Hi all

We recently moved into a old house which had very old insulation- apparently also the one with fibre glass in it.

We subsequently removed it.

Now my question is, is it really worth replacing it with something else? Perhaps the latest version with no harmful substances in it?

What will happen if we just leave the ceiling as is with no aerolite? In our previous home we did not have aerolite. What is best practice?

Lastly , if you could recommend a installation company in Cape Town?

TIA!
 
Plan your changes to your new home carefully, in this case any new plumbing, electrical where it goes above the ceiling, get it done first if you can, then add the insulation. just easier and ought to save money.
Isotherm is one product
ps. you have a pm
 
Go 145mm isotherm.. it makes a massive difference.. made from recycled plastic, so is perfectly safe to handle.. I am also in cape town..

I made use of roof insulation and can recommend them.. supplied and installed, you are looking at around ~R 110/sqm depending on which thickness you go for..

You can certainly do it yourself.. though, if the trusses are not spaced the same width as the insulation, you are going to have a difficult time getting them cut to fit..

Also, to be effective, you have to get every single nook and cranny.. in my roof, you have to be on your stomach to reach the outer edges and I was not in the mood to break through my ceilings.. then there's having to schlep the insulation in to the roof.. by no means quick.. three experienced labourers took 4 hours to do my 190sqm.. I would have been man alone..

This is very true. Best to do once lights and wiring finalised

Lol yeah its quite a mission. Do you place it over or under the wires?
 
trusses are not spaced the same width as the insulation ; I measured mine, cut them outside, cut mine 80 cm and 40 left over. so place 80 and then 2 x 40. use a tool to place them fast and easy. I place two layers, so it is 100 mm high
 
My roof is full of fiberglass insulation. If you don’t fiddle with it, it is fine. It’s nowhere as bad as asbestos.

You definitely need some insulation. Isotherm is as good as fibreglass and you can also get chemically treated granulated paper which is blown in and has better thermal characteristics

In a new house I built, we used sisalation which is aluminised plastic. This is placed just under the roof and forms a better heat barrier

Also look at well-fitting doors and windows to avoid drafts. The next step is double glazing or safety-glass with an insulating layer

The builder said it was dangerous.. i think cos it had fibre glass and was very old

Fibreglass is still used today. In fact in terms of thermal and sound insulation its tough to beat. Isotherm is pretty close in terms of thermal but its no where near as good for noise.
 
Definitely does help, quite a bit.

Temperature not as noticeable but most definitely sound.

Don't suggest DIY, I'm a fairly handy Oke and I struggled and regretted doing just 2 rooms, if you do go this way, worth watching the videos online for some tips and tricks.
