Hi guys, when dot n dabbing insulated plasterboard do you guys plug and screw after?

 

[TonyM]

Yes.

I got some metal hammer fixing last time. Cheap and really solid. The sleeve is actually hollow and it compresses rather than expands.

il have to give them a try nxt time,do they just hammer in?

 

[beddy]

Yeah. Drill the hole slightly smaller and the end is shampfered and just compresses as you **** it in. Finishes flush with the board and just scrim over it

 

[loky11]

Thatl be alot quicker cheers. I also forgot to mention thers shed loads of cables behind wich im worried about hitting when fixing. Its for a mate, hes a sparky so hes gone all out with built in speakers and god knows what else.

if you cant plug and screw you could score the back of the boards, they say the boards can be applied with just adhesive though.

 

[Jurek]

Use dry fix. You can get it for about five quid now including the aplicator

I hate dabbing boards with insulation on the back. I always find the boards have a slight bow in them that is hard to get out

 

[beddy]

If thats the case score a grid on the back with a saw. 300mm apart

Thermaline Super are less prone to bowing than Thermaline Plus. The insulation is different. They are a bit more expensive though

 

[johniosaif]

Cables should of been protected also

 

[beader]

Completely cover the back of the board (insulation side) with a tight coat of adhesive first then dabs will stick better.

Go on ... I'll bite. Why?

 

[murplastering]

[Danny]

Insulated as in foam backed or the foil backed stuff?

 

[scotty1986]

I always like to put a few fixings in the board aswell

Foam backed I think as we call foil backed duplex board.:RpS_thumbup:

 

[theclemo]

I use Thermaline Super boards which foam backed with vapour membrane over. Will try PIR ones, as will save the spaces as more u value.

How much do you pay a board for t super

 

[Danny]

Ah you can dab those foam back ones no problems spoke to @knauf about it a few weeks back... they sent me a video on it as well if the op is interested ;-)

 

[beddy]

think hes just asking about secondary fixings dan, fire regs n all that

 

[loky11]

It was the thermoline ones reason i asked really is because ive known people to dab them and come off the next day but ive dabed them banged a few fixings in and all skimmed and coved now and all still intacted

 

[macfat]

is that video up danny ??? would like to view it. a lot of people in Ireland fix boards with the mushroom fixings ,not a lot trust sticking..what about if foil or paper back ,the adhesive is good enough??
