Commercial roofing insulation provides a vital thermal barrier between the roofing system and the inside of your building. Choosing the best insulation product for your needs reduces heating and cooling costs with a resulting impact on your operational budgeting.

Which commercial roofing insulation do you need? Let’s take a look at the types available from our vast network of building supply centers.

Mineral Wool Fiber Insulation

Mid-Atlantic Roofing Supply sources top-brand ROCKWOOL mineral wool fiber insulation in batts or boards. This stone-based insulation product works for various commercial roofing applications. It is known for being resistant to moisture and withstanding high heat, making it ideal for use in hot climates or on buildings with a higher risk of fire.

Expanded Polystyrene

Expanded Polystyrene (EPS) is a closed-cell rigid insulation made from polystyrene resins. The EPS product is made from beads of polystyrene that are heated and fused together to form blocks that can be used in a wide variety of applications. Air pockets in voids between the blocks provide superior insulating properties. This commercial insulation is very affordable and can be used in hot or cold climates.

Extruded Polystyrene

Extruded Polystyrene insulation (XPS) is pressed through a die to produce a large, continuous piece of smooth material with a closed-cell structure. XPS commercial roofing insulation has superior water penetration protection and is extremely durable. Mid-Atlantic Roofing Supply sources the DOW brand of XPS roofing insulation, and it is excellent for use in both built-up and modified bitumen and single-ply roofing systems.


Polyiso (Polyisocyanurate) is a rigid foam board insulation made of continuous closed cells sandwiched between two facers for superior air, moisture and fire resistance. Polyiso commercial insulation is available with different facers that all comply with ASTM Type II provisions and are suitable for all types of commercial roofing. Mid-Atlantic Roofing Supply sources Polyiso roofing insulation from top brands like ATLAS, Johns Manville, GAF, Firestone, GenFlex and R MAX.
