What We Supply
Products We Make for the HVAC Industry
The Problem
What HVAC Customers Face
Condensation & thermal loss
Uninsulated ducts sweat and lose efficiency. Insulation must be closed-cell, moisture-resistant and dimensionally stable at operating temperatures.
Equipment noise
Compressors, blowers and air handlers radiate noise. Acoustic treatment must fit tight spaces and survive vibration.
Air leakage at joints
Duct joints and access panels leak conditioned air. Seals need compression recovery and temperature resistance.
Long service life in harsh conditions
Roof and outdoor units face UV, ozone and thermal cycling. Materials must not degrade or outgas over years of service.
The Solution
How Parul Plast Solves Them
XLPE insulation sheets & rolls
Closed-cell cross-linked polyethylene with low thermal conductivity (0.032–0.040 W/m·K) and a -40°C to +100°C service range, available with aluminum coating.
Acoustic foam liners
Flexible PU foam cut and die-cut to line duct interiors, equipment housings and enclosures for absorption.
EPDM seals & gaskets
Weather-resistant EPDM gaskets, washers and flaps that seal panels and joints against air and moisture.
Die-cut vibration pads
Precision-cut foam and rubber pads that decouple equipment from structure and control transmitted vibration.
