Hi,
Wondered if anyone had any experience with "Thermilate"?

We are thinking of using it for our ceiling and external rendering.

We are thinking of using it for our ceiling and external rendering.

We used a heat reflective paint on our roof (in this case Astec EnergyStar) but in retrospect it was a bit redundant considering we also had reflective foil under the roof and in the wall cavity as well.

They all work on the same principle of reflecting radiant heat. The main advantage is in reducing daytime solar radiant heat gain then winter convective heat loss.

If I were you I would just use a combination of foil and bulk insulation. It would be more cheaper and more effective.

I modelled the effects of charcoal roof, white roof, reflective foil and heat-reflective paints:

Before you fork out hard earned money on the product I think you should look at the similarity with a product that can be bought at fiberglass shops called microspheres or Q-cell or microballoons. I wouldn't be surprised if they were the same thing and sourcing it through the fiberglass shops like FGI or similar can be far cheaper than the snake oil prices that some other sellers charge.

There seems to be a general level of disagreement on its effectiveness also. I don't know if it is agreed that the product really does everything that some claim of it.

I would only consider heat reflective paint if:

a) You can't put foil under the roof e.g. cathedral ceiling
b) You don't want to paint the roof white (aesthetics, council regulations)

If you check out the Astec website they provide independently evaluated technical data on their product (+ testimonies).

Thanks everyone for all the advice.
I've become increasingly sceptical about the merits of thermilate. I found some more feedback from some UK forums and they have come to similar conclusions as you all have.
I've decided to bin the idea of thermilate and stick with more "bread and butter" modes of insulation.

It’s right to be sceptical. This video breaks it down.
