Tpo Roofing Cover Board

Short for thermoplastic polyolefin tpo is a single ply roofing membrane that offers excellent performance at a cost effective price.

Tpo roofing cover board. Get to know more about one of the most popular commercial roofing systems get started. Without a cover board the roof is missing added durability. We reinforce our membranes with a polyester fabric and manufacture them using an ultraviolet resistant thermoplastic polyolefin formulation. Cover boards have historically had two uses.

This gypsum cover board is enhanced with a coated glass mat facer that achieves fm vsh approval rating with adhered 60 or 80 mil smooth back jm tpo membrane and standard jm tpo membrande adhesives when 4 x4 panels are adhered in low rise foam adhesive using the ribbon application with 12 o c. Heat welded seams provide superior strength. Hail is damaging to insulation but by using a cover board the impact is minimized. In addition national roofing contractors association nrca has issued bulletins over the years recommending the use of cover boards to minimize damage to polyiso.

Tpo insulation and cover boards learn about tpo insulation and cover boards. Insulation thickness must meet the energy code which is verified during the building envelope comcheck. Tpo roofing systems are made up of a single layer of synthetics and reinforcing scrim that can be used to cover flat roofs. To prevent blistering with built up roof membranes bur and to provide a separation layer and flat surface in re cover situations.

The building is more susceptible to hail fi re and wind damage. Tpo roof insulation in the midwest is typically polyisocyanurate board insulation also referred to as polyiso or just iso. Superior dimensional stability over competitive gypsum fiber boards is due to their low coefficient of thermal and hygrometric expansion. Shown to withstand delamination deterioration warping and job site damage far more effectively than paper faced.

Densdeck boards are an excellent substrate in most reroof applications and may be used with mechanically fastened or fully adhered rubbergard epdm or ultraply tpo roofing systems and are compatible with modified bitumen and bur systems in certain assemblies. R value is the measure. Thermoplastic polyolefin is a single ply roofing membrane that is one of the fastest growing commercial roofing systems on the market. Tpo s long term heat uv and natural fungal resistance plus flexibility without need for plasticizers also make tpo a reliable low slope roofing system.

Insulation damage results in a reduction of the roof s thermal resistance or r value.
