With security & longevity in mind, all of our sheds are built using 2 x 2 timber and shiplap grooves. Shiplap tongue and groove sheds share many of the same qualities as regular tongue and groove sheds, but the Shiplap has one special feature. Shiplap cladding has a little channel running alongside the timber. This little channel or groove, allows water to run off the shed very quickly. This also helps the shed dry quickly after exposure to rain, helping to protect it from any water damage. Shiplap tongue and groove cladding also gives sheds an attractive appearance and has a robust and sturdy structure.
