Roofing material is the outermost layer on the roof of a building, sometimes self-supporting, but generally supported by an underlying structure. A building's roofing material provides shelter from the natural elements. The outer layer of a roof shows great variation dependent upon availability of material, and the nature of the supporting ...
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.
Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes ...

During the 2nd century C.100 -C.200 it was the first time human civilisation was introduced to material of cork, and it was only until the 19th century when cork was widely used leading to major industrial production. [20] Cork, which is harvested from the Oak trees generally found in Portugal, Spain and other Mediterranean countries.
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. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.
Some roofing manufacturers' warranties are rendered void due to standing water. 2. To protect the building interior from the effects of weather elements such as rain, wind, sun, heat and snow. 3. To provide thermal insulation. Most modern commercial/industrial roof assemblies incorporate insulation boards or batt insulation.
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.
