Trade Secrets for Replacing Double Glazing Glass in PVC Windows

Most of the customers that I visit think that by having a broken or misted double glazed unit (glass) the whole frame needs to be replaced. Unless the frame itself has been damaged in a burglary or by accident the glass can be replaced without fitting a new frame.

Identifying the Glazing System:

The first thing to do is identify if the frame is externally or internally beaded. This is done by looking at the beads where they meet the inside edge of the window frame and identifying if there is a join there. Most new windows are internally glazed.

Removing the beads on internally beaded windows:

Insert a stiff putty knife into the join between the bead and the frame at the middle of the longest bead. You may need to push or tap the putty knife to separate the bead from the frame. Remove all of the beads one by one and the double glazed unit should be free to be removed and replaced.

Removing the Beads on Externally Beaded Windows:

There are a few different glazing systems on externally glazed windows. The most common one is the internal gasket or back wedge system. The rubber gasket on the inside of the window needs to be taken out to enable the external beads to be removed. To do this, take a stiff putty knife and press it into the rubber on the inside of the window and flick it out. Then follow the instructions for removing the beads above. Take note of which way the gasket comes out.

The next most common external glazing system is double sided security tape. The tape is put on to the window frame during manufacture and the double glazed unit is then pressed onto it, allowing the external beads to be clipped into place. Use a Stanley knife / Box cutter to cut the tape. Hold the knife flat to the glass to avoid slicing into the frame. Cut all round the taped area and you should be able to get the putty knife in and slowly lever the glass unit out. Once the glass has been taken out you can then get a scraper and remove all the old tape from the window frame, taking care not to damage the frame. Then follow the instructions for removing the beads above.

The third and least common type of glazing system is the sort that has no gasket or tape on the inside of the window. The beads on this type of frame can be removed from the outside with a putty knife. One word of caution With this type of frame, and some of the others. Some Externally glazed frames have Glass Locks fitted to them. Glass Locks are right angle pieces of metal that are inserted into special holder clips attached to the frame. If you remove the beads and see these metal clips, call a glazier as these clips can be very difficult to remove without the proper tools.

Measuring the Double Glazed Unit:

After removing the Double Glazed Unit it is advisable to take it to your local Glass Merchant for them measure it and check for any special coatings that the glass may have on it. If the Double Glazed Unit was sitting on plastic packers when you removed it, take them with you and ask the Glass Merchant if they are the correct packers for the job, if not, get the correct packers. This is very important as the cause of most Double Glazed Unit Breakdowns (misty / condensation between glass) is that they have not been fitted on the correct packers. If your window is glazed on security tape you will need to buy some new double sided security tape.

Re-Fitting an Internally Glazed Double Glazed Unit:

Make sure the unit is square in the frame and you have it sitting on your two packers. Fit the two shortest beads first by tapping the in with a nylon mallet. Then fit the two longest beads in the same way. You may need to push one end of the bead into position and bend the bead to get the other end in.

Re-Fitting an Externally Glazed Double Glazed Unit:

Back gasket system – Fit the glass and beads as described above and then push the rubber gasket back into the frame on the inside of the window. If the rubbers have shrunk you can gently stretch then out and re-fit them with a small blob of superglue in each corner to stop them from shrinking back again.

Security tape system – Fit the new tape to your window frame, taking care to keep it flush with the frame edge. Remove the covering and Spray the tape with window cleaner. This will allow you to move and align the Double Glazed Unit. The window cleaner will evaporate in a couple of hours leaving you with a Double Glazed Unit that can only be removed by cutting it out from the inside. Fit the glass and beads as described above.

One word of caution: Some Externally glazed frames have Glass Locks fitted to them. Glass Locks are right angle pieces of metal that are inserted into special holder clips attached to the frame. If you remove the beads and see these metal clips, call a glazier as these clips can be very difficult to remove without the proper tools.

If you are not sure which system you have or are not confident enough to proceed with the job, call a glazier. It will be cheaper in the long run to get someone who knows what they are doing than destroying your windows.

Which Tools Locksmith Uses

Locksmithing is a skilled trade, incorporating metalworking; lock picking, technological skills and even some basic carpentry. A locksmith today serves a couple of different purposes and has a number of job opportunities open to them. They make keys and change locks for homes and businesses. In addition, though, they often specialize in the installation of high quality locks and the design of improved locking mechanisms.

Locksmith uses special lock pick tools. These lock picking tools are proving very popular with puzzle clubs etc. But not only locksmith uses these tools, recently landlords who have tenants who have lost their keys are becoming big buyers of lock pick sets because they save money on having to call out a locksmith who will probably pick the lock anyway.

The basic tools for lock picking consists generally of the following special locksmith tools. Starting with manual picks, tension wrenches, key turners and lever picks. For professional locksmiths there are special destructive opening tools such as the special cylinder crackers and the bell, but also grinders and milling machines with grinding bits and discs, or cutting burrs.

There are many types of keyway and many tools to help. UPVC and Euro lock picking is easy with the slim line lock pick sets which are narrower than the standard versions allowing you better access to the pins inside the keyway.

The destructive tools are gathered under the term pulling and cracking devices for doors. For the optimal locksmith operation there is a set which contains special tools such as the bell with pulling screws. This so-called bell is especially developed for cracking the door lock cylinder. For doors a very important thing is a good selection of wedges. The air wedge slips between the door and the door frame and locksmith just pump it up and that expands and allows his tool to reach inside.

And what about cars? Opening cars has never been easier with the air fighter pro. A bag that slides between the door frame and inflates to all you to use one of the three tools (included) that will pop the locks or grab the car keys locked inside the car. Moving on to some of the other lockout tools you’ve got what all locksmiths know, a lasso tool. It allows to go in on some of the older cars. Those are the cars that have upright door locks and lasso the lock and just pull it up. Japanese tool comes up on the window and allows locksmith to work with the thumb style locks. The auto buster is really good for GM side locks where you slide down inside the window, come up on the inside and actually manipulates the sliding locks.

Often you’ll see locksmiths try to pick the lock with tools described below before they resort to other actions. Plug spinners are a great tool if client has picked the lock the wrong way and doesn’t want to have to pick the lock again. Pick guns and electric lock picks (usually 3v and 4.5v) are an easy way of picking a lock quickly. Warded locks and wafer locks are also pickable by using the wafer lock pick and the warded lock pick. Locksmith can also try the slimline euro lock pick tools.

Maintenance and Repair of UPVC Windows

UPVC is a very durable material and with proper maintenance and repair can have a life in excess of 20-25 years. Compared to products such as timber windows, UPVC windows, be they double-glazed or triple-glazed, do not need high volumes of time consuming maintenance and painting / treatment. Simple twice-yearly cleaning and inspection and quarterly lubrication is most likely adequate for these windows.

  • In broad general terms, any part of the window that is visible when the windows are closed should receive a wash twice yearly. This can be done with a warm soapy solution, taking care not to use abrasive materials such as scouring pads, or abrasive cleaning solutions such as ammonia based cleansers. It is always a good idea to remove such items as jewellery and watches, before commencing cleaning work on PVC-u windows as this avoids unnecessary damage (to the jewellery and to the windows!).
  • There are also the options of installing windows with self-cleaning glass, such as ‘St. Gobain Bio Clean’ and ‘Piklington Activ’.
  • When the windows are open, the remaining parts that you can then see should receive a wipe to remove dead insects, cobwebs, old oil or lubricants. The use of a vacuum cleaner can be helpful in these situations.
  • Always keep any drainage holes clear as this will ensure that any build up of condensation inside will be removed.
  • All hinges and locking points should be kept clean. As with any metal moving mechanism, regular application of a light lubricant oil will help to keep these parts in good working order. WD-40 spray is ideal for such tasks. A light application of a product such as petroleum jelly to hinges and moving parts after lubrication will help ensure their protection. Perhaps avoid heavier grease lubricants and avoid too much application that can result in grease oozing to the frames. It is always a good idea while cleaning to check the tightness of any visible screws at this time.
  • Clean the gaskets, weather strips and seals regularly with mild non-abrasive detergents. While you are cleaning, inspect to ensure that all seals remain correctly fitted to the frames. Many gaskets and seals can be removed and replaced without the complete removal of the window. If seals or gaskets do need to be repaired, the task should probably be carried out by a trained maintenance person.
  • If your frames suffer a small mark or scratch, repair kits can be available, however it is best to avoid damage of the frames, as larger marks cannot be repaired.

Lock Picking Tools Are Not Just For Burglars

We often see people in movies picking locks using everyday objects, a hair clip for example, a credit card or even a filament from a light bulb. Lock picking is often associated with criminal activity. People who want to learn how to pick a lock should only consider using it in an emergency.

People who have the legal right to pick locks are called Locksmiths, people who have the essential tools and know how to pick locks. Lock picking tools are essentially tools that are use to pick the lock. These tools have several categories and can be sum up into three categories, the Tension tools, Pin/Tumbler and Wafer picks, and Pick guns.

One category of these is tension tools. These tools are often referred to as torsion tools or sometimes called torsion wrenches which are basically ? shaped tools. The ? shaped tool is used to push the pins up. Torsion tools are inserted into the lock to deliver tension to the lock. This tools are the most commonly use and may take a while to master.

Wafer and Pin or Tumbler picks is another category of tools that are use to pick locks. These lock picking tools are specifically designed for wafer and pin or tumbler locks which are widely use in UK and North America. These tools are commonly sold in sets which contain a torsion wrench, picks ranging from warded or rake picks, up to half-diamond, slagel and hook picks.

A set is composed of 9 up to 32 pieces, every piece has it own unique function. Warded picks or more commonly known as skeleton keys are used to open a lock that uses a common shape key. The rake pick is used to rake the pins inside the lock. The Half-diamond is used for pin locks, the slagel are best for electronically close locks meanwhile the hook is for traditional/common locks.

The last known category of lock picking tools is called pick guns. There are two types of pick gun the electronic and manual. The manual have a trigger that goes up and down that make the pins jump inside the lock. The manual pick gun requires a good timing and most preferred by locksmiths. The electronic pick gun vibrates to imitate the lock picking method of the manual lock picking. The pick gun is a very tool to master, master the timing and let the pick gun to all the work.
