Alumawood IRP Roof Panel

Alumawood insulated roof panel

What is an IRP, or otherwise known as an “insulated roofed Maxx panel”?  Amerimax, AKA Alumawood, produces a patio cover roof that actually has high density foam insulation sandwiched between two pieces of aluminum. This foam insulated panel is what keeps the radiant heat from passing through the covers roof and then onto your skin.  Why is this important? Essentially, the radiant heat is what’s going to make you hot and uncomfortable while relaxing under your patio cover. The Maxx panel, Insulated cover reduces the heat transfer through the covers roof.  Other roof systems like for example, concrete tile or torch-down do little in the way of offering any resistance to this heat transfer.

Alumawoods R value of their panels

When you choose to install the Alumawood Insulated roof panel (Maxx IRP) in your patio cover believe it or not, you can actually feel the difference. How so you ask? Well to start off, the insulated high density foam panels are resistant to radiant heat as mentioned, which is nice when you’re trying to relax under your new cover enjoying your iced tea. There is a reason it’s called “Iced Tea”, and not melted ice, watered-down tea. Be that as it may… the “R” value defined is: “the capacity of an insulating material in this case foam, to resist radiant heat flow. The higher the R-value, the greater it’s insulating power”. This factor is directly proportionate to its materials overall thickness in many cases.

Wilki says it like this... “In building and construction, the R-value is a measure of how well an object, per unit of its exposed area, resists conductive flow of heat: the greater the R-value, the greater the resistance, and so the better the thermal insulating properties of the object.”

Why “R” Values Are Important In a Patio Cover Roof


Take into consideration, we’re just dealing with foam and not some other roofing material. What I mean is that we cant really achieve an “R” rating of 140R because we can’t manufacturer the panels at a thickness of 10″, that would look little weird. Panels supplied by Amerimax are 3″ in thickness and the R value for these panels hoover around *13.95R according to Elitealuminum products, give or take a few micro R’s.

Elitealuminum is one of the manufactures panels for Alumawood. It’s important to remember that the R is also related to the material used as a roof (Insulated, Tar-pitch, Concrete tile, Composition). The more dense the material the better insulating qualities it possess.

Let’s Try An Experiment… Wood vs. Aluminum

Compare the Alumawood insulated roofed panel to that of a concrete roof. How do you do that? Well, without specialized equipment like an infrared camera, it’s almost impossible. Granted, not everyone has a $20,000 infrared camera laying around, but we do.  With that in mind, we went out to perform a test of materials. understand that the day this test (pictured below) was performed it was in the middle of summer on a day that was amazingly hot. As you can see by the ambient temperatures (lower temperature on the scale), it was dang hot under these covers.

Fortunately for me, I actually have access to these two very different roof covers within 200 feet of one another. What makes this important?  Well, I wanted the test to be accurate so the closer the covers were, the closer the test thus the better overall results achieved.  As you can see by this test, the Alumawood cover was almost 20 degrees different on the surface. 

So if you’re in the market for a new patio cover and actually like Ice in you “Iced tea”, contact a patiocovered representative and we’ll get you a sample of this stuff… I’m sure you’ll agree that its not only beautiful to look at, comfortable to sit under, but saves ice.

“Sitting under these insulated panels is like sitting under the most shady-est shady tree you can find… Really.”

The Alumawood insulated cover is the flag ship of the entire Alumawood patio cover line up. Not only is this cover more affordable than wood, it will never cost you a single dollar in maintenance! Yes, you heard that correctly. Never again will you have to paint, primer, scrape, sand and basically loose about 20 pounds sweating your butt off in the middle of summer working on that tired 30 year old wood patio cover. Who needs to diet?

Everything you see in the attached image (above) is what the Alumawood insulated patio cover system is equipped with. 

  • Posts and post covers
  • Insulated panels
  • Panel attaching hardware
  • Side plates (on either side of the cover)
  • Gutter system
  • Wrap kit (pieces at the front of the cover that stick out)
  • Steel post inside beam (optional)
  • Beam 

And If All That’s Not Enough… Here Are Three More Reasons To Consider The Maxx Panels.

Reason #1

alumawood insulated panel

Easy-to-install locking system which easily snaps together during installation and increases strength and performance. Aluminum extruded gutter system – A thicker grade gutter system that provides superior life and performance. (Optional leaf guard available

Reason #2

Alumawood benefitsPainted aluminum embossed finish with 8″ Plank Design – Although the material is aluminum, it’s still a durable dual layered system which provides a superior finish. Not only is it a durable finish, but it resists scratches, corrosion and fading. It also requires less maintenance than most other finishes.


Reason #3

Alumawood MAXX panelsIntegrated Aluminum Fan Beam Option:
The fan beam is an aluminum channel which runs through the center of the Maxx panel and provides a means of fan attachment to the panel seamlessly. Of course, this channel is made of extruded aluminum and is surrounded on all sides by foam for better lamination and to reduce telegraphing.


Lights for Solid Roof Patio Covers

Recessed lights are absolutely an option for solid roofed patio covers. Alumawood used to carry these really cool light bars they called “light strips”. Light strips consisted of an all aluminum housing that fit between the solid roof panels. It housed 3 LED lights at 700 lumens each. Amerimax, aluminum patio cover manufacturer has since discontinued manufacturing these lights. Now, if you would like lights in your solid roof aluminum patio cover we use Disk lights. These lights are also 600-700 lumens and install quite easily and are just as affordable as the older light strips.

Do Alumawood Insulated Roofed Covers Require Building Permits?

Most all cities in Los Angeles and surrounding counties require building permits for patio covers. With this in mind, it’s safe to say that some jurisdictions are more difficult to work within than others. For example, in Santa Clarita we have both Los Angeles County Building and Safety as well as the City of Santa Clarita’s building and Safety Department to work within.

Of the two, in my opinion, the Santa Clarita rules are less stringent than compared to LABS for the Alumawood insulated roof panel as well as wood patio covers. As a matter of fact, in the Santa Clarita Valley, the MAXX panel insulated patio cover is not permitted to be installed within the Los Angeles Counties jurisdiction.

How About Patio Cover engineering?

Amerimax seems to have thought of everything, including engineering. Opposite of wood, Alumawood products come pre-engineered. Even if you choose to purchase a patio cover kit in Los Angeles, it’s still engineered. So how it works is this way… Amerimax had their patio cover systems (all) engineered for minimum installation specifications. no matter what your situation is, there’s an engineered prescription for that install. So fear not. Unlike the Alumawood counterpart, wood, there are no extra fees for engineering here. And if you though it couldn’t get any better, this comes at a savings of up to $500 to $3000.

DIY Patio Cover Kits…How Easy Are They to Install?  

Can you hard-boil eggs? Installing an Alumawood patio cover kit it just that easy. Okay, it’s not as easy as boiling an egg. Come to think of it… I hate eggs.
