Key Benefits of
Top Down/Bottom Up Thermacell Blinds
CORDED, CORDLESS & MOTORISATION
As the name suggests, this type of blind has the function to lower from the top of the opening to the bottom of the opening. This shade can be drawn completely to the top or bottom of the opening, or anywhere in between, giving unlimited light control and privacy options. TDBU also has the standard feature of lifting the bottom of the blind up. They provide precise light and privacy control, making the shade an ideal solution for rooms that require natural, indirect light, while still providing a certain level of privacy when required.
CORDED - With the corded TDBU application there will be a control cord either side of the blind. The right cord will control the lowering of the shade (middle rail), whilst the left will control the lifting (lower rail).
CORDLESS - The blind will be raised and lowered by hand, there will still be cords visible in the centre of the blind when the blind blanket is lowered, in the opening to have a gap between the headrail and blind. Not available in a 25mm cell size
MOTORISED - Experience effortless comfort and control with motorised Thermacell blinds. Achieve your ideal lighting with a simple voice command, a tap on your phone, remote, or directly from the shade itself. Designed for smooth, quiet operation, these blinds are perfect for hard-to-reach windows and everyday convenience. Enjoy enhanced insulation, superior light control, and a sleek, cordless design that adds both safety and style to your space.


NOISE REDUCING


Thermacell blinds help reduce noise through their unique honeycomb (or cellular) structure, which creates pockets of air within the fabric. These air-filled cells act as a natural sound buffer, absorbing and dampening sound waves that would otherwise pass through windows. Here's how they contribute to a quieter space:
-
Sound Absorption: The multiple layers of fabric and air pockets help absorb ambient sounds like traffic, neighbors, or street noise, reducing the overall sound level entering a room.
-
Barrier Effect: The dense material and the layered design act as a barrier that disrupts the transmission of sound vibrations, particularly mid- to high-frequency noises.
-
Layering for Extra Dampening: Room-darkening and blackout options—especially those with coatings like mylar—further enhance sound insulation by adding thickness and mass to the blind.
While Thermacell blinds won’t soundproof a room entirely, they can noticeably reduce outside noise and contribute to a more peaceful indoor environment, especially when paired with other insulating features like double-glazed windows.
ENERGY EFFICIENT
Thermacell blinds are exceptionally energy-efficient due to their unique honeycomb structure, which creates insulating air pockets that help regulate indoor temperatures year-round. These pockets trap air, acting as a barrier that minimizes heat transfer through windows—keeping warmth inside during winter and blocking heat during summer. This natural insulation can reduce heat loss by up to 60%, resulting in lower energy bills and a more comfortable living environment. Additionally, various fabric options enhance their performance, offering light control and further thermal benefits. Here’s how Thermacell blinds contribute to energy efficiency:
-
Honeycomb cells trap air, reducing heat transfer through windows.
-
Minimize heat loss in winter by keeping warm air inside.
-
Block solar heat in summer, keeping interiors cooler.
-
Reduce reliance on heating and cooling systems, leading to energy savings.
-
Available in light-filtering and blackout fabrics, including mylar-coated options for added thermal performance.
-
Maintain stable indoor temperatures year-round, enhancing comfort and reducing HVAC strain.
