2 of 6 Replacing our Cottage Roof - placing insulation

Our cottage used to have a sod roof. Due to an infestation of carpenter ants, we had to remove it. After much research, we decided to go with P2000 insulation, which has an aluminum skin on the top and bottom. This gives it high insulative and reflective properties, resulting in an R54 insulation value.

I spent two weeks removing the sod roof (sod then layers of tarp then a single layer of black plastic then two layers of pink insulation). Once all was removed, I had to scrub down the remaining waterproof membrane since it was covered in ant remnants and bug spray.

Once all this was done, we were ready to replace the insulation, layer of black plastic, tarps, and cover the whole thing with 1 1/2" of 3/8" crushed limestone.

This is the story of that arduous task!

When not fixing the cottage, I'm a classical guitarist and composer. Compositions from all three of my albums can be purchased through CDBaby.com and most on-line downloading services (iTunes, Napster, Weed, etc.) Also, the guitars I use were all made by myself.

Oh....where in Ontario are you?

[GeraldBoyClassical]

The cottage is near Barry's Bay, about an hour east of Algonquin Park.

[Spartreeman]

So, are you from NY or vermont and this is in Que?

I like stackwall construction, and have use a similar material for insulation on a sauna.......

[GeraldBoyClassical]

Nope, we're from Ontario and the cottage is in Ontario. The Canadian head office for P2000 is in Quebec.

I had been kicking my self for not putting down this kind of insulation on a house whose whole roof was replaced. Then I saw someof these panels at home depot but they had a R factor of 15... so I didn't feel too bad... now that I read these panels have an R 54 rating I am again kicking my self.!!!!!!!!

[GeraldBoyClassical]

I did a lot of searching on the net, and spoke with the Sales Rep in Quebec quite a few times before deciding on the P2000. Don't know why your Home Depot would have the wrong R factor, bummer!

The R value is a shame, it does work but R20 it is not. Plus you can get the same crap at Lowes for 10 bucks a piece, which is quite cheaper. Buyer beware.

Ok Yes, I love that area, a nice height of land...our cottage is a couple of hours west and south of you, Carnarvon area.

I have to complement you on your cottage, its very beautiful.

I had an thought that I would build a stackwall sauna(a fleeting thought), we went ahead with a traditional frame building for it. Now that I see your building, I am kicking myself for not going that way!

[GeraldBoyClassical]

yeah, I must have changed shoes at least 50 times that week or Gerald would have made me sweep the roof again
