What is the best material for roof insulation

Roof insulation materials are as follows:

1, aluminum foil insulation coil

This insulation material is generally used in the roof, exterior walls, etc., has a very good heat insulation, heat preservation, moisture-proof, waterproof and other effects. After testing aluminum foil heat insulation coil can reflect off more than ninety-three percent of the solar radiation, is worth choosing the heat insulation material.

2, white heat insulation board

White heat insulation board is processed by special materials, the sun's light can be well reflected out, play a good role in heat insulation.

3, polyurethane foam

It is rich in color, hard material, thickness is generally in ten millimeters to two hundred millimeters, the thermal conductivity of zero-point-two to zero-point-three-five watts meters open, not only has a good thermal insulation effect, waterproof performance is also very good, but the price is more expensive.

4, rock wool board and centrifugal stripping fiber cotton

Thickness is generally in the thirty to two hundred millimeters or so, the thermal conductivity of zero point zero three eight watt meter open, common color has yellow, can be used in the construction of roofs, warehouses, rooms, etc., the thermal insulation effect is very good.

5, micro-nano insulation board

It is a high-temperature insulation board, can be used in high-temperature environments, has a very good thermal insulation effect, the thermal conductivity is generally in the zero-point-zero-two watt meter open.
