| |
| − | | |
| − | The roofing assembly / material information published in the <b>RCABC <i>Roofing Practices Manual</i></b> does NOT represent a complete set of the manufacturer’s data or specifications. The preparation of a detailed specification is the responsibility of the design authority.

| − | Retro-Fit Board is a perlite-based utility board for use as a divorcing layer in reroofing and in new construction as a top layer in a multi-layer insulation system.
| |
| − | | |
| − | Half-inch Retro-Fit Board is a high density board made of expanded perlite and cellulosic fibres. It serves as an upgrade for wood fibre utility roofing products. The perlite particles are subjected to intense heat, which causes them to expand approximately fifteen times their original size.
| |
| − | | |
| − | The top surface is sealed with Top-Loc coating to ensure good attachment in bituminous applications. The minimum recycled content is 35% by weight.
