chlow 0 Report post Posted May 25, 2016 Hello All, Trying to find out from those of you with installed window grilles as per the design from my photo. This should be one of the most common design as well for HDB/Condo. I found that there can be different variations for the spacing and contractor/installer will seldom or never talked about it during quotation. What are all your grilles spacing? For potential owners who planned to install, this must be taken note especially when getting different pricing on quotations. Big big spacing but cheap! Or smaller spacing but slightly more expensive. You pay what you get! Share this post Link to post Share on other sites
