Characteristics of Low-E Insulation technology (Certification: Green Technology Certification - GT-12-00092, Ministry of Land, Infrastructure and Transport)

Characteristics of Low-E Insulation technology
Category Low-E Insulation Technology Other Insulation
(Glass wool, EPS, XPS)Technology
Advantages of Low-E Insulation technology
Surface properties Low Emissivity High Emissivity 1/8th of the reduction effect of incident and emission heat
Internal
properties
Heat transfer method Radiant Heat Conductive Heat Low-e is changes the internal heat transfer mechanism
from radiant heat to conductive heat
Internal Air Layer Yes None Build effective structure for radiant heat shut-off
Characteristics of
Internal structure
Structure to block Radiant heat None, Massive insulation
Heat transfer 2% 4-5% Double the effect of reducing compared to
100% of general building materials
