Sheds

Hutton

Garden sheds are a great way of improving the appearance and practicality of any garden, our range of sheds are manufactured from Scandinavian Redwood and pressure treated offering your customers piece of mind that their shed is protected against wood decay and insect attack.

All of our sheds are constructed using ex 45 x 35mm framework, clad with ex 19mm shiplap and a roof & floor machined from ex 25mm tongue & groove timber. These allow us to produce a high quality robust shed which when coupled with our 15 year Treat-Right Warranty ensures a long service life. When siting the shed only bearers treated to Use Class 4 (in ground contact) can be used. If the shed is positioned directly on to a concrete base then this must have drainage to avoid standing water.

 

WATER REPELLENCY - PRESSURE TREATED TIMBERS FOR SHEDS OR GARDEN BUILDINGS

Pressure preservative treatment is designed to prevent rot and insect attack to give softwood construction and landscaping timber products an extended and low maintenance service life. The treatment is not intended to perform as a waterproofing agent.

When using pressure treated cladding timbers in the construction of sheds or garden buildings the following guidelines should be followed to help prevent any water ingress.

  1. The Timber Research and Development Association (TRADA) recommends a 16-19mm nominal thickness for cladding timbers.
  2. Nail heads should only be driven marginally below the surface of the cladding timbers.
  3. A suitable airflow should be allowed throughout the structure to assist on-going drying.
  4. The dry, external timbers can have a water ingress protection added with the application of an appropriate and well maintained water repellent coating. This would involve a proprietary water repellent coating product which could be applied to the dry external timbers following the relevant manufacturer's guidelines. Recommended products include Thompson's Waterseal, Hickson Decor Wax Coat and RESTOL Wood Oil - www.restol.info
