Too many Windows / Light?
Comments (41)Hi Chris Just following up your request for further info between double glazing and/ or filming single glazing Etc Your more than welcome to call me direct here in Tassy for a more detailed info. that’s not possible via this comments section . But just to highlight a few things for all interested readers . Firstly , it’s important to understand the “ Technical” differences between both single & double glazing ( particularly the different types of additives/ manufacturing processes etc that’s goes into making glass that can make a difference to how they perform technically and the ability to do what you want it to do and then theirs the choice of aftermarket window films . Whether the choice of an aftermarket window film application is considered to either single or double glazing to solve one or more problems, one must understand the pros and cons as to the window film manufacturers guide lines and their recommendations as to what type of film should be used or avoided considering the different window components and the different types of glass that goes into making the final window product . Secondly ; and equally important ; one must understand the differences between radiant heat and convection heat . Unless the glass is specially treated at the glass manufacturers or has an added solar film coating applied ( such as suitable window film ) when compared to clear glass and whether as a single glazed or a double glazed unit ; will NOT stop all the direct RADIANT heat through the glazing . Double glazing , or even triple glazing , works on the same principle like a thermos flask ; to reduce / slow down the transfer of CONVECTION currents ( hot or cold air temperatures ) from one side to the other . Radiant heat and convection heat are two different things and requires different ways to solve the problems . Double glazing is designed to reduce “convection” air temperature from moving from one side to the other , of the window . Other additional manufacturing processes can improve both insulation and heat reduction abilities . You mentioned a ceramic film and the infra red ( heat component ) reduction. I was wondering why a ceramic film was mentioned compared to say either a semi or fully reflective film choice !!!! Don’t get confused with all the advertising thats on offer via sales reps pushing their product as being better than other film options unless you fully understand both the advantages and disadvantages. One must compare apples with apples when comparing any technical data as many companies don’t all stick to a common standard tech specs making it difficult for customers to compare and often confused . The two main considerations when choosing a film ; particularly when double glazing is installed ; is the :- total solar energy reduction ( SER) and secondly the amount of absorption of heat ( SEA ) into the glazing . These are the two main factors I look at when heat transmission is a problem for a customer . The SER is the amount of the overall reflected away from the glazing and the SEA is the amount that’s is absorbed into glazing ( glass ) as this will effect how much increase in the overall temperature of the glass Particularly the panel which is tinted in a double glazing application which is normally the room side . The main problem if the glass temperature increases , it will increase the chance of glass breaking due to thermal stress .( gets too hot it will eventually break ) . One also has to take into account the quality of the glass , particularly most being made in Asia now .where quality may be an issue compared to Australian made glass .!!! Basically You need high SER with the lower SEA as an ideal choice . From my experience with over 40 years in the window tinting industry here in Tasmania that the fully reflective film I often use ; particularly on double glazing ; is a number one choice ; then secondly the less reflective MEP films neutral based film either in the suggested medium grade as generally the two films the manufacturers suggest in their guide lines As single glazing goes , between the full reflective or secondly the darker neutral ( a cross between the medium neutral and full reflective films ) I’d be interested in see the data on the ceramic film choice for me to compare to out of interest . The three films I’ve mention are by no means the only choices but many other factors comes into play that need to be taken into consideration . Much more on the subject but hope this may offer some interest to discuss further . Protek window tinting & blinds (Tas)...See MoreHow can I incorporate minimalist extension to a 100 year old home?
Comments (44)Hi RePete, another app for drafting is Home Sweet Home which is free. My experience has been that some of the really good architects are happy to share their ideas when they visit as they enjoy the creative process so much. Eg Williams Burton met with us years ago (we are still figuring out what to do!) - and I was very impressed. We didn't use them as they are very fastidious so their builds take a long time and we can't cope with that but they do some amazing work on character homes in particular and although people think of them as only doing very expensive jobs, I am aware that they have also done some cheaper jobs where the project has got their interest. You could try talking to them and a few others from that "tier". I can't remember if we paid for the initial meeting, but if we did it was only a very small amount. I would seek as many views as possible (including here), keep trawling the net and pinterest as well as Houzz, look at lots of magazines etc, go to every open home that is vaguely like your style and ask the real estate agent who designed/built it... (hmmmm this is why we haven't started building yet after 8 years...) As Ok says, probably the only person that can determine what accommodation is required is you, so make that thought process a parallel one to looking at pictures. Good luck....See MoreNeed to replace windows in new apartment - help!
Comments (6)Hi Damster Damster. Anything that insulates against thermal transfer will also insulate against noise disturbances. A good double glazed window with an insulated frame and a high performance seal should reduce noise coming across the window by 60% or more. A uPVC frame will give you the best performance and will last the longest. But, it can be tricky to tell which uPVC supplier is the best to go with. I'd be very happy to give you a hand with advice or arranging a quote for uPVC windows and sliding doors. At Enertec Window & Door Systems, we make custom built double glazed uPVC windows and doors. We've helped many apartment or unit owners upgrade their windows in accordance with the requirements of their body corporate. Give me a call: Gabrielle 0411 349 311 or shoot me an email gabrielle.enertec@gmail.com. I'd be very happy to assist! www.enertecwindows.com.au...See MoreFailed Basix due to large windows
Comments (18)I'm not expert, & no very little about the rating systems. But have heard they're pretty opaque, & as mentioned may not really mirror real world outcomes. I'm surprised that overglazing the northside will result in too much heat loss. If anything, with the right sized eaves, I'd expect it means too much heat gain in winter (& shaded in summer) in the day. But as mentioned by Paul, it's important that you have thermal mass within the home, to absorb this heat. Which can then be released over time as the home is cooling down in the evenings. Thermal mass are heavy materials, like masonry, concrete, & even water. By absorbing heat, & releasing it slowly, thermal mass knocks off the peaks of daytime highs, & nighttime lows, keeping the internal temperature more stable. Without it a lightweight home can become too hot in the day (even in winter on occasions) & too cold at night. Thermal mass is especially important inland, where the difference between daytime highs & nighttime lows (called the diurnal temperature) is greater. So if you are away from the coast of definitely investigate whether you have enough thermal mass in your home. A north facing concrete of tiled floor will do it. It will greatly increase the comfort & energy efficiency of your home. Instead of aiming for the bare minimum when it comes to energy efficiency, resulting in less comfort, & much higher bills. More about thermal mass can be found on this wonderful government website, http://yourhome.gov.au/passive-design/thermal-mass...See MoreIkonografik Design
