Thermal Curtains

What Are Thermal Curtains

According to studies, windows account for about one-third of all heat loss in a building, and a large portion of solar gain during hot months. Replacing and upgrading old windows is a good way to improve energy efficiency; however, it’s also costly and sometimes even impossible due to structural and code limits. While most opaque curtains help with temperature control up to a level, thermal curtains offer a sustainable and budget-friendly solution that makes a noticeable difference.

Thermal curtains are made from two to four layers of appropriate curtain fabrics, aiming to provide thermal resistance. Facing the room is the most decorative layer that can be made of any attractive material, including linen, wool, cotton, polyester, or even silk. 

The second layer is thermal resistant, and it’s either thick fabric or foam - or sometimes both. In the back, the third layer serves as a lining and protection, while the fourth one, when added, also makes a condensation vapour barrier. Backings in light hues also reflect sunlight, helping to reduce heat gain in the summer. Backings may be made of cotton but also from vinyl or other materials. 

Such construction forms a dead-air space between the room and the window, reducing heat and air transfer with a tight seal. That way, an insulating curtain keeps the warmth inside during the winter and reflects the sun rays during summer. 

Thermal Curtains VS Blackout Curtains

While all thermal curtains are, more or less, blackout types, not all blackout curtains boast thermal insulation qualities. 

Thermal curtains feature multi-layer construction, which insulates against both heat and cold, blocks light, and can even reduce sounds up to a certain level.

Blackout curtains block light with a single fabric layer that may feature a thin opaque lining, and make a better choice for rooms where insulation is not necessary.

Benefits of Thermal Curtains

Specific features and unique weave of curtain fabrics used for thermal and blackout curtains make them a convenient, sustainable solution. Due to solid insulating properties, thermal curtains help to reduce heating expenses and electricity spending.    

With the ability to fully block outside light, thermal curtains provide control over light levels and better temperature control in the room year-round.

Apart from allowing a more peaceful night’s sleep, thermal blackout curtains also support daytime activities, from afternoon rest to home cinema. 

Where to Use Insulated Curtain

While thermal curtains can be used in any room, home or office, some directions may help to maximise their utility. For instance, windows facing south and/or west tend to accumulate the most heat in the winter and need the most heat deflection during summer.

Thermal Bedroom Curtain 

Using full-length energy-efficient curtains in the bedroom is a good idea that promotes better nighttime rest. The blackout function will block the light flashes from outside, while the curtain construction will minimise the noise, and keep the room temperature at more comfortable levels.

Thermal Curtains in Dining Room

Thermal curtains add style and comfort to the dining room with their insulation qualities. Due to the variety of designs available, it’s possible to obtain thermal drapes that look quite elegant and luxurious while making mealtimes more pleasant. 

Kids Thermal Curtains

Kids thermal curtains are available in long and short versions, with appropriate design and patterns. Apart from insulation, they also provide a convenient atmosphere for afternoon napping time. 

How to Install Insulated Curtain

Thermal curtains need proper installation to be fully effective. Air-tightness affects the heat transfer, so the closer the thermal curtains are to the window frame, the better. It’s important to seal the top, bottom and sides, and the best way to achieve this is to have the curtains drop to the window sill or floor. A curtain valance can further reduce the infiltration of air.

Two-panel curtains should overlap in the centre to prevent air from escaping through the gap in the middle. Panels are more advantageous than single side curtains, as they can stay wide open during the day to accumulate daylight, especially during winter. Keeping them open will also help control the condensation and moisture buildup.

Curtain tiebacks & holdbacks can also keep the panels open, adding style points as a bonus.

Thermal Curtains to Match Home Decor

Insulating curtains are highly functional features; however, that doesn’t imply bulky, unattractive designs. Quite the contrary, a wide range of readymade curtains in a variety of patterns, textures and colours makes it easy to find the model that complements and elevates any home decor. 

Thermal designs can be mix-and-matched with sheer curtains or semi-opaque lightweight models to add even more decorative value. 

Dark tones of emerald green, amber, navy or garnet make the room feel warmer and add luxurious vibes to highly textured fabrics. At the same time, light hues of peach, beige, or ice blue on a silky surface promote fresh cosiness and trick the eye to make the room appear more spacious. 

Things to Consider When Buying Thermal Curtains

To get the maximum out of the curtain’s insulation properties, it’s recommended to keep the windows closed when an air conditioner or heater is on. An annual inspection of the area, followed by sealing any cracks around windows, will support the function and prevent the air from leaking.

Layering promotes efficiency. A combination of window blinds and a thermal curtain will further prevent the formation of air gaps. 

Full-length insulation curtains are more efficient to slow the air from entering or leaving a room.
