  3. Wool insulation - Wikipedia

    en.wikipedia.org/wiki/Wool_insulation

    Wool insulation commonly comes in rolls of batts or ropes with varied widths and thicknesses depending on the manufacturer. Generally, wool batts have thicknesses of 50 mm (2 in) to 100mm (4 in), with widths of 400 mm (16 in) and 600 mm (24 in), and lengths of 4000 mm (13 ft 4 in), 5000 mm (16 ft 8 in), 6000 mm (20 ft) and 7200 mm (24 ft).

    It is made from the waste wool that the carpet and textile industries reject, and is available in both rolls and batts for both thermal and acoustic insulation of housing and commercial buildings. Wool is capable of absorbing as much as 40% of its own weight in condensation while remaining dry to the touch.

  5. Mineral wool - Wikipedia

    Their drawbacks when compared to mineral wool are their substantially lower mold resistance, higher combustibility, and slightly higher thermal conductivity (hemp insulation: 0.040 Wm-1 k-1, mineral wool insulation: 0.030-0.045 Wm-1 k-1). [16]

  6. Glass wool - Wikipedia

    en.wikipedia.org/wiki/Glass_wool

    Glass wool batt insulation. Glass wool is an insulating material made from glass fiber arranged using a binder into a texture similar to wool. The process traps many small pockets of air between the glass, and these small air pockets result in high thermal insulation properties. Glass wool is produced in rolls or in slabs, with different ...

  7. R-value (insulation) - Wikipedia

    en.wikipedia.org/wiki/R-value_(insulation)

    Loose cellulose, fibreglass (both blown and in batts), and rock wool (both blown and in batts) all possess an R-value of roughly R-2.5 to R-4 per inch. Straw bales perform at about R-2.38 to 2.68 per inch, depending on orientation of the bales. [42] However, typical straw bale houses have very thick walls and thus are well insulated. Snow is ...

  8. Wood wool - Wikipedia

    en.wikipedia.org/wiki/Wood_wool

    Excelsior, or wood wool. Wood wool, known primarily as excelsior in North America, is a product made of wood slivers cut from logs. It is mainly used in packaging, for cooling pads in home evaporative cooling systems known as swamp coolers, for erosion control mats, and as a raw material for the production of other products such as bonded wood wool boards.

  9. Insulated glazing - Wikipedia

    en.wikipedia.org/wiki/Insulated_glazing

    Greater space increases the insulation value up to a point, but eventually with a large enough gap, convection currents begin to flow carrying heat between the panes within the unit. Typically, most sealed units achieve maximum insulating values using a space of 16–19 mm (0.63–0.75 in) when measured at the centre of the IGU.
