Wood preservation

No other material is as versatile as wood. Wooden structures, such as the Hanover Expo Canopy or roller coasters, can be extremely impressive. But wood also convincingly shows its versatility in interior design or gardens and landscaping. High strength and low weight combined with natural beauty are the outstanding features wood has to offer and its use makes a significant contribution to sustaining our forests and thus maintaining their important protective functions for earth, water and climate.

Especially local coniferous timbers, such as spruce, fir, pine or larch can be used for roof trusses, wood-based construction materials like particle boards or plywood, facades, fences, patio decks, posts and masts, bridges, avalanche barriers, landing stages and platforms, cooling towers and many other applications.

Used externally, these timber species of mainly low durability are at risk from wood-destroying fungi and insects. Dry or wet rot, house long horn and common furniture beetles pose a threat to wood used in indoor construction. Here, modern wood preservation provides a valuable contribution to maintaining the value of timber structures and preserving resources.

You can find out here which processes and products are suitable for the long-term protection of wood and in which particular applications.

Vacuum Pressure Treatment

Timbers used outdoors, exposed to the elements or in contact with the earth, or those used in water or for special applications like cooling towers, need special in-depth protection that a vacuum pressure process can reliably provide.
Modern, fixing Wolman products, which have undergone extensive ecological testing, are guaranteed to provide wood with reliable and long-lasting protection.

Treatment of constructional timber

In many buildings, wooden structures carry out supporting functions. Preventive preservatives offer lasting protection from wood-destroying insects and fungi.
The impregnation of constructional timber, boards, laths and other wood-based materials in dipping processes with coloured or colourless Wolman wood preservatives is the classical, tried and tested approach. Other processes, such as coating and spraying are also used in this field.

Anti-sapstain

Discolouration of fresh wood directly after it is cut in the sawmill is a constantly recurring problem. Wood-staining fungi, in particular blue stain, attack the wood very soon after cutting and leads to an irreversible reduction in the wood’s value. Fungal spores spread the infestation and can be a health risk. Treating the wood with Wolman Anti-sapstain preservative directly after it has been cut reliably prevents discolouration and fungal spores.

Protection of wood-based materials

In building, significant amounts of wood-based building materials, such as particle boards, OSB or plywood are used. These materials can be destroyed in the same way as the wood types they are made from, through excessive moisture, for instance. For such materials, Wolman can also provide the appropriate protection.

Remedial treatment

Wood can suffer greatly under exposure to the elements, such as rain, snow, UV rays, heat and frost, making possible infestation by wood-destroying organisms much more likely. To maintain the value of wooden utility poles and constructional components, remedial measures can be taken to significantly prolong their service lives.
