These roof systems are constructed with layers of felt and bitumen that provide a redundancy of durable protection.
Mod bit roofing system.
Bur roof systems have been utilized for over 100 years in the roofing industry.
Available in a variety of thicknesses in smooth and granule surfaces sbs membranes may be installed in hot asphalt cold adhesive or may be heat welded.
Wind uplift is a primary concern when installing a retrofit single ply roof system rsprs over a structural metal panel roof.
Mb roofing systems are a durable weather resistant type of low slope roof.
These hybrid systems are specified for certain situations and are typically comprised of two or three hot mopped glass fiber felts followed by a modified bitumen cap sheet.
Benefits of bur and mod bit time tested defense.
Astm e 1592 physical testing was performed on three test roof assemblies in order to determine the wind uplift resistance of an rsprs installed over existing structural metal panel roof systems fastened directly into purlins.
Mod bit cap sheet.
Sa sbs cap sheet membranes are specially designed for applications where the use of hot asphalt cold process adhesive or a propane torch is undesirable.
The ceramic coating promotes excellent long term adhesion.
A built up roof for example will typically include the built up membrane itself with or without gravel as well as some kind of insulation.
Tpo single ply roof systems range between 40 80 mils in thickness while most self adhered roof systems range from 180 380 mils making self adhered systems less susceptible to puncture from foot traffic.
Specifically engineered for optimal embedment in the modified asphalt sheet.
Firestone sbs modified bitumen roofing systems incorporate a synthetic rubber based technology which yields exceptional flexibility even in extremely low temperatures.
Hybrid systems include a very small specialized category of low slope commercial roofing systems using a combination of mod bit and bur.
Applications include new roofing recover retrofit and bur repairs.
Mod bit roofing mb is a shorter way to say modified bitumen roofing.
This system must be installed over an acceptable base sheet roof insulation or other suitable substrate.
Note that roof systems typically include more than one type of material.
Mod bit bur hybrid systems.
Epdm rubber metal tiles asphalt shingles modified bitumen asphalt bur pvc copper panels roofing slates and cedar shingles.
Dynatred and dynatred plus can be installed over built up and modified bitumen roofing systems to provide an integral skidresistant walkway for demanding service access needs.
Even with multiple layer installation the labor associated with self adhered mod bit roof systems is lower than tpo roof coverings.
