Hi,
Why do builder's not put insulation in the ceiling of the garage?
Does anyone know how much it would cost to do?
I plan on turning the garage into a kids playroom.
Cheers,
Michelle

An excellent question...particularly when the garage and house share a common roof....freaked out the other day when I found no insulation in our garage....nice draft coming through the manhole too. mmm....donuts Homer Simpson 1956- Links: Site Costs Ready Reckoner | H1 Addiction Medical Advice | Château TDL: The Backyard Re: Ceiling Insulation in Garage 4Sep 12, 2008 12:00 am I'm pretty sure ours had to have it because it was part of the main roof.

A 16 pack of R3.3 x 580mm will set you back about $55 - it will cover 12.2 sq. metres Re: Ceiling Insulation in Garage 7Sep 14, 2008 8:27 pm ...or spend a bit extra on the polyester stuff - it doesn't give you the itchys Re: Ceiling Insulation in Garage 8Nov 03, 2008 5:01 pm Dukekamaya Its standard for a garage ceiling not to be insulated.

This is my next job, especially at that ~price. I've just been here (posted elsewhere on this forum) http://www.environment.nsw.gov.au/rebates/ccfcir.htm and am also up for a new washing machine too. Re: Ceiling Insulation in Garage 9Nov 04, 2008 8:26 pm We had been thinking the very same thing!
It gets so hot in the garage in summer and also the garage door attracts its share of heat to. We will add more gold batts in and I am going to get some sections of polystyrene cut to fit into the sectional door back to also keep the heat away. It does make the rooms near it noticably hotter in summer. even the internal wall facing the garage space heats up (double brick) Re: Ceiling Insulation in Garage 10Jan 04, 2009 11:09 pm I have been wondering if we should put insulation in the garage as it will be next to our bedroom and I would imagine there would be some heat transfer through the wall and also in the roof.
I also wondered if we should insulate the Alfresco area because of the heat transfer from the roof and if your sitting under it on a warm day it may make a difference. Any opinions on this one would be gratefully accepted as we will hopefully have council approval soon! Re: Ceiling Insulation in Garage 12Jan 15, 2009 8:41 pm Insulating the garage ceiling when under the main roof is a bit of 6 of one and half a dozen of the other. Mine is insulated (ceiling and all walls) but it is the hottest room on a hot day, reason - the metal panel lift door transmits heat straight in. What is essential though is to have the garage walls adjoining other rooms insulated. However when a hot car enters and the door is shut it heats up the garage, OK in winter but not in summer. With an insulated ceiling the garage does take longer to cool down. If you have a roller door that faces west or east it will get very hot. Insulation will just keep the heat in longer. You can however have a large vent that lets out the hot air into the ceiling space, however if the ceiling does not have very good ventilation it won't help. BTW a spinaway on a house roof is not good ventilation, its heat removal capacity on a hot day is miniscule. I once saw a house which had a double panel lift door facing East, a black door! The garage got so hot the cavity sliding doors accessing the house buckled so much they couldn't be opened. (the builder had advised against using cavity sliders for that very reason.
One tip which may help - put rubber doors seals around the garage to house door, keeps out heat, cold and car fumes . Johnnojack Re: Ceiling Insulation in Garage 14Jan 16, 2009 7:47 am Johnnojack .

Johnnojack Great tip about weathersealing the internal access! Insulation can mean two things here. Bulk insulation such as batts are more useful in keeping in winter warmth then keep out summer heat . They block convective transfer of heat. However, most of the energy during summer is in the form of radiation. This can be largely blocked by a radiant barrier such as Sisalation under the roof and/or the walls (rejects >99% of heat radiation). It can even have a few gaps (unlike batts) because heat rays can't bend around corners (unlike hot air). Usually you will need to combine both products for an optimum year round effect. I agree that whirlys aren't that useful (especially not if you are just ventilating the roof space by itself). See: http://forums.envirotalk.com.au/Whirlyb ... t8445.html Found the answer.
