A typical 6mm sheet has a density of 0.72 g/cm^2 [6] and a thermal insulation R value of 0.3 m^2°C/W, while allowing 80% of visible light pass through. [7] These attributes, coupled with a service temperature range in excess of 120 °C (-51 °C to 71 °C), makes polycarbonate the ideal material for twinwall application.
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.
Thermally processed material is usually totally amorphous, [7] and as a result is highly transparent to visible light, with better light transmission than many kinds of glass. Polycarbonate has a glass transition temperature of about 147 °C (297 °F), [8] so it softens gradually above this point and flows above about 155 °C (311 °F). [9]
Similarly, many plant-based waste materials can be used as insulation such as nut shells, corncobs, most straws including lavender straw, recycled wine bottle corks (granulated), etc. They usually have significantly less thermal performance than industrial products; this can be compensated by increasing thickness of the insulation layer. [17]
Polyethylene plastic sheet, 4 or 6 thou (0.10 or 0.15 mm), 0.03 US perm (1.7 SI perm). Advanced Polyethylene vapor retarders that pass the ASTM E 1745 standard tests ≤0.3 US perm (17 SI perm). Asphalt-coated kraft paper , often attached to one side of fiberglass batts, 0.40 US perm (22 SI perm).
External wall insulation systems generally comprise firstly an insulation layer (an element which helps to achieve the requisite thermal performance); and secondly,a protected weatherproof finish (usually a render, although brick slips, [3] tiles, and decorative boards can also be used). Insulating render can also be an advantage in certain ...
