The trick is to use the right type of window shades to block the heat and to install them as close to the glass as possible to get the maximum benefit. For insulation purposes, cellular or honeycomb shades are the most effective. The honeycomb shape helps to trap air, reducing your solar heat gain.
Materials with a low thermal conductivity like cardboard are perfect for making insulation. These are used to keep heat from transferring between objects or locations. A good example of this is when faced with a window being broken and left without replacements on hand.
How do windows lose heat? Radiation through glazing occurs is when the inner panes of glass absorb the heat generated from the internally is transmitted to the cooler outside pane via conduction. Convection inside the glazing cavity can cause heat loss when air within the cavity is warmed by the inner pane.
Aerogel is more expensive, but definitely the best type of insulation. Fiberglass is cheap, but requires careful handling. Mineral wool is effective, but not fire resistant. Cellulose is fire resistant, eco-friendly, and effective, but hard to apply.
In warmer months, three-quarters of the sunlight that shines through standard, double-pane windows enters the house to become heat. Adding window treatments, fixing broken and leaky windows, and choosing new, Low-E glass window panes designed to reduce heat gain can keep you comfortable with less wasted power.
Spreading tin foil on any windows that receive direct sunlight can redirect the sun and heat away from your home. While it may introduce a somewhat space-age aesthetic to your household, it's a cheap and temporary fix to the problem of extreme heat.
Expanded polystyrene can be a budget-friendly option that offers good thermal- and sound-insulating properties.
Block the heat
Shade windows and walls using external coverings, like blinds, awnings or large potted plants. Plant deciduous trees that cast shade over your home in summer, but still let the sun shine through in winter.
The amount of decibels that escaped the box were measured by a decibel reader. Results: Acoustic foam insulated the most sound with an average of 19 decibels blocked. The remaining materials, from least to greatest decibels insulated, were cardboard, cotton, and secondly styrofoam.
Why does household aluminium foil have one dull side and one shiny side? SO THAT the shiny side can reflect the heat on to the item to be cooked, using a long-established scientific principle that shiny surfaces reflect heat and light.
Insulation. Simply put, this is the best way to cool down a house with big windows. While insulation may be only one word, it needs to be applied in multiple places (and in multiple ways) in order to really be effective in making a home like Jeff's more comfortable so he can enjoy those gorgeous Folsom views.
An insulating window film applied over a window can help the window retain up to 55 percent more heat in winter, potentially reducing your heating costs up to 30 percent. These films are less effective at reducing summer heat gain, though.
The Best Window Insulation

The Pros of Aluminum Foil on Windows
If you choose this method, it can be a cheap and effective way to keep your house cool. Foil can block up to 95% of the sun's rays and reduce heat gain inside your home. It can also provide privacy and prevent unwanted light from entering your rooms.
“It'll absorb some and some will get inside, but then most of that will be reflected.” Dr. Bhandari said the aluminum foil might transfer some heat through the window as the aluminum itself gets hotter and through a process called conduction could then heat up the glass.
During the hotter months, window film provides a barrier between the outdoor heat and the inside of your home, so the cool air remains inside, and your AC unit won't have to work as hard. This can help reduce energy costs in the summer while ensuring your environment is cool and comfortable.
The short answer is yes – blackout blinds block sunlight, making them one of the best ways to keep a room cool. Keep your blinds closed all day and you'll find there's a noticeable difference in room temperature – and the more sunlight your blinds block out, the cooler the room will be.
Blackout window film will completely block out the visible light spectrum. It won't, however, solve your summer overheating issues.
