Single Layer Trapezoidal Sheets

Single Layer Trapezoidal Sheets

  Single layer trapezoidal sheets are used on roofs and facades that do not need thermal insulation or where on-site sandwich application is employed by using rock wool, glass wool, high-density polyurethane, or polystyrene foams as filling material between two metals.
 
 Another area where single-layer trapezoidal sheets are used is terrace roofs. In such applications, membrane waterproofing is made on the upper part of the roof. The above-mentioned rigid heat insulation materials are used underneath the membrane and there are single-layer trapezoidal sheets at the very bottom.
