The charring process time varies from 2-4 weeks.
However, the acquisition of the timber from either you, the timber merchant or the timber mill will be the main factor in the timeframe needed to get your charred timber cladding. At the time of writing this (April 2021) our timber mills offer 6- 8 weeks with New Zealand grown Redwood being 20 weeks. Its best to inquire directly with us for accurate timeframes.
