Frequently Asked Questions
There will always be a slight variance in the board’s dimensions due to the fact that we mould from natural oak, and due to the pressure of the moulding process. Despite this, we calibrate the boards to maintain as consistent a profile as possible. The manufacturing tolerances are: Width: ± 3mm. Length: ± 5mm. Thickness: ± 2mm. The dimensions of the Weathered Oak style may vary more between moulds due to the fact that they are moulded from timeworn oak with minimal changes to the dimensions. When working with the boards, packers may be required to create a flush finish between two boards.
Dimensional variation is also possible with our Our Envello® cladding boards and therefore the same manufacturing tolerances are applicable (Width: ± 3mm. Length: ± 5mm. Thickness: ± 2mm).
When using our Shadow Line product, in order to achieve straight and consistent 6mm gapping between boards, it may be necessary to use our Millboard Multi-Spacers during the installation process.
For further details please refer to our Envello® Cladding Installation and User Guidance in the Help & Advice section of our website.
The Shadow Line+ cladding boards have been tested to BS EN 13501-1 and have a classification of D-s3, d0.
The Board & Batten range is also crafted with fire retardants in the board composition, but it is not fire rated and carries no ‘reaction to fire’ certificate.
The responsibility for the cladding’s suitability in the required location is to be determined by a certified building professional (building control, building insurance, fire officer, etc). Millboard will not be held responsible for incorrect specification, application, or product installation in areas not in accordance with government guidance, in the UK or abroad. Current guidance should be gained from the government website relating to the geographical project location, England’s building regulation Approved Document B can be found on - https://www.gov.uk/government/publications/fire-safety-approved-document-b
