Reflective breather membrane for improved thermal comfort throughout the year
New Tyvek® e-Guard W1 reflective breather membrane Reflecting radiant heat in summer and reducing convective heat loss in winter.
The airtight and water resistant yet vapour-open reflective breather membrane provides a secondary protection from external moisture.
Durable, but flexible and easy to install Tyvek® e-Guard W1 is particularly effective in lightweight wall construction such as timber frame systems.
Its outstanding properties:
Excellent long-term performance (based on tried and proven technology from DuPont™ Tyvek®)
4 months UV resistance prior to covering
Robust: unique 175 microns functional layer
• PROTECTION FROM WATER:
Water resistance (W1); 1700 mm water column helps protect against water damage, wood rot…
• ENHANCED AIRTIGHTNESS
Wind tight but vapour open
Vapour resistance 0,25 MNs/g
• COMFORT AND ENERGY SAVING
Reflects 97% of heat radiation (emissivity 3%) for improved thermal comfort throughout the year
• THERMAL RESISTANCE
Thermal resistance value for all vertical cavities larger than 20 mm: 0,75 m2K/W (NPL guarded hotbox method)
