    Double glazed windows in Chiangmai

    thanks for taking the time to answer.    I had a look in CM   at a shop call Thai Conch ,  near Promenade.  salesperson was knowledgable.... products looked good.   Imported frames (upvc)were too expensive,  but chinese made uminim i would go with.   Still not cheap,  but hoping the noise reduction will be as you experience.   

    i am sure they will be cooler as well,   till the walls heat up  ????

     

    for all those who wonder.....   a 250 x 120  4 pane window  ( 2 inside panes slide open)  with mosq netting,   installed      around 17,000 baht          regular aluminum frame with single pane glass... around 3000 baht at local shop

    Thai Conch did my uPVC windows. Agree Salesperson is very knowledgeable and answers all question directly - or researchers and gets back to you.   Good follow up service also when i has some issues -  some glass wrong color , replaced quickly at no charge . For my next project I will use her to order my double glazed glass and do the wood frames myself. 

     

    RE the noise insulation - just make sure the noise will not enter elsewhere such as the soffits under the eaves , If you have only gypsum ceiling with no ceiling insulation the noise may enter through this way negating your double glazed efforts.  

     

    If you go with aluminum check the price of anodized aluminum. I've used anodized and 10 years later with direct afternoon sun they still look 100% like new -  and zero maintenance. 

     

    Good luck !

    Double glazed windows in Chiangmai

    in Chiang Mai

    I've installed double glazed windows on 2 houses in Chiang Mai.  Here is what I've learned that may help you decide ; 

     

    - glass was manufactured in BKK.  Good quality work. These companies  export worldwide so standards are good. Not had issues re condensation between panes in 10+ years 

    - very good noise insulation -  but make sure the 2 panes are different thickness -  ie 6mm and 5mm .  This reduces resonance of sound waves = better noise insulation . 

    - heat insulation - air gap of 10-12mm best . Argon gas inside air gap 'apparently' provides better insulation .  I've tried argon (B100/m2)  but really cant tell if it works.  Cant tell if the argon has even been injected or if it has leaked out over time.  But in theory, under test conditions ,  it works . Also apparently provides noise insulation   

    - heat insulation -  if you use aluminum frames with no thermal break - and you have direct sun exposure on the windows - you will get a lot of heat transfer through the frames and onto the inner pane of glass. Thermal break alu frames were expensive when i looked (imported)  and not very common here. Thermal break is  common in N Europe where you have temperature differentials of 60C or more.  In C Mai the differential is only 30C .  

    -  Better frames for insulation are wood or UPVC (many different qualities of PVC so choose carefully)  .  I've done alu with no thermal break, and UPVC.   Next I will try teak wood. You can look up the R value of these 3 and see alu is an excellent heat conductor!! 

    - Is it worth it ? For me the noise reduction is worth it .  The heat insulation will reduce electric bills - how much depends on the window  frames  and whether you have direct sun on the glass .

    Vaccination "sign up" at Big C Hangdong is useless

    in Chiang Mai

    Posted

    I went to Big C Hang Dong also to register-  today at 330pm. Appears to be 2 different registration booths  -  one for people with passports only and one for people with either the yellow tabian baan(house book ) or pink ID card ( both these  contain the 13 digit thai ID)  .  I had my yellow tabian baan and got an appointment at Bangkok Hopsital C Mai for July 7 at 700am -received a printed appointment document .  When i asked,  they said it was the AZ vaccine.

     

     My friend registered with his passport only  and was told he will receive an email with an appointment time and location .
