HTL's H-Clad KiwiTEC Macrocarpa Rusticated Weatherboards are a cavity-based horizontal cladding best suited for light commercial and residential buildings. Made from durable and sustainable NZ Macrocarpa, this provides long-lasting exteriors with minimal maintenance and maximum protection against moisture and weather damage. Macrocarpa's warm colour and grain create visually timeless facades.
The H-Clad Rusticated system is a first and second line of defence against water penetration by separating the cladding from the external wall frame with a drained cavity.
The weatherboards are pre-finished with two coats of DRYDEN WoodOil.
H-Clad Rusticated is available in the following profiles options, along with a range of exterior mouldings.
Macrocarpa cladding offers architects a sustainable, durable, and versatile solution for both commercial and residential projects. Its natural and environmental benefits, coupled with the advanced design of the HTL cladding system, make it a superior choice for contemporary building needs.
H-Clad KiwiTEC Rusticated Weatherboards are suitable as a horizontal external fixed wall cladding, meet the requirements and limitations of the following:
All HTL H-Clad Weatherboards meet the requirements of the NZ Building Code for Clauses B1 Structure, B2 Durability and E2 Exterior Moisture when installed in accordance with the HTL installation guide.
H-Clad KiwiTEC Rusticated must be designed and installed in accordance with the HTL Rusticated Weatherboards Technical Guide for Specifiers and Installers.
H-Clad KiwiTEC is manufactured with care and inspected to ensure quality. However, it is a natural wood product and subject to variations in weight, density, colour, grain and performance. Care must be taken in installation and maintenance to allow for movement.
Care must be taken to ensure that timber and accessories are kept clean and dry, and are not damaged whilst in storage awaiting application. Extra care is to be taken while handling timber to ensure that they are not damaged. Timber is to be stacked on flat level bearers that are a maximum of 900mm apart and at least 100mm off the ground.
Timber should either be stored inside an enclosed building or covered and protected from the elements when stored outside
Important: Timber weatherboards should not be installed if their moisture content is outside the range of 14 - 18 %
It is not recommended that HTL weatherboards be left uncoated.
HTL recommends that all timber H-clad cladding should be envelope coated before installation, including all cut ends and exposed fresh timber. Avoid coating the top surface only, once installed as this will likely cause movement (cupping) in the timber surface.
HTL do not recommend the use of dark paints or coatings as this may accentuate movement and splitting of the timber, especially if it is exposed to the sun or hot temperatures. Timber generally requires a coating with a Light Reflective Value (LRV) of 40% or greater to minimise the amount of heat build-up in the timber and the resultant thermal movement.
