Tyvek® Smart

Tyvek® Smart

"Winter is moisture-proof, summer is moisture-permeable." It is a special airtight sheet that maintains airtightness throughout the year while allowing permeability to change according to the humidity conditions within the wall.

■Winter moisture-proofing, summer moisture-permeability While ensuring airtightness (preventing air passage), this smart vapor barrier functions like a regular moisture-proof airtight sheet in winter by not allowing moisture to pass through, and in summer, when the interior of the wall becomes hot and humid, it allows moisture to pass through, maintaining a good condition inside the wall throughout the year. In summer, moisture tends to move towards the indoor side due to the temperature gradient, but if a regular moisture-proof airtight sheet (PE sheet) is installed, the humidity between the insulation and the PE sheet may become extremely high. Particularly, right after construction, the structural elements and moisture released from the foundation concrete are significant, leading to increased humidity inside the wall and further raising the risk.

VCL Smart

VCL Smart

By ensuring proper airtightness, we promote constant dryness by "moisture-proofing in winter" and "moisture-permeability in summer."

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.

Moisture-permeable, waterproof + airtight sheet "Rain Screen Wrap"

Moisture-permeable, waterproof + airtight sheet "Rain Screen Wrap"

Thanks to its high drainage capacity, it prevents rainwater from accumulating on insulation materials and wooden battens!

In pursuit of a better thermal environment for housing, initiatives such as "external insulation" and "double insulation" have increased. The "Rain Screen Wrap" is a breathable, waterproof, and airtight sheet that does not adhere the external insulation material or furring strips to the waterproof paper of the exterior wall, allowing rainwater that has entered to be smoothly drained without stagnation. This breathable, waterproof, and airtight sheet is particularly recommended for construction methods that apply coatings to EPS insulation materials. 【Features】 ■ It has drainage and moisture removal capabilities suitable for board-type insulation materials. It creates an average gap of 1mm between the external insulation and the breathable waterproof paper, efficiently (in a short time) and effectively (in large amounts) draining rainwater without stagnation. ■ Moisture that has permeated from inside the wall is also removed through this 1mm thick gap. ■ Protection of wooden furring strips. ■ Ant-proofing agent. It does not lose waterproofing even when in contact with treated structural panels, furring strips, etc. ■ Strength and durability. * For waterproofing around windows and piping, please use the dedicated waterproof tape "Hydro Flash Tape" for Rain Screen Wrap. * For more details, please download the PDF or feel free to contact us.
