Our Lumei is only using high quality raw materials. The elements are based on profiles and high quality fittings. The profiles are of a special tropical formulation with a high concentration of Titanium Dioxide (TiO2), which prevent decolourisation due to UV radiation. The Glass is high quality thermal glass. Gaskets are of Neoprene (EPDM) a thermally stable elastomer, totally resistant to UV radiation and the tropical climate in the Middle East.
Our products:casement 60/65/70 mm;sliding series 60/80/88mm.
Lumei's profile had the advantages as follows:
(1)Good Water Sealing Property for extruded PVC plastic profile
With rain-proof plates, grooves, and poles water drainage, doors and windows can isolate rain outdoors completely.
It is in accordance with the regulations of DIDDN18055.
(2)Aging Resisting about extruded PVC plastic profile
Adopting imported improver, and with ultraviolet-radiation-proof absorbent, plastic doors and windows remain the same color and without aging under burning sun, heavy rain, dryness, and wetness from minus 30 degrees to 70 degrees.
(3)Fire Proof Property about extruded PVC plastic profile
The plastic does not self-ignite, does not support combustion, and can self-extinguish.
(4)Air-tightness
There are sealed strips on the gaps of joints, which can save energy.
(5)Easy Maintained
The PVC profiles will not be influenced by dust, cement, agglutinant, etc. They can be cleaned by any cleaning agent.
The superior performance of the Lumei profile:
1. Upgrade of health;
2. Upgrade of energy conservation;
3. Upgrade of service life;
4. Upgrade of strength;
5. Upgrade of colors;
- The Classic works of sliding windows, all adopt a flat design, with a smooth appearance and a complete range of supporting profiles.
- Various fixed frames, corners, reinforced splicing materials, etc. are all available. The large glass installation space can be used to install glass with different specifications.
- The specially structured cavity and European standard hardware installation slot facilitate the use of special rollers and high-end locks for sliding doors.
- The drainage cavity is designed on the outside and is separated from the other functions cavities to avoid mutual penetration.
- High yield rate, rich window types, moderate price, and simple production method.
- High wind pressure resistance and fully suitable for buildings with about 10-25 floors.
