Marlon Toploc
Marlon Toploc is the highly versatile, architectural glazing system from Brett Martin, comprising modular polycarbonate panels extruded with an upright connection profile. The thermally insulating multiwall panels provide U-values as low as 1.78 W/m²K. They can be installed in vertical, pitched and curved applications. The system is also fully reversible and can achieve a seamed finish, with the use of the polycarbonate snap on connection cap, or a seamless surface finish with the use of the aluminium connection profile. The panels are lightweight and easy to install and available in lengths up to 12m. For the complete glazing solution choose from our selection of installation accessories.
Marlon Toploc is also available in Marlon BioPlus, the ideal choice for projects that aim to deliver the highest standards in sustainability, allowing companies to demonstrate they are at the forefront of the low carbon circular economy.
Marlon BioPlus is made with a bio-circular attributed resin in which 89% of the fossil based raw material has been replaced by renewable hydrocarbons e.g. from used cooking oil, which dramatically reduces the impact of the finished sheet on the environment, whilst maintaining the same material properties and ease of processing.

- Marlon Toploc is a high quality, extruded, modular multiwall polycarbonate panel with a co-extruded UV resistant coating
- As polycarbonate is a thermoplastic, it is important to take thermal expansion and contraction into account during any installation process.
- Marlon Toploc has been independently tested to various Fire Standards; for the most current certification please contact our Technical Department.
- Marlon Toploc panels are REACH and RoSH compliant, and 100% recyclable
- Any colour option is a through-colour so the colour of a cut edge will match the colour of the surface.
- Marlon Toploc panels are covered by a limited warranty. For full details contact our Technical Department
- Standing seam surface finish
- Suitable for rooflights, canopies and façades
- Can be installed in vertical, pitched and curved applications
- Polycarbonate connection cap is light in weight and maximises light transmission
Spanning
It is vital that accurate wind and snow loads are used when calculating spanning details. Please contact the Technical Department for spanning details for your specific project.

As a condition of ensuring that Marlon Toploc panels perform at optimum throughout their service life and retain light transmission properties, it is recommended that the panels be cleaned periodically using suitable household cleaning agents as follows:
- Use lukewarm water to rinse the sheet and soften dirt.
- Make up a solution of lukewarm water and ordinary household cleaner or a mild soap and use this to wash the panel.
- A sponge or soft cloth should then be used to gently remove dirt and grime.
- The cleaning process should then be repeated and the panel rinsed and dried with a soft cloth.
WARNING
Care should be taken to observe the following precautions:
- Do not scrub Marlon Toploc panels with brushes or sharp instruments as they will mark easily.
- Never steam clean, use low pressures for pressure washing.
- Avoid any abrasives or cleaners of a highly alkaline composition.
- It is generally advisable in all instances to test any cleaner on a sample piece of the Marlon Toploc panel first and it should also be remembered that cleaners and solvents which state that they are suitable for cleaning polycarbonate may not be safe for use on the UV protective surface of the panels.
