• Weather Proof: Beats all weather conditions. Unlike Timber windows Alternative Frames do not absorb moisture and do not alter under extreme weather conditions.
• Anti-Fungi, Anti Termite: U-PVC is not vulnerable to insects and termites. Its hard surface compound protects it from such invasions, and it does not degenerate like wood.
• Maintenance Free: Alternative Frames do not require periodical repainting or maintenance. They do not rot, warp or corrode. This renders them more economical in long run.
• Thermal Insulators: The Alternative Frames design prevents thermal bridging making insulation extremely effective. It has the option of two layered vacuumed glass panes to achieve more from air conditioning and conserves energy. The system also eliminates the problem of water condensation on the window panes, inside the house.
• Acoustic Insulator: Protection against noise pollution and higher levels of privacy is ensured. Sound insulation is increasingly become a compliance issue in many sensitive areas including hospitals.
• Water Tightness: Joints tightness which is an inherent Alternative Frames feature keeps the driving rain out. Can also be used in certain special environment conditions like proximity to swimming pools/beaches. It has been used successfully in marine applications.
• Burglar Proof: Alternative Frames offer strong resistance against burglary. Expert installation of steel reinforced fittings and glazing reduces the treat considerably.
• Fire Resistant: U-PVC materials used in Alternative Frames are fire resistant and do not support or enhance accidental fires unlike their timber counterparts.
• Eco Friendly: Alternative Frames are energy efficient compared to other materials. The compound used is recyclable and as a stronger option to wood, they contribute effectively in drive against deforestation.

TECHNICAL SPECIFICATION

Excellent Heat Insulation, Energy Savings

In an air-conditioned building, windows with low thermal conductive material can reduce the loss of energy according to the fact at 37%. The intelligent selections on factors of thermal conductivity are the material of the window profile and the selection of the glass. The thermal conductivity of PVC is 0.13 kcal/m2 hr ºC and that is 1/1250 of aluminum which has 175 kcal/m2 hr ºC. PVC-U windows is 1.3 kcal/m2 hr º C while, the aluminum sliding window has 16.3 kcal/m2 hr ºC (the k values were obtained from actual windows).

For example, the K-value of PVC-U window having 6 mm glazing single pane is 4.5 kcal/m2 hr ºC while the K value of aluminum window having the same glass is 7.6 kcal/m 2hr ºC. Therefore, the PVC-U window can reduce the energy loss by over 30% and it is the best ENERGY SAVING WINDOW.

Excellent Sound Proof

PVC-U window material and the multi-chambered designed profile have tight seals, which are the best in noise reduction. An average sound separation of 22-25 dB is reached in 6 mm glazing and 30 dB in double-glazing. It brings tranquility and cuts unnecessary disturbance that is why it is especially favorable to be used in Hospitals, Schools and Office Buildings. Moreover, after a day of hard work, you deserve to go home with best protection from exterior noise.

Low Thermal Expansion

PVC-U windows are easily operated even under any weather conditions due to its low coefficient of thermal expansion (3x10-5/ºC/cm). During summer the out door temperature is 45ºC. The maximum thermal expansion then is 0.36 m/m for 1.5 meter of profile. During winter, the maximum thermal expansion is 0.9 m/m for 1.5 meter of profile.

Electricity Insulation

PVC-U has high electrical insulation which exceeds 1015 ohms-cm. It is absolutely safe from electrical conductivity and maintenance free.

Minimum Air Filtration

Impervious weather-stripping provides maximum seal. The experimental value per cracked meter length is 8 m3/hm2 for sliding window and 2m3/hm2 for casement. This low air infiltration serves to increase the efficiency of air-conditioner hence, SAVES ENERGY.

Excellent Fire Proof

The PVC-U material is an excellent fireproof material according to DIN 4102 for its non-spontaneous ignition and self-extinguishing characteristics. According to the result of window material combustion test with wood, aluminum and PVC-U conducted by Zurich Fire Brigade on February 16, 1973, the PVC-U window had been proved to have no damage and met the "stipulations of combustible building materials used in high rise buildings".

High Precision

PVC-U material could be processed precisely and the measurement of length, width has a tolerable value of +/- 3 mm.

Attractive Appearance

PVC-U windows has smooth surface and welded corners with optional color combinations (laminated or painted) which gives superior outlook.

Excellent Weather Resistance

PVC-U window profiles are specially formulated to achieve a high resistance against UV attacks. It can withstand long exposure in extreme weather change under scorching sun, storms, dryness and high humidity. No brattling and quality deterioration occurs after long term of usage.

Excellent Water Resistance

PVC-U as a material absorb water below 0.1% moreover, the uniquely designed weep holes and weather-stripping provide water resistance. Water infiltration test shows NO WATER LEAKAGE for 10 minutes with 4-liter/min. m2 at the wind load pressure difference of the rating tested.

Corrosion Resistance

PVC-U windows are free from the attack of acids, alkalis, waste gases and salts. It is corrosion resistant when used in Saudi Arabian environment with it's desert climate and high pollution exposure due to heavy industries. PVC-U windows have proved to be excellent and most preferred in industrial factories such as breweries, textile and paper mills.

Impact Resistance

PVC-U profiles are uniquely designed & specially formulated to withstand high impact. It has an impact resistance of 3 kg at 1m in height at 23 deg. C.
