Question doghouse insulation?

Hi, what kind of insulation do I need to use on my doghouse cover? That, and how do you secure it to the cover? The previous owner just had regular pink house ins that just laid on top of the 454.... Not good IMO.

You are right that the engine needs airflow around it to keep it within operating temps...and parts like the plugs and manifolds are not cooled by the raditor water...very important to not cover it with insulation.

So what to do? The floor and dog house need a layer of insulation for heat and noise...Dynamat is an all in one product specifically for this purpose...see:
Introduction

The problem is cost, but it comes highly recommended.

I'm sure there are DIY ways to do this too...maybe if you afix aluminum foil to a layer of insulation, cut the material to fit the underside of the dog house and glue or screw it down(?).

Best luck

If you can find a commercial metal duct fabricator in your area, you may be able to by duct liner insulation from them. This material comes in blanket form in thickness from 1/2" up to 2" and has a coating on one side. I'm not sure how you would secure it. The duct fabricator may have some stick on insulation support pins that would hold it to the sides and lid of the dog house. In metal ducts, the insulation is glued on and then is pinned on with GripNail fasteners or similar retaining pins.

Heat shield

Heat Protection and Panel Insulation - Design Engineering Reflect-A-Cool


We have used and sold this product in a lot of different applications.

Might be good for doghouse. Easy to install and does great job with heat. Can not vouch for noise, but should help.

Instead of Dynamat you can buy the same thing called Fatmat on ebay for 1/2 the cost.

Thanks Scarab0088, Dynamat would be my first choice.. If iI could afford it, but it's a bit to spendy for me right now.

I would prefer something DIY, like phays mentioned. I never even thought of asking a HAVC person about it, I have a friend who is a HVAC contractor... I Never even thought to ask him!

I had never heard of Fatmat.. the prices are a lot more budget friendly

10 Sq Ft Fatmat for $25

Thanks for the help everyone!

the best thing ive found is DIY bedliner from duplicolor. I had dynamat... and the adhesive did not like the humid FL weather or extreme engine heat radiation.
I put 6 coats of bedliner on the fiberglass shell... no problems or issues. I would only use dynamat or similar products on the inside of the coach... like under the seats/carpet in addition to the padding for the best results.

Just did mine this past weekend using 3/4" "Hoodliner" Dynamat from Summitracing. Had to do it in pieces make sure you get the aluminum tape for seams. I had some on hand.

The old insulation was foil and fabric and the mice had made a nest in from the previous owner.
