Timbers in this collection are particularly suitable for exterior cladding applications that will be exposed to the weather. The timbers, if installed correctly, will require minimal maintenance and should provide a long service life. The timber is either green (freshly sawn) or air dried and therefore allowance should be made during installation for initial shrinkage due to drying. This is especially important on south facing walls which have prolonged strong sun exposure during the summer months, consideration should be given to cladding walls with this aspect during the autumn/winter to allow a gentler initial drying of the timber
