How is paperless drywall different from traditional drywall?
Paperless drywall was
developed recently in order to combat problems with mold. As stories of mold-related health concerns have proliferated
in the news during recent years, all of the major drywall manufacturers have rolled out new products designed to resist the
growth of mold.

Traditional drywall is made up of gypsum
and paper. To create a sheet of drywall, the gypsum is pressed between two thick pieces of paper and then kiln-dried.
Since the paper covering on traditional drywall can allow for the growth of mold if it becomes damp or wet, paperless drywall
was developed in an attempt to combat this problem.
Paperless drywall is similar to traditional drywall in that it also contains a gypsum
core. The difference is that instead of using paper as an outer wrapping, fiberglass is used instead. The gypsum
core in paperless drywall is also water-resistant, unlike the core of traditional drywall. These changes in the makeup
of the drywall are intended to reduce the risk of mold growth by making the drywall as resistant as possible to moisture and
water. While the new paperless drywall products are not mold-proof, they offer more protection from the threat of mold
than traditional drywall.
Applications
Paperless drywall can
be used in any area where standard drywall can be used, and it is recommended by manufacturers for use especially in areas
where higher moisture levels could raise concerns about mold. Bathrooms, kitchens, basements and garages are all areas
that could possibly benefit from the installation of paperless drywall. While paperless drywall is more water-resistant
than traditional drywall, it is not intended for use in conditions where it will be exposed regularly to water, such as inside
a shower stall.
Pros and Cons of Paperless Drywall
There are benefits and
concerns to consider with paperless drywall, a relatively new product. Some advantages to consider when choosing it
over traditional drywall include the following.
- It is designed to offer an improved level of protection from the growth of mold.
- The surface
strength of paperless drywall is greater than that of standard drywall due to the added rigidity of the fiberglass covering.
It is less likely to become damaged because of this attribute.
- Paperless drywall offers
special advantages in high-moisture areas, such as basements and bathrooms, where mold growth is a big concern.
While
there are some great features offered that will be helpful in certain applications, there have been some complaints and concerns
raised, as well.
- Paperless
drywall is more expensive per square foot, compared to traditional drywall.
- In some areas of the
U.S., availability
is also a concern. Paperless drywall is a fairly new product and may not be available in some areas.
- A major concern that has been the topic of some debate is that paperless drywall is more difficult to install and finish
than standard drywall.
Installation and Finishing
There has been some discussion, especially among professional
drywall installers, about issues related to finishing and installation of paperless drywall. The fiberglass covering
is far more rigid than the traditional paper covering. While this can be beneficial because it adds to the surface strength
of the drywall, it has also proven to be problematic in some instances where installers have run into trouble mounting the
drywall with screws. Traditional drywall is soft enough to “dimple” when the head of the screw comes down
on the surface, providing a countersink that will finish over smoothly later on. Some installers have had problems with
screw heads not sinking well into the fiberglass, as well as trouble getting screws in straight, causing extra work and frustration.
The fiberglass covering has also been reported to cause skin irritation on par with that caused by the installation of fiberglass
insulation.
The surface of the fiberglass on the paperless drywall is not as smooth as the paper
covering on traditional drywall. A mirror-smooth drywall finish is very popular in some areas, such as California. In these cases, extra finishing is often required in order to bring the paperless drywall to the
desired final smoothness. Some manufacturers have taken steps to avoid this issue by producing a smoother-textured fiberglass
covering, but it has been a concern with some brands in the past.
Paperless drywall is a
recent innovation. It will be interesting over the next few years to see how new installations of it are holding
up, and if it is living up to the claims that manufacturers have made. Inspectors are likely to see more
frequent instances of paperless drywall use, and time will tell if this product is destined for more widespread popularity
in the future.
A Few Notes on Energy Savings
- Many people believe that furnaces work harder than normal to warm an area back
up to a comfortable temperature, which will counteract energy savings gained from turning the thermostat down. This belief
is a misconception that has been disproved by years of studies and research. Fuel is saved between the time the temperature
is stabilized at the lower level and the next time heat is needed, while the fuel required to re-heat the space is roughly
equal to the fuel saved while the building drops to a lower temperature.
- According to the U.S.
Department of Energy, consumers can save 10% on their utility bills by setting their thermostat back 10° to 15° for
eight hours. This can be accomplished easily with a programmable thermostat.
- Be careful not to set
the thermostat so low in the winter that pipes freeze, or so low during the summer which may allow humidity-spawned mold
to grow.
In summary, thermostats are used to ensure the comfort of building occupants through the
proper control of the heating and cooling cycles.
