Browse Forums Windows & Doors Re: New Construction - Double Glazing 70sqm variation cost 2 20May 22, 2018 8:36 pm ECOECO skyzdlimit I just got a detailed quote today from the builder but the breakdown is not for cost rather the window/sliding door specs..overall cost is $27400 for 30 Windows (70sqm of glass and upgraded frames) I have been provided with 4mm/10mm/4mm double glazing using 18mm dgu. I was told that it's a good spec for residential purpose. I have been quoted a mix of clear float and clear toughened glass. I was wondering why not all be toughened instead of float as toughened is more stronger and heat resistant. Does anyone know the cost/sqm to upgrade from float to toughened? $8-10/sqm? I was also thinking if I should upgrade to a thicker glass say 5mm or 6mm. Again not sure how much per sqm for the upgrade from 4 to 6mm. $25-30 per sqm? Appreciate your responses. Thanks. Regards, Kurshid
This is on the high side for the windows as a total cost, and I am not talking upgrade. Upgrade of $15k would be in the ballpark. [/li] [/ul] I felt that the cost is high as well, but I am interested in the cost that needs to be factored in for the single glazing that would have been allowed in the base price. I checked with the builder and he reckons its between 10 and 12k they estimated for the single glazing, builders range aluminium windows and sliding doors for 36 sq DB house. I was atleast hoping for 14k difference, so we can meet halfway. My upgraded window and door schedule is below; Window sizes are as follows; All are aluminium awning windows and have frame thickness of 55mm and double glazed (4/104 using 18mm DGU argon filled gap) except for the fixed glasses with different glazing and frame thickness
Sliding Doors sizes as follows; All sliding doors double glazed (4/10/4 , using 18mm DGU argon filled gap)
So the overall cost of the above windows and sliding door (approx 70 sqm of glass) comes to $27400 inc GST, of which the builder is absorbing roughly $10 to 12k leaving me with a difference of approx $15400 to $17400. Is $17.5k a reasonable upgrade price to to go from single glazed builders range aluminium window (frame thickness: 38mm), sliding door (frame thickness: 80mm) to double glazed and upgraded frame size (min. 55mm for windows and min. 101mm for door) as above? if not how much would be a reasonable upgrade to pay? Appreciate your response, as it would help me with a win - win outcome which is usually rare when you are not owner building. lol. Regards, Kurshid.
