Gypsum boards have become a cornerstone in modern construction, offering versatility, durability, and aesthetic appeal. Whether you’re renovating a home, constructing a new space, or exploring options for interiors, understanding gypsum boards can help you make the right choices.
Here are the most commonly asked questions answered by HomeSure experts to help you navigate gypsum boards with confidence.
1. What is a Gypsum Board?
Gypsum board, also known as drywall-board or plasterboard, is a building material used to create interior walls and ceilings. It consists of a gypsum plaster core sandwiched between two sheets of thick paper. Lightweight and easy to install, it offers a smooth surface for painting or finishing and is resistant to fire, mold, and moisture.
2. What are the Types of Gypsum Boards?
Gypsum boards are available in various sizes and types to suit different construction needs.
By size: 9mm, 11mm, 12.5mm & 15mm
By Type-
1. Regular Gypsum Boards
2. Moisture-resistant Gypsum Board
3. Waterproof Gypsum board,
4. Fireproof Gypsum Board
3. What does the gypsum board do?
Gypsum board serves as a versatile paneling material for walls, ceilings, partitions, and even floors. It provides thermal insulation, soundproofing, and fire resistance, making it ideal for residential, commercial, and institutional spaces.
4. How do I choose the right gypsum board for my project?
• General areas: Use standard gypsum boards
• Wet zones: Opt for moisture- or Mold-resistant boards
• Fire-prone areas: Fire-rated gypsum boards are essential
• Sound-sensitive areas: Choose soundproof boards
Consulting an architect or contractor is always recommended for selecting the ideal board based on your needs.
5. What is the composition of a gypsum board?
Gypsum board consists of a core made from calcium sulfate dihydrate (gypsum), a naturally occurring mineral. This core is bonded between two durable sheets of paper, making it easy to cut, install, and finish.
6. Are there different sizes and thicknesses of gypsum boards?
Yes. Common sizes include 6’x4’, 8’x4’, and 12’x4’, with thicknesses ranging from 9mm to 15mm. Thicker boards are preferred for ceilings or fire-rated applications, while thinner boards suit partitions and lining.
7. Is gypsum board good for false ceilings?
Yes. Gypsum boards, especially HomeSure GypEX, are highly suitable for false ceilings. They are lightweight, offer design flexibility, and resist moisture and fire—making them a durable choice over traditional POP.
8. What is the cost of gypsum board ceiling design?
The average cost of gypsum false ceilings ranges from ₹100 to ₹130 per sq. ft., inclusive of both HomeSure materials and installation. The final cost depends on the design complexity and surface area.
9. How long do gypsum ceilings last?
Gypsum ceilings can last 20+ years under normal indoor conditions. However, exposure to water leakage or poor maintenance can reduce their lifespan.
10. Are gypsum boards suitable for ceilings and roofs?
Yes. Gypsum boards are ideal for interior ceilings. However, they are not suitable for external roofing. When installed in dry interior spaces, they offer excellent longevity and performance.
11. Can gypsum boards be used for exterior applications?
No. Gypsum boards are not recommended for exteriors as they can’t withstand continuous exposure to rain, moisture, or UV rays. Cement boards or exterior-grade panels are better alternatives for outdoor use.
12. Is gypsum board waterproof?
While standard gypsum boards are not waterproof, moisture-resistant variants with water-repellent additives and green liners are available. These are ideal for kitchens, utility areas, or other mildly damp spaces.
13. Can gypsum boards be used with tiles?
Moisture-resistant gypsum boards can serve as a tile substrate in dry to mildly humid areas. For wet zones like bathrooms or washrooms, cement boards are recommended for better durability.
14. Is gypsum board good for walls?
Absolutely. Gypsum boards are widely used as wall coverings for both residential and commercial buildings. They are quick to install and provide a smooth surface for paint or wallpaper.
15. How strong is standard gypsum board?
HomeSure GypEX gypsum boards are robust enough for wall, ceiling, and partition applications. They can be attached using screws, nails, or adhesives directly onto wood or metal frames.
16. Can gypsum boards crack over time?
Minor cracks may appear due to structural movement, temperature changes, or improper installation. Proper joint treatment and stable room conditions help avoid these issues.
17. Is there a way to paint gypsum plasterboard?
Yes. Before painting, apply a plasterboard primer to smooth the surface and ensure even paint absorption. Then proceed with your preferred wall paint.
18. What surface decorating options exist for gypsum boards?
Standard gypsum boards can be decorated with paint, texture coatings, wallpaper, or tiles (in case of moisture-resistant variants). They offer flexibility in both design and finish.
19. Are gypsum boards fire-resistant?
Yes. Gypsum has a naturally non-combustible core. When exposed to fire, it releases moisture in the form of steam, acting as a fire retardant and helping contain the spread of flames.
20. Are gypsum boards termite-proof?
Yes. Since gypsum is inorganic, it does not attract termites, unlike wood-based materials. This makes it a smart choice for pest-prone regions.
21. Are gypsum boards sustainable?
Gypsum is a naturally occurring mineral, and gypsum boards can be recycled and reused in manufacturing processes, reducing environmental impact and material wastage.
22. What is the lifespan of gypsum boards?
When installed correctly and protected from moisture, gypsum boards can last well over 50 years, maintaining their structural and aesthetic integrity.
23. What are the steps involved in installing gypsum boards?
1. Prepare the framing
2. Cut the board to size
3. Fasten with nails or screws
4. Tape and fill joints with compound
5. Sand, prime, and finish the surface
24. What are the disadvantages of using gypsum boards?
• Impact-sensitive: Can dent or crack if hit
• Water-sensitive: Not suitable for wet environments unless treated
• Limited flexibility: Hard to apply on curved surfaces
25. What is the difference between gypsum board and POP (Plaster of Paris)?
• Gypsum board: Factory-made panels, quick to install, water- and fire-resistant
• POP: On-site application, more labour-intensive, requires a skilled application
Gypsum board is the preferred modern choice due to its consistency and ease.
26. Can gypsum boards be used with sound insulation?
Yes. Specially designed soundproof gypsum boards are available for areas that require acoustic control, such as offices, studios, or bedrooms.
27. Can gypsum boards be curved or bent?
Standard gypsum boards have limited flexibility and may crack if forced into curves. For curved surfaces, flexible gypsum boards or alternative materials are better suited.
