Thermalmix - Insulating Paint Additive

I have an outside wall that allows too much heat in during our summer days. Since taking the wall apart and adding insulation is too expensive, I tried painting the inside with the recommended two coats of Thermalmix Insulating paint additive. I added it to the tan paint I wanted in the room. It mixed very well. It coated very well. It was easy to paint. Since it is a bit thicker it goes on easily and dries quickly. And most of all -- THE ROOM IS COOLER! It is about 7 degrees cooler this summer. I am considering painting the outside of that same wall with this insulating paint this Fall. I didn't even know such a thing as insulating paint existed. I have shared my findings with all my friends and now with you. If you need some help with a warm or a cold wall I highly recommend Thermalmix Insulating paint additive.

We used Warmcoat (which had the "insulating" paint additive) on the north west facing wall of a shower-room of a country cottage that was suffering very severe mould. The room is only heated when used for occasional showering and it also contains a toilet with open pan. The effect was dramatic. It took months for any mould to reappear and this was easily dispersed by bleach and a further coat. The shower-room is in an outhouse with single thickness brick wall and insulated plasterboard which was unsuitable for further insulation. The two spaces are much easier to heat and stay warm longer. I was interested to see whether good results could be obtained in more traditional constructions and bought several batches of Thermilate additive for people in my neighbourhood to try. We suggest they paint a section of wall and we will go back to compare the temperature of wall of similar exposure with or without the additive bearing in mind that radiation loss increases as the fourth power of the temperature difference of wall and adjacent air. Still investigating but expect the results to be far better than the sceptics suggest. The paint is dear but the powder additive alternative at under £20 to put in a 5 litre can is well worth a try and will not suffer the cold bridging problems of some the more approved methods of insulation. Just paint right to the edges of the room. Thermalmix - Insulating Paint Additive We found the finish was a bit rough and you would need another coat of emulsion for a smoother finish.

This may help more in the winter. Not seeing enough of a difference to invest in more. It does make it more reflective and thinner. Just not seeing that it helps. 3 and a 1/2 stars so rounded up as I may be wrong and it's helping more than you can feel. It's very easy to work with. Doesn't clump. And gives the paint a shimmery texture. I did not notice a smell. Cannot speak to durability but it does seem like high quality

We haven't endured a winter yet since using this paint additive so it's hard to say whether it will reduce our energy bills at all. I will say however that the walls where I have used the paint with the additive certainly feel considerably warmer to the touch than the walls without. (we have asked various visitors, builders etc to touch the walls and all have agreed that where the additive has been used the wall is mysteriously warmer!) It's not easy to mix manually so I would recommend a mixer attachment for your drill, the paint finish feels slightly rough with the additive (as if you'd put very fine salt in the paint!) but I actually quite like the rustic feel. It does change the colour of the paint slightly so I painted over with another coat without the additive. All in all very pleased with the product!

I applied to to ceiling and really block out this Texas heat the house is cooler now
