Consistent manufacturing from logs to final products.
CLT stands for "Cross Laminated Timber," which is referred to as "cross-laminated timber" in Japanese. It is a wood product made by gluing together layers of boards (lamina) with their fiber directions oriented perpendicular to each other. Developed in Austria in the 1990s, it is a new wood construction material that is now being adopted in buildings across Europe and North America, rapidly gaining popularity. CLT achieves large thicknesses, widths, and lengths that were not possible with existing wood products. It enables the use of wood not only in small buildings like wooden houses but also in large and mid-rise buildings where wood construction was previously challenging. High-rise buildings utilizing CLT are being constructed in North America and Europe. It has also gained attention in Japan, where the JAS (Japanese Agricultural Standards) was established as a manufacturing standard in December 2013, and the building code notifications related to CLT were promulgated and enforced in April 2016. This marked the beginning of general use of CLT, and mid-rise wooden buildings using CLT have also started. Our company began manufacturing JAS-compliant CLT in July 2018.

basic information
The product output of the Toyo Industrial Park includes 2,700 m³ of cedar KD foundation and column corners per month, 3,000 m³ of cedar laminated foundations, and 700 m³ of American cypress laminated foundations. Additionally, it manufactures small cross-section structural laminated timber (laminated columns), cedar KD fence materials (for the U.S. market, peaking at 20 containers per month), and cedar KD 2x4 construction lumber (200 to 300 m³ per month). CLT is categorized into cedar, cypress, larch, and cedar-cypress hybrids. The production capacity is 10,000 m³ per year, making it the second largest manufacturing capacity in the country. Furthermore, the CLT processing capacity is 2,000 m³ per year, and basic CLT precut processing (actual size processing, hardware slit processing, drift pin processing, etc.) can be performed in-house. Structural design and construction are outsourced.
Price information
We will carefully examine the design documents for each project and calculate the optimal yield of CLT to provide you with a price. Our company is committed to expanding the use and demand for CLT by leveraging our cost advantages and flexible manufacturing capabilities through integrated production from logs. We aim to broaden the possibilities of wooden architecture, promote the use of domestic timber, and contribute to a positive cycle of wood resources through the spread of CLT. To achieve this, we first aim to dispel the preconceived notion that CLT is expensive and encourage many people to use CLT.

Applications/Examples of results
CLT panels are a new building material that can be used as structural members and shear walls in wooden frame construction, in combination with reinforced concrete methods, as well as finishing materials for ceilings and floors. They can be utilized in various ways and are suitable for mid-rise and high-rise buildings and large-scale structures where wood has not been widely used until now. They are used in apartments, commercial facilities, schools, and public buildings. Currently, CLT is mainly supplied for non-residential wooden construction and medium to large-scale wooden projects, but efforts are also being made to develop demand for large wooden warehouses using CLT, as well as for floor surfaces in general housing and reinforced concrete high-rise buildings. The advantages of buildings utilizing CLT include a shorter construction period since the concrete curing time required for reinforced concrete structures is not necessary, the ability to simplify foundation work because CLT can be made lighter than concrete or steel while achieving the same strength (in this case, bending strength), and better insulation properties compared to concrete and steel when comparing the same thickness. The government is also promoting its utilization. Our company is working on expanding the applications and demand for CLT by leveraging cost advantages and flexible manufacturing capabilities through integrated production from logs.
Detailed information
-
Cypress Sunadaya's CLT has a thickness of 90 to 270 mm, a width of 2200 to 3000 mm, and a length of 5000 to 12000 mm. Sizes below this will be cut using our own processing machines. We will calculate the optimal yield for you within this dimensional range and manufacture the final product with minimal waste. The standard thickness of the laminates is usually 30 mm, but since we have our own lumber mill adjacent, custom thicknesses are also possible. The laminate width is 120 to 140 mm. The maximum size of CLT that can be manufactured is 3 m in width and 12 m in length. If the thickness is 90 mm or more, we can accommodate it in increments of 30 mm.

The supply capacity of cypress CLT is our strength, and in addition to the standard S90 and S120 strength, we can consistently manufacture surface configurations using first-class materials and plain small materials for the outer layer. In particular, the surface configuration is renowned for its beauty. The strength classifications are as follows: cedar (same grade composition) is S60, cypress (same grade composition) is S90 and S120, cypress-sugi hybrid (symmetrical different grade composition) is Mx90 and Mx120, and larch (symmetrical different grade composition) is Mx90.
