    Insulating Paint Additive,Cuts Heat Loss, Stops Mould

    Thermilate Insulating Paint Additive Reduces Heat Loss in Your Home or Property through INTERNAL, EXTERNAL WALLS  CEILINGS

    Having been featured on several TV programmes such as BBC'S TOMORROW'S WORLD, Changing Room, THERMILATE, the revolutionary, durable paint additive that makes paint insulate is now available to home owners, maintenance  painting contractors.

    This very practical product can be added to virtually any kind of paint… from interior emulsion, exterior masonry paint, gloss paint on steel, you name it. In all cases, it will reduce heat loss out through the substrate.

    AND… it also works the other way around, if you wanted to keep heat inside pipes, hot water tank etc, the Thermilate additive reduces heat loss when 2 or 3 coats of treated paint are applied to the pipe etc.The two images on the right aboveshows Thermilate used in oil based paint on inside of a steel barge to stop / reduce condensation on the steel walls.

    Steel Roof Condensation

    Another handy application we have been told about which gets excellent results was where condensation occurs on underside of a steel roof, also known as steel roof condensation such as commonly found on corrugated steel, sheds / workshops, steel containers  so on. In this scenario, the handiest option is add the Thermilate to any appropriate paint and apply a coat or better still two coats.

    Idea is to apply 2 or 3 coats of any oil based paint with one bottle of Thermilate per 5 Litres of paint.


    Saves on heating bills because less heat / energy will be required for the same results.

    Reduces or eliminates mould on 'cold walls' etc

    Helps reduce condensation / damp wall problems

    Customer Comments Below:


    Thermilate Insulating Paint Additive can be used in conjunction with our Warmcoat Advanced… Use the Warmcoat for the first two coats and add the Thermilate Additive to the final COLOUR coat.

    Available in 1 litre bottle – enough for 5 litres of any paint.

    "This is now the 2nd winter my 'Thermilated'  bathroom walls and ceiling are experiencing and I have waited until now to obtain an overall better idea of precisely whether the product worked for my circumstances or not. The bathroom has quite exposed outer walls and is north facing and this, together with the fact the radiator is neither use nor ornament ensures one does not linger - it is extremely cold. Black mould caused through the condensation has been the bane of my life for many years - until now that is.  The room is still bitterly cold and the walls constantly run with condensation but there has been virtually no mould forms. What little has started to form has been pale grey, which I have immediately wiped away with a cloth - and it is gone! So far, I have only had to wipe it twice in 2 years. I can only hope it now continues with the good work.
    I am really more than pleased that I purchased the product. Many thanks for a truly valuable product."

    By Mrs Baker Home Owner United Kingdom, Thermilate Additive

    Yes I bought the powder additive which I mixed with either dulux paint or crown pain which was to make the bedroom warmer and also to help us with cols pots in corners of the walls which was getting mould which have helped 80%, Its been used to paint our daughters bedroom as in her room it has thin wallpaper so we added this to it to bring the room up to temperature which worked fine. Regards

    "Thank you for your wonderful product 'Thermilate'. It has certainly improved the insulation in our room!   Our house is 1920's and as such has little insulation and the north facing rooms especially suffered from condensation on the cold walls. After applying your product the room now feels much warmer and we have little or no condensation. I have no hesitation in recommending your product. Thank you!!"

    By Mrs Mooney Home Owner Selby, Thermilate Additive

    So far so good, does seem a bit warmer. It was very easy to use and worked wonders at covering up small cracks. Yes I do need some more please, which I guess sums up what I think. Regards,

    By Alan Huddleston Home Owner, Thermilate Additive

    Like most insulating type products, better in some areas than others. I mixed it with masonry paint and painted a section of the outside of my house and it appears to be quite effective. Because of the granular nature of thermalite you have to be careful if you want a paint finish wall, for which I would recommend further coats of un-thermalite paint on top. A recommended use would be under lining paper before wallpapering externals walls; this appears to be very effective measure against cold walls, especially older solid type walls. Hope that helpful as feedback Best Regards

    "I applied Thermilate in my bedroom. Previously the room always had a chill, but now that I have applied this revolutionary product, I'm stunned to find that it is now a lot warmer. I'm very pleased that it has done the job. I found the instructions and applying Thermilate very easy and I will be using Thermilate again."

    By Mrs Butterworth Home Owner Northumberland, Thermilate Additive

    We purchased your thermilate paint additive because we have a spare bedroom that our granddaughter uses at weekends and even with central heating we have always found the room to be cold as it has two 'outside' walls.  We used your product on the two walls when we decorated and then papered over one of the  walls.  We have found that the wall that was papered over is warm to the touch but the wall we just painted is not as successful.  I have mentioned to my husband that if we have enough paper we are going to do the wall again.  We think your product is very good.  Our house was built in 1918 and we have now found a couple of damp patches downstairs in the dining room and we will be treating these areas this winter when we decorate. Yours sincerely

    By Mrs J Bottomley Home Owner, Thermilate Additive

    Thermilate was extremely easy to use, the instructions were very clear, I simply poured it into the paint and stirred. It seemed to have cured the problem, and it actually had a fantastic added benefit for me. I decided to measure the temperature difference in the room, and to my amazement, I found that previously the average temperature in the room was 15c and now it is actually 18c, this was throughout the winter season.
    At the moment I'm just finding time to redecorate, so I can use it in the other rooms in the house too, and make the most of the heat savings. Thermilate helped save 3 degrees;  it truly is a fantastic product."

    By Mr Watson-Thomas Kent, Thermilate Additive

    "I have no central heating in my house, so in the winter, as soon as I left the lounge the house was always absolutely freezing, as this is the only room with a gas fire or any method of heating.  The bathroom was particularly cold, and also had trouble with condensation.  I saw Thermilate, and thought I'd give it a try. I decided to buy it, because it has been developed in association with NASA, and has been tested by many other independent organisations. I thought I’d give it a try, nothing to lose. I can certainly tell you I am very very happy with the results…nearly a year later and still no condensation in the bathroom, and the best thing is my house at last actually feels unbelievably warmer throughout the winter, (I could actually leave the lounge).  I haven't measured the exact temperature, I don't need to, it’s so much warmer maybe at least 3-4 degrees, even the walls feel warmer.  Thermilate is an incredible product”

    By Miss T Fenwick Home Owner Louth, Thermilate Additive

    "I would just like to leave my comments about an amazing product that does exactly what it says it says on the packet...INSULATES! The paint additive, Thermalite, really does work. I live in an old stone cottage on top of a hill (very, very windy and stormy). Over the years my husband and I have dry-lined our cottage but there was a north facing wall in the kitchen which we never got round to doing so we decided to try Thermalite instead. The difference in the heat that is retained in my kitchen now is very noticeable. Even on a mild day the kitchen used to feel quite cool. Not any more. It just feels so cosy. We are so impressed by this product that we are ordering more! I can't recommend it enough and it certainly deserves a 5 star rating."
