WebC24 Timber vs. C16 Timber. C24 and C16 are the most popular options for carcassing timber within the UK. Both are comparable but C24 is the superior choice. C16 wood tends to be grown faster, with the forced growth process leading to an increase in knots. This will make the timber in C16 beams less durable, and also make them visually flawed. WebThe fir wood was acquired from the Austrian company Holzhof-Schmidt GmbH (Aspangberg-St.Peter, Austria) with a certificate of strength for class C16.
