As a self-renewable resource, it has proven its worth in the conservation of our ecosystem. Wood is either naturally durable or can be artificially preserved for the desired application. It is beautiful, strong, environmentally friendly, CO2 neutral, recyclable and infinitely renewable as long as it comes from sustainably managed forests.
Jungle Gym climbing frames and playhouses are made of high quality pine wood from Northern European forests. This wood comes from coniferous trees such as Pine, Spruce and Douglas fir. In robust dimensions and with the right specifications, these timbers are the ideal building material for a solid and durable climbing frame. Given its good technical properties, natural appearance and durability it is a first class material for climbing frames, playhouses and swings.
Robust Timber Parts
All solid timber parts used by Jungle Gym are carefully selected, cut to length and smooth planed. The extra sturdy dimensions of the timber used is unique in relation to the commonly used dimensions within the industry. This way, we ensure a solid, robust construction for years of safe play fun.
One can choose between impregnated standard Pine or 100% natural premium Douglas. Both are derived from responsibly managed Northern European forestry. Impregnated Pine and Douglas are both wood rot resistant and we therefore give a 10 year warranty against wood rot to its first owner. More info about the differences between the timber species can be found below.

As one of Europe's hardest pine woods, Douglas has superior strength properties. Nowadays it is used widespread by professionals in the furniture and building industry, because of its constructive and aesthetic characteristics. It has limited resin and splinter formation because of its stable characteristics compared to other wood types. Douglas naturally has a warm appearance because of its orange colour and flame structure. Douglas is naturally durable and can be used outdoors without additional treatment and therefore it doesn't contain toxic substances or allergens. Your children will be ensured to enjoy years of safe and maintenance free play fun by choosing top quality kiln dried Douglas in combination with the extra robust dimensions.
The selected standard pine is a type of timber with an excellent price quality ratio. This timber has been appreciated because of its naturally constructive characteristics for centuries and is the most used wood type in Europe. Impregnating it in an environmentally friendly and chrome free manner considerably increases its durability, protects it against wood rot and makes is suitable for outdoor usage. In combination with the extra robust dimensions this choice will ensure a solid play set and years of safe play fun. Every play tower and house is unique due to the wood having natural irregularities in appearance, giving your play house its exclusive character. Due to its impregnation there is no need for maintenance. Be extra cautious of the parts that are in contact with the ground. Sawn pine should be treated with preservatives, even when the wood has already been impregnated.
The wood Jungle Gym uses for its climbing frames and playhouses is either FSC or PEFC certified. These are international non-profit organizations that promote sustainable forest management through independent third-party certifications. These certifications ensure 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.
Warranty on Timber
All Jungle Gym play equipment is accompanied with a timber set made out of Douglas or impregnated Pine. These timber parts are resistant to wood rot. We are convinced of our quality and therefore give a 10 year guarantee against wood rot. If, however, the wooden parts delivered by us are affected by wood rot within the warranty period, they will be replaced free of charge. This is, under the conditions that our assembly instructions are followed, no alterations have been made to our designs and installation is done according to our prescriptions.
Wood is a natural product and all timber parts therefore have their own specific characteristics. Every tree, every piece of wood is unique. Natural variations in structure, appearance and other irregularities will show up in time. Timber used outdoors will be affected by fading colours due to weathering and will show deviations in dimensions, deformations, knots, resin pockets and cracks over time. These are authentic features that give solid wood its natural beauty. These natural properties of wood have no effect on the physical and mechanical integrity of your climbing frame.
Humidity affects the volume of wood. In extreme dryness it shrinks, i.e. it reduces its volume. This is a specific characteristic of wood that is unavoidable. Different levels of the moisture content of wood can result in dimensional deviations (up to 10%) and deformations.
Pay attention: To ensure an exact fit, the wooden parts are not pre-drilled.
During impregnation, the wood is coloured green by the copper-containing preservative. In places where resin is present in the wood, this become extra visible in the form of green spots and the formation of salt crystals. This is common and occurs in all impregnated wood. After being exposed to the sun for a few weeks the spots will disappear. From that moment on it's possible to stain the wood, if desired.
Tip: Lightly sand highly contaminated areas with the supplied sanding block!
Wood is a natural product and in some cases can expand, shrink or even split. Wood reacts to changes in humidity with a change in volume. This inevitably leads to cracks and deformations. This is a specific property of wood that cannot be prevented. These cracks and deformations do not affect the strength and are no cause for complaints.
Pay attention: Cracks with a length of up to ¼ of the wood length and ¼ of the cross-section are not mechanically relevant!
Impregnated wood is very moist. Especially in warmer seasons the wood is susceptible to mildew or mould during drying. The result is white spots on the wood surface. These fungi do not affect the quality or strength of the wood and they are not harmful to health. These external imperfections on the product disappear by themselves, but are also easy to remove.
Tip: Tip: Upon delivery, remove any protective film to prevent condensation from forming underneath the film, which will cause stains and mould on the wood.
During impregnation, drying and storage, wooden parts may be covered by the stacking on the pallet or packaging. Other parts, on the other hand, are exposed to light. Light causes a reaction in the wood as well as in the preservative, which first turns brown and then discolours and fades locally.
Tip: After being exposed to sunlight for a few weeks, the wood of the playground is given a uniform colouring.
Knots may occur in the selected wood. A knot is a round, oval or irregular form of dense and dark wood at the place where a branch used to grow. Knots, annual rings, cracks and small imperfections belong to the natural properties of wood and therefore give it its own specific character.
Rough spots and splinters may occur on some wooden parts. Despite careful selection and production, some of these rough spots cannot be avoided. Depending on the type of wood, these rough spots occur mainly around the knots and at the outer ends. These aesthetic defects form an inseparable part of wood and they do not affect its strength and are no cause for complaints.
All coniferous species contain resin pockets. Due to the effect of sunlight it is possible that in the first year resin will come out of the fresh, newly cut, wood. The sticky leaked resin can crystallise on the wood surface taking on a yellowish color. These processes are natural and are considered normal.
Tip: Resin can easily be removed by scraping it off with a sturdy brush or putty knife. If necessary, you can also use a special alcohol-based resin removal agent.
The colour of the wood gradually changes over time as a result of weathering and the effect of sunlight. Impregnation is a protection against wood rot and not a decorative finish. This natural ageing has no effect on the durability and does not lead to a loss of timber quality. If you wish to preserve the original colour of the timberparts, you can treat it with a special wood oil or stain / water-based paint / varnish. It provides an additional protection against wood rot, delay its aging process and slightly prevent cracking.
Tip: The darker the colour chosen, the less visible the natural aging is.
