3 Reasons to Flash with Reinforced Scrim TPO

Most new single-ply thermoplastic polyolefin (TPO) roofs are installed using a standard .060-mil membrane with reinforced scrim. Also known as field membrane, the TPO is made up of several layers. The top layer – about 25 to 30 mils – is typically white and contains the polymers that provide the reflective properties, the color agents, and stabilizers. The middle layer is where the scrim is located. The scrim is a piece of fabric that reinforces the membrane for better performance. Lastly, the base layer is typically darker, often gray and can be made up of recycled materials.


What Are the Benefits of Flashing with Reinforced Scrim TPO?


Compared to detail membrane, reinforced scrim enhances the performance of TPO to produce a better product that lasts longer. Whether it’s being used for drain pipe or scupper, reinforced scrim TPO creates a superior product.


Using prefabricated reinforced scrim TPO flashings saves significant time in the field. Crews don’t have to customize flashing solutions on site and work more efficiently to get more work done in the same amount of time.


Detail membrane which is not reinforced is typically more expensive than field membrane because it is made up of more of the TPO polymers and costlier ingredients. It also has to be made in the field which adds expensive labor hours to the equation.

A Superior Product

Acme Cone’s prefabricated flashings are made from .060-mil reinforced TPO membrane – the same high-performance material that is being installed on the roof. With most roofing failures happening at a penetration point, flashing with the same material that is protecting the roof’s surface is the ideal solution.

In addition to superior performance over detail membrane, the time savings of not creating flashings in the field means that crews work more efficiently and can get more work done in the same amount of time.
