Consumer Warning - roof iron insulation.

Recommended Posts

Hi to all, I am writing this to inform potential buyers of roofing iron with foam insulation (pictures attached) to do your homework before buying this product.

Here's my story.

After purchasing my new house I decided to build a carport for our two cars. I chose the color bond type roofing steel with foam insulation on the recommendation from a freind that it was a good product, as he had it installed on a patio area and was still OK after 5 years. The company I dealt with gave me a two year warranty on the insulation. After about 12 months I noticed the insulation had changed color from silver to a milky color, I didn't think too much of it at that stage as it appeared stable. After another 6 months had lapsed I noticed that some of the material was peeling off and showing signs of shrinking, as well as in some parts the foam was slowly disintegrating, similar to a bio degradable plastic (pics attached). I contacted the seller about this problem and they sent a representative to have a look. The guys that turned up took samples and seemed a bit nervous about the product, indicating something was wrong.

The boss of the company rang the next day and said they were sending the samples collected to the foam manufacturer in Bangkok. After about two weeks the representatives from Bangkok arrived to take a look. Well, here's where the BS started, Quote: This insulation is not for outside?? I asked so where is it meant to be used and why did the local company sell this to me knowing it was for a external carport, quote: It is for inside, I asked inside where, Quote: No answer. Quote: Your roof has not got a high pitch for run off, the water has got in. I said, that's funny I have never a drop of water under this roof since construction. I maid sure that all roof screws where placed correctly and water tight. Also the roof had a 200mm drop from one side to the other over a 5m span. All sheets were overlapped as standard practice.

The foam company reps then went to see the local company where I bought the roof steel, after about 2 hours ,we had a phone call from the boss of the local company to come and see them. 

The outcome from the meeting of the two parties involved, was that I had two choices: 1. They would reimburse me the money for the foam only and, 2. The local roof iron company would replace the old foam for new foam. Removal and installation of the roof iron was at my expense. Well, if you have any knowledge of installing roof iron and then try to replace the same iron on a roof you will understand why I chose not to do that. Instead, I chose to be reimbursed for the foam as it would be easier to line the under sided of the carport so that the foam is sealed and out of sight.

In conclusion, I cannot conceal the name of the local company as I agreed to be reimbursed for the foam, and I was unable to get the name of the company from Bangkok. The local roof iron company did admit that had changed foam companies in the last two years and now are considering changing to another company.

So, the best advice I can give is do your homework before purchasing this product, check with other expats that have used this product and where they purchased it and what was the warranty, like anywhere in the world their are dodgy operators selling inferior products. This faulty product has now cost me almost double the original cost to rectify the problem. I live in the Mukdahan province and If you are thinking about purchasing this product PM me for more info.

Be warned.

That last photo does look a bit like water damage ?..still water shouldn't damage the foam..

I could understand damage from strong sunlight ( UV ) 

or a bad reaction between the foam and the glue used to stick it to the metal sheets.

I did mention to them that man made foam can float around in the oceans for hundreds of years, got a blank look. TIT.

Disappointing situation you found yourself in. As you mentioned, lining the underside is probably the best way to seal it all in.

 

Will you run ceiling joists from the supports and then fix the ceiling material to them?

For just a car port I wouldn't bother with any backing at all since its not an area you are going to be sitting under yourself. Still, hindsight is a wonderful thing.

Definitely a bad product if roof area is in the direct sunlight all day.

I would disagree. With nothing the underside is going to be radiating heat Into your car at a toasty 60+ degrees (middle of the day with it is going to be 23+ degrees cooler

 

Strange. Must be hotter where you are. Our car is parked under the car port which has metal roof, no backing. The area is well ventilated though. Getting in the car at mid day it doesn't feel that hot and the thermometer on the wall just says 38

( compared to 28 in our living room which as no air con )

Maybe the hot air rises or gets blown away, who knows.

 

Now if when shopping at Big C I have to leave it parked under the sun for 40 minutes ( limited shaded spaces ) , then when I get back to the car it really is toasty !!

I think your device is reading the surface temperature of the roofing material not the ambient heat

If you read what I posted you would understand that that was exactly what I said

Radiant heat is not ambient heat 

 

Ambient heat has a very loose relationship to radiated heat. Just stand in the shade of a tree at 7 am on a sunny morning now then step out into the sun.

Basically yes to your questions, I have found a light weight material that should do the job.

Unless the underside is black, very little radiation transfer will be occurring. The main mechanism of heat transfer will be convection. Provided the carport is well ventilated, convection would not be an issue.

Why do you think builders install soffits and roof vents?
