​How does it work?

The CondenStop fleece absorbs, stores and releases significant quantities of moisture where condensation would normally occur. When the temperature of a metal roof drops below the dew point, the CondenStop fleece will absorb and store the condensing water vapor. The absorbed water will evaporate again into the ambient air under appropriate temperature and ventilation conditions.

Why is condensation an issue?

When there is a temperature difference between inside and outside a building, condensation can form on the interior of cold metal panels – it is a natural effect.

What is the life expectancy once applied?

CondenStop is made from durable polyester materials designed to last the life of the metal panels; a wide variety of testing and in-place projects confirms the product’s durability.

Is CondenStop factory applied to metal panels? And is it secure once in application?

Yes, it is factory applied making it faster, safer, and easier to install as compared to conventional material. The adhesion is quite strong.

What colors are available?

Light gray is standard.

What is the R Value?

The R-value is minimal, only 0.3691. However, the product’s value comes from its ability to store and release moisture where other materials cannot.

Does the moisture affect the metal?

No, it does not.

If CondenStop is used, does the building have to be ventilated?

Yes, a properly ventilated building is still important. CondenStop helps smooth out drying cycles but buildings should still utilize good ventilation practices.

What are the flame retardency properties?

Class I flame retardant per ASTM E84-04.

What are the absorption and drying properties?

CondenStop holds 21 lbs of moisture per 100 square feet. This equates to over 10 quarts of water per 100 square feet.

Will mold grow?

No, the microfibers of CondenStop do not support mold growth.

Does CondenStop limit sound?

Yes, it reduces noise from outside such as rain as well as absorbing sound from inside the building. ​

A-Frame Horizontal Roof

A-Frame Horizontal roofs give your structure a residential look. The sheet panels run from side to side and does not have purlins or ridge cap. The increase in price to upgrade to A-Frame Horizontal is the additional welding needed on your trusses (bows). An excellent option to keep your residential look for residential areas for a minimum upgrade costs.


A-Frame Vertical Roof

Known as the best choice for areas that experience extreme weather conditions, the vertical roof style is hands down the best choice for Michigan weather. The roof panels run from the pitch to the eaves causing heavy snows, rain, and natural elements to slide off the roof easily. In order to tie down the panels to the structure, we must add purlins or hat channels lengthwise making the structure more rigid. The finished look with special trim all around the roof and ridge cap makes this roof style the best option.
