Yes, they do! When completely lowered (with tightly closed slats) on a sunny window, highly reflective mini blinds can reduce heat gain up to 77%, according to the <\/span>Department of Energy<\/span><\/a> (DOE).<\/span><\/p>\n

What are mini blinds? They are <\/span>affordable blinds<\/span> made of horizontal slats that are less than half the width of standard (2-inch) <\/span>faux wood blinds<\/span><\/a>. They boost your <\/span>modern<\/span> decor <\/span>style<\/span><\/a> and are available with a <\/span>cordless<\/span><\/a> option, making them <\/span>safe<\/span><\/a> for home with kids and pets.<\/span><\/p>\n

These 1-inch-slat beauties can beat summer heat to keep you cool and cut your air conditioning costs.<\/span><\/p>\n

Mini-slat shades have dual thermal regulation functionality – they keep heat out during the summer and prevent heat loss during the winter.<\/span><\/p>\n

Plus you can stack their slats at the top to let the sun warm your room during the winter.<\/span><\/p>\n

If your windows are south-facing, the <\/span>solar<\/span><\/a> heat gain will be reduced by 65%. On the other hand, the \u2018minis\u2019 on west-facing windows beat the summer heat by 77%.<\/span><\/p>\n

For maximum heat prevention, use horizontal slats in light colors that reflect more sunlight. Research has shown that medium-colored <\/span>shades<\/span><\/a> with white plastic backings can reduce heat build-up by 33%. Switching to pure white color will further prevent harmful UV rays from entering your room, helping you cut down your air conditioning bills.<\/span><\/p>\n

Also, you can adjust their slats to control light and <\/span>privacy<\/span><\/a>, and to insulate. When you adjust the tilt of slats to reflect sunlight onto a light-colored ceiling, this phenomenon will diffuse light without much heat or glare. So, they would be a good choice for <\/span>home theaters<\/span><\/a>.<\/span><\/p>\n

Factors Affecting Ability of Mini Blinds to Reduce Temperature<\/b><\/h2>\n

If properly installed, your high-end <\/span>mini blinds<\/span><\/a> can reduce the amount of heat that gets into your house from the environment, creating a more comfortable living space.<\/span><\/p>\n

Following are the major factors affecting the <\/span>energy efficiency<\/span><\/a> of small-slat window coverings.<\/span><\/p>\n
