Robust European timber

Jungle Gym Climbing frames are made of robust timber from European pine trees. It is beautiful, strong, environmentally friendly, CO2 neutral, recyclable and infinitely renewable as long as it comes from sustainably managed forests. The good technical properties, natural appearance and durability makes it a first class material for climbing frames, playhouses and swings.

From sustainably managed forests

The timber for Jungle Gym climbing frames has the FSC label. The Forest Stewardship Council is a global, not-for-profit organisation dedicated to the promotion of responsible forest management worldwide. This ensures that your Jungle Gym is made of wood from sustainable forests with consideration for people, wildlife and the environment. After all, trees are our most valuable natural source; they generate the oxygen that we breathe, are vital for millions of animal species and protect our climate.

Timber is alive

Pine timber is a product of nature, every piece is different containing unique characteristics. Variations in color, grain, structure and knots are part of the charm and beauty of real timber. They give your climbing frame character, no two pieces are alike. Over the years, new or other irregularities may appear and are completely natural.


All our solid European pine timber is carefully selected and inspected. The following irregularities are deliberately allowed and do not affect the quality or structural integrity of the climbing frames.

Color changes

Timber is a natural product with its own characteristics. Every tree has a different shape and structure. The preservative can also cause some color difference. Any color difference will disappear within a few months.

Expansion / contraction

Changes in humidity causes slight expansion and contraction of the timber. When the air is humid timber expands, when the air is dry it contracts. This is a natural property of pine timber and does does not affect the quality or structural integrity of the climbing frame. This is also the reason why we don’t pre-drill the holes for you, depending on the weather it would not fit perfectly during assembly.

- Length maximum allowed difference 1.5%

- Width maximum allowed difference 6%

- Thickness maximum allowed difference 6%

TIP: Unpack the timber right away and allow the timber to acclimatize for 2 days before assembly.

Slight surface cracks / checks

The expansion and contraction (see previous) may lead to some slight surface cracks or checks for example when the outer part of the timber contracts around the heart. This occurs usually at only one or two sides, is another natural property of pine timber and very rarely affects the structural integrity. However if this is the case, the timber parts must be replaced.
As long as the surface cracks are smaller than ¼ of the length and ¼ of the width of the wood part and they don’t affect the structural integrity, they are acceptable.

Growth rings, knots, grains and rays

Growth rings, knots, grains and rays are an integral part of the charm and beauty of real wood and give your climbing frame character. They do not affect the quality or structural integrity of the climbing frame.

TIP:If you dislike particular growth rings, knots, grains or rays, mount these timber parts out of sight.

Resin

This is also a natural characteristic of pine timber. Only the first year a few drops of sticky resin can come out to the surface of the timber. This is completely harmless to your or your child's health.

TIP: It can be easily removed with a firm brush or a putty knife. If necessary you can also use some turpentine.

White-green spots

The preservative in pressure treatment mainly consists of salts. This protects the pine timber against wood rot, insects, mildew and fungi. Around the knots and/or resin, these salts can sometimes form crystals at the surface of the timber, visible as white-green spots. These spots are completely harmless to your or your child's health and do not affect the quality or structural integrity of the climbing frame.

TIP: Rain and sunshine will gradually cause the spots to get absorbed by the timber and disappear. You can also remove them with a firm brush or the included sand pad.

White spots

In some cases, the humidity and temperature fluctuations during the pressure treatment causes some spots of superficial mold or mildew. These are completely harmless to your or your child's health and do not affect the quality or structural integrity of the climbing frame.

TIP: Any superficial mold or mildew spots can easily be removed away with a cloth.

Small holes

Small holes are created by insects even before the timber is impregnated. Processing and pressure treatment eliminates any insects so they can do no more harm. Small holes like these do not affect the quality or structural integrity of the climbing frame.

Staining / painting / aging

All timber in Jungle Gym climbing frames is weatherproof therefore no need to paint or stain. Exposed to sunlight over the years the color of pine timber will gradually turn more grey, this does not affect the quality or structural integrity of the climbing frame. If you want to maintain the original color or prefer a completely different color, we recommend a water-based outdoor stain / paint. The timber parts are paintable in every color.

TIP: With recently impregnated timber, we recommend to allow the wind to dry the timber for a few months so it is less oily. We also recommend to stain / paint between 14 and 21 degrees dry weather.
