With new designs, rigorous testing and the extreme robustness of board-and-batten, Hermpac is focused on growing this cladding as a high quality and fashionable choice.
No longer thought of as simple ply cladding, solid timber board-and-batten is making a renewed come-back and the results are looking equally stunning in rural or urban settings. Comfortably taking on all weather conditions. Our Custom Design Profiles are allowing designers to explore the use of exposed negative details, variable relief and shadow lines among other options. Combined with staining through our Machinecoat, architects are enjoying finding a texture and colour solution to match any landscape.
Profiles are available in various widths and thicknesses incorporating the standard Board and Batten lap detail. These profiles can be supplied with either a bandsawn face (BSF) or dressed face (DF), and are available in a range of both square groove standard and custom profile options.

Maintenance of the Hermpac Board and Batten Cavity System is the building owner's responsibility.
Annual inspections must be made to ensure that all aspects of the cladding system, including flashings, remain in a weatherproof condition. Any damaged areas or areas showing signs of deterioration which would allow water ingress, must be repaired immediately. Sealant, coatings, flashings or the weatherboards must be repaired in accordance with the relevant manufacturer's instructions.
Maintenance requirements will depend on the coating type that is applied. Please refer to the coating manufacturer's specification. Specific maintenance schedules for re-coating oil stains are issued on a project specific basis.
Regular cleaning (at least annually) of the surface finish with water and a mild detergent is recommended to remove grime, dirt and organic growth, to maximise the life and appearance of the cladding.
