and whether you are a contractor or homeowner, it is a neccessary step for safety.

To save time I use treated 2×6’s as my top plate on all my outside walls and butt them right up against the concrete or insulation.  You could save money and throw up a strip of drywall before you install your wall, and install a strip vertically (which I do) every 10 foot.  I use drywall in all my ceiling coves, soffits, fireplaces, HVAC chases, etc.,  it doesn’t have to be pretty, cause a lot of time you are installing pieces around plumbing, electric, and HVAC.

I take it a step further than code requires, and spray fire blocking foam in all my cracks.  This should cause a fire to go out soon after it starts due to lack of oxygen inside the wall.  I perform the same work for my customers that I would do on my own home.

I hope this helps you out:)
