Ever Corporation's "Air Gap Sheet" is a ventilation and waterproof underlayment material for metal roofs that realizes the longevity of roofs. By creating a 10mm air layer between the roofing material and the sheathing, it efficiently expels moisture and heat, preventing condensation and improving durability. Additionally, it effectively reduces heat in the attic during summer and minimizes the impact of radiative cooling in winter, enhancing insulation performance. We are currently offering samples for free! Please feel free to contact us. 【Features】 - Reduces the unpleasant sound of rain on metal roofs! Soundproofing effect - Made of polypropylene that withstands high temperatures and humidity - The three-dimensional mesh structure excels in surface pressure resistance, with minimal deformation under load - Lightweight and easy to install, available in rolls of 15m - Easily cut with scissors or a cutter *For more details, please download the catalog or contact us.

Japan, with its many active volcanoes, often faces sudden eruptions. Even when people take refuge in mountain huts, there are still cases of injuries or fatalities caused by volcanic rocks raining down through the roofs. Urgent measures are needed. The locations of mountain huts are at high altitudes, making it difficult to bring in heavy machinery. Additionally, reinforcing the roofs with steel or concrete requires strengthening the structure to bear the added weight. Currently, attention is being drawn to the very durable para-aramid fibers used in cut-resistant gloves. These fibers can withstand volcanic rocks flying at speeds of 300 km/h and are being used for roof reinforcement sheets in mountain huts. When extensively reinforcing structures with steel or concrete, heavy machinery must be transported, and long construction periods are required. In contrast, aramid fiber sheets are lightweight, making them easy to carry by hand. Moreover, only the roofs need to be worked on, allowing for short construction periods and low-cost reinforcement. No special technology is required, making it easy for regular roofing contractors to install these sheets. *1: Para-aramid fibers: Among aramid fibers, they are particularly known for their strength, bullet resistance, and cut resistance, with products such as Technora, Twaron, and Kevlar available.

Traditionally, airtight sheets aimed primarily at preventing winter condensation, especially in cold regions, commonly used polyethylene film that "constantly prevents moisture." Recently, to enhance energy efficiency, there has been an increase in the installation of airtight sheets even in warm regions. However, in wooden houses in warm areas, there is a risk of reverse condensation in summer and mold growth due to structural dampness, leading to the belief that it is better to allow moisture permeability under high-temperature and high-humidity conditions. Against this backdrop, DuPont has been selling a variable moisture-permeable airtight sheet called "Tyvek Smart," which prevents moisture in winter and allows moisture permeability in summer. In Europe, such airtight sheets are referred to as "smart vapor barriers," and their adoption has been accelerating in recent years. Considering the anticipated global increase in demand, we have developed a new product to establish a more stable supply system. Its translucent nature is expected to improve workability and simplify inspections.

• Waterproof sheet

Tyvek Flashing Sheet This is a next-generation flashing sheet that reduces water leakage and condensation damage with approximately twice the waterproofing of Tyvek Housewrap and the industry's first moisture-permeable function. It has excellent strength and durability while being about 1/8 the weight of conventional flashing sheets. It is easy to bend at corners and is a product with excellent workability. Stretch Guard Easy one-step installation with no pinholes This is a stretchable waterproof tape made by combining crinkled Tyvek and butyl rubber. It is strong and highly durable, conforming to various areas with just one piece, making installation simple and speedy. Features - Moisture-permeable and waterproof performance (approximately twice the waterproofing of Tyvek Housewrap) - 1/8 the weight of conventional flashing sheets (compared to asphalt 940) - Easy to bend and high conformity at corners
