What are decorative exterior boards?
Exterior decorative boards can be used for a range of applications in domestic and commercial buildings that include soffits and siding, fascia, doors and accent boards. Commercial applications include store displays, outdoor signs and marketing boards as well as hoarding and facades.
Sustainable timber building materials such as OSB, plywood and MDF are lightweight, easy to transport and fast to install. Timber manufactured boards not offer design flexibility, ease of machining and fixing without specialist tools but they also provide high mechanical strength and structural integrity.
Plywood, MDF and OSB that has been graded at level 3 and above have basic level moisture resistance. When used as decorative exterior boards, boards should be primed and waterproofed to ensure they are protected from moisture ingress that could affect their strength and performance. To achieve a high quality finish, the surface of all timber manufactured boards needs to be smoothed before priming, especially if they will be painted or printed on. If laminated, smoothing and priming of the surface is a prerequisite of material compatibility and finish quality.
