In Tsuzuki, we have adopted the passive wall method as the standard method for wet exterior insulation with the cooperation of Aika Kogyo Co., Ltd. We achieve high-quality wet exterior insulation with reliable domestic products and trusted construction techniques. Furthermore, in the dry method, we can also propose large thin tiles inspired by natural stone as design materials. 1. The durability of the structure is improved. By protecting the structure from the outside, we suppress concrete cracking. Since the temperature of the structure synchronizes with the room temperature, temperature changes are minimized, which also suppresses the expansion and contraction of the RC structure, reducing the risk of cracking. It is not affected by freeze damage, rainwater, or acid rain. 2. The building becomes less prone to condensation. It is less influenced by external environmental factors and maintains an almost constant indoor temperature. Additionally, since the RC structure synchronizes with the room temperature, indoor condensation is reliably suppressed. This also helps reduce the occurrence of mold and mites, contributing to a healthy and comfortable living space. 3. System Overview EPS (expanded polystyrene foam) is applied to the RC structure. A base coat is applied, and a reinforcing mesh is embedded, followed by a finish coat. This is a wet exterior insulation method composed of materials with moisture permeability (insulation materials, covering materials, finishing materials). The finish can be beautifully and impressively crafted using the unique techniques of plastering artisans.

Our company, as an aluminum building materials manufacturer, specializes in rainwater management through our expertise in capstones and water stops, and developed the dry external insulation method "LLH External Insulation Ventilation Layer System" in 2003. The external insulation method improves the thermal environment inside the building while protecting the building structure from sunlight, outside temperatures, and wind and rain, thereby achieving a longer lifespan for the building. There are two types of external insulation methods: the dry method, which physically fixes the insulation material with metal anchor bolts and LLH support hardware, and the wet method, which fixes the insulation material with adhesives such as acrylic resin-based mortar. The dry method allows for the installation of support hardware and battens on top of the insulation material, enabling the selection of various exterior materials such as dry tiles, aluminum panels, spandrels, Galvalume steel sheets, wooden boards, and stone. In particular, stone and tiles are used extensively as exterior materials in the dry method due to their resistance to fading and their semi-permanent usability. 【Features of the LLH External Insulation Ventilation Layer System】 ■ High stability and strength ■ Compatible with heavy exterior finishing materials ■ Minimizes thermal bridging ■ Allows for unevenness adjustment ■ Smooth construction *For more details, please refer to the PDF materials or feel free to contact us.

The dry tile "Drive Brick" adorns the exterior with its dignified beauty brought by the texture and colors of authentic bricks. ■ Safe and Secure Hook Structure The structure hooks the tiles onto an aluminum substrate and locks them with stainless clips, eliminating concerns about tiles peeling or falling. Therefore, there is no need for comprehensive inspections every ten years for exterior materials. ■ Ideal for New Construction and Renovation It can be installed without removing existing exterior finishing materials, making it suitable not only for new construction but also for renovations. Since the aluminum substrate is applied over the exterior finishing materials, installation can be done while living in the space. ■ Compatible with "Health," "High Durability," and "Energy Saving" External Insulation Methods The combination of the LLH external insulation method, which enables a "healthy and comfortable living," and dry tiles has been realized. The choice of exterior finishing materials has further expanded with the flexible design of the LLH external insulation method.

Remule® is a simple dry construction method that involves attaching aluminum rails to the exterior walls of a building and fitting tiles into them. 【Features】 ● Easy Maintenance Remule® uses fired tiles and highly corrosion-resistant aluminum. Since it has almost no water absorption, you can maintain its cleanliness for a long time by simply removing dirt that adheres to the surface (depending on specific installation locations and conditions). ● Lightweight Material We have developed tiles that are made of very lightweight aluminum and are about half the thickness of standard floor tiles (10mm thick), measuring "5.5mm thick." Despite this, they meet JIS strength standards. The overall weight is light, reducing the weight burden on the building. ● Easy Installation The aluminum rails are screwed to the studs. The tiles are simply inserted into the rails with adhesive applied in parts. This leads to shortened construction periods and a relative reduction in waste, which also contributes to cost reduction. ● Safe Design Developed using the know-how we have cultivated with aluminum handrails, it can flexibly follow significant deformations of buildings due to earthquakes and has been confirmed through our own tests to withstand wind pressure from super typhoons, allowing you to use it with confidence.

Since its founding in 1970 (established in 1972), Tsuzuki has expanded its business from product development as a manufacturer of aluminum interior and exterior building materials, primarily for buildings, to a one-stop service that encompasses manufacturing, sales, design, and construction. The aluminum building materials produced include handrails, decorative panels, canopies, and louvers, which beautifully adorn urban structures. In addition to the "aluminum building materials business," the company is also advancing initiatives in the "external insulation business" and the "renovation and renewal business for apartments and buildings." To respond to the changing needs of the times, Tsuzuki underwent an internal company split in February 2021, establishing a composite building materials company responsible for new and derivative businesses related to aluminum building materials, including the external insulation wall business, which is part of its CO2 reduction efforts. The company is also pursuing corporate growth and social contribution through composite building materials businesses that combine previously incompatible construction materials, such as aluminum and tiles, offering a different approach from the aluminum building materials business. As a company that can contribute to various fields of society, Tsuzuki Co., Ltd. will continue to challenge new possibilities.
