|General information about upvc,pvc,pvc-u and vinyl:
PVCu (or Vinyl if you are from the USA)
This is an excellent, highly insulate material, which benefits from little or no external maintenance. It is readily available and well tested and is usually the lowest cost option of all three materials. It is mainly seen in white but also available in Mahogany and Oak woodgrain styles. PVCu is by far the most popular material for windows and doors today.
There are many well-proven PVCu extrusions available. Problems with discoloration are virtually unheard of and most suppliers will warrant against this. The design of the windows varies from company to company. Here are a few of the main points. You may like to raise them with your supplier.
Internal or Externally glazed windows
Most PVCu systems will now give you this option. As a generalisation Internally beaded windows (where the glass is held in from the inside) are considered more secure and burglar resistant. That said there are a lot of satisfactory externally beaded PVCu systems about - many of which feature either internal wedge gaskets or a "double sided" tape which holds the external bead firmly in place. You should investigate this particular issue with your supplier.
Thickness of PVCu walling?
Most PVCu systems for window and door construction are "multi-walled" with internal reinforcement by means of either Aluminium or Galvanised Steel box section. Wall thickness can vary from system to system - most are around 3 - 3.5 mm thickness. Generally speaking the "thicker" the walling - the stronger the section. Ask your supplier for an example section and enquire if the frames are fully reinforced. Note also that the greater the number of internal walls - the greater the strength.
Polyvinyl chloride, (IUPAC Polychloroethene) commonly abbreviated PVC, is a widely-used plastic. In terms of revenue generated, it is one of the most valuable products of the chemical industry. Globally, over 50% of PVC manufactured is used in construction. As a building material, PVC is cheap and easy to assemble. In recent years, PVC has been replacing traditional building materials such as wood, concrete and clay in many areas. Despite appearing to be an ideal building material, concerns have been raised about the costs of PVC to the natural environment and human health.
There are many uses for PVC. As a hard plastic, it is used as vinyl siding, magnetic stripe cards, window profiles, gramophone records (which is the source of the name for vinyl records), pipe, plumbing and conduit fixtures. It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is used in clothing and upholstery, and to make flexible hoses and tubing, flooring, roofing membranes, and electrical cable insulation. The material is often used for pipelines in the water and sewer industries because of its inexpensive nature and flexibility.
In 1926, Waldo Semon of B.F. Goodrich developed a method to plasticize PVC by blending it with various additives. The result was a more flexible and more easily processed material that soon achieved widespread commercial use.
Due to environmental concerns use of PVC is discouraged by some local authorities and in countries such as Germany and The Netherlands.
By choosing vinyl over "traditional" building materials, there are also continued cost savings over the life of the home or building. Vinyl is virtually maintenance-free which means there is no worry about costly repairs, painting, or replacing the product just a few short years after installation.
There's a place for vinyl in nearly every project - as long as you require products that are easy-to-maintain, durable and attractive. Inherent in the vinyl manufacturing process is the ability to formulate products in virtually any color and with any number of performance qualities - including UV stabilization, flame retardance, impact resistance and flexibility - and in virtually any size, shape or thickness.
In outdoor applications such as siding, windows and fencing, vinyl has been subjected to demanding testing to make sure that it can endure exposure to hot sun, snow, hail and other weather conditions. Indoors, vinyl flooring and wall coverings are made to withstand regular foot traffic and spills and stains of all sorts. And behind the walls and underground, vinyl electric conduit and pipe resist corrosion and other damage, even in the toughest conditions.
Not only is vinyl durable and easy-to-maintain, but it is also inherently fire resistant. Vinyl typically resists ignition and limits flame spread, which could prevent a fire from starting or contain its scope. Like all carbon-based materials, however, vinyl will burn when exposed to certain conditions and should be installed according to local building codes.

Vinyl's environmental performance starts with the raw materials used to make it - mostly common salt, a practically unlimited natural resource. Production of vinyl requires a smaller amount of non-renewable petroleum resources than many alternative materials, while using significantly less energy.
In fact, one study indicates that the use of vinyl in eight major building and construction applications saves an estimated 260 trillion BTU of energy per year - the equivalent of 44.2 million barrels of oil. Vinyl's superior durability also saves resources, since it reduces the need for frequent replacement - and disposal - of worn-out products. And when used in window profiles, vinyl can save additional energy - and money - by efficiently insulating homes and buildings.
When vinyl building products do reach the end of their useful lives - or when vinyl scrap is generated at the construction site - the material can be recycled and reused in other building products, such as drainage pipe, windows, flooring, exterior accessories and fencing, or used in other applications, like traffic cones, parking stops or retaining walls. Programs are currently in operation to recycle vinyl building products.
