Frequently asked questions

"Polyvinyl chloride" (PVC) is a thermoplastic material, obtained from natural raw material at the end of several transformation stages. PVC is one of the most adaptable, cheapest and strongest plastic materials
Around 80% of PVC is used for long life products which last for between 15 and 100 years. These are building materials such as window frames, water distribution ans drainage pipes and electrical cable insulation and conduit. 10% of products are used between two and 15 years such as computer housing, car parts and furniture. Only 10% is used for less than two years and these include things that can only be used once like medical packaging. PVC packaging materials have a short life and most frequently end up as household refuse. On the whole, PVC is not designed to be wasted.
PVC is particularly fit from building & is highly appreciated by operators. PVC is generally used for pipes, canals, external coating, roofs, internal partition walls, Cable tubes, Panel doors, Windows, blinds and shutters. Its durations and economic and environment characteristics are very convincing reasons.
Technically, it is perfectly possible for Rajshri PVC to recycle and reproduce the original material. Scrap obtained during the production of door and window frames have long been introduced in to material production cycle even though they are not used for the production of main window profiles. All PVC remainders can be easily recycled with the same transformation procedure used to produce extrusions, with different uses and applications.
Aspects such as comfort, costs, the external aspects and appearance are strictly linked to doors and windows. External noise, energetic consumption, security, the desire to improve the apsect of the house etc....They all are aspects that render windows a fundamental factor of building. Rajshri PVC Doors guarantee high physical performances of a house acquire great significance in all these areas.
No, they are not. Even windows with a similar external aspect can be completely different inside. The quality of materail, its resistance, duration, the manufacturing process and the quality of the transformation process greatly differ, exactly like the structure of profiles and the tightness. In order to achieve the best products, Alphacan has always followed a high quality philosophy, paying great attention to the choice of the best raw materials, of innovative production systems and adequate controls on the products. The correct assembling and installation of the window is also a determining factor.

Doors made with Rajshri PVC sheet guarantee the highest effectiveness against fire. Rajshri PVC for doors hardly burns, in compliance with the regulation DIN 4102. BI. It is not prone to spontaneous ignition and does not burn if it does not come into direct contact with flames. It does not feed fires.
Rajshri offers a wide range of colours that meet all requirements. Mass colouring is white and sand (ivory), which do not need any kind of protective treatment, since PVC is particularly resistant against sun rays. Other colours, such as wood grain or dark colours, are obtained with the application of acrylic film on the sheets. These films are specifically studied for external use and are particularly strong against UV rays and bad weather conditions. The sun does not ruin this kind of product even after many years. Rajshri has been using these kinds of sheets since 1995 with great success and satisfaction on the part of customers.
Rajshri PVC Sheets, very thick and particularly resistant against impacts with their internal M.S. tube reinforcement, offer the highest durability with reference to frame and sash construction. It is clear however that the most important role is played by the hardware used (special closing system, reinforced with steel hooks and closing devices on each side), and of course the manufacturing and mounting of frames (application of accessories with reinforced screws inserted in the inner reinforcement of profiles and the installation made according to specify security criteria). All this guarantees the brand "high security door".
This is the field where the expression "Easy maintenance works" is particularly significant. An Rajshri Door, assembled by qualified installers does not need any special maintenance work, to guarantee its effectiveness and functionality. Sometimes it is necessary to oil the special closing hardware and the gaskets, in order to keep them efficient.
Yes, with the Rajshri door cladding sheet it is not necessary to remove the existing wooden structure, This is covered both inside and outside with specific sheet, designed for this purpose. Moreover, this frame can be mounted on all Rajshri cladding sheets, and therefore a wide range of solutions is available.
PVC frames have an unlimited duration. If normal maintenance work on hardware devices is made and if the surface is constantly cleaned from powder and smog, PVC frames can resist forever.
