Which is better, PVC ceiling or gypsum ceiling?

Oct 16, 2025

Many homeowners struggle to choose between PVC and gypsum ceilings, thinking they serve the same function—until humidity, sound, or fire safety come into play. PVC ceilings are lightweight, waterproof, and easy to clean, while gypsum ceilings offer better sound insulation, fire resistance, and a more elegant finish. When I first compared PVC and gypsum ceilings […]

What is a T-grid ceiling?

Oct 14, 2025

A T-grid ceiling is a suspended ceiling system built with metal frames shaped like a “T” in cross-section. It consists of T-shaped main runners, cross tees, and perimeter moldings that support removable ceiling panels. From my design projects, I have seen T-grid systems used widely in offices, schools, and retail spaces. They create an easy-access […]

Is there waterproof gypsum board?

Oct 13, 2025

Gypsum board is naturally vulnerable to water, but specialized versions are designed to resist moisture in damp environments. There is no truly “waterproof” gypsum board—only water-resistant types treated to slow moisture absorption. In my experience, the term “waterproof gypsum” is misleading. Water-resistant boards are made with treated gypsum cores using hydrophobic additives like silicone, and […]

Is gypsum board fireproof?

Oct 11, 2025

Gypsum board is not technically “fireproof,” but it has natural fire-resistant properties that slow heat spread and provide valuable escape time in case of fire. Gypsum board’s core contains about 21% chemically bound water, which releases as steam when heated, absorbing heat and delaying fire growth. In my work, I’ve seen gypsum board hold back […]

Drywall finishing has an official 5-level scale that determines surface quality, finish smoothness, and final appearance before painting or decoration. The five drywall levels range from Level 0 (no finish) to Level 5 (premium smooth finish for high-gloss paint or strong lighting conditions).

What are the disadvantages of PVC false ceiling?

Sep 28, 2025

PVC ceilings look easy to install and maintain. But their weaknesses can cause problems in certain spaces. PVC false ceilings have poor heat resistance, can deform in high temperatures, have low impact strength, and may release harmful substances if quality is low. PVC’s plastic texture does not suit high-end interiors. In places with big temperature […]

Many people compare gypsum board only by price. They miss the hidden costs that show up years later. A standard gypsum board sheet usually costs between 30 and 60 RMB, while waterproof types range from 100 to 150 RMB or more. Cheap boards seem attractive at first, but repairs and replacements in damp areas can […]
