Roof insulation.


To be fair, I do take that with a pinch of salt as it my be a competitor trying to steer you to buy a competing product but it still doesn't sit particularly well when viewed in light of their poor public relations highlighted above. Business owners who can't be bothered to update contact details on their site or chase down business leads raises all sorts of questions in my mind.
 
My installation wasn't done by ThinkGreen, but by an installer (InsulationExperts). The guy who I spoke to on the phone was the same guy who actually did the work (unlike many contractors I've dealt with who might seem very knowledgeable, but then they just dump a team of unskilled workers on site and disappear only to come back when it paying time).
He told me (as mentioned above, take it with a pinch of salt) that the guys pushing IsoTherm are actively degrading ThinkGreen on their websites / brochures cos of competition.
Wouldn't it be nice if one could test drive both for, like, a month and then decide? :)

I'm doing the installation myself so was planning on buying direct. I'd bet your installer has an established relationship with the Think Green guys and that makes all the difference. If was making use of an installer I'd probably still consider them as service becomes the installer's headache. But since I'm struggling so much just to get a quote out of them I can only imagine how tricky any after-sales will be should I have need of it.
 
Eco-Insulation=shreaded and treated newspaper.... awesome stuff, makes the roof look very neat (if that even matters) and gets into all the nooks and crannies..

Think Pink and Think Green work really well if you can lay it neatly enough under wires and pipes etc. Eco-Insulation just covers it all...

I was gonna go with eco-insulation. But I read some concerns that the eco-insulation settles and loses effectiveness over time. Plus my geyser is in my ceiling so there's a risk in my situation if the geyser were to fail catastrophically (even with a tray) or a pipe in the ceiling was to spring a leak (already happened once :( )
 
Mine was also done by insulation experts and I found the job to be very neat. I inspected afterwards and noticed that they laid it under all of the pipes and also insulated the pipes as well. They confirmed that their product is SABS 'tested'.

That slagging website is very underhanded if you ask me. If you want to dish it out at the competition don't do it so blatantly.

Does anyone have this SABS test report? I wanted to install this a year ago. Got a quotation and even an install date. When I wanted to see the SABS report, all communication ceased.

My 2c.

We should ask them for it or does the SABS have it on their site?

Putting the website review and quality of the product aside, the fact that I'm still waiting for a simple quote almost two weeks later speaks volumes about their service I'm afraid. That ultimately decided it for me.
 
So first 24hours post 145mm isotherm insulation. Can't say I notice any difference so far.

Have you warmed up a room(fire/heater/whatever)? Its a barrier, so, heat from roof/ceiling won't come through into room, the same way heat from room won't escape through ceiling. If a room is cold, it will stay cold until sun/appliances warms it up, then will stay warm, visa versa in summer, if you cool it, it will stay cool. At least thats how I understand these things.
 
Spunchem here in Durban does the Spunsulation.

Its really thin, light and weldable .....good stuff.

Also, if your windows allow air to travel through them when they closed (like in my case), then your room will stay cold.
Insulation is not just for the ceiling, you must ensure that your windows, and doors, shut tight enough to keep the wind out.

Yeah I understand that the insulation cant generate heat, only trap it. Measurements were done with no heating in the room as I wanted a pretty constant control. I was hoping the few heat emitting devices in the rooms, people/lights/cooking/gaming PC would generate and then trap enough heat to make a noticeable difference. But this has not really been the case.
Ill have to jump into the roof to have a look and make sure that everything is bedded down snuggly and that no gaps have been left.

Would love to do cavity foam insulation too, but seems that no one here does it. Also after reading up about all the youtube horror stories i don't think I would trust anyone locally.

You wont notice it immediately, i had my roof done middle of last winter, and it took a while before i did notice a rise in internal temp.
The installer did say it takes a while for the product to "settle".

http://ecofoam.co.za seems to do cavity filling?

there are (were) 2 companies in CT that did this kind of work. took me awhile to find them :(

my idea was to kill 2 birds with 1 stone! since the plastic lining that lies under the roof tiles rotted away many years ago and was causing minor problems with leaks, not to mention the costs of removing all the tiles and redoing the roof lining - I wanted the spray foam to cover & seal the tiles underneath permanently and provide thermal insulation.

1 company took the time to came and inspect my roof and bring samples of their foam product. the problem was that both companies made it clear that since it was extremely difficult to get their equipment into the small space in my roof and the fact that they will NOT spray directly onto the bare roof tiles for fear of cracking the tiles in summer. the idea was abandoned and I found roof insulation with a tin foil backing that prevented minor drops of water getting onto my ceiling thus solving the problem.


if you are building a new house or an edition then they will come spray foam before the ceiling is installed.

Im still apprehensive to pursue. Just look at the horror stories on youtube. Easy to get wrong and its not like roof insulation which you can just whip out. Im pretty sure my cavities are full of rubble and rubbish anyways. Uneven fill and you will have endless issue with damp, smells ect.

a cavity wall is pretty insulated to start off with. I also spoke to the spray foam guys about spraying foam into the gap - they say it's doable, just drill holes strategically along walls and pump the foam in.
