Thermablok works by addressing the characteristics of thermal transmission, which is at its minimum when conducting through air or a vacuum, and increases through solid objects. The building substance won’t be able to have any air exchange and you’ll get fungal growth in the brickwork. In the present context, “relative water absorption capacity by weight” refers to the amount of water that can be fully absorbed by a defined amount of the open-porous additive, i. Does gravity defy the law of conservation of energy? A rendering has the advantage of being easily applicable, flexible with respect to surface unevenness and able to fill any gaps in order to provide a continuous thermal insulation layer.

Alternatively, it is possible to use a hydrophobic open-porous additive, i. A self-supporting, thermally insulating rendering, consisting essentially of:. Aerogel is aerogel-bbased advanced material which holds 15 entries in the “Guinness Book of Records” for its unique properties, including lowest density solid and best insulator.
Your feedback will go directly to Science X editors. The dry blend according to any one of claims 1 to 4, wherein said open- porous additive has a relative water absorption capacity by weight ranging from 1 ,1 to 2,5, preferably ibsulating 1 ,8 to 2,0. Particularly suitable examples of reinforcing fibers are natural fibers, mineral fibers and organic fibers such as e.

Your email only if you want to be contacted back. The product should come onto the market next year. We do not guarantee individual replies due to extremely high volume of correspondence. But imagine if the render was pumped through the hose of a professional rendering machine at a pressure of 7 to 8 bar.

According to a further embodiment claim 3the open-porous additive has an accessible pore volume ranging from 45 to 55 Vol. Available in plastic encased strips optional self-adhesive that attach easily to the stud, Thermablok maintains its R-value over time, under a wide range of conditions.
Thermablok was developed to meet a real need to apply aerogel technology in residential and commercial insulating material. Anyone who wishes to cut down on fossil fuels must therefore insulate their home.

Micropores let oxygen and nutrients inside biofabricated tissues Dec 20, In particular, a rational use of any insulating render unavoidably requires the applicability by means of a plastering machine. Does gravity defy the law of conservation of energy? As is generally known, aerogels are solid materials with high porosity and sur- face area, low density and other interesting mechanical and non-mechanical properties.
There are a number of substances that are suitable as additives for the present invention which can be purchased in particulate form having a requested “grading curve” or “sieve curve”, i. After mixing the dry blend with water, the slurry thus formed can be applied to a surface or shaped to a self-supporting body using an overpressure without adversely affecting the thermal insulation properties.
The condensation leads to the formation of a gel phase which is subsequently converted to an aerogel by removing the solvent. Therefore, in a regular wood or metal stud wall, the areas that continue to conduct thermally are the studs, which mechanically connect one side of a wall to the other. In order to make the render “machine-compatible”, a tremendous amount of knowledge about the contents of dry render mixtures and their interactions with aerogel was required.
Detailed description of the invention Examples: Your opinions are important to us. The following are examples of materials suitable as open-porous additives in the context of the present invention: A dry blend for producing a thermally insulating rendering, consisting essentially of:. New Aerogel-based plaster provides better insulationAugust 21 retrieved 21 April from https: Cutting insulating panels to size and shape is also a cumbersome business when lining winding staircases, round arches and supporting walls.
A method for producing an element of the self-supporting, thermally insulating rendering according to one of claims 6 to 10, the method comprising the steps of:. The aerogel globules really are extremely light, almost weightless, and can be held between thumb and forefinger. The product has come through laboratory testing, and initial trials on buildings started in July He takes a transparent plastic box off the shelf and opens the lid: Heat preservation and energy saving type lightweight, gas filled wall bricks, and preparation method.
The rendering according to claim 6 or 7, wherein said thermal conductivity does not exceed 28 mW m “1 K “1.
