Skylight Blinds: Roller Shades for Sloped & Flat Skylights

Skylights bring the best light in the house — and the worst heat. A skylight blind is the difference between a bright room and a greenhouse at 2 pm. Because skylights slope, standard window blinds will not work: the fabric must run on side rails or tensioned cables so it cannot sag.

Why skylights overheat rooms

Sunlight through a skylight lands nearly perpendicular to the glass at midday — the angle where it transfers the most heat. The air below warms and pools at ceiling height, and since hot air rises, the heat has nowhere to escape. A reflective-backed shade stops most of it before it enters the room.

The three systems that work on slopes

• Tensioned roller shades: fabric runs on taut side cables — no sag at any angle, slim profile, the budget standard
• Side-channel roller blinds: fabric runs inside aluminium channels — best light block, near-blackout possible
• Cellular skylight blinds: honeycomb fabric on rails — the insulation upgrade for rooms under the roof

Fabric choice for skylights

1. Sunscreen / light-filtering: cuts glare and heat, keeps the sky visible — living areas
2. Blackout: bedrooms and media rooms — pair with side channels for real darkness
3. Reflective backing: worth it on any skylight that gets afternoon sun

Motorised — and it is not a luxury here

Skylights sit out of reach; a chain hanging from a sloped shade looks wrong and tangles. A battery or wired motor with a remote — or app scheduling — is the standard solution. For high, flat roof lights, it is effectively the only solution. See the motorisation guide for costs.

Measuring a skylight blind

Measure the visible glass width and drop precisely — skylight recesses are rarely square, so measure at three points and take the smallest, exactly as in the measuring guide.
