FAQ


UPVC, also known as Unplasticized Polyvinyl Chloride, is a low-maintenance building material used as a substitute for painted wood, mostly for window frames and sills when installing double glazing in new buildings, or to replace older single glazed windows. It has many other uses including fascia, and siding or weatherboarding. The same material has almost entirely replaced the use of cast iron for plumbing and drainage, being used for waste pipes, drain pipes, guttering and downpipes. These products are often referred to collectively in the home improvement industry as “Roofline“.
What is good to know, is that UPVC is a cheaper alternative to expensive hardwood timber and aluminium. It is a popular material due to its durability and it being a cost-effective option. It can also be known as PVC and PVCU.
The amazing strength, versatility and low maintenance comes from being manufactured using vinyl polymer which is bound to chlorine atoms so the window frames are not actually plastic and can work well with steel. This means that homeowners won’t have high ongoing costs.
Currently, all UPVC windows and doors must be energy rated to conform with the Building Regulations, and are available in choice of attractive colours and woodgrain timber effect finishes.
If you’re looking for energy efficiency, UPVC is the perfect choice, as energy rated UPVC windows are extremely thermally efficient. They have a very low thermal conductivity as a result of the type of materials used in manufacturing. This stops heat escaping as easily as it can do with some other building materials.
The main advantage of all high quality UPVC products is that they never need painting, plus the only maintenance they really tend to need is a wipe down with a damp cloth once every couple of years or so

PVC: PVC has the properties of a material that can be made as soft as rubber and as hard as any engineered plastic. This versatility of the PVC is developed by adding additives such as lubricants, pigments, plasticizers, processing aids, stabilizers etc., during the process of blending.
Stabilizer – Heat & Light: Since PVC cannot be processed due to its sensitive nature, heat stabilizers are added to improve the stability of PVC. Enough stabilizers are required to prevent the degradation of the base material during PVC processing. As windows are often subjected to harsh conditions of high temperatures, they should also take care of endurance of profile under continuous exposure to heat and UV.
Processing Aids: These acrylic based materials are generally the ones which enhance the melting strength during the fusion process. It contributes to smooth extrusion of the profile with uniform cross section.
Impact Modifier: Typically, polymers tend to become brittle once they are subjected to low temperatures or exposed to UV radiation. Acrylic based impact modifiers are used to retain their strength even after getting exposed to UV radiation or at low temperatures. The insufficient dosage or low-cost impact modifier (like CPE) may not be able to withstand the impact resistance over a long period of usage and may become brittle/ crack during fabrication, installation, operation or usage.
Lubricants: The use of these addictive is to manoeuvre the process-ability of PVC in the extrusion process. High usage or insufficient usage of the lubricants may cause product defect.
Pigments - Titanium Di-Oxide: Titanium Dioxide is an expensive material which is used as a white pigment, imparting natural white colour and provides the necessary UV stability for the product to have durability over years of usage. The amount of TiO2 used depends upon the UV radiation of the region. The pigment gives opacity to the product. Various pigments (organic/inorganic) & brighteners are used to color the dye but may not have similar UV stability. Cautious usage of this will ensure its weather resistance and color fastness. Fillers: Fillers are inorganic minerals (like calcium carbonate) as fine particles homogenized in the PVC blend. The padding affects the mechanical properties (such as tensile strength, elongation and impact strength), shrinkage and cost. When used in an appropriate proportion, it improves the mechanical strength of the polymer and if used in excess, though it reduces the price but impairs the durability of the product. uPVC has many advantages over other metals. Here are a few advantages listed down that makes it stand out of all the options available for you. 1.Low cost - uPVC is considerably cheaper than Hygienic and timber. Cost varies depending on the quality and features of the doors and windows. But you get the uPVC window at a much more affordable price. 2. Low maintenance - The material is popular because of its low maintenance feature. uPVC windows are extremely zero to low maintenance it does not lose its shine even after few decades. They can be easily cleaned using detergent and water without the requirement of any special oiling or cleaning like wood. Apart from, cleaning in and around the frames a few times a year, you can leave windows on their own. Unlike timber, iron or aluminum, you will not see any signs of rot, weather damage or rusting due to the incredibly durable nature of the material. 3. High performance - These windows are extensively energy efficient. Installing them helps to reduce heating costs and keeps you and your home fresh and warm. 4. Eco-Friendly - Besides being highly eco-friendly, it also helps in reducing deforestation. It is a smarter alternative for wood. uPVC is also highly energy efficient when compared to other materials. 5. Hazard Resistance - uPVC is a stable material which makes it sea-water resistant, pollution resistant and also chemical proof while naturally being flame retardant as well. 6. Sound Proofing - If you live in an area which has heavy traffic conditions, uPVC is the best option to opt for since, it provides excellent sound insulation and reduces outside noise by 70%. Due to urbanization and constantly increasing population noise pollution has become one of the serious issues in India. This kind of uproar is quite harmful for children, old age citizen and most importantly patience. uPVC windows reduce the sound up to 47 decibels and provide up to 62 per cent more sound isolation from other conventional windows which is not possible with other materials like wood or aluminum. 7. Hygienic - uPVC is highly hygienic. It keeps dust, pollens, wind, and bacteria out while closed. It doesn’t attract dirt which makes it easy to keep it clean. 8. Architectural Friendly - uPVC windows are made according to the shape and size. Due to its flexibility, it can be bent into any shape and size. This helps you to design your home according to your wish and not according to the standard rectangle or square shape of the windows which are widely available. 9. Highly Secure - With the increase of theft rates in the country it’s become very easy for criminals to break easy and ordinary windows. uPVC windows come with steel core construction which helps reinforce the structure. Combined with a sturdy lock, uPVC windows will be able to keep even the most determined of intruders at bay, all the while saving you tons of money. Due to its resilience, strength, and robustness, uPVC is also very reliable when it comes to home security. 10. Durability Unlike the traditional wooden and aluminum windows uPVC windows are extremely strong polymer with high tensile strength. Its quality of termite’s resistance makes it an excellent choice for the home. Plus, the life expectancy of uPVC windows are much higher as compare the other materials available in the market. Covering the most well-known reason, the sturdiness and longevity of uPVC is unchallenged. Known to be a popular choice for sewer pipes as well, uPVC can easily last 25 years. The quality is usually tested for ultraviolet radiance that cements its position as the number one choice for frames. 11. Energy efficient uPVC is a highly-insulated material that does not allow the transfer of heat very easily. This property allows you to keep your house cool during the summer and warm during the winter at a fraction of a cost. This way, uPVC helps you save a ton of money on your monthly electricity bill. 12. Cost-effective uPVC is relatively cheaper when compared to its counterparts like wood or metal. These materials cost at least 20% more than uPVC and require regular maintenance. On the other hand, uPVC is dirt cheap and does not require regular maintenance. 13.Temperature Control Due to its non-conductive properties, uPVC helps maintain a consistent temperature levels indoors. The frames do not transfer heat and they assist in moderating the temperatures accordingly. Working alongside double-glazed glass, both pair to form a set of energy-efficient windows that help regulate temperature inside while allowing in natural light. They are good insulating materials due to which, it keeps home warmer in winter and cooler houses in summer. It prevents thermal bridging so prevents condensation unlike aluminium. 14. Resistant & Insulated One of the biggest advantages of uPVC is that it doesn’t rot, and is resistant to corrosion that enhances its durability. Many coastal areas are known for their love for uPVC frames as it is resistant to salt-laden air. It is also known to assist with acoustic insulation. Double glazed uPVC windows and doors cut down noise by 50% to 70%. 15 .Recyclable Another major reason why use of uPVC is highly encouraged is due to its highly recyclable nature. Many high quality uPVC manufactures can easily be recycled to up to 10 times, with duration easily lasting a lifetime. This saves the material from reaching any landfills. The same off-cuts are sometimes recycled to make other uPVC materials highlighting its versatility and high usability. 16 . Secure Many businesses and homes are taking advantage of the tight closure that uPVC frames provide with its multiple point locking systems that create a stronghold for the window and keeps the interiors safe from any break-ins. Similarly, the windows and doors stay in place in light of heavy storms and rains, minimizing the risk of any damage 17. Fire Resistance uPVC materials are not prone to combustion in fact they are the profile compound possess a fire retardant rating according to DIN 4102 and along with it, it also fulfills Class 1 fire resistance as defined in BS 476. As mentioned above that uPVC has a strong layer of galvanized steel therefore, it is very difficult to break these uPVC doors and windows. This saves you from being victims of thieves and robbers, this is another added advantage. Disadvantages: 1. UPVC doors are unsuitable to be used as the front door as due to their light weight. 2. It doesn’t appear to be attractive due to its simple plastic look. However they are available in wide range of colours
Firstly, they are Low Maintenance. uPVC window and doors frames don't need painting or sealing which significantly reduces the maintenance required over their lifetime. It contains some very significant features like-
RESISTANT TO SALT EROSION
-uPVC is resistant to corrosion caused by salt-laden air making them ideal for coastal properties.
HIGH SECURITY
-uPVC windows incorporate multi-locking systems providing a high level of security for homes or businesses. Most uPVC window locking systems lock at multiple points all around the sash and frame.
RECYCLABLE
-uPVC can be recycled as often as 10 times. Although very little end-of-life uPVC windows are presently available for recycling in Australia, Australian industry programs are committed to keeping uPVC out of landfills, putting it back into new products. The off-cuts from uPVC window fabrication are already being collected in some states for recycling.
ACOUSTIC INSULATION
-Double glazed uPVC windows and doors are able to cut down noise by as much as 70%.
THERMAL COMFORT
-Unlike metals, uPVC is non-conductive meaning its use in window frames does not transfer heat and therefore contributes to a more consistent internal temperature for a building. The combination of uPVC window frames and double glazing makes for highly energy efficient windows.
TOUGH AND DURABLE
-uPVC is a very durable material used in water and sewer pipes for at least 100 years. Vinyl windows are so durable that the vast majority of them installed over the past 25 years are still in use. Good quality uPVC windows and doors are tested for ultraviolet resistance to ensure they won't fade in the harsh Australian sun.
ROT RESISTANT
-uPVC does not rot and is resistant to corrosion.
OPENABLE TILT AND TURN
-uPVC window systems allow for opening in two directions to enhance the ability of taking advantage of natural cross ventilation.
LOW MAINTENANCE
-uPVC window frames don't need painting or sealing which significantly reduces the maintenance required over their lifetime. They are easily cleaned with water and detergent.
BUSHFIRE PERFORMANCE
-Double glazed uPVC windows can be used in Australia in areas where risk is zoned as Bushfire Attack Level 29kW/m2 (BAL 29). Some uPVC windows have been tested to withstand BAL 40.
When you plan to buy uPVC window, there are a few important points you should consider carefully before making a decision, which are given below-
Selection of a right uPVC Profile and manufacturing department
-Selection of a right uPVC Profile plays a major role. We must consider the design of the profile but, most importantly, we need to understand the way it is manufactured and fitted. Good quality hinges and locks, well-engineered reinforcement used where necessary and the right screws in the right places, and the precise measurement of the window are the factors that play equally important part. How good the window looks and performs when fitted, depends on being fitted squarely with the right fixings and then sealed properly.
Attributes of good uPVC windows and doors
-The profile must not contain lead (which is toxic) as it is prohibited by EU, while profiles produced in India are not subjected to EU norms. So, in India, uPVC profiles are often contaminated with hazardous substance like lead. But PARIDA MACHINES didn't use this hazardous chemical. In our machines you will find “Titanium dioxide” provides the UV stability and therefore colorfastness for the white profile. This compound protects windows and doors from discoloring. But we use the right amount of Titanium.
Source of Origin plays a crucial role
-Source of origin is a major cause for price variation of uPVC window and door profiles. Our Profiles are produced in India and tested for the varied climatic conditions of the region for best performance, whereas some profiles that are imported are using compound that is suitable for the country they come from.
Window and door System
-All structure of uPVC system such as reinforcement, hardware, and accessories, are very important to extend the lifespan of uPVC window and door because they increase strength and durability. The system is designed to work as a whole and the windows should be well equipped with the correct reinforcement, mullion strengtheners and accessories, especially locking system. In case you have special need, for example, folding door, lift and slide door, or Tilt and Slide doors, you should check this quality.
Designing of the Windows and Doors
-Designing of window is way too important. Think how much opening you want in window …example with 2 panel design you may have 50%opening while with 3 panels 66%. But cost wise 3 panel is costlier than 2 panels. Also check if you need mosquito mesh provision. Glass specification also matters. For west facing windows tinted or low e glass is recommended, for road facing windows double sandwiched glass is good.
Secureness of the uPVC Windows and Doors
- The uPVC doors and windows are generally tempered and impact resistant. The high-grade tempered glass makes your uPVC doors and windows heat, wind, rain, and any sort of adverse climate resistant. The impact resistance quality of these windows makes sure they do not break under the force of burglars. These qualities ensure that your windows and your doors do not break in high external pressure and also that you are away from the burden of regular replacement.
uPVC is extensively used because it is not easily affected by climatic changes unlike other substances like wood and the best part about it is it lasts longer without any such prior repairs. The main points which proves it an ideal option are follows-
It is truly Fire-Resistant
- Fire tests have shown that uPVC materials, being naturally flame retardant through their product life, will not cause, support or enhance the natural development of fire. Unlike timber windows, the uPVC sections do not support combustion, and are in fact self-extinguishing. It has got an "A" class fire rating.
Resistant to corrosion and salt erosion
-It is totally Resistant to corrosion and salt erosion that makes them last longer than any of those doors and windows that are made up of wood. uPVC is non-conductive meaning its use in window frames does not transfer heat and therefore contributes to a more consistent internal temperature for a building.
It is Anti-Crowbar
- Most uPVC doors and windows are anti-crowbar, which means they cannot be forced open by an intruder in the way that traditional wooden doors and windows can be forced. And one more thing, uPVC has a strong layer of galvanized steel therefore it is very difficult to break these uPVC doors and windows this saves you from being victims of thieves and robbers.
Longer Life-Span
- The longevity of uPVC windows continues to be considerably more than their popular alternatives such as wooden and aluminium frames. Unlike their competitors, uPVC is incredibly weather resistant and will not allow damp to reach any further than the surface of the frame. Some of the most common window-related issues in the home include rotting and warping, commonly seen on wood, and rust which is the main culprit for damage in aluminium windows; all of which will not cause a problem when opting for uPVC, making it the most durable material available.
Little Maintenance Required
- As uPVC is resistant to rot, warping, rust and weather, little maintenance is required to ensure your windows remain in immaculate condition. Unlike timber frames which require regular specialist treatments and hardwood in which you will need to re-paint every few years, only cleaning will be necessary to ensure uPVC window stay looking brand new. It is recommended to ensure that uPVC windows are cleaned approximately four times a year. It is a quick and easy task that can be completed in minimal time.
Recyclable Material
- For those looking become eco-friendlier, opting for uPVC windows over alternative materials should be your first consideration. As uPVC is made from polyvinyl chloride, all frames are 100% recyclable and are incredibly easy to dispose of, making them ideal for both domestic and commercial use. It is thought that uPVC, as a material, can be recycled up to ten times without impacting its sustainability, durability and performance. This means that just one uPVC window can serve a life of up to even 400 years before it starts to lack performance.
External Noise Reduction
- Living in a busy city or town can often cause unwanted noise pollution and disturbance during unsociable hours of the night, which means that fitting effective installation is vital. Opting for a combination of uPVC window frames with double glazed glass can successfully lower external noise pollution up to 70%. Double glazing alone fitted to a frame in two or more layers is capable of cancelling out almost all sound frequencies, no matter the pitch or volume.
Saves Energy Costs
- Many are surprised with the idea that your choice in window material can have an influence on overall energy bills in both cold and warmer weather conditions. Windows are one of the biggest culprits for losing heat in the home. Double glazing alone is thought to reduce your energy bills by around £170; this thing is considerably increased with combined with the use of uPVC.
uPVC windows are largely beneficial in a variety of ways. Not only are they available in a large variety of styles, but they also happen to come with high-quality surface finish as well as soft contoured profiles.
Put aside the tools that will come in handy
-To make the overall process easier, you will need to make a list. Here are some of the things that you will need to keep handy:
- – Chisel
- – Drill
- – Screwdriver
- – Saw
- – Frame fixings
- – Door & frame sealant
- – Drill Bit
- – Tape measure
- – Heavy duty gloves
- – Light hammer
- – Pencil
Basic preparation
-You must understand and remember the fact that uPVC windows as a whole are not designed to be load bearing in any sense. Hence, you will need to make sure that there is an Intel above any window, before the removal process. Also, be sure to check the size of your window frame. The removal of any ornamentation or furnishing from the area surrounding the window is an absolute must.
The consultation process
-Once the site visit and assessment is done, you can be sure that the team will offer you the best-customized solution as well as listen to your added inputs about how to fix the problem. After all, this is a window installation process happening in your home.
Remove the existing window
-Firstly you will need to cover the surrounding areas with covers or durable dust sheets. Then, you will have to ensure that you remove all of the openers, inside the glass as well as the plastic seal, before applying the nail bar.
Fit the new window
-In this regard, you will need to make absolutely sure of the fact that every single aspect is taken care of systematically. This includes making sure that the sill is secured to the brickwork, using superglue to place the end caps securely, plus using plastic packers and ensuring that the framework is not bent.
The glazing process
-For this, you need to position glazing brides into the particular frame recess. This process is essential in order to ensure that no binding occurs within the locking system as well as preventing any movement between the glass and frame.
Ultimately, don’t get too overwhelmed with all of the steps. Sure, they may seem elongated, but at their core, they’re extremely simple to follow and implement.
Depends on how many windows per week you need to make, you can make PVC windows with as little as 2 machines (a saw and a welder) up to between 20 & 30 machines. Most of the bigger machines work off 3 phase electricity supply so that would need taken into account as well.
- 1. Cracked, chipped or broken glass
- 2. Water leaking through the frames
- 3. Draughty frame
