Anyone here tried Radiant Barrier ? Is it works?

Radiant Barrier Tyler

i use similar sheets + cellulose. works well but i think just the foil wont be good enough for our climate. the foil can used to create a second roof and channel away some heat but by all means not all. under my roof and on top of the cellulose its pretty hot. ceiling under cellulose is cool. so go figure.

I've been told that bubble radiant barriers work better than normal ones. Any truth in that? They are more expensive though.

possible since the air sort of works like an insulation. i personally would not just rely on a reflective sheet. you need to ask yourself where does it reflect the heat to? to the tiles which in turn beam the heat back and so forth so what you can do is create a second roof under the roof with those sheets and allow for airflow between sheet and tiles. that way the semi-trapped heat can be moved out. but i think there is still a lot of heat getting into the roof. that is why you should employ several methods of insulation / heat combating to get best results. its often the case that a combination of several things works best. we want to try to add a third option: coating the roof with a (partially) relective paint i.e. grey or whitish to reflect some heat BEFORE it gets into the roof. of course you could also cover the outside of the roof with reflective sheets but i am not sure if this i legal. pretty sure it would look real bad though .

If the entire neighbourhood's houses have their roofs painted white, I would do the same.. but not if I'm the only one

"Branded" reflective sheets like Parsec Thermo-Brite III actually costs more than foil wrapped bubble sheets. I guess you must always have air space in between the sheets and the tiles, and have ventilation tiles to allow the heat to escape.

I was quoted RM 1.20 per sq feet for bubble sheets(without installation), anybody could share their cost for their sheet insulation?

HOW MUCH??

RM300PER ROLL??

and the precentage of reflectivity of heat>?

Cover the whole roof with solar panel lah. Kill two birds with one stone. The heat all absorbed by the panel instead of into the loft and then radiate into the house below, and convert to electricity pulak.

Nice idea. How much is the solar panel cost?

I am lookin at the roof of this old hse I jus bought and was advised to get it fixed – coz the weaving seems ‘out’

I have a couple of choices
1) change the rooftiles completely – gonna cost a BOMB
2) treat the current rooftiles & rearrange them back
3) just rearrange them back

with that three options, I guess I should also install insulator and all. I heard of vry good comments of TSL.

Anyone can advise me on what I should do? and since im renovatin the whole house, I guess I should start with the roof 1st? A latest cost list would also be helpful. Thanks in advance.
