Frequently asked questions
What is PVC?
PVC or uPVC was first discovered in 1827 and was first used in making golf balls and heels for shoes and is now the second most produced plastic in the world. Most plastics do burn but modern PVC does not since it has a flame retardant chemical added when it’s being extruded. PVC is also a good material for window and door frames because scratches and light burns can be removed with light emery paper and oil. A course cleaning polish then gets the shine back. It is also ECO friendly: you won’t chop down a tree to make windows and doors or make a large hole in the ground to make an alloy frame. PVC is also usually designed to have natural light incorporation and thermal insulation which saves electricity from reduced usage of lights and airconditioning. Furthermore, due to its plastic nature, when combined with glass it cuts down to 80% of the external noise pollution.
What are PVC’s advantages and disadvantages in its windows and doors compared to steel and aluminum?
Steel windows which are on the shore line will only last a few years before rusting away. Have you ever seen old steel windows? After a few years, you try opening them and find the casement part is stuck to the fixed part. Have you ever tried to pull them out, they just come out in pieces as the rust has just eaten through them.
When it comes to aluminum doors and windows the wheels are the only things that actually secure the sash to the frame and there is usually a space between the sash and frame letting wind and rain inside, this also reduces the life of the rollers as the water will cause corrosion very quickly, whereas, PVC’s sashes overlap the frame by 10mm, where a brush eliminates the rest of the gaps.
The only disadvantage of PVC is the cost, since it is a much bigger sash and frame which helps eliminate sound and reduces heat because of the width of PVC frames and sashes, moreover, PVC cost more to extrude.
Customizable PVC windows and doors?
Just like all none pre-fabricated windows, PVC can be made to any size although there is a minimum practical size as it becomes difficult to weld the corners together. The smaller you make a window, the more you need the height-to-width on a sliding system to be able to make a good weld.
Other things you should know are max heights and widths: the standard height of doors are 2.1 meters and width around 0.9 meters. There are a few reasons for this, one is weight; another is as you go higher with sliding doors they get the shakes. 2.4 meter high sliding doors can be done as long as the right steel reinforcement is used in the sashes, now we are down to the sliding doors’ weight which leads to thinking about the thickness of the sliding doors’ glass
What are the different kinds of glasses to be used in the windows and doors?
1. 6mm ORDINARY GLASS has some effect in cutting down noise and heat but it is not the safest glass in the house as when in breaks it breaks into large pieces making it easy for a person or child to be cut.
2. 6mm clear TEMPERED GLASS is 4 times harder than the ORDINARY GLASS. In the event that it does break, it breaks into a lot of very small fragments still leaving possibilities to be cut but not as dangerous as the ORDINARY GLASS.
3. 6.72 LAMINATED which a uPVD plastic sheet sandwiched between two pieces of glass given it extra qualities like:
a. Extra Security: If someone tries to break your window or door, the uPVD film stays intact.
b. Extra Thermal Insulation: The uPVD plastic keeps out another 30% heat or cold.
c. UV Ray protection: The uPVC plastic has Ultra-Violet ray reflective qualities.
d. Extra Noise Reduction: External noise is cut down by a large factor.
4. We also have different COLORED GLASS:
a. Bronze to Bronze Reflective: *Bronze has the most benefits as its cuts out more of the heat.
b. Blue to Blue Reflective
c. Green to Green Reflective
d. Grey to Dark Grey
e. Frosted: For areas you want to hide
5. 10 TO 12MM GLASS for those area where you need added strength for security
What are the different kinds of PVC Window setups, their functionalities and benefits?
1. Casement Window
A window with a hinged sash that swings in or out like a door comprising either a side- hung, top-hung, or occasionally bottom-hung sash or a combination of these types, sometimes with fixed panels on one or more sides of the sash. In the USA these are usually opened using a crank, but in Europe they tend to use projection friction stays and espagnolette locking. Formerly, plain hinges were used with a casement stay. Handing applies to casement windows to determine direction of swing.
2. Horizontal Sliding Sash Window
Has two or more sashes that overlap slightly but slide horizontally within the frame.
3. Bay Window
A multi-panel window, with at least three panels set at different angles to create a protrusion from the wall line.
4. Fixed Window
A window that cannot be opened, whose function is limited to allowing light to enter. Clerestory windows are often fixed. Transom windows may be fixed or openable.
5. Double-Hung Sash Window
The traditional style of window in the USA and many other places, with two parts (sashes) that overlap slightly and slide up and down inside the frame. The two parts are not necessarily the same size. Nowadays, most new double-hung sash windows use spring balances to support the sashes, but traditionally, counterweights held in boxes either side of the window were used. These were and are attached to the sashes using pulleys of either braided cord or, later, purpose-made chain. Double-hung sash windows were traditionally often fitted with shutters. Sash windows may be fitted with simplex hinges which allow the window to be locked into hinges on one side, while the rope on the other site is detached, allowing the window to be opened for escape or cleaning.
6. Tilt and Slide Window
A window (more usually a door-sized window) where the sash tilts inwards at the top and then slides horizontally behind the fixed pane.
7. Tilt and Turn Window
A window which can either tilt inwards at the top or can open inwards hinged at the side.
8. Single-Hung Sash Window
One sash is movable (usually the bottom one) and the other fixed. This is the earlier form of sliding sash window, and is obviously also cheaper.
9. Awning Window
A window hinged at the top
What are the different kinds of PVC Door setups, their functionalities and benefits?
1. Casement/Swing Door
A swing door has special hinges that allow it to open either outwards or inwards, and is usually sprung to keep it closed. Saloon doors are a pair of lightweight swing doors often found in public bars. Saloon doors, also known as cafe doors, often use double action hinges, which will return the door to the center, regardless of which direction it is opened, due to the double action springs in the doors..
2. Sliding Door
A sliding glass door is a door made of glass that slides open and sometimes has a screen. Sliding glass doors are common in many houses, particularly as an entrance to the backyard. Such doors are also popular for use for the entrances to commercial structures.
3. French Door
A French door, also called a French window, is a door that has multiple windows (“lights”) set into it, the full length of the door. Traditional French doors are assembled from individual small pieces of glass and mullions. These doors are also known as true divided lite[sic] French doors. French doors made of double-pane glass (on exterior doors for insulation reasons) may have a decorative grille embedded between the panes, or may also be true divided lite French doors. The decorative grille may also be superimposed on top of single pane of glass in the door.
4. Bifold Door
A bifold door is door unit that has 2 to 4 sections, folding in pairs. The doors can open from either side for one pair, or fold off both sides for two pairs. Bifolds are most commonly made for closets, but may also be used as units between rooms.
5. Flush Door
A flush door is a completely smooth, panelled door. Flush doors are most commonly employed in the interior of a dwelling, although slightly more substantial versions are occasionally used as exterior doors, especially within hotels and other buildings containing many independent dwellings.
6. Louvre Door
A louvre door has fixed or movable wooden fins (often called slats or louvres) which permit open ventilation whilst preserving privacy and preventing the passage of light to the interior. Being relatively weak structures, they are most commonly used for wardrobes and drying rooms, where security is of less importance than good ventilation, although a very similar structure is commonly used to form window shutters.
7. Stable/Dutch Door
A stable door is divided in half horizontally. The top half can be opened to allow the horse to be fed, while the bottom half can be closed to keep the animal inside. Stable doors are also known as dutch doors.
8. Pet Door
A pet door is an opening in a door to allow pets to enter and exit without the main door being opened. It may be simply covered by a rubber flap or it may be an actual door hinged on the top that the pet can push through. Pet doors may be mounted in a sliding glass door as a new (permanent or temporary) panel. Pet doors may be unidirectional, only allowing pets to exit. Pet doors may be electronic, only allowing pets with a special electronic tag to enter.
Why choose PVCSDS?
Simply because we don’t like having someone emailing us saying that it’s a bad job unlike other PVC FABRICATORS. OF COURSE NOT EVERYTHING CAN BE 100%. SO IF THERE IS A PROBLEM, WE WILL BE BACK ASAP DEPENDING ON WHERE THE PROJECT IS; WHICH IS ANOTHER REASON WHY WE DON’T LET THE ITEMS AND PRODUCTS LEAVE OUR FACTORY UNTIL IT IS CHECKED SINCE IT WILL OBVIOUSLY COST THE COMPANY TO FOLLOW UP ON A JOB NOT DONE PROPERLY.
