What are insulated roofing panels and how do they work?
Insulated roof panels are insulated metal panels that can be used to cover an existing flat deck, or they can comprise the entire roof system itself. They work by providing a continuous layer of insulation in the whole roof platform, preventing heat transfer through conduction and convection.
Insulated roofs are designed for three basic types of installations:
Retrofit-over old flat decks
Replacement of an existing deck with a new fully-insulated roof
In a flat-deck installation, an insulation board is fastened to the roof joists from below, between the joists. In some cases, solid sheathing may be required for fire protection or structural reasons.
In replacing an existing deck with a new fully-insulated roof, an insulation board is installed against the underside of the existing roof structure to provide a continuous layer of thermal insulation across the entire platform area.
Longitudinal venting channels are provided through the panels at ridge and eave positions to ensure that any heat absorbed by this thermal storage media will be directed outside before its release at night. Asphalt shingles should not be applied over these panels to avoid trapping moisture in them during hot summer conditions.
The Benefits of using Insulated Roofing Panels are numerous.
They ensure a high thermal resistance for the entire roof platform area. They provide a fully sealed, watertight installation that is more durable and longer-lasting than traditional flat-decking systems. In addition, there is no need for secondary containment or waterproof barriers to prevent leaks on an adjacent deck below.
Insulated roof panels consist of a W-shaped corrugated steel channel with pre-fabricated polyisocyanurate insulation inside the channel, which acts as the primary insulator between the structure and weather elements of wind and rain at all times throughout the year.
Pros and Cons of using Insulated Roof Panels
The advantages of using insulated roof panels are that they provide the best thermal resistance for your roof. There is no need for secondary containment or waterproof barriers to prevent leaks on an adjacent deck below.
The disadvantages are that the initial cost may be high, you cannot walk on them after installation since they are not meant to support weight, and in some cases, solid sheathing may be required for fire protection or structural reasons.
Which type of insulation is best for your home?
Insulated roof panels are the best option if you typically have summer/winter temperature swings of more than 10°C, especially when your heating costs are twice as high as your cooling costs.
If your home is in an area where temperatures fluctuate by less than 5°C throughout the year, spray foam insulation may be a better choice for you. If you prefer a more affordable option, fibreglass insulation might be a good choice.
When is insulated roof panel installation recommended?
Insulated roof panels are a great option if your home has an existing flat roof or you plan to start from scratch. Installing the panels as a new construction provides permanent and continuous insulation and results in higher energy savings than using other types of insulation such as spray foam or fibreglass.
If you have an older flat deck with asphalt shingles on top, it may be more affordable to use insulated metal panels for retrofit-over old decks. This saves costs by keeping the same roof structure and replacing only the insulation instead of completely re-decking the roof platform.
What materials are used for installed insulated roofs?
Insulated metal roof panels come in steel, aluminium alloy, or galvanized steel. Polyisocyanurate insulation is used to provide the best performance in thermal resistance.
Most of the time, insulated panels come in a galvanized steel finish. It has been proven to be more durable and longer-lasting than aluminium alloy or painted steel finishes. However, aluminium alloy is gaining popularity due to its lighter weight, ease of installation, affordability, and longer life span compared to steel.
There are also insulated metal roofing panels with an EPDM rubber membrane on top instead of standard asphalt shingles for low-sloped roofs. The membrane serves as the waterproof barrier for this type of panel over another material such as Polyisocyanurate (Polyiso), a closed-cell, rigid foam board insulation or modified bitumen that can hold moisture against the roof deck.
Garage door insulation kits are available commercially, which seal between joists with pre-insulated steel channels to provide an insulated, watertight and draft-free space for storage above your garage. They come in different depths, and standard widths and typically have pre-drilled holes every foot that can easily be connected with self-tapping screws or nails.
Where are Insulated Panels Commonly Used?
Most insulated roof panels are used on low-sloped roofs or flat decks but can also be used on steeply sloped roofs. They are typically installed on refurbishments, new constructions, repairs to rusty steel decks, garages and warehouses.
Compared to traditional insulation materials such as spray foam or fibreglass batts, the insulated panel is more cost-effective since it acts as an insulator and provides wind resistance that prevents noise from entering the space below it.
What’s The Difference between Insulated Roof Panels and Other Insulation Materials?
Insulated roof panels provide thermal resistance due to its core of polyisocyanurate insulation which acts as a high-performance building envelope. This type of insulation can retain high R-values for a longer time than other insulation types, such as spray foam, which provides less air infiltration.
Insulated metal panels are also better suited for roofs with a low pitch since the panels are only made in standard widths and lengths. In contrast, multiple pieces of insulation material are needed when using thicker materials.
How Do I Measure For Insulated Roofing Panels?
Determining how many panels you need is simple. There are standard dimensions measured in feet or inches that your contractor should refer to if you don’t want them to measure it themselves, but if they’re willing to, please request that they do so because it will give you peace of mind knowing that everything has been measured correctly.
To measure the height of each panel, you’ll need to define the distance between your rafters before shopping for panels. If it’s a steel roof deck that has visible beams or framing that can be securely fastened to, then measure the height of all four walls together and divide it by however many feet you’re planning on using per panel.
For concrete decks with no support structure underneath them, the insulated metal panels should have insulation supports which are usually about 3 ft apart depending on specific brand specifications.
If you are making multiple cuts (angle cuts) at various spots across your wall, make sure to measure these as well, so they don’t end up being too short. Contact local suppliers in your area to help you determine the right size and quantity.
How Much Does Insulated Insulated Roofing panels Cost?
The cost of insulated roof panels depends on a variety of factors such as what type of insulation material is being used, how much it weighs, how big the order will be and other variables that should be discussed with suppliers in your area to get a quote from them based on your specific project requirements.
For example, if you needed 120 meters of regular steel deck panels for an average-sized garage, expect to pay around $300-450 depending on regional labour rates and the number of screws or nails required per panel. Polyurethane sprayed foam insulation panels typically cost more since they are a higher-end option but need fewer panels overall.
