About this deal
To accommodate for local requirements and regulations, specific product information is available on our local product pages. During the construction process, a damp proof membrane will be laid over a layer of sand, before insulation is placed on top, and finally the concrete is poured. Our flat roof range maintains its high performance against cold and moisture, while the versatile installation methods of our pitched roof products means you can protect your project with above, in between and below rafter insulation or with easy-to-fit loft floor solutions, to achieve the best results.

Arc-shaped grooves with a height of 50 µm, 100 µm and 120 µm are obtained with a flat milling cutter with a tip diameter of 300 µm that provides grooves with a depth of 340 µm, 290 µm and 270 µm, respectively, as shown in Steps 1–3. If you have bats within your roof you will probably not be allowed to install insulation as their nesting areas are protected.Easily added with insulation below or above the rafters to increase thermal, acoustic and fire performance. Any small amount of vapour that does exist within the wall cavity will evaporate outside due to the porous nature of bricks. Its values remain above the regime of quick disappearance, except for AAO+nanoparticles where the regime of interest is achieved between 500 °C and 570 °C.

The Leidenfrost point can be elevated by texturing materials to favour the solid–liquid contact 2, 3, 4, 5, 6, 7, 8, 9, 10 and by arranging channels at the surface to decouple the wetting phenomena from the vapour dynamics 3.
By installing insulation sourced from innovative stone wool, our products can help reduce the amount of energy that needs to be used to heat buildings – and save money on energy bills too.
