Введение продукции

Phenolic pre-insulated ductwork is fabricated from rigid closed-cell phenolic foam panels laminated with aluminum foil on both faces. The relatively low thermal conductivity provides useful insulation in a thin wall, leaving more service space around the finished duct. Sections are produced by grooving, folding and sealing the panel, then connected using aluminum or polymer profiles with foil tape and vapor-compatible sealant. The system is intended for dry HVAC air distribution and benefits projects that need low installed mass and a clean external finish.

Основные характеристики

Closed-cell phenolic foam limits heat transfer and moisture migration through a compact panel thickness.

Aluminum foil laminates protect both panel faces and form the visible air and vapor barriers.

Low panel mass simplifies lifting through congested plant rooms and above cleanroom ceilings.

Purpose-made connection profiles protect foam edges and transfer loads across section joints.

Обеспокоенность клиентов продуктами

Phenolic duct performance depends on preserving the foil skins and sealing every groove, corner and transverse connection without crushing the foam core.

Limited ceiling depth leaves little room for bulky external duct insulation.A thin phenolic wall integrates insulation directly into the duct envelope.

Unprotected foam edges release particles during handling.Edge channels, foil tape and sealant enclose every cut face before installation.

Vapor leakage at panel corners produces hidden condensation.Continuous external foil tape bridges the corner and connects the facing into one vapor barrier.

Point loads from hangers crush the lightweight panel.Wide support saddles distribute the duct weight across reinforced outer surfaces.
