Marvault HF and RL uses premium quality Marlon FS, solid polycarbonate sheet and Marlon ST Longlife, multi-wall polycarbonate sheet. Marlon FS is an outstanding solid polycarbonate glazing material offering optical clarity similar to that of glass. It is a relatively light material easing handling and installation and can be cold curved on site. Marvault HF uses 3mm as standard for single and double skin formats. Marvault RL typically uses 3mm or 4mm solid polycarbonate. Bronze and opal tint options help control the amount of light entering the building and can limit glare from the sun.The clear tinted option will maximise natural daylight. Marlon ST Longlife, premium quality multi-wall polycarbonate sheet can be used in both twinwall and triplewall formats for use in Marvault HF and RL. Depending on thermal performance requirement 10mm and 16mm thick sheets can be used. Marlon ST 16mm triplewall has a U value similar to that of double glazing.
