If you have always been fascinated by tile backers, you will be glad to know that DensShield is the first backer board to feature an in-built moisture barrier.

Compared to fiber cement, DensShield absorbs less moisture. This feature makes it perfect for tile installation in highly humid areas like the pool or bathroom.

DensShield can be used in home remodeling or new construction projects. For the average DIYourselfer, DensShield is very easy to use. It cuts like drywall.

Therefore, the installation process will be incredibly effortless. You don’t need special equipment for installation. This board can also be used in areas that aren’t exposed to a lot of moisture.

What is DensGlass?

Even if you have never worked in a construction building, you have probably seen sheathing used in most projects. Sheathing is the outer layer or casing used on a construction building.

When constructing a house, sheathing protects your property from weather elements, and it can also be used to provide insulation. Similar to tile backers, many brands make sheathing for construction projects. One of them is GP’s DensGlass.

Out of the many sheathing brands in the market, very few come close to DensGlass. Due to its advanced properties, this sheathing is often used to offer protection in areas that experience extreme weather conditions.

It is water-resistant. Therefore if you are building a home or commercial property in an area, that experiences a lot of rainfall and snow.

Despite its ability to offer protection to construction buildings located in areas that experience adverse weather, people also use it in locations that experience typical weather.

That is because, with DensGlass, you are assured of maximum protection. Similar to nearly all products made by GP, DensGlass is mold resistant. That’s another benefit you get from using DensGlass.

Protection from the elements aside, the use of DensGlass as sheathing adds stability to the structure of your property. With DensGlass installed, the surface becomes smoother and flatter, creating a stable structure that isn’t vulnerable to sagging or buckling.

There is also another advantage of using DensGlass. It adds insulation to the structure. With DensGlass, your home or commercial building will benefit from additional insulation. That will ensure your energy bills are regulated and remain low.

As great as DensGlass is, there is one drawback you have to familiarize yourself with, and that’s the fact that it’s incompatible with forced air heaters.

Property owners interested in adding these to their homes should be aware of that issue. When you use DensGlass sheathing alongside forced air heaters, the latter will form water vapor, which will lead to condensation.

Besides this, the DensGlass fiberglass mat gypsum sheathing does an excellent job protecting your structure from the elements and offering more benefits such as stability and insulation.

You should also know that it can be used as a substrate under siding, stucco, stone, and brick.
