What does upvc stand for?
The plastic Poly Vinyl Chloride is commonly abbreviated to PVC. UPVC is Unplasticised Poly Vinyl Chloride and is a rigid form of PVC often used in the building industry as a low-maintenance material.

UPVC stands for Unplasticized Polyvinyl Chloride and used mainly in building materials such as doors and windows. It is generally used as a substitute for painted wood, most…ly for window frames and sills when installing double glazing in new buildings, or to replace older single-glazed windows. UPVC has also almost entirely replaced the use of cast iron for plumbing and drainage, being used for waste pipes, drainpipes, gutters and downspouts. uPVC is known as having strong resistance against chemicals, sunlight, and oxidation from water.
Yes, it is combustible.

The advantages of UPVC windows are that they are water/fire/weather resistant, which is extremely helpful. They also are environmentally friendly and economically friendly as… well.
Cut the pipe at right angles to its axis and to the required length. Deburr the cut end of the pipe and then chamfer the leading edge of the pipe at approximately 30° - 40°.… This will prevent the solvent cement being wiped from both the pipe and the fitting when pushed together. # Dry fit the pipe to the socket of the fittings. When the pipe is fully home in the socket, draw a line around the pipe at the edge of the socket. Where this is not possible, measure the socket depth and draw a line at the corresponding point along the pipe. This will give a visual indication to ensure that the pipe is fully home in the socket. # Roughen both the pipe surface up to the indicator mark and the inside of the socket with emery cloth, this will take off the shiny surface. # Do not roughen both surfaces of the pipe and fitting to the extent that the clearance between them is noticeably increased. # Degrease the surface of both the pipe and the fitting with a lint free cloth or piece of absorbent paper dampened with Effast MEK Cleaner. Ensure that both jointing surfaces are fully cleaned. Allow the cleaner to evaporate, before applying the solvent cement. Any excess cleaner should be quickly removed from the surface of the pipe or fitting as this may affect the integrity of the system. # Select the correct solvent cement. Do not attempt to solvent weld PVC-U Pipe and fittings with ABS cement or vice versa. ABS cement, will need to be thoroughly stirred before use, PVC does not. # Apply the solvent cement straight from the tin with a suitably sized brush. Ensure that the roughened area in the socket and pipe up to the visual indicator is completely covered with an even layer of cement. It is essential that the excessive use of solvent cement is avoided. This part of the procedure must be done quickly and neatly as the solvent cement must still be wet when the pipe and fitting is pushed together. # Push the pipe and fittings together and hold in place for up to 30 seconds for smaller diameter sizes (up to 2"/63mm) and up to 1 minute for larger sizes (2"/63mm - 12"/315mm). When the joint is made a bead of cement will form between the chamfer of the pipe and the central register of the fitting. This bead will help ensure the integrity of the seal. Excessive deposits inside the fittings must be avoided as this can weaken the wall especially on small sizes. A bead of solvent cement will also form around the outer joint of the pipe and socket. This excess cement should be wiped away leaving the outer part of the joint clean. Do not disturb the joint for 10 - 15 minutes. # After 8 hours under normal conditions the cement within the joint will have dried enough to be able to withstand the rated pressure of the pipe system, however, we would recommend leaving the joint for the full period of 24 hours wherever possible. Please note that all drying times in a pipe system only start on the completion of the last joint. After 24 hours the pipe system can be fully pressure tested. The test pressure should be equal to 1½ times the rated pressure of the lowest rated fitting or pipe within the system. # Please note that during the jointing procedure both solvent cements and cleaners produce vapors (fumes), therefore, we recommend that the jointing procedure should be undertaken in a well-ventilated area. We also recommend ventilation within the pipe system during assembly, to disperse any potentially harmful vapors.

uPVC actually stands for unplasticised polyvinyl chloride. uPVC is also commonly known as rigid PVC and it is called this because it is hard and does not flex. This material d…oesn't not contain any phthalates or BPA, so it is actually quite safe. uPVC is so stable and safe that it is actually used to make dental retainers and mouthguards!

Some of the disadvantages of UPVC windows is that they tend to discolor. Some turn yellow, white or even pink. Bad weather can cause cracking, expanding or warping to your UPV…C windows. It has been said that they are not as pretty on the eye.
UPVC cladding is moderately easy to fit because the joints are fabricated to fit the panels. UPVC cladding can be attached to brick, drywall and wood.
PVC is polyvinyl chloride. uPVC is unplasticized polyvinyl chloride.
uPVC or un-plasticized polyvinyl chloride is manufactured the same way as all PVC resin is. The process takes ethylene and reacts it with chlorine to form ethylene dichloride …(EDC). It is then reacted to form vinyl chloride monomer (VCM), which in turn is reacted to form Polyvinyl Chloride. (PVC).
