Insulation is a substance that is used to decrease heat loss or gain. Insulation suppliers and installers are the companies that sell and install various forms of insulation for construction projects. It's available in various materials and forms, including glass fibre, polystyrene, polyester, wool, paper, blankets, rigid sheets, segments, and loose-fill. Only the best insulation companies in New Zealand are featured at ArchiPro.
The thermal resistance or R-value of insulating material is measured or graded in terms of its resistance to conduct heat flow. The higher the R-value, the better the insulating efficacy. The R-value is determined by its material, thickness, and density.
