Outward Turn Doors

1&2. Frame and sash
Frame and sash are formed by profile bars with valuable features of uPVC material, such as long life-span, anti - oxidation, no smearing under solar radiation or acid rain without requiring for periodical maintenance.
3. Rubber gasket
Anti-ageing specialized gasket system ensures the rooms are airtight and well insulated
4. Reinforced Steel
Thanks to combining with the 1.5-2mm thick reinforced steel installed in the vacant space of profile bar, these door sets have a good capacity of strengthening, no bending and suitable with projects requiring wide area of doors, windows and partitions.
5. Industrial welding joint
Using advanced thermal reinforcing technology and hydraulic pressing makes it effective to be tight and prevent cracks at the joints.
6. Aluminum bar and desiccant-dryers
So as to absorb the moisture inside the bar and make the glass always transparent, a box form aluminum bar with tiny holes on the surface which contains desiccant-dryers to absorb humidity inside the glazing unit.
7. Double glazing
Inert nitro gas filled inside double glazing unit reduces the transmission of sound and heat as well as electricity saving transference. The glass box is covered with a special transparent adhesive sealant, with the thickness of 10-15mm prevent the inert gas escape outside.
2. Advantages of Smartwindows
1. Heat insulation
Smartwindows is the comprehensive assembly of components such as uPVC profile, glazing box, gasket in order to get 1250 times better heat insulation compared with other products. In case the outside temperature is below 100C but the inside is another world, Smartwindows always keeps you room warm in winter but cool in summer and saves electricity when using air-conditioner.
2. Sound resistance
Smartwindows are designed with high combined structure and tight gasket in addition to enhance sound resistance in accordance with DIN 4109
3. Anti-ageing, non-deflection and shrinking
Profile bars are made of uPVC material; the combination between polymer plastic and other addictives (tensile impact, UV resistance, fire resistance) and the reinforced steel inside the profile protects the door from deflection or shrinking at the temperature from -300 to 700C in sunny, rainy or humid environment.
4. Fire resistance
Smartwindows are produced from Polymer plastic and fire-proof addictives. As a result, they do not disintegrate into other inflammable components, even at very high temperature. Even if it were subjected to a temperature of about 10000C from a blowlamp, uPVC profile would only be slightly distorted but not catch fire
5. Impingement resistance
At the temperature of -100C, using 1kg hammer weight to fall down from the height of 1 meter to the profile, it is not cracked. Its capacity of resisting wind resistance is very good as well.
6. Waterproof Super tightness.
The super-tight gasket system of Smartwindows has draining ditches to prevent water from infiltrating into your room in accordance with DIN 18055. Two layers of indecomposable gasket to be sealanted in two slits of sashes. Hence the air can intrude in your room under 4m3, which can help you save electric power when using air conditioner.
7. Anti-Oxidation
Dong A uPVC profile bars have excellent durability, anti-oxidation, indecomposable capacity and non-spotted when standing under radiant energy and acid rain.
8. Safe protection.
Smartwindows with the design is considered by using bolts, locks with high quality of steel and the splint be kept inside, safety glass that restrict to break into.
9. Comfortable designed easy to apply
Smartwindows use the profile that is easy to design following the dimension and the color is so convenient to make high aesthetics. Therefore, the application is easy
10. Strong features

11. Environmental protection.
Using Smartwindows means you are protecting the environment as well as protect the health of yourself and society.
12. The advantages of uPVC Smartwindows with steel reinforcement compared with other traditional doors are: Saving electric consumption when using air conditioner, no maintenance fee, smart bolts and locks, super-tightness, anti-ageing, non-deflection and shrinking

2. Structure of SmartWindows Doors and Windows
* Structure of profile bar
Produced from uPVC material and being the combination between PVC plastic resin and other additional materials (tensile impact, fire resistance, no disintegration into inflammable components even at high temperature), a profile bar is produced in box shape, divided into some vacant parts which have a 2-3mm thick wall so that it has excellent capacity of sound insulation and heat resistance. The profile bar is also put reinforce steal inside to strengthen the door. Profile bars are assembled with one another in order to make diversified type of door and window sets with suitable dimensions and styles for all kinds of architecture, from office buildings to hotels, apartments or villas.
