Benefits

    • British Board of Agrément approved for use in all exposure zones
    • Excellent thermal and fire performance
    • Water repellent
    • Slabs ‘knit’ together, thus eliminating air gaps between adjacent slabs



Application

DriTherm Cavity Slabs are for the thermal insulation of masonry cavity external walls and are installed to fully fill the cavity. They are approved for use in buildings up to 12m high in any exposure zone and for use in multi-storey applications up to 25m in height

Environmental

DriTherm Cavity Slabs represent no known threat to the environment and have zero Ozone Depletion Potential and zero Global Warming Potential.

Knauf Insulation mineral wool products with ECOSE Technology benefit from a revolutionary, bio-based, formaldehyde-free binder technology, based on rapidly renewable materials, instead of petro-based chemicals. It reduces embodied energy and delivers superior environmental sustainability.

The technology has been developed for Knauf Insulation’s glass and rock mineral wool products, enhancing their environmental credentials without affecting the thermal, acoustic or fire performance. Insulation products made with ECOSE Technology contain no dye or artificial colours – the colour is completely natural.

Great product with unexpected results and skincare benefits
Size: 25 Count (Pack of 1)
I have been reading about Micellar water products for a couple of years, and finally purchased these wipes to try. I am currently working very long hours and the selling point for these wipes was that they weren't soap-based, and didn't require a toner after using. I keep them on my night stand and take my makeup off with them prior to going to bed. (I do not use them for removing mascara - I use another product for that.) The biggest point I want to share is that I have been using these wipes exclusively for makeup removal for a little more than two weeks. I have had a stubborn blackhead on my nose for a good 20 years that wouldn't budge, no matter how often I used exfoliating products, and I've invested a lot of money in high end exfoliators in an attempt to make that spot go away. It has grown larger over the years, and was a skincare peeve of mine. I noticed a couple of days ago that that blackhead is beginning to break down and get smaller. I thought at first that I was imagining it, but that blackhead is honestly a good two-thirds gone. This is just from using these wipes! I would never have predicted that something this simple and quite soft and insubstantial as a disposable face wipe would have such effective results for blackhead breakdown, but they're doing the trick. I have noticed smaller blackheads on my chin area are also melting away. I predict that in another few weeks of use, my skin is going to be as close to blackhead-free as it is humanly possible to achieve. (For the record, I don't have a lot of blackheads - just a handful that have taken up residence over the years and refused to budge, getting larger with age.) These are safe for my sensitive skin, and have exfoliating benefits that I wouldn't ever have expected or predicted. Full disclosure: I do spend a good 3-5 minutes using a single wipe on my face, neck, and décolletage, scrubbing with the nubby side (there is a nubby, exfoliating side, and smooth side to each wipe) and using the whole cloth in sections until I have used it all. Finally, I also use it on the tops of my hands. I definitely get my money's worth out of each wipe! I wholeheartedly encourage people to try this product. I now have it on Auto-Ship status, as I don't want to ever be without these wipes in my skincare arsenal.

Cool and moist
Size: 1 Count (Pack of 2)
I had to get away from scented products and this one was cleared by my ACDS app. It is small, not resealable, but easy to use, and cleans well, the wipes are sturdy, and just wet enough to clean without needing extra drying. These are travel size and have to be kept in a zip lock after opening.

Good choice for sensitive skin
Size: 25 Count (Pack of 1)
I purchased this in preparation for a trip. I wanted to be able to clean my face while on a flight but have super sensitive skin so normal makeup wipes burn and cause a lot of irritation. These are very similar to baby wipes. They have virtually no scent and work relatively well in getting off sunscreen. I haven tried with makeup yet so I can’t speak on that. I used about 2 or 3 and my face didn’t burn at all. I think it’s a good choice for those who want the convenience of a makeup wipe but can’t use regular ones.
