DRYWALL: A BRIEF GUIDE
Initially, let’s discuss a bit bit about what drywall is. These gypsum panels are fabricated from calcium sulfate dihydrate and presumably some components, relying on their function.

Now, a few of you'll know drywall by different names, similar to plasterboard, sheetrock, gypsum, or gyp board. These are all primarily the identical product. Nonetheless, you may test the chemical composition of the drywall you’re contemplating shopping for if the producer disclosed that info.
The explanation why we use drywall is generally a matter of comfort. It’s straightforward to move and apply and largely low cost to switch. It’s actually extra inexpensive than having to place up lath and plaster, which we used to make use of earlier than the Nineteen Thirties. And it’s undoubtedly higher than having to repair concrete partitions in the event that they maintain injury.
Earlier than you rush into shopping for any previous drywall, you ought to contemplate what you’d prefer it to do. So let’s see what sorts of drywall exist.
THE 5 MAIN TYPES OF DRYWALL
As you begin researching drywall, you’ll discover that there are about 5 important sorts. As I’ve talked about, the important distinction between these merchandise is within the components and the paper they use. So primarily, solely the bottom and the final form of the panels stay the identical.
1. REGULAR DRYWALL
Common drywall, in any other case referred to as white board, is the kind of drywall you need to use wherever. This drywall is often white on one aspect and brown on the opposite, with the gentle aspect dealing with the room. The primary factor about common drywall is that you just shouldn’t count on an excessive amount of of it by way of sturdiness. In case you maintain water injury of any form, it'll undoubtedly rot and develop mould and mildew.
So you must preserve it someplace you’re pretty sure mould received’t be capable to get to. Happily, the following kind of drywall endeavors to repair this vulnerability.
2. MOLD-RESISTANT DRYWALL
Not like common drywall, mold-resistant merchandise avoid the paper backing that makes the common merchandise extra vulnerable to mould progress. Additionally they sometimes have a particular coating layer that stops residing organisms from rising.
Though it’s a bit pricier than common drywall, mold-resistant drywall is nice for bedrooms and different rooms you spend a variety of time in. As , inhaling mould can result in severe well being penalties. So it’s greatest to make sure that you by no means come into contact with it in any respect.
A number of merchandise may be thought-about mold-resistant. For instance, paperless drywall is a product that replaces paper with fiberglass. As such, it’s a bit tougher to chop, but it surely’s far more mold-resistant than common drywall.
Blue and purple drywall may be dubbed mold-resistant. Nonetheless, they've moisture-resistant properties as effectively, that are, on this case, totally different. So let’s see what utilizing moisture-resistant drywall will get you.
3. MOISTURE-RESISTANT DRYWALL
If you ask round about moisture-resistant drywall, you’ll almost definitely get pointed towards merchandise like Inexperienced Board. Nonetheless, regardless that it’s moisture-resistant, I wouldn’t depend on it to resist direct contact with water. That shouldn’t be an excessive amount of of a problem in case you apply the proper prime coat or tiles appropriately, although.
Mainly, mold-resistant drywall wouldn’t do a lot good as a result of it’s made to discourage progress, not block moisture. Nonetheless, moisture-resistant drywall could be best for areas that see a variety of water and steam, similar to the lavatory, basement, or the kitchen.
Basically, any such drywall has some kind of waterproof barrier, though some particular person merchandise do it higher than others. Purple drywall, for instance, is nice for partitions and ceilings, and it ought to be high-quality even when it’s in direct contact with moisture. Moreover, Blue Board can be good for tiles, and it might even cut back noise.
All of those merchandise are nonetheless gypsum-based, which isn’t best. If you need one thing actually waterproof, you might wish to think about using a cement board.
4. FIRE-RESISTANT DRYWALL
The ultimate kind of drywall is usually known as Kind X drywall. This title primarily signifies that it has achieved at the very least a 1-hour hearth resistance score for a 5/8-inch drywall and a 45-minute resistance for a half-inch board. It’s nice for stairwells and inside garages, and apart from being fire-resistant, it’s additionally so thick that it might present some soundproofing. Nonetheless, you might not have to go that far, since soundproof drywall already exists.
5. SOUNDPROOF DRYWALL
Whether or not or not soundproof drywall is efficient is an advanced query. Some individuals swear by it, whereas others are extra undecided — and I take into account myself part of the latter camp. Mainly, this drywall is a bit thicker than customary ones, and it ought to technically work. It does have a larger sound transmission class compared to the opposite sorts of drywall.
As at all times, there’s an advanced reply to an advanced query. Soundproof drywall is considerably efficient if you set up it appropriately. Nonetheless, I consider that any kind of drywall might work to soundproof your room when you have the price range. The very best approach I’ve discovered is the one I’ve talked about originally of the article.
Utilizing Inexperienced Glue to create a versatile sound-absorbing layer between two layers of drywall might be the factor to do. It might undoubtedly improve the thickness of the drywall, which is what you want with a purpose to have efficient soundproofing. So let’s see what drywall thicknesses we’re working with, anyway.
DRYWALL DIMENSIONS AND THICKNESS
Drywall dimensions are fairly customary, which makes all of this a bit simpler. The boards are nearly at all times 4 toes vast and might range in size, in line with the peak of your partitions. So count on to see a variety of 4 x 8 drywall, and even ones which might be 9, 10, 12, and even 16 toes lengthy.
If you’re engaged on placing drywall up on a ceiling, you will have to make some changes. Nonetheless, you may nonetheless use these basic dimensions to make your life barely simpler.
Additionally, there are some drywall boards which might be wider than 4 toes, at 4.5 or 8-feet vast, though they’re few and much between. You’re more likely to see smaller 2 x 2-foot piece of drywall, which is used for making repairs.
Drywall thickness normally strikes from 1 / 4 of an inch to five/8 of an inch. For my part, utilizing a quarter-inch drywall could be actually pushing it. In reality, I can’t see it being efficient at something, not to mention soundproofing, until you’re layering it. Nicely — when you have curved partitions, I suppose such a skinny drywall would curve extra simply.
Nonetheless, in every other state of affairs, I’d advise going thicker. Half an inch is just about the usual, and thicker ones are, as you’ve seen, the fire-resistant and the soundproof merchandise. There are even drywall merchandise which might be 3/4 of an inch or as much as an inch thick, though they've particular makes use of.
THE IDEAL THICKNESS OF CEILING AND WALL DRYWALL
So in any case of this, the query stays: what's the best drywall thickness on your partitions and ceilings? Nicely, as I at all times say: the thicker the higher. Nonetheless, that doesn’t imply that you must head straight for the inch-thick drywall.
As an alternative, I counsel sticking to the business customary of utilizing a half-inch drywall for partitions and 5/8-inch panels for the ceilings. You possibly can even double up and use Inexperienced Glue in between. Nonetheless, I actually wouldn’t go any thinner than that.
Particularly with the ceiling, your important concern is to make it possible for the drywall doesn’t sag. The primary method to try this is to make use of sturdy boards that received’t bend, which signifies that you must use thicker ones. Nonetheless, since I don’t know every of your private circumstances, it’s at all times greatest to seek the advice of an expert earlier than beginning a challenge.
