11 Ways to Block Sun Heat from Windows

Numerous solutions exist to block heat from windows. The effectiveness of these methods varies; some may need more aesthetic appeal. 

By comprehensively exploring and contrasting your alternatives—considering block-out blinds, experimenting with bubble wrap, or exploring advanced window solutions—you’ll gain a thorough understanding of the implications and outcomes associated with each attempt to shield your home from the oppressive heat of sunlight.

Heat Blocking Window Shades

Window shades offer a simple DIY way to combat heat gain, especially with lighter colors that reflect sunlight. Choose shades that block heat well and mount them close to the window for best results. Consider drapes for aesthetics, but weigh the cost.

This version keeps the critical points about window shades being a DIY solution for reducing heat gain, emphasizes the importance of color and positioning, and mentions drapes as an option while acknowledging the potential cost. It’s concise and informative while retaining the essential information.

Panel Blind

Blackout blinds block light and sun, offering some heat protection. They work best placed close to windows and reflect heat well. However, their true strength lies in darkness, not cooling power. Choose them for light control, but expect less heat reduction than proper heat-blocking options.

External Window Shades

Create shade outside your window by strategically placing plants or installing awnings. DIY is an option, but professional help may be needed for optimal results. Plants cool the air by releasing water vapor, contributing to a cooler exterior. Awnings or eaves reduce direct sunlight, and consulting a professional ensures proper positioning for the best shading results.

Bubble Wrap

Bubble Wrap

Bubble wrap proves to be an unexpectedly effective heat insulator. The miniature air pockets within the material act as insulating barriers, preventing heat transfer. While it may not enhance the visual appeal, its ability to reduce heat transfer by up to 50% is remarkable.

What sets bubble wrap apart from aluminum foil is its capacity to allow light to filter through. It comes at no cost, making it a cost-effective solution that provides winter insulation. All in all, it stands out as possibly the most economical method to block heat from windows without spending a dime.

Heat Reducing Window Film

Have you considered employing a specialized heat-reducing plastic film?

You can buy a dedicated insulating plastic film designed for windows. Affixing it to the interior side of your glass establishes a small air gap, akin to the effect of plastic bubble wrap. While the impact may not be dramatic, covering all your windows with this film can help impede some heat infiltration while allowing you to bask in the benefits of natural light.

Cellular Shades

Cellular shades are a stylish and energy-efficient choice for window coverings. Constructed with pleated layers forming a honeycomb pattern, they reduce heat transfer by blocking up to 60% of the sun’s heat energy. Unlike permanent window films, cellular shades can be easily opened or closed, providing flexibility. In the winter, they can be rolled up to welcome solar heat, making them an excellent option for seasonal window insulation.

Upgrading to Energy Efficient Window

Upgrading to Energy Efficient Window

Recent advancements in window engineering offer significant gains in energy efficiency, potentially offsetting costs through reduced power bills. Prioritize checking the light-to-solar gain (LSG) rating before purchasing, as it indicates how well different glass types balance daylight transmission and heat blocking. Additionally, explore various energy-efficient window options, comparing performance ratings, to address heat prevention in windows effectively.

Weatherstripping on Windows

Applying weatherstripping around your windows is one of the quickest, easiest, and most cost-effective solutions to insulating windows and preventing heat from entering. Windows often have gaps that are common points for air leaks in homes.

Weatherstripping stands out as an excellent method for insulating windows during the summer. It is essential to explore various weatherstripping types to ensure you select the most suitable option for each window type.

Hanging Blankets

Consider hanging blankets over your windows and doors for a quick and temporary fix. Opt for quilted fabric as it works best due to its multiple layers that effectively trap heat. The challenge lies in keeping it securely in place, but you have various options, such as using a curtain rail, tapes, or hooks.

Planting Shade Trees

Carefully positioning shade trees around your residence can notably diminish the heat reaching your windows. Choose trees with lush foliage that offers substantial shade, especially during the peak hours of heat. This organic method not only prevents the intrusion of sunlight but also elevates the visual charm of your property.

Aluminum Foil

Consider covering your windows with aluminum foil for a quick and budget-friendly solution. This reflective material efficiently blocks out light and is readily available.

Remember that it may not be aesthetically pleasing and could affect your neighbors, as the shiny foil may cause glare or increase nearby temperatures due to its reflective nature.

Conclusion

Keeping your home cool and comfortable is attainable through implementing these 11 effective strategies to block sun heat from windows. Whether you choose energy-efficient window coverings, reflective films, or strategic furniture arrangements, these solutions can markedly diminish the influence of sunlight, ensuring a pleasant and cool ambiance in your home during the hottest months.

FAQs

Is it better to have curtains or blinds?

Optimal for expansive rooms, full-length curtains impart an elegant touch, whereas blinds prove more fitting for compact spaces and moisture-prone areas like bathrooms and kitchens. It is worth noting that when furniture, such as a bed or sofa, is situated beneath the window, the preferable choice is window blinds.

Do I still need curtains if I have blinds?

Frequently, we encounter the question, “Can curtains and blinds be used together?” The response is generally affirmative – these two elements can create a versatile decor while effectively managing light and ensuring privacy. Nevertheless, adhering to specific style guidelines is essential to achieve aesthetic harmony.

Why do curtains look cheap?

Opting for curtains that are too short may give a room an incomplete and inexpensive look. It is also advisable to enhance the fullness of your window coverings by incorporating additional fabric. You can achieve this by doubling the curtain panels’ width or using multiple panels on each side of the window.
