| Interior wall materials need to be fire-resistant in order to prevent structural damage within the walls, and ceiling for that matter, if ever there is a fire. The more fire-resistant your home the more insurance companies like it. |
Often insurance companies give discounts on home insurance rates for using materials that are impervious to fire. Check with your agent as to what types of materials will qualify for discounts.
Following are a couple of the most popular substrate materials that you can add to the interior of your wall structure:
Cement Board—is created for use in extreme conditions.
It's perfect for tiled areas—especially in the shower. It can also be used wherever a fire-wall is needed, such as in a chimney, fireplace, or on walls located between the home and garage.
Cementious board is tough and resists against scraps and bangs. Therefore it is great for walls that are susceptible to abuse.
If you are concerned about cost, it is more expensive than drywall, but you won't be making repairs as often an that could save money in the long run.
Gypsum Board—(aka: "Drywall", "Sheetrock", etc...) is a plaster type material sandwiched between a thick paper product.
There are several different thickness used for different applications. For damp rooms such as kitchens and baths, a there is a waterproof drywall designed to prevent moisture damage to the walls.
Installing gypsum board is hard work, but for those "do-it-yourselfer's"; you can do it as long as you have the right equipment, can lift some weight, and most importantly—learn the proper techniques. http://www.findarticles.com/cf_fmhymn/m1080/n10_v48/21281397/p1/article.jhtml
A Personal Story:
When building our home, our contractor had just one person install the gypsum board. I was so amazed because some of the sheets he was putting up on the ceiling were 16 feet long!
How could one person do it?
He told me, "The key to doing any job efficiently...
... is having the proper tools and knowledge."
If you are planning the exterior walls of your home to be made of either concrete or masonry products, your walls will already be fire resistant. Therefore, the interior side of the walls should not need an additional fire-stop added. However...
...unless an industrial look is what you're after, poured concrete and block walls will require some additional work.
There are a number of different materials that can be added to "finish off" the wall, such as: smooth or textured plaster, gypsum board, paneling, brick or stone, and tile to name a few.
