Stay Comfy All Summer With These Affordable Sun Blocking Window Tricks

The summer sun shining brightly through your windows can quickly make rooms unbearably hot. Installing expensive blackout shades or replacing all your windows with tinted glass may not be affordable options for many homeowners. Fortunately, there are clever and budget-friendly ways to block sunlight and reduce heat coming through your existing windows to keep your home comfortably cool.

With a little creativity and some simple, inexpensive materials, you can transform sun-drenched rooms into cool sanctuaries. Read on to learn handy tricks for blocking sunlight and saving energy this summer without breaking the bank.

Use Window Film to Reflect Heat

One of the quickest and cheapest ways to protect your home from intense sun exposure is by applying window film. These thin plastic sheets come in tinted, reflective, and even opaque varieties. They easily stick to window glass using self-adhesive backing. Window films work by reflecting UV rays and preventing heat from entering your home.

Compared to replacing windows or installing shades, DIY window film kits cost a fraction of the price. Films are also temporary and removable, making them a smart choice for renters. Reflective metallic or mirrored films offer the maximum sunlight and heat protection. For sheer privacy without total light blocking, consider tinted or frosted options.

Different Types of Window Films

Here are some common types of window films and their key benefits:

• UV protection film blocks 99% of ultraviolet rays to prevent fading of interiors.
• Reflective films excel at rejecting solar heat gain from sun exposure.
• Blackout films completely block light for darkening rooms.
• Decorative films come in colored or patterned options for added privacy.

Tips for DIY Installation

Installing window film is an easy weekend project. Follow these tips for a smooth application:

• Clean window glass thoroughly before applying film.
• Spray glass and film lightly with application fluid for easy positioning.
• Carefully remove air bubbles and wrinkles for an invisible look.
• Use a plastic smoother to adhere film tightly to glass.
• Trim excess film around edges with a sharp utility knife.

Reflect Sunlight with Window Coverings

Installing reflective window shades or curtains is another inexpensive trick for blocking sunlight. The metallic materials work by bouncing the sun's rays away from the window rather than absorbing heat. Here are some creative ideas:

• Hang aluminum foil or emergency blankets behind existing curtains.
• Buy ready-made reflective curtains or curtain liners.
• Install reflective blinds with white backing to maximize solar reflection.
• Make DIY curtain panels from reflective car windshield sunshades.

You can find reflective window treatments in many styles to suit your home's decor. Adjustable blinds offer flexibility, while blackout curtains provide maximum light blocking for nighttime darkness. Close them fully during the brightest part of the day to prevent heat and glare from sun-exposed windows.

Create Do-It-Yourself Reflective Shades

With some basic crafting skills, you can even make your own reflective window shades:

• Use foil-coated cardboard or insulation sheathing for a sturdy material.
• Glue reflective mylar or metallic origami paper to cardboard or foam panels.
• Cut corrugated plastic sheets to size and attach ties or grommets.
• Wrap foam pipe insulation in aluminum foil and adhere reflective tape.

Install your custom reflective shades in windows using tension rods, or use adhesive velcro dots to attach them directly to window frames. Get creative with materials - anything that creates a reflective barrier can help block sunlight!

Install Exterior Shades for Outdoor Sun Control

Exterior window shades are installed outside your home to block sunlight before it hits the glass. They are excellent at preventing solar heat gain during summer. Compared to interior shades, exterior shades also allow you to keep your view while blocking glare and UV rays.

Prefabricated exterior shades can be pricey, but you can create your own with a little DIY effort. Here's how to make budget-friendly exterior sun screens:

• Use sheets of corrugated plastic, metal, wood, or heavy cardboard.
• Cut panels several inches wider than your window opening.
• Mount them above windows at an outward angled slope.
• Space panels at least 2 inches from house to allow airflow.

Hardware stores carry durable corrugated plastic sheeting that holds up to weather and wind when installed properly. For a transparent filtered light effect, try using corrugated fiberglass or polycarbonate roofing panels.

Maximize Efficiency of Exterior Shades

Follow these tips to get the most performance from outdoor shades:

• Angle shades at 45-60 degrees for optimal solar protection.
• Install shades on north, east, and west-facing windows to control morning/afternoon sun.
• Use adjustable shades to tweak sunlight blocking as needed.
• Allow a gap for ventilation to prevent moisture buildup.

Insert Window Frames for an Insulating Barrier

• Use insulating materials like acrylic, polycarbonate, foam boards, or double pane glass.
• Line edges with adhesive weatherseals for an airtight seal.
• Add reflective facings like mylar or aluminum foil to reflect heat.
• Install securely with screws, magnets, or tape on window stops.

Benefits of Window Inserts

• Reduces conducted heat loss in winter and heat gain in summer.
• Lowers energy bills by up to 25% for better efficiency.
• Helps block external noise and improves indoor acoustics.
• Can be used in any window type for added insulation.

Use Household Items for Short-Term Sun Blocking

• Apply reflective car windshield shades on windows.
• Use contact paper, laminate sheets, or aluminum foil to cover glass.
• Cut cardboard sheets to block out sunlight.
• Hang lightweight curtains or bedsheets for sheer screening.

• Affix plywood panels or rigid foam boards to window frames.
• Arrange indoor plants on windowsills to filter incoming light.
• Apply window screen mesh behind curtains for an extra layer.
• Use wooden slat blinds from old shipping crates or pallets.

Balancing sunlight blocking with openness and views can require some trial and error. Here are a few final pointers for keeping your home comfortably cool this summer without spending a fortune:

• Prioritize sun-exposed rooms like south and west-facing spaces.
• Match solutions to window size, room use, and optimal lighting needs.
• Stick with temporary options if needs change seasonally.
• Supplement window treatments with fans, roof overhangs and shade trees.
• Verify your homeowner's rules before installing exterior shades.
