Polycarbonate 8mm triple wall r value is 2 0. U values are largely unaffected by the color of plexiglas sheet. Polycarbonate 16mm triple wall r value is 2 5. Acrylic single glazed clear 0 92 0 89 0 77 1 19 1 10 0 90.

As we said before the r value measures the thermal resistance of a material. Acrylic sheets also referred to as plexiglass or plexiglas are often used as an alternative to glass sheeting. The higher the r value the greater the insulation performance. Should acrylic scratch it is relatively easy to polish to get rid of the scratches.

Acrylic is also impact resistant and especially useful where breakage can be an issue. Additionally acrylic sheeting comes in a variety of styles including colored acrylic sheet fluorescent acrylic sheet and black and white acrylic sheet.

Plexiglass sheets offer similar transparency to glass but they are more durable and relatively shatter proof.

The values tabulated below are u factors for vertical windows and horizontal skylights plexiglas glazing. Acrylic can withstand temperatures ranging from 30 to 160 degrees f. Polycarbonate 8mm twin wall r value is 1 69. Acrylic twinwall r value is 1 82.

Notes to the table above. The amount of heat conducted through plexiglas glazing is slightly lower than for glass of the same thickness. Polycarbonate 16mm five wall r value is 3 2. Notes on the r value k values of different forms of asbestos.

Polycarbonate 6mm twin wall r value is 1 54. Rosato asbestos insulation is the most authoritative source on asbestos properties and gives data for the thermal conductivity of asbestos in different forms and with varying temperatures for magnesia asbestos insulation at mean temperatures ranging from 100 f to 400 f the k value thermal. The following is a chart showing the r value of various materials for greenhouse use. Acrylic sheeting can be used to replace window panes protect surfaces or even hold items as shelving.
