Insulation fill
Thermal and sound insulation with insulation fill
As levelling fill under the screed, for level compensation during renovations or as sound and thermal insulation for your new build - bulk insulation materials are used wherever insulation boards and rolls give up. As a screed company, we provide efficient thermal insulation, effective impact sound insulation and even leveling quickly and without waste.
Insulation fill with loose or bonded scattering bodies
Insulation boards are suitable for quick installation on flat walls, ceilings and floors. Insulation fillers, on the other hand, are ideal for difficult geometries. They are a small-grain scattering material that is spread by hand or blown in by machine. The loose grains distribute themselves around any obstacles, creating an even and efficient thermal barrier. Depending on the application, we as screed layers use different grain sizes or a conglomerate of different materials.
Loose insulation fills remain loose even after installation. They are therefore often used for insulating attics or in retaining systems on walls. The scattering bodies in bonded fills, on the other hand, are coated with a binding agent, which hardens when water is added and thus creates a stable insulation structure. Epoxy resin or cement are primarily used as binders.
Popular insulation fills
The selection of pourable insulation materials is huge. There is an optimum solution for every thermal and acoustic insulation requirement, even for leveling out uneven surfaces. Let us introduce you to some of the most popular materials that are used in raw or finished form. Perlite are small, white balls of naturally occurring volcanic rock. When heated briefly above 1000 °C, raw perlite expands many times over, resulting in expanded perlite with a thermal conductivity of 0.040 to 0.070 W/(m K). Expanded glass granulate uses used glass cullet, which expands when heated with binding and expanding agents to form a popular insulating material with a thermal conductivity of 0.06 to 0.70 W/(m-K). Foam glass granules are pebble-sized, angular fragments of foam glass slabs. The material from waste glass is heated and cooled in a controlled manner to produce a low thermal conductivity of 0.07 to 0.09 W/(m K) with the trapped air. Expanded polystyrene (EPS) are lightweight foam balls made from crude oil and expanded with steam. The material known under the brand name "Styropor" is inexpensive and has a thermal conductivity of 0.035-0.040 W/(m K). With dry clay fills, wood-clay mixtures, expanded glass-clay mixtures, hemp mixtures, bituminized hemp chips, spelt husks and aerogel granulates, ecologically-minded builders can find efficient building materials for environmentally-friendly insulation.Advantages of an insulation fill
A major advantage of the insulating fill is that it can be used as a leveling fill for your screed. It creates the necessary leveling that a screed layer would otherwise have to carry out in painstaking detail work. In addition, the bulk material penetrates into hidden cavities and fits snugly around existing cables and pipes. The benefits of insulating fill are also evident during processing, as we save a lot of time without cutting to size and there is no waste due to offcuts. You protect the environment and only buy as much material as you really need. The filler also allows a variable insulation thickness, which depends solely on your intended use. We are happy to put our experience as a screed company at your disposal.Wide variety of materials
The choice of organic, inorganic and synthetic insulation materials for insulation for pouring or blowing in is huge. However, most users base their choice on three characteristic values:- the thermal conductivity
- the building material class
- the material chemistry
