Both blinds and curtains increase the overall insulation of your windows to retain heat, which reduces your bills in winter. Because blinds require slats to function, heat can easily escape through the slats. Whereas, curtains don't require slats so heat is easily maintained.
Are blinds good insulation? Yes, blinds are good insulation for windows, regardless of the type of blind you use. This is because the closed blind forms a barrier (that is permeable to various extents depending on the blind), which helps to keep heat in, cold out, and to take the edge off draughts from rattly windows.
Yes, definitely. Fitting your blinds inside of the window recess rather than over it increases the extent to which they will keep warm air in and cold air out.
Sunshine streams in through the window, and the gap in between the window and blinds captures the heat, producing a greenhouse effect. In the winter, this is a desirable effect, and in the summer, when you want it to be cooler in your home, all you have to do is raise the blinds to leave the window uncovered.
In the cooler months, if you want to maintain a warmer temperature without letting in bright sunlight, it's best to close the blinds with the slats turned down. This would keep the rounded side of the blinds facing the room, helping direct the heat towards the center of the room to maintain a warmer temperature.
Window blinds are just as beneficial in winter. If snug against the window frame, they greatly reduce heat loss. They can also be kept open during the day and closed at night, trapping heat and reducing the need to turn on your furnace.
Window Insulation Film
Window insulation kits are a more affordable way to insulate multiple windows. Using heat control window film doesn't interfere with the look of your windows. Leaving up to 1-inch space from the window frame border, apply adhesive tape to the entire window.
Overall, white blinds can reasonably be considered to be better in terms of their ability to support an ambient temperature to some degree in both hot or cold weather; they're definitely better than black blinds in this respect if you look at the year-round picture.
Curtains will give better light control but blinds may be more practical in a smaller space. If you decide on a blind, have it made longer and wider than the window to minimise light drift. Curtains are best installed close to the ceiling or better still, with a pelmet above to stop light from escaping.
Honeycomb blinds are by far the most effective window treatment for heat retention. The unique construction of honeycomb blinds traps pockets of air to create an insulating barrier against cold windows. They're also fitted closely inside the window jamb, with only a minimal gap on the sides.
The simple fact is closing your curtains at dusk helps stop cold draughts from penetrating. And it helps keep the heat in your home. Even if you have double or triple glazing in your home and they are draught-proofed you can still lose heat through your windows. Therefore it's a good habit to fall into doing.
Each thermal curtain panel is made of 3 or 4 layers of materials. These thick, extra layers of fabric against your window create a thermal boundary between the outdoor air coming in through and the room itself. So the curtain traps the cold or hot air behind the fabric panels and keeps it from moving around your space.
One inexpensive way is by preventing cold air from coming in through gaps around your windows and sealing off any cracks with weather stripping and caulking. You can take that a step further by applying insulated window film and hanging thick, insulated curtains that can help protect against drafts.
Blinds can reduce heat gain by 45% for a significant increase in energy performance. Energy efficiency isn't the only consideration, though —curtains can offer better soundproofing than blinds, as well as add an elegant, luxurious feel to your home's décor.
Window blinds—vertical (Venetian blinds) or horizontal slat-type (louvered-type)—are effective at reducing summer heat gain and reducing glare, while providing good daylight indoors.
Absolutely. Curtains reduce the amount of air exchange between a cold window and the rest of the room. For keeping heat inside the home, high-quality curtains can reduce heat loss by around 40%, particularly if they are floor length and close to the wall and window panes.
Believe it or not, your blinds do have an insulating effect on your home. You probably don't think of that when buying them, but they do have energy-saving benefits because of their insulating property.
Around 10 per cent of the heat in our homes is lost through the window with that figure rising if you have single panes. It may not sound like that much but when you add up losses through doors, floors, walls and the roof every bit counts.
When you're trying to keep your home warm in winter, a draughty window can make your task quite difficult. Even if the window isn't actually damaged, having inadequate seals can be enough to let in enough cold air to affect the temperature inside.
