Walls: 12mm Shiplap Tongue and Groove. Our planed finish closes the pores making it more resistant to moisture. Its curved profile aids water run-off. The interlocking construction makes the building altogether more stable and robust.

Double Frame Corners: This building features double framed corners for added strength and stability.

Floor:  Solid Sheet which is hardwearing, stable, excellent moisture resistance and is less susceptible to warping, distortion and layer separation than ply. No knots or voids to worry about and does not split when nailed or screwed.

Floor Joists: This building uses planed timber in the floor joists to provide a sturdy support on your base.

Roof:  Solid sheet which is hardwearing, stable, excellent moisture resistance and is less susceptible to warping, distortion and layer separation than ply. No knots or voids to worry about and does not split when nailed or screwed.

Door:  This building comes with fully ledged and braced single door adding security and helping to extend the durability. A padbolt is provided with this garden building for added security.

Pressure Treatment - This shed comes pressure treated in an attractive, brown colour. Pressure treated timber has undergone a process where preservatives are forced into the timber under high pressure. This provides extra longevity and an unbeatable level of protection for the wood against rot, insects and fungus. This also means the building comes with a 15 year anti-rot guarantee.

Though pressure treated timber is well protected, customers should carefully read and follow all care guidelines supplied by the manufacturer with your building. This usually involves regular treatment with a water based treatment. The manufacturer recommends Protek Wood Treatments, available to purchase through elbec at a fantastic price.

Delivered flat-packed with assembly instructions, fittings and roofing felt.
