Newly built house - studs or OSB?

[Paulina123]

Hello,

My partner and I are going to build a house with Movehome. From what I've read and understood, the interior walls are insulated but are gypsum walls. So we can't, for example, hang a TV on the wall.

I talked to our contact at Movehome about this and was told to bring it up at the start-up meeting. The salesperson mentioned that we could ask the carpenters to put up some studs on the walls where we wanted to mount a TV. The salesperson also said that we shouldn’t install studs on too many walls as it might interfere with/damage the insulation.

This is our first house, and we are not handy at all. So it might be a silly question, but why do you put up studs and not an OSB board? As I understood, we had to tap on the wall before we could hang the TV (to know where the studs are), but if you put up OSB, you wouldn’t need to do that, right? Or do you need to install both studs and OSB?

I hope someone handier than me can answer☺️

A regular TV can be hung on drywall if you use the right tools. It's no problem. If you know exactly where you want to place the TV, studs can be an option. But it works anyway.

Place OSB behind the drywall, it will be a bit more expensive, but what does it matter when you can put up whatever you want on the walls without thinking, and in the event of :: OOPS wrong place for the hole with large screw, or grandma's large hallway mirror from ceiling to almost floor, you don't need to search for studs.

Hello,

My partner and I are building a house with Movehome. From what I can read and understand, the interior walls are insulated but they are plasterboard walls. So we cannot, for example, hang a TV on the wall.

I talked to our contact at Movehome about this and was told we could bring up the issue at the construction start meeting. The salesperson said we could ask the carpenters to put up some studs on the walls where we wanted to hang a TV. The salesperson also said we shouldn't put up studs on too many walls because it could interfere with/ruin the insulation.

This is our first house and we are not handy at all. So it might be a silly question, but why put up studs and not an OSB board? As I understood it, we would have to tap on the wall before hanging up the TV (to know where the studs were), but if you put up an OSB, you don't need to do that, right?

do you mean OSB on the plasterboard to use as a mounting board?

you eliminate a cost (let's say 50 SEK/sqm depending on the board, plus labor and screws)

Well, OSB under drywall.

It's common to install OSB everywhere as it provides increased stability, sound insulation, and simplifies mounting of TVs and heavy pictures/mirrors.

However, it's a cost issue, costing slightly over 50 SEK/sqm in materials plus installation, maybe 100 - 150 SEK in total.

A molly in simple plaster can hold 20kg. A TV is often mounted with four of them. A large flat TV weighs around 20kg.

 

[Paulina123]

Okay, it seems like OSB board is preferable despite the cost issue.

A follow-up question:

Does it take longer to install an OSB board than studs? If it's only a cost issue for the material, it might be easier to convince the house supplier to install OSB instead (you're actually not allowed to change/add anything in a movehome house).

You must have the reglar too!

Reglar, insulation, OSB, and finally drywall. We also reinforce certain walls with 15mm plywood, for example in bathrooms and kitchens.

you absolutely do not need any OSB or plywood in the walls to hang things.
a TV is no problem to hang on a regular gypsum board.

it's more if you’re going to have a wall-mounted radiator that people will sit on that you should consider short bridging.

Now, forgive me, but I can't stay silent. It seems that TS is asking about something and some of us are responding based on experience, about what can and can't be done in terms of construction. I have answered that the best is to place a board behind the plasterboard, and I believe that many would agree with me.

To avoid future problems with things like stability and mounting various things on the walls, not placing a board is like trying to have your cake and eat it too; it will cause problems later on. I've used molly bolts, which I find to be an abomination because they can't be dismantled without creating a large hole.

If no board is mounted behind, it becomes a single layer of plasterboard. What is that? Think about it yourself when the kids throw open a door, the handle goes right through the wall. It's no fun with a broken wall.

To then firmly state that a TV is held up with a few molly bolts, of course it stays up but at what cost if they don't anchor as they should?

In the end, it's TS who decides and is responsible for the decision, but they should seriously consider what's been presented by various participants here.

OBS is really not needed in walls.
If anything, add an extra layer of gypsum, it's cheaper and you'll get other good properties too.

Movehome does not give you the opportunity to change anything; that is the point of the concept. However, you can ask the contractors to install OSB between the studs on the walls where you are considering mounting heavier items like a TV, etc. Installing OSB behind the drywall involves much more work with things like door frames.

I'm not trying to discredit anyone, but having single drywall is creating problems. Having double drywall isn't completely wrong, but the issue remains with hanging things on drywall. The fasteners available on the market are designed to be installed and not removed later without leaving large holes in the walls.

no that's wrong. there won't be any extra work with anything else like frames.

if you choose OSB in certain places, you just insert it between the studs with sheet metal strips being the cheapest or with short brackets.

why would there be more work at the doors?

I am not looking to discredit anyone, but having single-layer gypsum is creating problems. Having double-layer gypsum is not entirely wrong, but then there's the issue of hanging things on the gypsum. The fasteners available on the market are designed to be put up and not removed later without leaving large holes in the walls.

Well, it is incredibly easy to repair and cost-effective compared to installing OSB on all walls.
