Seaweed under the roof - Research News March 2013 - Topic 2. Throughout fall, winter and spring, Mediterranean beaches are littered with little balls of seaweed leaves from the Posidonia oceanica plant, more commonly known as Neptune grass.

Seaweed under the roof - Research News March 2013 - Topic 2

Although the natural material of these Neptune balls is regarded as a waste product and generally ends up as landfill, this readily abundant and renewable material is far too valuable to be thrown away. It displays a variety of characteristics that make it of interest to the building trade: seaweeds are virtually non-flammable, resistant to mold, and can be used as insulating material without the need for chemical additives. It can be used as insulation between the rafters of pitched roofs, to insulate interior walls, or to reduce the amount of heat lost through building envelopes. Fibers act as a buffer, absorbing water vapor and releasing it again without impairing its own ability to keep the building insulated. Denim Insulation in Layman's Terms. Last updated on June 28, 2020 Denim insulation is the new popular type of environmentally-friendly material.

Denim Insulation in Layman's Terms

Let’s see what it’s all about and compare it to other popular materials in layman’s terms. The idea of recycling old denim that otherwise fills up landfills is a neat idea that helps the environment too. Linisolering som är bra för både hus och miljö - Ekologiska Byggvaruhuset. Linisoleringens speciella egenskaper Linisolering har flera speciella egenskaper som skiljer det från många moderna syntetiska isoleringsmaterial.

Linet är likvärdigt som värmeisolering men kan genom sin förmåga att uppta och avge vattenånga i sina fibrer även isolera bra trots att det innehåller en viss mängd fukt. » Isolering. Text och foto: Cathrine Bülow.

Miljöanpassade isoleringsmaterial skall ha god värmeisolerande förmåga. De ska inte innehålla skadliga fibrer, kemikalier eller ha ett petrokemiskt ursprung. Använd de byggekologiska isoleringsmaterial som finns på marknaden, av till exempel hampa och cellulosa. Olästa tidningar isolerar byggnader - Miljönytta. Inside Insulation. How the Transport of Moisture in the Walls of Timbered Houses Works During the Heating Season.The transport of moisture through building components works by means of vapour transport (diffusion and convection) or by liquid movement (capillarity).Water vapour diffusion is the process of pressure compensation, where air with a higher vapour pressure (warm, humid air) tries to move in direction of air with a lower vapour pressure (cold, dry air).

Inside Insulation

In a building, due to the vapour pressure gradient, the warm and humid internal air diffuses through building components (e.g. the exterior walls or the roof). The diffusion process takes place at all times. When diffusing, the air cools down inside of the different building components. In the worst case this can lead to condensation inside of the building components. The amount of condensate calculated according to DIN 4108 does sometimes exceed the limit allowed.

Insulation - Lowimpact.orgLow impact living info, training, products & services

It is any material that slows down the rate at which heat is lost through the fabric of your building (although it can also mean sound or fire insulation, or keeping heat out, this factsheet is about keeping heat in). Air is actually the insulator, and the material is a way of trapping air. For example, you may sleep under a duvet containing eider (duck) feathers. The feathers trap air, which retains your body heat and keeps you warm (the feathers do exactly the same job on the duck too). Insulation can be in your loft; on interior walls, exterior walls or in the cavity between walls; under floors; or around pipes and hot water cylinders. Installing internal wall insulation. Houses had solid walls until the 1920s, when they started to be built with two walls with a cavity in between. K-values, R-values and U-values The insulation properties of a material can be expressed by its k-value.

The Best Insulation Types for Your Home

About 65 percent of U.S. houses are poorly insulated, a 2005 Harvard study estimates. Fortunately, you can cut heating and cooling bills by about 30 percent with proper insulation. Top 5 Green Insulation Options. Is there anything soybeans can't do? You can find them in milk, candy, disinfectants, insecticides, cooking oils, margarine and now, home insulation. Chicago homeowners Jason and Jennifer LaFleur learned all about insulation when they began renovating their kitchen. They found that they didn't need to buy conventional fiberglass insulation. Instead, they sprayed soybean foam insulation into their walls [source: Pandolfi]. The LaFleurs discovered what other homeowners are now learning -- that the color of home insulation isn't just pink.
