Heavy stone slabs (not to be confused with slate) 1–2 inches thick were formerly used as roofing tiles in some regions in England, the Alps, and Scandinavia. Stone slabs require a very heavyweight roof structure, but their weight makes them stormproof. An obsolete roofing material, now used commercially only for building restoration.
This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value.
Examples of renovation are post-insulation of a cavity wall and post-insulation of a sloping roof against the roof boarding or under the tiles. Note that every renovation must meet the minimum Rc value of 1.3 W/(m 2 ⋅K). If the current insulation has a higher insulation value (the legally obtained level), then this value counts as a lower ...
It can be used as internal insulation : between studs, joists or ceiling rafters, under timber floors to reduce sound transmittance, against masonry walls or externally : using a rain screen cladding or roofing, or directly plastered/rendered, [24] over timber rafters or studs or masonry structures as external insulation to reduce thermal ...
While in 1976 there were roughly 100 cellulose insulation firms with 125 plants in the US, by 1978 there were more than 350 firms with more than 500 plants 1. Cellulose insulation was produced locally by small manufacturers who purchased ready-to-operate machines and offered a cheap and easy low-tech production process.
Amakan are used as walls in the traditional nipa huts (bahay kubo) of the Philippines. They are lightweight and porous, allowing air circulation to keep buildings cool in the hot tropical climate. The porosity also balances pressure inside the house during strong winds, minimizing roof damage. [4] Amakan needs to be treated before installation.
Building energy consumption can be cut by 20% under a combination of insulation, efficient windows and appliances, shading, reflective roofing, and a host of automated controls that adjust energy use.
[2] The company was renamed SIG plc in 1995. [3] Norman Adsetts retired the following year. [3] Acquisitions in the end of the 1990s included WKT and Golinski of Germany in 1996, and Asphaltic, a major roofing supplier in the United Kingdom, CP Supplies and Branton Industries and Distribution International in the United States in 1997.
