What thickness is TPO membrane?

What thickness is TPO membrane?

Review of TPO membrane manufactur- ers’ product literature reveals for 45-mil- thick membranes, manufacturers’ thick- nesses over scrim range from 15 to 19 mils. For 60-mil-thick TPO membranes, thicknesses over scrim range from 21 to 27 mils.

What spec section is TPO roofing?

SECTION 07 54 23 ADHERED THERMOSPLASTIC POLYOLEFIN (TPO) ROOFING PART 1 – GENERAL 1.01 SECTION INCLUDES: A. The Work specified in this Technical Specifications Section consists of providing Adhered TPO roofing as required to complete work.

Does TPO need underlayment?

Thermoplastic Polyolefin (TPO) TPO roofs can resist UV rays by reflecting the light off its surface. This makes TPO ideal for buildings that need an effective insulation system. TPO underlayment is relatively easier to install. A hot-air gun is used to melt the rubber down to fuse each sheet together.

How thick should a TPO roof be?

TPO is typically sold in thicknesses of 45 mil, 60 mil and 90 mil. In Indiana, we typically see 45 mil and 60 mil specified. The thicker the membrane, the better the long term durability.

How thick is 80mpo TPO?

0.080 inch thick
WeatherBond TPO is 0.080 inch thick white, reinforced single ply roofing membrane. TPO single ply roofing is designed for all types of commercial and residential single-ply roof construction and re-roofing applications.

What is the minimum slope for a TPO roof?

Thermoplastic single-ply roofing systems are plastic sheets (PVC, TPO, CSPE) that are welded together with hot air. This creates a shingle sheet that provides the weather protection for the building. Both the Thermoset and the Thermoplastic must be installed at a minimum one- fourth-inch-per-twelve-inch slope.

What is maximum slope for TPO roofing?

The maximum recommended roof slope for Mechanically Attached Roofing Systems is 18″ in one horizontal foot. There are no maximum slope restrictions for the application of the Fully Adhered Roofing System.

Do you glue down TPO roofing?

A TPO roof can be installed fully-adhered, mechanically-attached or ballasted. When the TPO roof is fully adhered it means that the membrane was glued to the substrate using a special strong adhesive that creates a chemical bond with the TPO.

What underlayment is used for TPO roofing?

TPO roof insulation in the Midwest is typically polyisocyanurate board insulation, also referred to as polyiso or just iso.

Is TPO good for flat roofs?

TPO (thermoplastic polyolefin) is a single-ply white membrane used in both commercial and residential roofing. Due to TPO being a white membrane, it reflects heat instead of absorbing it. If you have a flat roof or a low-slope dormer over a bedroom, TPO is a great option because it’ll keep the room below cooler.

What is Thickness over scrim?

Thickness Over Scrim is a measure of the thickness above the reinforce- ment fabric of the weathering layer. Membrane manufacturers put sta- bilizers into this top layer to provide resistance to UV and heat-initiated degradation.

Can TPO be used on sloped roof?

TPO can be used on both residential and commercial roofing systems. It can not only be used on flat roofs but low sloped roofs as well.

How good is TPO roofing?

In reality, the thickness of a TPO roof has no impact on its quality or durability. Again, since TPO roofs are so new on the market, there is little evidence and research done to say how long this type of roofing membrane will last. Generally, roofing experts estimate a TPO roof will last 10 to 20 years.
