In 2024, I had loose curtains haning on windows with flowery patterns for a pleasant aesthetic \u2013 they did the job! My summer electricity expenditure was $239 for June through September 2024, with air conditioners working in three rooms \u2013 one living room and two bedrooms. When I heard that the power bills were projected to go even higher in 2025, I was alarmed and started looking for ways to minimize cooling costs. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">An article on New York Times, titled \u201c<\/span><a href=\"https:\/\/www.nytimes.com\/2022\/07\/22\/business\/air-conditioner-electricity-bill.html\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">How to Lower Your Summer Electric Bill<\/span><\/a><span style=\"font-weight: 400;\">\u201d suggested \u201cClose shades or blinds during the day\u201d. But that wasn\u2019t of much help the previous 2024 summer. I consulted my next-door neighbor Kristin, who recommended using double cellular shades. I acted upon her advice and the result was marvelous! My summer electricity bill was $160 (down from $239), saving me flat $79 a single cooling season and the comfort was in addition!\u201d<\/span><\/p>\n<h3>2. 1% Openness Solar Shades \u2013 Natural Light &amp; Privacy While Reducing the Heat Gained<\/h3>\n<figure id=\"attachment_8762\" aria-describedby=\"caption-attachment-8762\" style=\"width: 650px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/affordableblinds.com\/blog\/wp-content\/uploads\/2023\/05\/Openness-comparison-.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-8762\" src=\"https:\/\/affordableblinds.com\/blog\/wp-content\/uploads\/2023\/05\/Openness-comparison-.jpg\" alt=\"Solar Shades Openness comparison\" width=\"650\" height=\"550\" srcset=\"https:\/\/affordableblinds.com\/blog\/wp-content\/uploads\/2023\/05\/Openness-comparison-.jpg 650w, https:\/\/affordableblinds.com\/blog\/wp-content\/uploads\/2023\/05\/Openness-comparison--300x254.jpg 300w, https:\/\/affordableblinds.com\/blog\/wp-content\/uploads\/2023\/05\/Openness-comparison--70x60.jpg 70w\" sizes=\"auto, (max-width: 650px) 100vw, 650px\" \/><\/a><figcaption id=\"caption-attachment-8762\" class=\"wp-caption-text\">Solar Shades Openness comparison<\/figcaption><\/figure>\n<h4>Pros<\/h4>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">1% open are the best solar shades for blocking heat<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Block 99% of solar heat waves and UV rays that strike the window panes<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Protect your furniture from sun damage<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Can be used as outdoor heat blocking shades for decks, pergolas, and <\/span><a href=\"https:\/\/affordableblinds.com\/blog\/what-to-consider-when-choosing-sunroom-blinds\/?srsltid=AfmBOopzrDWDNMtC6RNCKdMmpX153gWDc8_CPagX1aAoXFFTOGlJepAI\"><span style=\"font-weight: 400;\">sunrooms<\/span><\/a><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Available with an opaque liner for total blackout effect in your bedroom<\/span><\/li>\n<li aria-level=\"1\">Fabric weight (GSM or Denier) also plays a role in the shade&#8217;s durability and effectiveness.<\/li>\n<\/ul>\n<h4>Cons<\/h4>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Partial nighttime privacy<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Less energy efficient compared to thick cellular shades<\/span><\/li>\n<\/ul>\n<h5>Pro Tip<\/h5>\n<p><span style=\"font-weight: 400;\">If you are using solar shades as winter window coverings, you\u2019ll most probably want them to let in most of the sun, only blocking out the UV-component. In that case, we recommend higher openness factors, such as 3%, 5%, or 7%. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">But do not exceed 7%, as it will impact their capability to filter harsh light and provide daytime privacy. Solar shades are not typically made for nighttime privacy. To block views from the outside at night, you\u2019ll always need a privacy or blackout liner.<\/span><\/p>\n<h3>3. Heat Reflective Window Films to Keep the Sun\u2019s Harsh Rays at Bay<\/h3>\n<p><span style=\"font-weight: 400;\">A high quality reflective window film can 100% block out the sun\u2019s rays and help maintain the temperature, cutting down on your home\u2019s cooling costs in summer.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are two types of heat blocking reflective films: sputtered and hybrid. Sputtered reflective films provide clear views of the sky while hybrid reflective films block both UV and solar heat.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Whether installed inside or outside the window frame, reflective window films provide the best heat and UV prevention. However, the reflective effect is reversed during the night. It is a very affordable option.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Before <\/span><a href=\"https:\/\/affordableblinds.com\/blog\/buying-guides\/\"><span style=\"font-weight: 400;\">buying the best reflective film for the windows<\/span><\/a><span style=\"font-weight: 400;\">, understand its properties. The SHC (Solar Heat Gain Coefficient), is an important measurement to consider. This measurement indicates how effective the film is at blocking UV and visible light.

But if you\u2019re looking for a classic look that can be customized to fit your own personal style, traditional fabric blinds are a great option.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Here are a few tips to help you choose the right window blinds and shades that block heat from windows.<\/span><\/p>\n<h3>1. Heat Blocking Capability<\/h3>\n<p><span style=\"font-weight: 400;\">First, consider the heat blocking potential of the blinds and shades. Do you want to partially or completely block out heat? Go with spectrally selective window film. It\u2019s important to consider how much heat you want to block before making a purchase.<\/span><\/p>\n<h3>2. Location &amp; Direction of Windows<\/h3>\n<p><span style=\"font-weight: 400;\">The first thing to think about is the location and direction of the heat blocking windows. Are you windows south-facing? Are they on the wall or the roof? For windows more exposed to the sun, choose heat-resistant material.<\/span><\/p>\n<h3>3. Size<\/h3>\n<figure id=\"attachment_8251\" aria-describedby=\"caption-attachment-8251\" style=\"width: 650px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/affordableblinds.com\/blog\/wp-content\/uploads\/2023\/01\/measure.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-8251\" src=\"https:\/\/affordableblinds.com\/blog\/wp-content\/uploads\/2023\/01\/measure.jpg\" alt=\"Window Measurement\" width=\"650\" height=\"550\" srcset=\"https:\/\/affordableblinds.com\/blog\/wp-content\/uploads\/2023\/01\/measure.jpg 650w, https:\/\/affordableblinds.com\/blog\/wp-content\/uploads\/2023\/01\/measure-300x254.jpg 300w, https:\/\/affordableblinds.com\/blog\/wp-content\/uploads\/2023\/01\/measure-70x60.jpg 70w\" sizes=\"auto, (max-width: 650px) 100vw, 650px\" \/><\/a><figcaption id=\"caption-attachment-8251\" class=\"wp-caption-text\">Window Measurement<\/figcaption><\/figure>\n<p><span style=\"font-weight: 400;\">Another important factor is the size of the blinds or shades to block heat from windows. Make sure that they are wide enough to cover the entire window, but not so wide that they block out too much light. For this, you\u2019ll need to <\/span><a href=\"https:\/\/affordableblinds.com\/r\/how-to-measure\/\"><span style=\"font-weight: 400;\">take accurate measurements<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<h3>4. Material<\/h3>\n<p><span style=\"font-weight: 400;\">Finally, pay attention to the material of the energy efficient window treatments. Light-colored fabrics will reflect more heat and prevent it from coming into your <\/span><a href=\"https:\/\/affordableblinds.com\/rooms\"><span style=\"font-weight: 400;\">room<\/span><\/a><span style=\"font-weight: 400;\">, while dark-colored fabrics will absorb more heat.\u00a0<\/span><\/p>\n<h3>5. Style<\/h3>\n<p><span style=\"font-weight: 400;\">Next, consider <\/span><a href=\"https:\/\/affordableblinds.com\/category-by-style-of-shade\"><span style=\"font-weight: 400;\">the style of your home<\/span><\/a><span style=\"font-weight: 400;\">. Are your <\/span><a href=\"https:\/\/affordableblinds.com\/blog\/window-treatments-for-large-windows\/\"><span style=\"font-weight: 400;\">windows large<\/span><\/a><span style=\"font-weight: 400;\"> or small? Are they traditional or modern? There are blinds available in a variety of styles to match any aesthetic.<\/span><\/p>\n<h3>6. Child Safety and Legal Compliance<\/h3>\n<p><span style=\"font-weight: 400;\">Whether it is indoor or outdoor space, when 8 year old or younger children are around, their safety must be your top priority. So, always <\/span><span style=\"font-weight: 400;\">choose a pet- and child-safe, <\/span><a href=\"https:\/\/www.cpsc.gov\/gocordless\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">CPSC-approved<\/span><\/a><span style=\"font-weight: 400;\"> option that 100% conform with the New <\/span><a href=\"https:\/\/www.federalregister.gov\/documents\/2022\/11\/28\/2022-25041\/safety-standard-for-operating-cords-on-custom-window-coverings\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">US Federal regulations<\/span><\/a><span style=\"font-weight: 400;\">.

Budget<\/h3>\n<p><span style=\"font-weight: 400;\">Finally, think about your budget. Heat blocking blinds and shades can range in price from as low as $18 to as high as $1000+ depending on the <\/span><a href=\"https:\/\/affordableblinds.com\/blog\/the-benefits-of-each-type-of-window-blinds-material\/\"><span style=\"font-weight: 400;\">material<\/span><\/a><span style=\"font-weight: 400;\">, style, <\/span><a href=\"https:\/\/affordableblinds.com\/blog\/do-blinds-come-in-standard-sizes-find-out-here\/\"><span style=\"font-weight: 400;\">size<\/span><\/a><span style=\"font-weight: 400;\">, and lift option, so it\u2019s important to set a budget before beginning your research.
