Here are a few tips regarding the different choices
available:
Metal Box (Factory Built) Fireplaces:
There are many metal fireplaces to choose from made by
multiple manufacturers. While a metal fireplace can be a great option for many
cost conscious applications, there may be factors that exclude this choice for
outdoor use. Metal fireboxes are cost efficient and easy to install
however extreme temperature changes and weather conditions could dramatically
reduce the life of the product. Ensuring a metal fireplace is protected from
the elements would be important.
Traditional Masonry Fireplaces:
Not many will argue a masonry fireplace is beautiful. Again,
there are many factors that go into the decision for this type of unit.
Traditional masonry fireplaces can be customized and built to individual design
preferences however may take a long time to build, a factor which contributes
to the cost for installation. Though there is a basic design standard for
traditional fireplaces, each one is unique with no performance testing. A
skilled mason can do a beautiful job and produce a quality product; finding the
right mason with the experience and one who will work within your
budget is key.
If choosing a traditional masonry fireplace, a good
resource is www.stonefoundation.org
which lists stone masons and masonry contractors around the country. Be
sure that they are licensed, check references and visit the mason’s past jobs.
Modular Masonry Fireplaces:
Also known as Prefab Masonry Fireplaces, Modular Masonry
Fireplaces were first introduced to the US market by Earthcore Industries in
1989. These fireplaces, made from pumice stone are molded components which
stack together with mortar to create a traditional or contemporary fireplace
look. Modular masonry fireplaces are tested for performance and draft
prior to being put on the market. This testing can therefore provide more
assurance of a well performing fireplace. There are many benefits of a modular
fireplace, the first being the cost savings on installation; the material is
lighter weight than concrete, provides a free standing system, each piece is
made to be installed in only one simple configuration and the fireplaces can be
installed in less than a day. Able to withstand intense heat, the pumice stone
does not absorb heat like traditional masonry brick, therefore has lower
clearances to combustible framing and puts more heat into your area.
When choosing your modular masonry fireplace the most
important thing to look for is if that product has been tested and listed
UL 127 (safety & performance testing). Another thing to pay attention
to is the material used to make the fireplace. Many companies boast that
their fireplaces are “the strongest on the market” or list a PSI compressive
strength – This means that their fireplaces are made primarily of concrete.
Concrete does not handle extreme heat changes and is subject to a material
breakdown. (Remember that cracked sidewalk outside your house growing up? The
one that you always tripped over?).
No matter which fireplace type or manufacturer you choose,
be sure to check with your local building inspectors for compliance to codes
before you build, Be smart, safe and informed.
