last time i did my yard windows (closed casket) type, the guy charge me rm18per sqft.. i did my survey and he was the cheapest...
other charges me rm20-25 sqft...

if u want sliding type, it should be cheaper...
i'll post down his number later.. i dont have it with me now...

contact person: mr khoo 0122131799
u can see the window spec at HOuz Depot Kota Damansara.
Got some samples for you to examine...both casket and sliding type...
If you buy through Houz Depot, the price will be slightly higher...
so cut the middleman, deal directly with supplier...cheaper...

my rm18 sqft casket window is normal aluminum frame with no tinted.. tempered glass... good for sunlight and drying wet clothes... black one tend to deflect heat and less sunlight... i'd give it an A for workmanship quality.. evrything is perfect...they charge same price although i asked for twin window (smaller ones on top so I can keep it open all the time).. other supplier charge me a bit more for this cos they say need to use extra aluminium for frame and handle bla bla bla....

no prob... i went through the same thing last time looking for the best deal..
at last, a salesperson in houz depot gave me this guys number, so I can deal directly with supplier to get cheaper price... lucky me..
