The sun during summer is a welcomed change from the cold months, but it can turn our homes into unwelcome sweat boxes. A good amount of the heat makes its way indoors through the windows. Windows are made of glass and might look harmless, but they are the reason for intense heat buildup in the room which increases air conditioning costs. Knowing how to solar heat control windows economically is necessary for comfort and energy efficiency in the house. This wonderful guide includes a range of do-it-yourself projects, sophisticated technology, and more so you can stay cool without overspending. this is not just about affordable solutions, but rather how to improve the environment of the house. Creating a cooler indoors climate during summer is what we will empower homeowners to do through efficient comparison options, practical window treatments, and the necessary science.
Why Your Windows Make Rooms Hotter
The processes responsible for the rooms being warm when the sunlight comes streaming through the windows is primarily caused by what is defined as Solar Heat Gain (SHG). Solar heat is a mixture of different types of radiation including light, ultraviolet (UV) radiation, and infrared (IR) radiation. The most important type of radiation for heat energy is infrared radiation. The glass windows also have some portion that is absorbed as well as reflection, a large amount is transmitted directly.
The energy of the transmitted sunlight is absorbed by the floors, furniture, and walls as sunlight is refracted into the area. Later, this energy is transformed into longer wavelength infrared heat; which is radiated back out. The re-radiated heat also contains infrared radiated heat which is difficult to pass back through the glass. As a result, this heat is trapped inside. Additionally, glass is not an effective insulator. On a hot day, the exterior pane heats up to above average temperatures, glass material transfers the heat into the cooler interior space, and then radiates it. Though double or triple glazing slows this process, it doesn’t eliminate it completely. The type of window used coupled with single paned ones are the most vulnerable. Learning the reasons these inefficiencies take place is the first step towards effectively controlling heat gain block challenges.
Quick & Ultra-Cheap DIY Heat Blocking Hacks
In certain moments when the budget is tight and relief is needed immediately, creativity comes to the rescue and offers a variety of options. Below are some steps that can greatly reduce heat at a low cost, yet come with trade-offs in aesthetics or permanence.
Bubble wrap is one of the most commonly used materials which assist and aid in window insulation. Infact, plastic bubble wrap can shield windows. The only steps needed to achieve this wrap bubble window insulation is to spray the window glass’s surface lightly with water and press the flat side of it towards the pane. The bubbles within this wrap are able to act as an insulating layer that maintains the temperature within the desired place. Even though it is relatively cheap, it is moderately effective and increases the cost significantly.
Aluminum foil is one material that can still be adjusted and used in a better way. Taping the shiny face of the foil facing outside can help in reflecting the solar heat a room receives. As strong as that tactic is, it’s not the be all and end all. it also forbids daylight from coming through, forcing everyone inside the room to use alternative light sources. In addition to that, it alters the view from the outside making it less appealing. It offers the best results as a temporary solution.
Finally, situated within the mount are flat pieces of simple cardboard that can act as a passen opaque partitions to the window frame. It absorbs some heat and cuts light out entirely. Just as foil does, It prevents the view from being seen, making it likely for unused rooms. Although these methods provide relief straight away, they need compromises. These methods provide insulation but lack craftsmanship.
Affordable Window Coverings That Work
Moving away from the improvised, there are a few widely available options that are aesthetically more graceful than do it yourself solar heat gain window coverings. These, however, do require some investment because of the enhanced material usage and visual integration with the environment.
Blackout Curtains & Thermal Curtains (Drapes)
Blackout curtains and specially designed Heavy Drapes or Blackout Blinds are quite popular and extremely useful as well. While mostly used to obstruct daylight, blackout curtains also block a reasonable amount of heat due to their thick fabric. Thermal curtains or window quilts take it to another level. They usually have multiple layers of materials offering good insulation. These draperies form a solid barrier to sunlight heat from coming in. The thermal lining will assist in restraining air flow which hinders heat transfer. Some of these also come with reflective backing which helps send solar heat back outside.
- Effectiveness: Having the right quality thermal curtains will ensure maximum heat gain emanation especially if they are positioned very close to the window.
- Cost: Functional provisions are quite reasonable, being an inexpensive and decorative addition.
Blinds (Venetian, Vertical, Cellular)
Installing window blinds can significantly aid in controlling light capture, as well as for purposes of capturing and minimizing heat. Various forms of traditional blinds such as Venetian and vertical blinds utilize slats that can be adjusted. Correctly angling the slats upwards can assist in deflecting direct sunlight towards the ceiling which reduces glare. Lighter shades, or reflective shades, can also minimize heat during summers as they reflect a larger portion of the sun. Insulating cellular shades (or honeycomb shades) do exist for these purposes. These shades feature pockets shaped as honeycombs which are great for trapping and blocking air.
- Effectiveness: While standard blinds are able to block moderate levels of heat, cellular shades do a better job at insulating and minimising heat capture.
- Cost: Basic blinds are relatively cheaper, while energy efficient cellular shades are more expensive.
Basic Solar or Reflective Window Film
Another effective approach is applying a plastic film directly on the glass of the window. Various basic solar control window film products do exist which reflect or absorb a large portion of solar radiation before passing through the glass, resulting in a greatly diminished amount of solar energy entering the premises.
- Effectiveness: DIY window film can greatly assist in minimizing the glare and UV rays while keeping homes relatively cooler.
- Cost: Maintenance of a good view, albeit tinted, can be achieved with Do It Yourself kits, which in turn makes it seem relatively inexpensive.

Pro Tips for Maximum Heat Reduction
Extra methods can be applied to improve additional strategies that will allow the heat coming through windows to be blocked. Here’s a look at these tactics.
Use blinds and curtains that fit the window as closely as possible. This strategy improves heat convection. Wraparound rods serve as curtain tracks and allow them to be closed off at the sides, therefore giving side tracks for shades. Window shades and blinds should always be closed before direct sunlight comes in contact with the glass.
Having windows shaded using external shading like window awnings or solar screens is quite beneficial. Solar screens block the sun from reaching the window. Solar screens block the sun from reaching the window. Awnings and overhangs serve as overhangs and also block the sun from reaching the window. Windows that are exposed to the sun will benefit from the existence of storm shutters. Strategically placed trees also serve as natural trees which offer shade.
Investing in good quality weather stripping for windows holds the hot air and other climatic conditions inside the house. During the day, the windows offer blockage of the sun which ensures good ventilation. Good padded storm windows are beneficial for long-term ventilation. By following these strategies they are a proven and reliable method of keeping the home cooler.
Long-Term Benefits: Savings and Comfort
Blocking window heat contributes positively towards comfort and finances, going beyond just relief from a high temperature.
For businesses and homes, architectural window film has shown optimal outcomes. Effective treatments reduce the heating of windows which lessens the workload for air conditioning and consequently helps in lowering the energy bill. In winter, some insulating methods can slightly reduce energy needed for heating as well.
Reduced energy costs help in blocking window heat, but cost is not a concern for everyone. Enhanced comfort is achieved indoors as well. Hot spots are reduced, therefore dramatically improving the living space.
Blocking UV rays is important and helps in protecting furnishings and fading interiors. Architectural film aids in blocking over 99% of UV rays which helps achieve this goal. Moreover, for top tier installations, there can be modest improvement in the property valuation due to the aid of comfort and energy efficiency. With these benefits, increased home value makes heat blocking an avid necessity.
