Acrylic Skylight Domes: Single vs Double Skin, Thermoforming & Sizing

A specification guide for acrylic skylight domes and rooflights — how single vs double skin, grade and kerb sizing are chosen, and what to confirm before ordering. Structural and weather-sealing design stay with your roofing contractor; we thermoform the dome to the specified kerb.

Why acrylic for skylight domes

Acrylic thermoforms into clean domed rooflights at about half the weight of glass, transmits daylight well and is UV-stable outdoors without a coating. It is the common choice for daylighting domes over walkways, atria and industrial roofs.

FAQ

Common questions

Single or double skin acrylic skylight dome?

Single skin is lighter and cheaper for covered or industrial roofs; double skin adds an insulating air gap and reduces condensation for occupied or heated spaces. Choice follows the space below and the thermal requirement.

Can you thermoform a dome to our kerb size?

Yes. We thermoform acrylic skylight domes and canopies to your kerb size in clear, opal or tinted grade, single or double skin. Structural fixing and weather sealing are the roofing contractor’s scope.

Which grade cuts glare in a skylight?

An opal or diffusing acrylic grade spreads daylight and reduces glare and hot-spotting; clear maximises daylight and view; tinted adds solar control.

What is the minimum order for skylight domes?

Production runs start at 20 pieces per design; samples ship in 48 hours from an approved drawing.
