Nord Bitumi has manufactured polymer-modified bituminous (APP, SBS, PAO) roofing and waterproofing membranes for more than 50 years, with products certified by more than 20 international testing institutes including FM, Miami-Dade, UL, and ISO 9000. The membranes are engineered to perform across extreme climate conditions, from Norwegian cold to desert heat, making them a durable option for commercial low-slope roofing.
Engineered for Extreme Climates
Nord Bitumi built its reputation modifying distilled bitumen with high-quality polymers — SBS, APP, and PAO — to produce membranes that hold up across dramatically different environments. The company has tested its systems against everything from the extreme cold of Norway to the subtropical climate of Hong Kong to the wide temperature swings of the Algerian desert.
With more than 300 standard membrane types and the ability to manufacture to precise specifications for particular markets, Nord Bitumi offers contractors a level of engineering depth beyond a standard off-the-shelf modified bitumen product.
Multiple Polymer Chemistries
APP, SBS, and PAO modified formulations let contractors match membrane chemistry to the job's climate and performance requirements.
Internationally Certified
Agrément certificates from over 20 institutes, including FM, Miami-Dade, FBC, UL, and ISO 9000:2008, back the product line's durability claims.
Reflective Granule Options
Surface granules on certain membranes reduce roof temperature and protect against UV damage while improving appearance.
Product Lineup
- APP-modified membranes — plastic-modified bitumen for high-heat resistance applications
- SBS-modified membranes — rubber-modified bitumen for flexibility in cold and variable climates
- PAO-modified membranes — specialty polymer formulation for targeted performance needs
- Granule-surfaced cap sheets — ASTM D 6222 Type I, Grade G and Grade S rated options
Where It Fits on the Job
Nord Bitumi is a strong option for commercial low-slope roofing where climate performance and certification are priorities — particularly on jobs requiring FM, Miami-Dade, or UL approval documentation. The range of polymer chemistries also means contractors can spec a membrane suited to a building's specific thermal exposure rather than a one-size-fits-all product.

FAQ
What's the difference between APP and SBS modified bitumen?
APP (plastic-modified) bitumen generally offers better high-heat and UV resistance, while SBS (rubber-modified) bitumen offers greater flexibility in cold and variable temperatures. Nord Bitumi manufactures both, plus a PAO polymer option.
Is Nord Bitumi approved for hurricane-prone areas?
Nord Bitumi products carry certifications from more than 20 international institutes, including FM and Miami-Dade. Confirm the specific certification for your product and application with our counter team.
Is Nord Bitumi available at Murphy's?
Yes. Nord Bitumi is one of Murphy's stocked manufacturer lines. Ask our counter team which membrane types are on hand at your location.
