Plasterboard — Why All The Colours?

Why are there so many different types of plasterboard? Roger explains.

What types of plasterboard are there?

Moisture-resistant plasterboard

In the core of moisture-resistant plasterboard are some additives which repel moisture. These plasterboards are the only suitable plasterboards for kitchens and bathrooms as the humid environment will otherwise decay the quality of the board over time and can result in loss of effectiveness of any insulating properties. Using non-moisture-resistant plasterboard in a moist area will lead to damp, rot and mould over time.

Acoustic plasterboard

Opt for acoustic plasterboard and you’ll get additional benefits over just being able to finish off the room. Acoustic plasterboard will keep the sound out of the room and reduce how noise travels between rooms to give a more private and comfortable life for those living there. Utilising acoustic plasterboard in a living room refurbishment, for example, will mean that a loud movie won’t disrupt a quiet chat in the kitchen.

Damp Proof Foil Backed plasterboard

Damp-proof plasterboard is equipped with a layer of foil attached to one side. It can be used in environments that are associated with an appreciable level of moisture (such as kitchens).

Fire-resistant plasterboard

Fire-resistant plasterboard does exactly what it says on the tin. It’s important to become familiar with and choose the right fire performance rating as each rating denotes a different thing. Some fire-resistant plasterboard may be non-combustible, whereas some may offer 240 minutes of fire resistance before it will catch fire. If fire-resistant plasterboard isn’t specified and is just an optional extra, it’s worth choosing what suits your application best. If it’s specified then pick the correct performance rating to meet building regulations.

Insulated plasterboard

Insulated plasterboard is a favourite amongst dry liners as it’s so easy to install. It’s essentially a piece of insulation board faced with plasterboard but the fact that they’re already bonded together and ready to go makes the process faster and more efficient than if you were installing a layer of insulation and then plasterboard. Just like regular plasterboard, this type can be finished without plastering over too.

Your videos are absolute gold. It is impossible to find construction people to help out around here - so I'm DIY'ing almost everything.

Bit of a joke regarding new builds & sound reg.s when most party walls are total s**t & you can hear your neighbours all day, glad we"re in an old terrace cottage now - good vid mate :)

[Morning_Rays]

Thank you. Your videos are very useful for us DIYers.

love getting a bit gypsum in my eyes, real lush

Roger, Ever thought of adding a ‘Skill Builder Factory Visit’ to your channel? I think most of us would appreciate your take on how the things we use are made. Given the size of your channel the manufacturers would roll out the carpet for you too. The added benefit is when you know how stuff is made it means you apply it better.

I worked at a hospital last year where they built a new Xray room. They had that blue colour sound proof plasterboard which I had never seen before plus they had lead lined plaster board which I never even knew was possible. The board sizes were smaller, 2 x 8ft and due to the weight it took 3 men to lift the sheets to prevent the plasterboard snapping under its own weight. Also before attaching the lead lined p/board, the chippy tacked on a 3" lead tape to the entire length of timber studs. This was to ensure no radiation was able to leak through the wall.

I have been a plasterer for the last 30 years Roger knows what he is talking about I must admit even I got a good few tips

[kelstra]

Interesting how these things vary for different countries. In Australia the thickness are 10mm, 13mm and 16mm. The Yanks are big on their usual overkill, they seem to only know 5/8'' board - antique system of measurement as well. We also have an impact resistant board which I'm sure you have over there - it's called Impactchek here but would be a different name over there.
Standard plasterboard has never been approved here for fire resistant construction - regardless of how many layers. Fire rated board is required - called Fyrechek here.

Thanks Roger, at last a video I can understand. Some people get so technical my head spins.

Good tip re: sealing plasterboard and filler if doing the tape and fill method.
I’ve done this quite a bit in my house when dry lining or over boarding a ceiling and if you taper out the joint to about a foot on either side, and seal (I can recommend Zinsser Guardz) it’s invisible even with a raking light; matt paint will help, of course, as you say.

As I understand it sound proof boards are also fire rated the same as pink boards. Standard plasterboard can be double tacked to provide the same fire and sound resistance and has a much better u value. I would choose sound boards on all partitions and standard on external walls if cost was not an issue.

[Mike-grok]

I had no idea, quite amazing how plaster board has evolved thanks for another great video 👍

[gmks]

Well explained thanks. I'm not in the trade but found it very interesting.

[michaelbennful]

Love the channel Roger, thanks as always.

I have a downstairs bedroom that shares a wall with the kitchen and after double skinning with acoustic plasterboard the sound has been cut way down. Great stuff but very heavy!

[RobGreenCOMPOSER]

Absolutely fucking nuts how much this guy knows.

[josephmurray]

As a diyer I am greatful for videos like this, doing a job in a bathroom that had leaks around the bath whit an overrbath shower, bought the moisture resistant boards and am covering it whit Fibo panels as I cannot get a tiler and have zero tiling skills, hoping for the best .

15 mm fire line plasterboard gives fire protection for thirty minutes . I am just finishing a fire proofing job on a 90 foot tall smoke tunnel in an apartment block. Whole thing had to ripped out and new metal stud walls placed on 3 steel beams. Walls had to be double boarded with 15 mm fire line plasterboard to achieve 60 minutes fire protection on the stairwell side and the smoke tunnel on the other side.

I have never seen your eye color before, so unique

[Takeitlightly]

Always great for some expert advice! Cheer and thanks.

Only recently picked up some to do a job in the bathroom, luckily it was green. Cheers for the info.
