Cassette headbox sizes and projection
Fixed component dimensions for reference and installation planning.
Utopia cassette roller blinds use aluminium headboxes and side channels with fixed external dimensions. The appropriate cassette size is selected automatically based on blind width, drop, and fabric weight to ensure smooth operation and long-term reliability.
| Cassette type | Headbox size (H × D) | Side channel size (W × D) | Typical application |
|---|---|---|---|
| C40-60 | 77 × 73 mm | 55 × 13 mm | Smaller blinds and shorter drops |
| C40-90 | 105 × 95 mm | 55 × 13 mm | Most medium sized blinds |
| C40-120 | 140 × 120 mm | 55 × 13 mm | Wide blinds, long drops, heavier fabrics |
Finished size orders
If you select Overall blind size (finished), your supplied measurements must already allow for the full cassette projection and side channels shown above. These component dimensions are fixed and cannot be reduced.
Headbox selection is based on blind size and fabric weight (typical fabric approx. 400 g/m²). Lighter fabrics may allow a smaller cassette; heavier fabrics may require a larger cassette.
Inside or Outside the Recess
Cassette blinds can be fitted neatly inside the window recess or on the face of the recess for full coverage.
Inside the window recess
Provides a neat, flush finish with the cassette and side channels sitting within the recess. Measure the opening inside the recess and we will apply the correct allowances automatically.
On the face of the recess / wall
Ideal for maximum coverage and light control, or where the recess is not square. If you measure the recess opening and choose face fix, we will manufacture the blind to fully cover the opening.

Thermal and Solar Performance
Utopia Blackout Cassette Roller Blinds are designed to help improve comfort and reduce unwanted heat and glare within the home or commercial space. The blackout fabric and cassette system work together to limit solar heat gain and control light levels throughout the day.
The thermal performance of the fabric is measured using internationally recognised metrics, including transmittance, absorption, reflection, and shading co-efficient. These values indicate how effectively the blind reduces heat transfer through the window.
Transmittance refers to the amount of light and heat that passes through the fabric. Lower transmittance means less heat and glare entering the room.
Block / Reflect measures how much heat and light is blocked or reflected away from the window. Higher values indicate better thermal efficiency.
Absorption is the amount of heat absorbed into the fabric itself. Lower absorption helps reduce heat build-up at the window.
Ultraviolet protection indicates how effectively the fabric shields against UV rays, helping to protect furnishings, flooring, and interiors from fading.
Shading Co-efficient compares the solar heat gained through a window with and without a blind installed. A lower result means better performance at reducing solar heat gain.
Practical benefits
- Helps reduce overheating in sunny rooms
- Improves comfort without relying solely on air conditioning
- Reduces glare while maintaining a clean, modern appearance
- Supports energy-efficient building design

Great cassette blindsVery happy with our UTOPIA Cassette Frame Blind, looks nicer and more robust than another more expensive one we bought and was also faster to deliver. Was easy to install, now we just need some decorating caulk on the sides as our walls are far from straight!0 people found this helpful
