Limit unwanted window light
Design the fabric, lining and edge overlaps together for the guest-room brief.
Hotels & guest rooms / APPLICATION GUIDE
Control the light. Consider the whole stay.
Guest rooms need dependable light control and easy daily operation. Hotel meeting and event spaces may also benefit from adjustable absorption and presentation blackout, with a different specification for each room type.
LAYOUT STUDY / 12PLAN VIEW · NOT TO SCALE
Illustrative placement study. Curtain coverage, cavity and access are designed for your actual room.
THE ROOM & THE REQUIREMENT
Guest-room light & flexible event spaces.
Even a light-excluding cloth can leave bright gaps above, below and beside a window. The complete curtain assembly must also suit housekeeping, the available stack space and the intended guest operation.
Manage reflective surfaces
Where room assessment identifies a benefit, use appropriate absorption as part of the interior treatment.
Adapt meeting spaces
Separate event-room curtain runs can support presentations, dining and conference layouts.
PLACEMENT & SPECIFICATION
Make the detail
fit the room.
For bedrooms, coordinate the track with the window reveal, returns, head treatment and the space available beside the glazing.
Performance boundaryBlackout curtains do not guarantee sound isolation from traffic, corridors or adjoining rooms. Window and building performance need separate investigation.
Review the test evidence ↗What to establish
- Light-control brief
- Describe the expected result at the bed position and assess light from all openings.
- Housekeeping
- Confirm cleanability, removal for maintenance and fabric care before choosing the assembly.
- Track operation
- Check reach, stack dimensions, fixing conditions and the complete curtain weight.
Confirm the selected material’s certificates, care requirements and the final track and fixing design for your installation.

Bring the room
into the conversation.
Room types, window details, preferred appearance, light-control expectations and housekeeping requirements.
Discuss your project ↗Is dimout the same as blackout for a guest room?
No. Choose the intended light level first, then review the fabric’s stated performance and the installation edges. A dimout fabric may need a separate blackout lining to meet the brief.
