Polycarbonate Roofing Sheets

Light-transmitting sheets for skylights and roofing applications.

Where metal roofing delivers strength and weather resistance, polycarbonate roofing sheets deliver something metal cannot – natural light. Polycarbonate Roofing Sheets from Astal Roofing Industries offer a range of high-performance glazing and wall panel solutions that bring daylight into industrial spaces, meet the stringent hygiene requirements of clinical environments, and provide thermal insulation in multi-layered architectural applications. Our Lexan polycarbonate sheet range covers three specialist product variants – each engineered for a distinct set of performance requirements and application types across industrial, commercial, and institutional projects in India.

What Are Polycarbonate Roofing Sheets?

Polycarbonate is a high-performance thermoplastic material that combines near-glass optical clarity with an impact resistance up to 250 times greater than glass and a weight approximately 50% lower – making it the material of choice for roofing, glazing, and wall panel applications where transparency, safety, and durability must coexist. Unlike glass, polycarbonate does not shatter on impact – it absorbs and distributes impact energy through the panel without fracture, making it inherently safer in environments where overhead glazing failure would create a safety risk.

Our Lexan polycarbonate sheet range is available in three distinct product variants – solid sheet, clinical wall panel, and multiwall sheet – each optimised for a specific combination of optical, mechanical, hygiene, and thermal performance requirements.

Our Lexan Polycarbonate Sheet Range

1. Lexan Polycarbonate Sheet - Solid Sheet for Roofing & Glazing

Lexan Polycarbonate Sheet is a solid, single-layer polycarbonate panel offering glass-like optical clarity combined with exceptional impact resistance and a lightweight profile that makes it practical for large-format roofing and glazing installations. The UV-stabilised surface coating protects against yellowing and surface degradation from prolonged solar exposure – maintaining optical clarity and structural integrity across years of outdoor service in India’s high UV climate.

Glass-Like Clarity

Up to 90% light transmission – delivering natural daylight into industrial buildings, warehouses, and commercial spaces without the weight, fragility, or cost of structural glazing systems.

High Impact Resistance

Up to 250x the impact resistance of glass – resistant to hail, wind-borne debris, and accidental impact without cracking or shattering, making it the safe specification for overhead roofing and safety barrier applications.

Lightweight

Approximately 50% lighter than equivalent glass panels – reducing structural load, simplifying installation, and enabling larger panel formats without heavy lifting equipment.

Applications

Skylights and rooflights in industrial buildings and warehouses, greenhouse glazing, safety barriers and machine guards, canopy and shelter roofing, and natural light panels integrated into metal roofing systems.

2. Lexan Clinical Wall Sheet - Hygiene-Grade Wall Panels for Clinical Environments

Lexan Clinical Wall Sheet is a specialist polycarbonate panel engineered for environments where surface hygiene, chemical resistance, and ease of cleaning are regulatory requirements rather than optional features. The panel surface is formulated to resist the cleaning chemicals, disinfectants, and sterilising agents used in hospital, laboratory, food processing, and pharmaceutical environments – maintaining its surface integrity and hygiene performance through repeated cleaning cycles without degradation, staining, or bacterial harbouring in surface imperfections.

Chemical & Stain Resistance

Resistant to a broad spectrum of hospital-grade disinfectants, cleaning chemicals, and food processing sanitisers – maintaining surface integrity and appearance through the rigorous cleaning regimes required in clinical and food safety environments.

Easy to Clean

The smooth, non-porous surface does not harbour bacteria, fungi, or contaminants between cleaning cycles – meeting the hygiene standards required for hospital wards, operating theatres, laboratory spaces, and food contact environments.

Impact Resistant & Durable

Approximately 50% lighter than equivalent glass panels – reducing structural load, simplifying installation, and enabling larger panel formats without heavy lifting equipment.

Applications

Hospital corridors, wards, and operating theatres, pathology laboratories and research facilities, food processing plants and commercial kitchens, pharmaceutical manufacturing clean rooms, and veterinary and dental facilities.

3. Lexan Multiwall Sheet - Multi-Layered Polycarbonate for Thermal & Acoustic Performance

Lexan Multiwall Sheet is a multi-layered polycarbonate panel with internal longitudinal chambers that provide thermal insulation, acoustic attenuation, and structural rigidity significantly superior to solid single-layer polycarbonate of equivalent thickness. The cellular internal structure traps air between layers – creating a lightweight thermal barrier that reduces heat gain and loss through the panel while maintaining the light-transmitting properties that make polycarbonate the preferred glazing material for greenhouses, atriums, and canopy structures.

Multi-Layered Thermal Performance

The internal chamber structure provides a measurably higher thermal resistance than solid sheet – reducing solar heat gain in summer and heat loss in winter, which is particularly valuable in greenhouse, atrium, and covered walkway applications where thermal comfort and energy efficiency are design priorities.

Acoustic Attenuation

The cellular wall structure absorbs and attenuates sound transmission – making multiwall polycarbonate an effective acoustic barrier for noise-reduction partitions, covered outdoor areas adjacent to traffic or industrial noise sources, and internal partitioning in open-plan industrial and commercial buildings.

Lightweight Structural Rigidity

The multi-wall geometry provides panel stiffness significantly greater than solid sheet of the same weight – enabling longer spans between support members and larger panel formats in canopy, atrium, and greenhouse roof structures without additional framing.

Applications

Greenhouse and horticulture facility roofing, atrium and skylight glazing in commercial buildings, covered walkways and canopy structures, noise-reduction partitions and acoustic barriers, and sports hall and swimming pool roofing where thermal and acoustic performance both matter.

Key Features Across the Lexan Range

UV-Stabilised Surface

All Lexan sheet variants carry a UV-stabilised outer surface coating that prevents yellowing, surface embrittlement, and optical degradation from prolonged solar exposure – maintaining performance and appearance across the full service life of the installation in India’s high UV climate zones.

High Impact Resistance

Polycarbonate’s inherent toughness makes every Lexan sheet variant significantly safer than glass in overhead and vertical glazing applications – resistant to hail, accidental impact, and wind-borne debris without shattering or producing dangerous fragments.

Lightweight & Easy to Handle

Approximately 50% lighter than equivalent glass panels across all variants – reducing structural load requirements, simplifying on-site handling and installation, and enabling larger panel formats without heavy lifting equipment.

Excellent Light Transmission

High optical clarity across solid and multiwall variants delivers natural daylight into buildings – reducing artificial lighting loads and improving the quality of the internal environment in industrial, commercial, and agricultural applications.

Weather & Temperature Resistant

Performs across India’s full climate range – from sub-zero winter temperatures to peak summer heat exceeding 50°C ambient – without warping, cracking, or losing optical or mechanical performance across extended outdoor service.

Available in Custom Sizes & Tints

Supplied in project-specific panel dimensions, thicknesses, and tint options – clear, opal, bronze, and green tints available across variants to control light transmission, solar gain, and visual privacy to the specification required by each project.
