The Best of The Best. Our 10mm Twin Wall Polycarbonate Sheeting features two parallel outer skins connected by a series of vertical internal webs, forming enclosed air channels that provide a significant thermal break. Manufactured to ISO 7823-2 and EN 4892-2 standards, it combines high light transmission with the structural strength needed for demanding commercial and agricultural applications.
Our 10mm Twin Wall Polycarbonate Sheeting features two parallel outer skins connected by a series of vertical internal webs, forming enclosed air channels that provide a significant thermal break. Manufactured to ISO 7823-2 and EN 4892-2 standards, it combines high light transmission with the structural strength needed for demanding commercial and agricultural applications. A co-extruded UV-stabilised layer on both outer surfaces ensures long-term colour stability and resistance to yellowing.
Thermal Insulation
U-value of ~2.1 W/m²K — the twin wall construction significantly reduces heat loss.
UV Stabilised
Co-extruded UV-protective layer on both faces prevents yellowing and degradation.
Lightweight
At ~2.0 kg/m² it is a fraction of the weight of glass, reducing structural loads.
High Impact Resistance
Virtually unbreakable compared to glass — ideal for hail-prone or high-traffic areas.
Light Diffusion
Scatters direct sunlight evenly, reducing hot spots and glare beneath the sheet.
Flexible Installation
Cold-bendable from 1500mm radius — suits curved and barrel-vault roof designs.
Acoustic Performance
Sound reduction of ~20 dB Rw for quieter indoor environments under the sheet.
Fire Rated
Classified to EN 13501-1 Class B — meeting building regulation requirements.
Applications
10mm twin wall sheeting is a versatile glazing material used across a broad range of commercial, agricultural, and domestic projects.
