01 / Position1
Roof or wall
A roof blind sits in the hottest part of the building and needs the fixing and the void detail right. A wall blind behaves much like any interior roller blind.

Application
Sunscreen fabric for conservatory blinds
Blinds mounted inside a glazed roof or against a conservatory wall sit in a hotter, more humid environment than an exterior drop, and that changes what matters.
Interior mounting
The fabric sits behind the glass, not in front of it.
An interior blind works on a different principle from an exterior one: the solar energy has already passed through the glass, and the fabric absorbs part of it inside the room. Fabric in a roof lantern also sits in the hottest position in the building. That is why interior blinds are usually specified at 3% for glare, and why the fixing detail and the ventilation of the void above the blind matter as much as the fabric.
Openness
3% is the usual choice for interior glare control; 5% where a brighter room is wanted.
Cleaning
Lukewarm water with mild soap on a soft cloth.
Fastness
Tested to ISO 105-B02 for colour fastness to artificial light.
Specifying
Interior blinds are a different job
The fabric is the same; the environment around it is not.

02 / Colour2
Lighter colours stay cooler to the touch
A light colour reflects more of the solar energy that has already entered the room. In a conservatory that is usually the better choice, at some cost in glare control.
