High UV effects on uPVC Window profiles – #DIMEX


High UV effects on uPVC Window profiles

India is High UV Sensitive Country
As windows are exposed to all harsh & extreme weathers, it is important that these uPVC windows can sustain the High UV radiations in India. India is a High UV sensitive country.
In the High UV regions as illustrated in the map , the uPVc profiles are likely to change colours get yellow & greyish brown won’t look nice. It can happen if they are not formulated with enough portions of UV stabilizers & Titanium Dioxide(TiO2). These additives are very expensive compared to PVC raisins and Calcium Carbonate /filler . The low grade & unbranded profile making companies especially from china save on these in order to sell cheap in Indian markets . The new entrants in the industry use such profiles without knowing its implications , which is a matter of great concern.
When you buy upvc windows, it is recommended to talk about this with your vendor and have this clarified and assured that profiles he uses can withstand the High UV radiations. The TiO2 used in the formulation is 8 parts and more ( like in #DIMEX_Profiles) & he/she provides a third party accredited Lab test report.
DIMEX Provide:
  • Cipet Test report with every sale CIPET – Central Institute of Plastics Engineering & Technology- A Government of India undertaking
  • 8000 Hrs UV retardent test report especially for India & Australia from Dimex .Most of the other companies provide usual test reports only for 6000 hrs.

Wind Resistance (Factor C) – #DIMEX

Wind Resistance-#Dimex

Wind Resistance (Factor C)

This test measures the wind pressure windows can withstand without suffering breakage (structural shattering) or permanent damage (structural deformation).

110 mph (175kph) C1 Low-end
125 mph (200kph) C2 Mid-range
155 mph (250kph) C3 High-end
180 mph (285kph) C4 High-end
200 mph (320kph) C5 High-end

220 mph (350kph) C5+               DIMEX
fixed, hung , and awning windows

Water Resistance (Factor B) – #DIMEX


Water Resistance (Factor B)

Watertightness is measured by projecting the equivalent of 20 liters of water per hour per square foot of window surface, the equivalent of 8 in. (200 mm) of rain in 1 hour. Air pressure is increased to simulate winds varying between 35 and 76 mph (57 to 123 kph). Ratings indicate the pressure attained without any interior water leakage, Using High Quality EPDM content sealing Gaskets.

150 pascals-3.0psf B1 Low-end  
200 pascals-4.2psf B2 Mid-range  
300 pascals-6.3psf B3 High-end DIMEX system

Air Resistance (Factor A) – #DIMEX

Air Resistance -#Dimex
Air Resistance (Factor A)

Air tightness is measured by applying 75 pascals of pressure–the equivalent of a steady 25 mph (34 kph) wind–to the outside of the window. Interior air infiltration is then measured in cubic feet per minute per foot of window joint.

0.5 cu. ft./min/joint ft. A1 Low-end
0.3 cu. ft./min/joint ft. A2 Mid-range
0.1 cu. ft./min./joint ft. A3 High-end
0.086 cu. ft./min/joint ft. A3+ Dimex sliding   and hung windows
0.002 cu. ft./min/joint ft. A3++ Dimex fixed &casement and awning windows

Forced Entry – #DIMEX


Here`s the proof (Air resistance, water resistance and more..)

This test reproduces the efforts of a well-equipped individual attempting to force entry. The test has three phases. Testers begin by trying to force open the window using tools like a knife blade, screwdriver and wire. They then attach a cable to strategic points on the window and apply increasing loads. If the window continues to resist, they use tools again in a third attempt.

Windows rated F1 have a locking system, but have not been tested for forced entry.

Windows rated F2 have successfully passed the test at level 10. DIMEX system windows are rated F2, level 40.

A Parallel to the window from the handle  
B Perpendicular to window from the handle,first by pulling, then by pushing
C Parallel to the window at center of the sash,from bottom upward
D Perpendicular to the window where sashes meet,toward the interior
F1 Test not required
Level indicates the initial load applied to the cables:
F2 Level 10 = 150 lb. Mid-range
Level 20 = 200 lb. Mid-range
Level 30 = 250 lb. High end
Level 40 = 300lb. Dimex system
