Our story...so far

Founded in 1955, Thaweephan began life as a saw mill, supplying Teak timber to domestic and foreign markets.

In the 1970s, in response to concerns over deforestation, we shut down our forestry operation and turned instead to timber processing and manufacturing of high-quality products from wood sourced in the global market.

Four generations later, we’re still a family-owned business specialising in custom architectural wood products, interior design and heritage restoration services.

Kiln Drying

In Thailand, Thaweephan led the way in importing the latest American kiln-drying equipment and technology. We’ve also pioneered the use of non-harmful chemical preservatives and termite treatments.

We operate a conventional steam kiln system where air speed, temperature and humidity are tightly controlled to accelerate the drying process. This reduces the distortion, staining and drying stresses as we dry our woods to moisture contents of between 10 and 14 percent depending on specie and application.

Benefits of Wood

Wood is the only renewable, recyclable, reusable, and biodegradable building product widely available. It is also beautiful, durable, versatile, and in many cases highly cost-effective. Harvesting and processing wood uses much less energy than most other building materials, giving wood products a significantly lower carbon footprint. Indeed, wood products actually store the carbon they removed from the atmosphere while growing.

Is better for the environment

Using responsibly sourced wood in construction, rather than commonly used materials such as steel and concrete, can reduce a building’s initial carbon footprint by more than 80 per cent. Surprising, but true. A smaller carbon footprint means less climate change.

Stores captured carbon

Trees and wood products are Nature’s carbon captors. Up to half the dry weight of wood is carbon which has been removed from the atmosphere during growth. It is stored for the lifetime of the product: properly maintained, that’s a very long time.

Is sustainable

Responsibly harvested wood is a renewable resource. Managed growth ensures that forests continue providing the benefits of carbon storage, oxygen generation and wildlife habitat.

Lasts longer

Wood is a highly durable material suitable both for homes and commercial buildings. When properly looked after it can last hundreds of years. Modern wood preservatives greatly enhance this natural durability.

Enhances insulation

The pockets of air in its cellular structure make wood a natural insulator—15 times more efficient than masonry, 400 times more than steel, and 1,770 times more than aluminum.

Is time-efficient

Wood construction is quick and efficient. Wooden buildings can be built year-round in most climates, and take less time to complete.

Reduces costs

When it comes to direct building expenses, timber frames have been shown to be the most cost-effective solution.

Adds beauty and character

Wood is a beautiful natural material that adds character to a building. Every tree has a unique grain.

Sustains skilled employment

Because woodwork is often done on site, with items prefabricated locally or regionally, choosing wood means supporting local jobs for skilled carpenters and artisans

Treated Timber

The reasons for using Celcure-AP

Celcure-AP is a waterborne copper chrome arsenate wood preservative which gives long-lasting protection againt fungi, insects and termites, but adds little to the cost ot the timber. It is applied by vacuum pressure impregnation which forces the preservative deep into the wood. The chemicals become fixed in the wood after treatment and do not wash out. All timber treated with Celcure-AP should be handled and used in accordance with Celcure’s recommendations.
