Timber information

What are typical wood characteristics?

Wood is a natural and sustainable raw material. During the growth process each tree develops it’s own characteristic features. Typical wood features such as branches and grains make each piece of wood a genuine one of a kind. The distinctive natural features are deliberately accepted and do not constitute a defect.

Should I paint the wood?

No, you do not need to paint the wood. The wood used in our climbing frames is impregnated and therefore weatherproof.

Why high-pressure treated wood for climbing frames?

Wickey deliberately choses pressure-treated wood because of the many advantages compared to natural wood. The child- and environmentally friendly pressure-treated wood is also used in professional, public areas.

  • No tedious sanding and annual painting
  • Increases the life of the wood
  • Protects against weathering, rot, mildew and fungi
  • No expensive coating colour needed
  • Saves time, effort and money

Cracks and branches Cracks and branches
  • Branches, grains and pith are part of the characteristics of the wood
  • Dry cracking is permitted according to DIN 4074

Tip: Cracks with ¼ of the length and ¼ of the width are statistically harmless!

Swelling and shrinking Swelling and shrinking
  • Volume change due to moisture absorption/drying is typical of the wood
  • To ensure accurate assembly, not all wooden parts are pre-drilled due to wood movement

Tip: Unpack your wood immediately and let it dry for at least 2 days before assembly!

Impregnation Impregnation
  • Environment and child-friendly high-pressure impregnated wood (Tanalith E 3475)
  • The impregnation solution is forced deep into the wood with water

Tip: Due to the impregnation, painting is not necessary!
