/diy/ - Do It Yourself

DIY, just need a respirator and suit. rent machine from home depot. they will show you how to use it.

Just add some blow in

>>1115575
the vacuum thing right? know of any regulations in texas for disposal of the stuff? laying is as simple as placing it down right?

>>1115576
doesnt blow in have an r value of 6 or something? id settle for min 12.

>>1115577
Put it in bags and take it to a landfill re re

>>1115582
oh sounds easy enough. and the newer non blow in stuff just places on the roof boarding right? ive seen some with the insulation going up the top of the roof. i dont have an attic set up with a crawl space so idk

>>1115590
Yes the bats fit right in you probably will have to cut them with a blade its pretty straight forward try and place them so theres a little arch in them like a bring youtube is your friend

>>1115627
*like a bridge

>>1115577
>should i remove and install insulation myself?
What is it made out of? Same of the older stuff was quite nasty. You might be dealing with asbestos. And since I have said the Word that shall not be spoken, queue a parade of people arguing about how many days you have left to live for being near the stuff.

> the removal seems like a hassle
Yep.

> and i have no idea how to put insulation in.
Youtube is helpful. What kind of insulation were you looking at using? Blown in? Rigid? Fiberglass batts? Something else?

>know of any regulations in texas for disposal of the stuff?
Texas? Shit son, just dump it in a park or in a school or something. Don't they hand out medals over there for damaging the environment? As long as you don't dump it on someone that has any money or power you'll be fine.

house is 15 years old and the stuff was white, i know its not asbestos because one of the terms of sale was a guarantee that the property and its fencing contains none.

looking at bats, it seems like you just place them in there but ive seen some people place them on the angled part of the house so as to cover basucally under the tiles.

im also probs the most eco guy in texas, my neighbours call me a hippy because i have solar panels

>>1115580
The deeper it is the higher r value you get.

>>1115660
oh true, didnt think of it that way

>>1115657
>one of the terms of sale was a guarantee that the property and its fencing contains none
That doesn't mean they could've missed something. But unlikely.

>>1115697
basically they just payed an inspector to check everything. i thought asbestos was out of use since the 80s?

Plumber I know said a water tank in the loft split because there was too much insulation and it was too cold. Apparently the water took out two floors and fucking ruined everything.

>>1115561
What kind of insulation is that? In my country we usually use mineral wool (which I'm not exactly stoked on replacing on my attic this summer...)

>>1115776
Looks like fiberglass blow in with a healthy coating of dust.

>>1115697
>That doesn't mean they could've missed something. But unlikely.
if your inspector missed hundreds of square feet of blown in asbestos containing insulation in texas you have the right to shoot him in the face with your state mandated shotgun

I have eternit roof shingles on my house. They were laid some 40 years ago, and is practically damn near impossible to wear down. But because they contain asbestos I'm not allowed to clean the roof without having it done by specialists, and when I'm going to replace it (which will be within 5 years), I'll have to store the shingles for god knows how long, as I'm only allowed to dispose of ten shingles a year...

>>1115794
Sorry, I noticed they changed the law on how many shingles I can dispose of. It's 500kg/year now, but it used to be 10 shingles.

wear a mask dude!

also after you remove the foam, buy a box of that spray foam expanding insulation shit and a grip gun with long nozzle for it.

Use that shit to spray between the boards, drywall sheets, light fixtures and any openings on the floor of the attic.

Take the extra step to do it right and seal that shit up to reduce drafts and create more insulation.

Also I've heard cellulose has better r value, but theres also the shit about it putting a house up in flames quicker.

>>1115561

If it ain't asbestos, no point in taking any out. Insulation is insulation, the more the merrier.

>>1117222
THIS

>>1117019
good tip, how flammable is the foam around lights? i have about 40 down lights in my house and 15 other lights

>>1117222
idk its gone pretty gray. most likely a fire hazard now. desu asbestos is over rated in terms of toxicity

>>1115776
somewhat related, but, anyone had any experience cutting that (mineral wool) shit?

obv. you can, as rolls need to be cut to length, etc. - problem, can get some for cheap, but would need to cut every roll up the middle, its way wrong size. Only experience, from memory, wasnt particularly pleasant to handle, but, cant rememeber actually cutting it, or someone else was.

Bad idea, or, a goer? would prefer the solid stuff, cant find cheap tho, and fuck that blow-in stuff, but, its all opinions, end of the day.

>>1117282
hows mineral wool different to glasswool?

>Blown Insulation

I've seen fiberglass, cellulose and recycled denim used as insulation. The thicker it is layered the more R value you get. If this is what you have now just fluff up the old stuff a little and add more to the top. I'm sure there's a chart somewhere that shows how many inches for x amount of R value

>Fiberglass/Mineral Wool Batts

Putting batt insulation between the ceiling joists is pretty retarded since blown in is so much easier and faster, but I guess it wouldn't settle as much. If you intend on putting it between the rafters and the soffit and ridge is how your attic is vented then you will need to buy those foam or cardboard baffles and install those wherever your roof sheathing is. This lets the air circulate through your soffit and out of the ridge vent and dries any moisture that condenses on the underside of your roof sheathing.

I've used the mineral wool insulation since its technically "fire resistant" for places that are a bitch to fireblock for code purposes, but Im not a fan of it for its insulation properties. We will use it on interior walls that have plumbing next to bedrooms or living areas or any room that needs sound insulation some times but nothing necessary for inspections.

I've heard it called mineral wool, rock wool, glass wool or just one of the brand names like Roxul.

I tell everyone that if you can afford spray foam insulation then that is your #1 choice, but it is pretty costly.

>>1117300
I dont think it is?, nor did I claim otherwise ;D AFAIK.. Think they all (mineral wool/rock wool/glass/Superglass/Rockwool/etc) all the same shit, probably dependant on locale what you use most, but I sure aint no specialist. But I see one above, who agrees..

>>1117309
Ta, was just cutting the stuff (rolls up the middle) was giving me second thoughts, but, if thats easy enough.. if I could just cut the rolls, while packed, be lot easier, but, they pretty damn big. RE: previous posts:

(a) guy complaining 'its gray' - loose stuff mostly all looks like that but (gray..) no?
(b) whats actually the stiff stuff called, like laid in blocks? Is that same? Dont want loose (personally) as want to use loft, be floored (obv.) but, that shit reminds me of polysterene packaging chips, gives me trauma.

Cheers! for info appreciated.

You never insulate beneath a CWSC in a roofspace

>>1117320

I wouldn't worry about it being gray colored. Most likely its just dust from the attic that has settled or that was just the color of the insulation. I've seen gray, white, blue and green-ish colors before, it just looks like that when its freshly installed too.

The insulation that is laid in "blocks" would be a kind of rigid foam insulation. polystyrene, polyisocyanurate or polyurethane closed cell foam that is sold in sheets (Typically). It has an R value of 4 or 5 per inch of foam but that shit can get expensive. I've only ever used it to insulate against concrete for basements or crawlspaces.

If you're wanting to make the attic a finished room then you need to insulate against the roof between the rafters using batts and baffles (Pic kind of related, but don't put gaps between them like this guy did.) The only problem you may run into using batts like this is if you cant properly fit enough insulation in the rafter bays to get the R value that you need. (R-30 batt insulation is pretty thick stuff) Then you're looking at furring down the rafters and all kinds of bullshit.
