To calculate the weight of Oak, multiply the width (cm) x depth (cm) x length (cm) and divide by 1000 to get your approx. weight per beam in kg.

For 175mm wide cladding we use the following to calculate the linear metres you would need to order:

1. Calculate the square metres of the building. Length x height minus any door or window openings.

2. Times the SQM by 8 and this will give you the Linear Metres which includes an overlap of 50mm.

For 200mm wide cladding we use the following to calculate the linear metres you would need to order:

1. Calculate the square metres of the building. Length x height minus any door and window openings.

2. Multiply the SQM by 6.67 and this will give you the Linear Metres which includes an overlap of 50mm.

Tongue & Groove Cladding

We stock T&G in various lengths so the calculation will alter dependant on the length.

1. Calculate the square metres of the building. Length x height minus any door and window openings.

2. Calculate the coverage of each Cladding board, multiply the length by 0.125 e.g. 3m x 0.125 = 0.375 sqm

3. Divide the SQM by 0.375 and this will give you the number of lengths you need to order. Example: 40 sqm / 0.375 = 107 boards (3m)

Unfortunately not all featheredge cladding is cut to order. One of the office staff will call you when its ready to collect which is normally around 2-3 business days after we have received your order.
