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

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.

Love this bag, wish it was even bigger!
Color: Sorrel
This is a nice squishy pebbled leather crossbody tote. I'm using it as a work bag BUT it won't fit a 16 inch laptop so if that's a consideration skip this one. It does fit a 10 inch iPad and Kindle, plus a compact umbrella, wallet, over ear headphones, full size body spray and lotion, big pack of gum, several lip products and dental floss, mini hand sanitizer, small brush, pens and a notebook... So basically my whole life fits in it aside from my laptop. It smells like leather, and I love that. The brown color has lots of variations so it looks like it has a patina already. I sprayed it with Apple Garde for waterproofing and it didn't affect the feel or color of the bag at all. This bag is really pretty and I get compliments on it daily. The zipper seems sturdy and never catches or gets stuck. It molds itself to my body like a softer leather should and I would say that it's absolutely worth the price. The strap is wide, sturdy, and comfortable too. There are multiple pockets on one inner side, a zippered middle compartment, and a zippered side compartment on the inside as well, along with an outer pocket so there's plenty of organization without having to buy an insert. I wish they had this available in an even bigger size to fit a standard laptop!

Expectations not met re. bag!
Color: Navy Blue
The seller was fantastic, as he/she accepted my return and refunded me immediately. Seller gets 5 stars. Even thou this bag is a stunning Navy Blue, BEAUTIFUL stitching, beautiful zippers and liner, wrapped professionally with TLC, I could not stand the very strong smell. I don't know if the smell was due to the navy blue color/dye or not. I can't even describe the smell... besides that it's not leather. I was gifted the same bag in "light brown" and that bag smells like leather; it's like you are in Rome shopping for the real thing! I love that bag as I can wear it crossbody, shoulder or hand held. Unfortunately, it too small for me. So I thought, if I am buying bigger, let's do the dark blue. Was I wrong. I really had high expectations for this bag. :0(

Love it
Color: Sorrel
So thought I would give this purse a try. Never bought anything like this on Amazon. My much much more expensive designer brand had to be replaced. I really like this purse. It’s the perfect size and very nicely made

So cute and dressy. Fit well and bought 1/2 size smaller than usual.
I usually wear sneakers and wanted shoes that were a bit dressier for going out for dinner with my husband. I usually wear a size 7 but bought these in a size 6 1/2 as recommended. I tried them on with bulky wool blend socks that I normally wear, and they fit perfectly. Since I intend to use these boots for dress, I didn't wear them for a long period of time, but found them to be comfortable, and the heal was not too high. The top of the boot is high enough, that it would still be covered by pant legs when you sit down. I also like that the zipper opening in the side made them very easy to get on and the zipper worked very well without sticking. I also like the stacked heal vs. a higher, thinner heal. Although I used to wear 3" spike heals when I was younger, I am now 77 years old, I am more comfortable and feel safer with a thicker heal. Overall, I very much like these ankle boots, and would recommend them. I hope this review is helpful for you.

Amazing boots!
These boys are gorgeous visually, then when you put them on you can feel the cushioning inside. So comfortable! There is plenty of room in the width, I take a 7 and it for perfectly without being tight with sock on. Outside feels so soft to touch, can't believe quality for the price!
