Commercial Roof Insulation

Membrane roofing systems are precisely that, systems. The membrane is crucially important, but so are the other components like vapor barriers, fasteners, and particularly insulation. Installers and designers must not ignore appropriate commercial roof insulation since the right choice will save on utility bills, and the method of installation could influence the life of the roof.

What Exactly Is Commercial Insulation?

Commercial roof insulation comprises a layer of material that is installed underneath the membrane to form a thermal barrier between the outside elements and the interior of the building. Roof insulation is critical since it reduces heating and cooling costs for both commercial and residential buildings. 

The aim is to constrain thermal transfer between indoor and outdoor temperatures. Insulation for commercial building roofs is more of a concern in areas that are subjected to extreme climate (cold or hot) fluctuations. The more you spend on regulating your building temperature, the more you should think about installing the appropriate insulation and the correct R-value initially. It can offer noticeable energy savings.

Kinds Of Commercial Roof Insulation

There is a wide variety of available roof insulation materials, and they range in R-value, installation methods, material type, and manufacturers. A skilled contractor who specializes in building supplies Adelaide should be able to advise you on the best commercial roof insulation for your application. Here are some of the most widely utilized commercial roof insulation types:
  • Fiberglass
  • Mineral wool
  • Spray foam
  • Expanded Polystyrene (EPS)
  • Extruded Polystyrene (XPS)
  • Polyisocyanurate (Polyiso)

Performance Of Industrial Roof Insulation

Commercial Roof Insulation Is Installed Directly Below The Roof Membrane, And Installation Is Contingent On The Roof System As Well As The Manufacturer's Recommendations. Insulation Can Comprise Of A Variety Of Materials That Can Range From Rigid Board To Insulating Concrete Or Liquid Applied Foam.

Key Considerations When Assessing Insulation Include:

Thermal Resistance (Insulation R-value)

R-value refers to the measurement of how well a layer of insulation can contest the flow of heat. The R-value of a commercial roof considers all of the layers within the roof system. However, the insulation layer will add the most R-value to the building. The higher the R-value, the more efficient the material. Bear in mind that the R-value of material will degrade with time when the material ages. Besides, adding too much insulation may lower the stress on a roof membrane through the influences of thermal shock.

Impact Resistance And Insulation Durability

Durability is an essential part of outdoor materials and commercial roofing entirely. Insulation impacts the resistance of a roofing system and must be able to resist the impact conditions of the rooftop location. The impact resistance for commercial roofing insulation is a continuing development within the industry due to more current performance standards. Appropriate system design and insulation selection are crucial to the roof system’s impact performance on debris, hail, and other falling objects on the roof.

Fire Resistance

Fire-resistant roofing materials can be fundamental in fire prevention as well as limiting the damage caused. Proper certification and fire testing are predominant in ensuring a roof is protective, safe, and long-lasting. When choosing a fire-resistant roof system, it is generally recommended that the desired system has an FM Class 1 rating or UL Class A fire-resistance rating.
