Wood contributes to energy conservation.

Tree is growing by absorbing water and CO2 through its photosynthesis.

The energy consumption and CO2 emissions during the processing of tree into lumber are significantly lower compared to the processing and manufacturing of fossil and mineral resources. Therefore, wood is one of the most energy-efficient materials.

Forests continue to absorb and fix CO2 in the atmosphere during growth and store it within themselves. Utilizing more renewable forest resources in various fields promotes the CO2 cycle in the global environment and contributes to environmental conservation.  

Wood preservation treatment that maintains the natural properties of wood while enhancing durability.

Wood, a material that provides comfort and warmth to living environments and is easy to work with. However, cellulose and hemicellulose, which make up wood, are a favorite food for wood-decay fungi and termites. Damage often occurs to wood in hard-to-reach areas of homes. If left untreated, wood can decay or be eaten by termites. We have developed advanced wood preservation technology to enhance the durability of wood while maintaining its natural properties.

Wood-decay fungi and termites that destroy wood

  • Wood decayed by fungus

  • Termite damage

Even modern houses designed to withstand earthquakes can collapse due to termites or fungi.

No matter how well-designed a modern house is for earthquake resistance, that is only when the structural materials are sound.

If the structural materials themselves are damaged by termites or fungi, the earthquake resistance cannot be relied upon.

Such damage is likely to occur several years after the house is constucted.

Modern houses are, in fact, prone to decay and termite damage.

The conditions necessary for decay and termite damage are moisture, a certain temperature, and a wood source for nourishment. Areas such as under the floor, inside walls, and around bathrooms and kitchens, where moisture tends to accumulate, are particularly susceptible to wood-decay fungi and termites.

Additionally, the interior of a house provides a comfortable environment for termites with fewer natural enemies compared to the natural world.

Furthermore, recent trends towards highly airtight and insulated homes have increased the likelihood of moisture buildup,

Kanematsu Sustech offers two types of pressure treatment: dry and wet methods.

Features of Preserved Timber

Preservative-treated wood that lasts 3 to 5 times longer than untreated wood.

Not only for outdoor lumber exposed to rain, but also for indoor lumber, if it is not treated with preservatives, it will decay or be damaged by termites prematurely.

The reason for rot and termite damage is that "wood-decay fungi" and "termites" use wood as a food source. Places that come into contact with the ground, exposed to rain, or have high humidity are particularly susceptible to damage. To make wood last longer, it is necessary to apply "preservative treatment" to prevent "decay" and "termite damage".
