Cinema and Performance Venue Curtains: Blackout and M1
A cinema or performance venue places three demands on its curtains: complete blackout for image quality, acoustic treatment for sound, and a fire-resistance class compliant with type L public-access buildings. These curtains are designed to specifications, not from a catalogue.
This guide details these three requirements, sets out the fire-reaction classes that apply to type L, and explains how to move from the specifications to a quote.
Three requirements for a performance venue
A curtain for a performance venue or cinema meets three needs at once. Blackout, to achieve the darkness projection requires. Acoustics, to control sound and reverberation. And fire safety, because these venues are type L public-access buildings subject to fire-reaction requirements. Neglecting any one of these points compromises operation.
Complete blackout, the condition for the image
On a screen, the slightest stray light degrades contrast and washes out the image. A projection room therefore aims for complete darkness: a dense, covering curtain with no light leakage at the sides or top, plunging the room into darkness. For walls and openings, blackout is often combined with a fire-resistance class, a topic covered in our article on the fireproof blackout curtain.
The acoustics of the room
The curtain also acts on sound. A heavy, thick textile, such as velvet, absorbs some of the reflections and reduces reverberation, which clarifies sound reproduction. Hung on the walls, these curtains can modulate the acoustics depending on whether they are open or closed. Exact performance depends on the fabric and the treated surface, to be defined according to the room.
The fire-resistance class in type L public-access buildings
Performance venues and cinemas are type L public-access buildings, subject to fire regulations. Several fire-reaction requirements apply, depending on the element:
- Stages and platforms: curtains rated M1, whatever the surface area.
- Projection screen: M3 material minimum, with borders rated M1.
- Partition elements: M3 minimum.
- Enclosed stairwells M1, escape routes and rooms over 50 m² M2 (rules common to all public-access buildings).
The exact class depends on the space concerned and remains validated by the safety commission or the establishment's inspection body. Our guide fire-resistance class for curtains in public-access buildings details the framework, and our guide to the M1 and M2 standards explains the classes.
From the specifications to the quote
For a venue, these curtains are not ordered in standard sizes. Kurtens produces to specifications: blackout, acoustic treatment, extra-long height and fire-resistance class are defined according to your spaces and your constraints. The M1 class is available on request. Every project starts with a conversation about your needs, followed by a quote. Detail your installation on our professional curtain quote page.
Frequently asked questions
What fire-resistance class for the curtains of a performance venue?
M1 on stages and platforms, M2 in escape routes and rooms over 50 m², projection screen M3 with M1 borders. The exact class depends on the space and is validated by the safety commission.
Do a cinema's curtains have to be blackout?
Yes. Image quality requires complete darkness, so a dense, covering curtain with no light leakage at the sides or top.
Does a curtain improve the acoustics of a room?
Yes. A heavy textile, such as velvet, absorbs some of the reflections and reduces reverberation. The effect depends on the fabric and the treated surface.
Does Kurtens supply M1-rated curtains?
Yes, on request, built into the project specifications.
