How to Choose the Right Type of Drywall to Cover Your Walls or Ceiling

Since its invention in 1916 and rapid growth of sales in the 1940s, the popularity of drywall has remained the same and even more booming. Supplied in standard sizes (4 x 8 feet is the most common), it is used to create and/or cover large, flat surfaces. This common wall and ceiling material is made by compressing gypsum plaster to create rigid sheets, which are covered on each side with thick paper. A range of its options varies from colour and thickness, size and type of edge to its functionality. Discover how to make the right choice for proper drywall installation.

  • Choose the correct sheet size and thickness
    The most common size is 4 x 8 feet, much larger lengths are also available. Try to choose a size that minimizes the number of seams necessary when installing drywall.

The most common thicknesses are 3/8 inch and 1/2 inch. Thicker sheets are required if there is a large gap between studs or joists and nails or screws will be far apart.

  • Choose the correct side

One side of standard drywall sheet is pale grey or ivory, the other is darker grey or brown. Installing drywall put the lighter surface facing into the room.

  • Choose the correct edge

Square-edged sheets are best for plastering walls and ceilings, and taper-edged sheets for drywalling.

  • Choose the correct function

Moisture-resistantare used in areas of high water usage — for kitchen or bathroom drywall installation as a base for tiles.

Vapor-resistant (foil-backed) have paper on one side and a silver foil-like layer on nondecorative side. They are good for cold climate conditions, not for moisture-resistant materials or humid climates

Fire-resistant due to high fireproofing qualities are used for installing drywall in integral garage ceilings, some corridors and stairwells

Abuse-resistantare produced with a thick polystyrene layer bonded to the nondecorative side that provides higher heat insulation. They are used for installing insulation in garage walls.

Soundproof – greater soundproofing qualities are good for installing wall and ceiling drywall in apartments or condos

Mold-resistantare usually produced in purple colour and made to resist the growth of mold and mildew. They are ideal for areas with a high level of moisture, for basement or bathroom drywall installation.

Being as simple as it looks, drywall is incredible and versatile material, qualities of which can vary and be adapted to very specific purposes of proper drywall installation.
