Browse Forums Windows & Doors 1 Jan 03, 2014 6:48 pm Im looking into putting glass frosted bricks (190x190x80) in my staircase void to create a bit of light. Problem is it will be facing dead west, and im looking to add light in the area dont want the westerly heat. I was avoiding the window altogether buy will need some natural light Any comments? Any other solutions? Re: Glass Bricks R rating 3Jan 06, 2014 12:21 pm Stewie D Glass blocks from memory have about the same R- value as a double glazed window but personally I'd get the window so if you want you can open it for added ventilation. Stewie If you don't need a good sized opening window in that location I have seen glass brick sized 'windows' so that you can have a glass brick wall and still have ventilation. I googled and found some pictures for you. The one I was thinking of is described as a "Standard Pop Out Vent Window" but it turns out there are a few different ways you can do it on that website and perhaps there's more on other websites. I don't know if they were available when we built our glass brick brick wall but the room has other ventilation anyway so we probably would not of been interested. But for you it might be worth considering. Our glass brick wall does not face west so I can't say anything specifically about that, but we really like it. http://www.glassblockconstruction.com/g ... ntilation/ Re: Glass Bricks R rating 4Jan 06, 2014 12:46 pm Thanks Guys, I contacted a manufacturer and he said the same, it has the same U-value as double glazing. I have minimised and limited the amount of windows on the western side of the house, what if i were to install a double glazed window, then get the window UV tinted (maybe inside and out?) I am working hard to achieve a solar passive home, im so close, its just that bloddy staircase! Re: Glass Bricks R rating 5Jan 06, 2014 9:04 pm Even a single skin glass window with the tinting makes a huge difference for a west facing window. From what I understand the tinting is very good at keeping heat out but not so good at keeping heat in. Stewie Re: Glass Bricks R rating 6Jan 07, 2014 7:43 am The Uw won't help, your problem is one of solar heat gain, and for that you need a low-E glass, I don't believe there is a low-E type of glass block. Here are some glass block data from WERS http://www.glassblocksqueensland.com.au ... wers12.pdf I suggest a traditional double glazed fixed window with one pane in low-E and the other in a decorative architectural glass (http://www.hartleywilliams.com.au/index ... -list-1153 - these maybe won't work, they are only 3mm thick, but I leave it with you as an idea), or incorporating a lead-light, or http://daorah.com.au/decorative-glass-painting/ .
