Plastica have developed a unique solution for underground ductwork. Historically such application may have used a metallic ductwork system. Such systems prove to be subject to corrosion, both internally and externally, and mechanical failure due to ground, and other external factors.
Plastica system is an all Plastic Construction, utilising a unique bracing system designed to enhance the mechanical structure whilst only offering a very low pressure drop, normally a K factor of 0.2 can be used.
The system has an excellent thermal insulation property, with a thermal conductivity of 0.22 W/M2
A complete range of Ductwork items, bends, taper, spigots, dampers etc can be supplied.
The material has excellent Ball impact strength and shore hardness characteristics. Ductwork is available in various materials including uPVC, uPVC/GRP, PP and PP/GRP.
Sizes range from 125 Dia to 3000 Dia and also available in rectangular up to 3000 by 3000. Construction specifications include DW154, SMACNA and other international standards
