Where the cover must be rigid — walls, roofs, end-walls — polycarbonate glazes the greenhouse. Multiwall (hollow) sheet adds insulation and impact strength; a co-extruded UV layer protects the panel against yellowing. We supply multiwall and solid polycarbonate in standard thicknesses and structures. Tell us thickness, structure and dimensions — we quote by sheet or m².
