That external Venetians are more effective in reducing heat energy or cooling loads in comparison with internal blinds is backed by research.
Evaya offers the ev80 and ev93D external Venetian blinds, which deliver a multitude of benefits to ensure comfort and convenience. These blinds are adjustable so as to:
- Exclude solar radiation, depending on the sun's position
- Reflect light internally without letting heat in
- Manage natural light without the glare
- Maximise solar heat gain during winter
- Allow direct view whilst providing a high degree of privacy
The ev80 and ev93D external Venetian blinds are made from aluminium, which has excellent properties that can offer low transmission values, absorption of solar heat as well as high solar radiation reflection. External Venetians are effective in reducing greenhouse gas and carbon dioxide emissions, household energy requirements and expenditure.
Internal shading devices require a larger investment in cooling systems to maintain a comfortable temperature, whereas external Venetians can prevent more than 85% of heat from entering rooms.
