GARAGE CEILING INSULATION OPTIONS

11fernsroad

Hi

Our master bedroom is on top of a double garage,which has got intact artex ceiling.But the room above is really cold as compared to other bedrooms.

What are the options to insulate the ceiling below.Not keen on lifting the floor boards or tearing down garage ceiling.

I was hoping more like applying insulation board directly onto present ceiling.Is it a fire hazard or does not comply with building regulations etc?

I doubt that the Artex ceiling meets building regs (if it ever did)   I think that warmth is to be preferred to a pretty Artex finish.

Our house has a lounge over the garage and that was cold.  We filled in the joists with fibre glass and then double overlapping plaster board.

But that route for me would mean opening up present ceiling.I was hoping to apply insulation boards directly onto present artex ceiling

This is what I would do too. Fibreglass & rockwool are both noncombustible unlike PUR/PIR or polystyrene. Once the void is filled, use either a double layer of fire rated plasterboard or cement board. The OP needs to be careful of taking down their ceiling - Depending on the age of the property, it could be an asbestos containing material. So get it tested first.

I guess you don't know whether the void between the bedroom floor and garage ceiling is empty and ventilated or not? If it is, then there's zero point in adding anything to the garage ceiling.

To gain access will mean either removing the ceiling or lifting the floor, neither of which you wish to do.

What is currently on your bedroom floor? Could you lift this, and then lay down even a thin layer of fibre insulation board, and refit the covering? At the same time checking there are no draughts coming up through the floor, or around where it joins the skirting boards...

That should be very little cost, relatively little disruption, and be pretty effective (if a cold floor is the main issue).

I think, generally, non-combustible isn't the same as fire-resistant / fire rated. For a garage it's better to use the latter grade of the same rockwool.

Cavity wall insulation is blown in through holes drilled for the purpose.  Would it be possible to do the same into the voids above the garage ceiling?  Clearly the insulation would have to be fire resistant.

That can be done.
