Green Technology: Use High-tech Aerogels for Building Insulation

Tradematt Aerogels, a company that makes industrial insulation, has begun selling air-cushion pads that make existing buildings more energy-efficient. Aerogels companies have already installed this material in the United Kingdom and parts of the United States, including last year's construction project in Rhode Island, USA.
Aerogels is made from a gel that draws liquid material, of which over 90% is air. The Aerogels has a nanoporous structure that makes it difficult for heat to penetrate through it. As a result, Aerogels is a good lightweight insulation.
For cost reasons, Aerogels manufacturers used to focus primarily on high-end industrial applications such as heat-insulated oil and gas pipelines and even Mars spacecraft.
However, many Aerogels companies are now starting to offer ultra-thin Aerogelscushions that can replace traditional fiberglass, foam and fiber insulation. The up-front cost of the aerogels is still high, but the cost of this material has been reduced to a point affordable for civil use, making it particularly suitable for the construction of masonry or arched walls.
We opened our first manufacturing facility in 2008, so we have the ability and cost advantages to enter the traditional building insulation market.
Tradematt Aerogels insulation pads offer 2 to 4 times more insulation per inch than glass or foam insulation. The compatibility of this material is also very good, water vapor can easily pass, in addition, this air-cushion pad fire performance is not bad, that put a gas lamp in the bottom, this mat will not burn.
- The application is not yet widespread
Does this mean that you should consider using Aerogels pads on your walls, floors or attic? Not necessary. The upfront cost of Aerogels insulation is still high, so it's best for walls that do not have fenestrated openings in wooden frames.
The Rhode Island Housing Agency used a tradematt Aerogels cushion to refurbish a brick building without insulation built in the 1940s. The building has five floors and a total of 50 units. The construction contractor nails the Aerogels pad inside the wall, fixes it to the building board with screws, and then a layer of gypsum and paint. The benefits of doing so is that it will not damage the original structure of the house too much and will increase the interior space less than 1 inch.
In addition, contractors have applied aerogels to super-insulated houses, which completely prevent external heat influx. For those wooden frame houses, thin strips of Aerogels material (thermal bridging) can also be used.
In the next few years, the cost of Aerogels projects will gradually decline, however, the decline will not be dramatic. However, with the tightening of housing construction regulations, Aerogels materials can be applied to more applications. Housing refurbishment is just the initial application of Aerogels, and we will use that material in more buildings as we go deeper.
