![]() Choosing a subtle sky blue, bright turquoise or even a bronze tint can enhance the tones of nature in your design, all while creating a unique installation. Using tinted smart glass in roof design can enrich the natural colours of the sky. Now entire roofs are being created using smart glass technology. Smart glass uses have long since evolved from simple window applications. Installing a coloured smart glass window or screen demonstrates an incredible attention to detail, and allows every surface in the space to make an impact. Selecting a smart glass tint which is contrasting or complementary to your current colour scheme can be the ideal way to finish a project. Moreover, each individual panel can also have a patterned inter-layer installed, allowing each pane to serve as a stand-alone piece. Different colours can be chosen for each smart glass panel, allowing specific patterns to be created using the technology. Smart glass panels usually appears in one solid colour when in the opaque state but with colour customization this doesn’t need to be the case. The glass can be customized so that the branded colour tint is only visible when the privacy mode of the glass is selected. This allows businesses to display their pride in their brand, while also positioning themselves as creative and innovative market leaders. Customize the design with brand colours by integrating a smart glass tint on the most prominent glass surfaces. The colours available will vary from provider to provider, but one thing remains unanimous – the uses of tinted smart glass uses are as numerous as the benefits.Ī company’s office or retail space is a direct representation of their brand, and so should be styled as such. Switchable smart glass can also be combined with coloured inter-layers to meet bespoke requirements. Since it is highly customizable, it has a range of benefits for designers and enables incredible experimentation.ĭesigners aren’t just trialling the use of smart glass panels in different shapes and sizes. Our Safety Window Films are designed to hold broken glass in place and help prevent flying shards of glass from harming people and damaging property.Smart glass technology is rapidly gaining popularity in both commercial and residential interior design. These clear, single layer polyester films rely on thickness to provide additional security benefits. From break-and-enter crimes to accidents and natural disasters, Our Safety & Security Window Films provide precious time by helping to deter unwanted individuals from entering your home or business, protecting people and belongings. ![]() Significantly blocks the amount of harmful UV rays that cause fading, helping to extend the life of furnishings. ![]()
I don't think that we'll be back unless we want take-out. All I can say is that, for a restaurant in a nice neighborhood and a pretty regular clientele, they have really dropped the ball with regards to cleanliness in the one area that should be the cleanest, which then made me wonder about the rest of the place. ![]() The vent fan cover was caked in dust, and you heard a rather steady dripping noise coming from somewhere nearby. The room was very damp, with traces of rust on just about everything from the floor tile (which was rotting away in the corners). Chinese Restaurant 537 Green Bay Rd, Wilmette, IL, United States, Illinois (847) 251-7760 Closed now Price Range Rating 4. So, we weren't impressed, but then I went to visit their rest rooms and, quite frankly, I was appalled. The cashew shrimp were in a rather sweet plum sauce, the egg foo was rather meager and a little tough and the green beans, which are supposed to pack a little punch, were rather limp and watery, without much (if any) heat. The egg rolls were a little better-than-average, the hot sour soup was good (with the heat more from pepper than from vinegar) but, after those items, the rest were just OK. We had an appointment in downtown Wilmette and so, craving a good basic Chinese meal nearby, we thought we'd visit Tsing Tao.įirst, let me say that the service was quite good, friendly and attentive, and we'd ordered a meal consisting of "the basics" - egg roll, hot sour soup and a couple of entrees (veggie egg foo yung and cashew shrimp) along with a szechuan green bean plate, so our expectations were not that high (i.e., we didn't order anything super-authentic, except for perhaps the green beans). There's been a Chinese restaurant in this space for ages, and since moving back to the area, my wife and I have wanted to re-acquaint ourselves with the food scene, we thought that we'd revisit a place that we remembered from our childhoods in the.
