Basic asphalt shingles cost between $2,000 and $4,000 for the material alone, while premium options such as copper can cost more than $40,000. Roof Material Average Cost
Copper roofs have a high initial cost but very long lifetime: tests on European copper roofs from the 18th Century showed that, in theory, copper roofs can last one thousand years. [6] Another advantage of copper roofing systems is that they are relatively easy to repair. Standing-seam metal roof with concealed fasteners.
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.
A small quantity of polyolefin is melted as an adhesive to bind the product together (and is preferable to formaldehyde adhesives). Installation is similar to fiberglass, without the need for a respirator but requiring some additional time to cut the material. Cotton insulation costs about 10-20% more than fiberglass insulation.

Common insulation applications in an apartment building. According to a mineral wool manufacturer, the first mineral wool intended for high-temperature applications was invented in the United States in 1942 but was not commercially viable until approximately 1953. More forms of mineral wool became available in the 1970s and 1980s. [4]
Wood wool boards are rigid and very strong. Their thermal conductivity is higher than other insulation material between 0.070 and 0.100 W/(m.K) compared with mineral wool insulation materials to approximately 0.040 W/(m.K). But their specific thermal capacity and therefore summer heat insulation is higher than other materials, e.g. when ...

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).
