To reduce heat loss, draperies should be hung as close to windows as possible and fall onto a windowsill or floor. For maximum effectiveness, install a cornice at the top of a drapery or place the drapery against the ceiling. Then seal the drapery at both sides and overlap it in the center.
Large west, east and north-facing windows should be shaded for increased energy efficiency. External shading is much more effective at keeping your home cool than internal blinds or curtains, as it stops the heat reaching the glass, but using both external and internal window coverings will provide maximum protection.
Curtains, sealed blinds and shutters
Curtains lined with a layer of heavy material can reduce heat loss from a room through the window at night and cut draughts. Hollow blinds, fitted into place with a sealed frame, and sealed shutters will also help cut draughts and keep your heat in for longer.
Install Draft Stoppers: Place draft stoppers or door snakes at the bottom of windows to block cold air from entering. Seal Cracks and Gaps: Use caulk to fill in any cracks or gaps around window frames, especially if you notice air leaks. Apply Reflective Window Film: Consider applying reflective film to the glass.
Cold air coming through windows can be normal. However, we expect windows to seal properly. Meaning, they should seal without any gaps or openings.

Smart Home Cooling Tips. Close your blinds and curtains. Keeping your blinds closed during the day will reflect a surprising amount of heat radiating in through windows, especially during the time of day when the sun's rays shine directly on your home.
Insulated cellular shades are typically considered to have the highest R-values of all window coverings. The air pockets in the honeycomb cross-sections act as insulators, increasing the R-value and reducing the conduction of heat through the window.
Because blinds require slats to function, heat can easily escape through the slats. Whereas, curtains don't require slats so heat is easily maintained. The thicker the curtain is the more insulated they are. However, in summer, blinds are better than curtains for energy efficiency.
Not only does the window film keep heat inside when it's cold outside, but it has the opposite effect during hot summer months. Insulating window film blocks out the sun's heat while keeping a room cool by retaining the air from cooling equipment in the room.
Glass is a poor insulator, which is why windows tend to be the main source of heat loss in any home. When temperatures are colder outside than inside, glass conducts the heat from inside the house to the outside where it quickly disperses.
An estimated 25% of all heat loss occurs through the attic or roof of a home. Cracks or holes in an attic, along with improperly placed vents, allow for significant amounts of heat loss through the attic space. In addition, improper ventilation in attics leads to even more heat escaping.
This can be achieved by the addition of thick curtains and a pelmet. A poorly fitted curtain allows heat loss to occur, while a well fitted curtain combined with a pelmet significantly reduces heat loss, so remember to: use closely woven, close fitting internal window coverings such as curtains or blinds.
q = (U × A) ×Δt
q = total heat loss through the building in Btu/hr, U = Overall coefficient of heat transmission through the building, A = the area in sq.
We'll break down each of these to give you a strong idea of what you should expect to pay. In general, you can expect to spend $5-$8 per square foot. However, luxury options like the 3M Prestige window film price will likely end up at $10-$12 per square foot.
To put it simply, yes. Reflective window film blocks a significant amount of heat, just like solar film.
Caulk around windows
One easy way you can stop an air leak around your window is by re-caulking it with a clear acrylic.
