SLE Cladding Ltd are not  comprehensive "Timber Merchants", but in order to meet our customers complete cladding requirements we do stock quantities of Home Grown Tanalised Softwood in the popular standard building lengths.

Our supplies mostly originate from commercial forests in Scotland ( a renewable resource) and are thus environmentally friendly. Stocks are tanalised (treated) to prevent decay. Untreated timber can be obtained to order in about 7 days.

WARNING. When using tanalised treated timber purlins (Including other proprietary brands of treatment) in conjunction with any type of steel roofing sheets, a protective barrier MUST BE PROVIDED between the roofing sheets and the timber purlins to avoid corrosion to the roofing sheets. This is particularly important for building housing any type of livestock where high levels of condensation will be present.  The barrier can be items such as U-PVC tape, roofing felt strips or even paint. Bitumastic paint leaves a good thick barrier

We list below our standard stock sizes in both metric and Imperial; measurements. Other sizes can be obtained to order, in both plain and tanalised. NOTE. That whilst timber mills have gone over to metric sizes, we  still stock purlins in the standard building purlin lengths of 15, 16 & 20ft.
