Questions about ceilings
Updated 5 Aug 2026
Planning a ceiling renovation? The right system depends on room height, humidity, lighting, access to services and budget.
This guide compares stretch and plasterboard ceilings and explains how much height each system can use.
A lighting and service plan should be prepared before installation.
Five common ceiling questions
1. Stretch ceiling or plasterboard?
Stretch ceilings install quickly, tolerate humidity well and create a smooth surface. Plasterboard allows levels, integrated services and more complex lighting. The choice follows the room and budget.
2. How much height is lost?
A stretch ceiling usually uses about 3–5 cm, depending on the profile and lighting. A plasterboard ceiling commonly uses 7–15 cm, depending on the frame and services.
3. Which lights are suitable?
LED, recessed and pendant fixtures can work when the system is designed for them. Choose efficient LED lighting with the correct preparation and protection.
4. Can hidden LED lighting be installed?
Yes. It can be integrated into plasterboard coves, niches and perimeter details, or installed using a profile designed for LED strips in a stretch ceiling.
5. What should be considered?
Check room humidity, ceiling height, lighting layout, access to services, budget and the desired visual result before choosing the system.
Frequently asked questions

Can spotlights be installed in a stretch ceiling?

Which ceiling is better for a humid room?
A stretch ceiling generally handles humidity well. A plasterboard system needs the correct board, framing and surface treatment for the room.
