16mm Polycarbonate Sheet
When searching for roofing materials for your sunroom, industrial skylight, or high-end greenhouse project, 16mm polycarbonate sheet undoubtedly tops your list. But what exactly is it? Why is it so popular? And how do you choose and use it correctly? This article serves as your ultimate guide, providing a comprehensive analysis of this star product—from technical parameters and core applications to selection tips and installation maintenance.
What is a 16mm Polycarbonate Sheet?
A 16mm polycarbonate sheet refers to a multi-chamber, hollow-structured panel with a total thickness of 16 millimeters. It is not solid but features a twin-wall or multi-wall structure formed by vertical ribs. This design ensures exceptional strength while offering outstanding lightweight properties and thermal insulation.
Why is 16mm the "Sweet Spot"? Key Physical Properties
Compared to thinner 8mm or 10mm sheets, the 16mm version offers a significant performance leap:
Superior Thermal Insulation (Lower U-Value): The increased chamber thickness effectively blocks heat transfer, with a U-value as low as 1.3 W/(m²·K), rivaling some wall insulations and significantly reducing energy costs for climate control.
Exceptional Impact Resistance: Polycarbonate material is 250 times more impact-resistant than glass, and the 16mm thickness can withstand heavier hail and falling objects.
Excellent Structural Strength: Greater span capability allows for wider purlin spacing, potentially reducing support structure costs.
In-Depth Analysis: 16mm Polycarbonate Sheet Technical Data Sheet
| Parameter | Value / Description | Notes |
|---|---|---|
| Total Thickness | 16 mm | Core specification directly affecting insulation & strength |
| Structure | Twin-Wall / Multi-Wall | Standard hollow chamber design |
| Standard Width | 2100 mm | Common sheet width; consider for transport & installation |
| Standard Length | 5800 mm, 11800 mm, or Custom | Longer sheets reduce joints, improve integrity |
| Light Transmission | Up to 80%+ for clear sheets | 16mm clear polycarbonate sheet offers excellent daylighting |
| Weight | Approx. 1.5 – 1.7 kg/m² | Extremely lightweight, about 1/12 the weight of equivalent glass |
| Thermal Expansion Coefficient | 0.065 mm/(m·°C) | Expansion gaps are mandatory during installation |
| Impact Resistance | Extremely High | Meets safety standards, shatterproof |
| Service Temperature Range | -40°C to +120°C | Suitable for most climatic conditions |
These superior parameters make it an ideal replacement for traditional glass (heavy, fragile) and cheap PVC corrugated sheets (prone to aging, poor insulation), especially for projects with stringent requirements for temperature control, safety, and durability.
