Double glazing beading on the outside?!?

[Commander Kinsey]

Why do some glaziers fit the beading on the outside of windows? Surely, common sense tells us to put the part you can easily remove on the inside, for security.

[Andy Bennet]

Windows and doors may be glazed internally or externally.

Internal glazing means that the glass units are installed with glazing beads inserted into the frames from the inside.

External glazing means that the glass units are installed with glazing beads inserted into the frames from the outside.

Both are equally secure, provided either security tape or glass locks are installed, with external beading.

[Commander Kinsey]

How can external beading be secure? The burglar just does the reverse of what the installer did. I've done it to my own and my neighbour's windows very easily. Them because they locked themselves out, mine so I could get a sofa into the house which wouldn't fit through the stupidly narrow hall.

What is "security tape" - the word tape makes me think it's easily removed.

What are "glass locks"? Surely just put the beading on the inside, then you don't need whatever those are.

[Andy Bennet]

Externally glazed widows tend to have thinner frames and look more aesthetically pleasing rather than the thick framed internally beaded units.

Internally beaded widows can be easily kicked in. Modern externally glazed windows have security tape (double sided tape with a rubber filler)_ on the iside of the glass securing it to the frame. This makes is virtually impossible to remove the glass from the outside even after removing the beads. You need inside access to prise away the glass from the tape.

Granted older type glazing from the 70's and 80's was externally beaded but did not have security measures fitted.

Any house is a piece of piss to break in to if you put your mind to it, it's just a question of difficulty.

[Commander Kinsey]

That's noisy. I can get into a window with external beading silently.

[Commander Kinsey]

I don't see why, they're just fitted the other way round.

The amount of force to remove the beading on glazing I've seen would be more than that to break the glass.

Mine is as such, but was fitted in 2010.

Yip, I cracked the glass when I broke into my neighbour's house. External beading but difficult to get out (old and perished plastic - I think fitted about 2000). Didn't stop me gaining access, but I did damage their glass. I was trying to get in to let them in after they locked themselves out.

[Steve Walker]

Properly installed, older type glazing, without security tape, was not that insecure. When the external beading was clipped in, the glass was still loose. The glass was clamped into place (also jamming the external beading tight against the frame) by tapping (quite hard) a rubber seal between the glass and the inner frame.

It seems a common way at the moment is melting part of the frame to remove the glazing.

Mine was installed in 2005, I removed (and successfully and neatly replaced) the external beading, entirely from the outside, to remove the glass to get a sofa into the house. 5 minutes and a small screwdriver was all that was required. I made no noise at all.

Good idea. I was thinking a multitool, but that's loud.

What really amuses me is PVC doors with 7 point locks. But you can just put your foot through the PVC panel....

[Commander Kinsey]

Nowhere near as quiet. You still make a bang, even if you can muffle the shattering noise. And the only tool you need? A small screwdriver.

[Fredxx]

Most glaziers use silicone sealant to stick the glass to the frame. It doesn't matter which side the beading is, no manner of levering will get the glass out in one piece.

[Commander Kinsey]

I'm glad mine didn't do that. So what do you do when you want to change the glass, or remove it for some reason, like I did to get a large piece of furniture into the house?

[gfretwell]

Yeah, you just need a rock

[Clare Snyder]

All the suppliers we dealt with at both window companies I worked for used internal beading exclusively. Lots of good reasons - particularly up here where it can get very wet, and then very cold.Don't want ice building up behind the glass retainer bead, expanding and knocking it off!!! Not to mention the very obvious security issues previoslu alluded to,

[Clare Snyder]

I fail to see how that comes into the equation

I defy you to kick in an internally beaded Rehau profile window without breaking the glass. Sure, you may be able to do it on a cheap-ass window from Home Despot

If you can get in and out without breaking something to set off breakage detectors, and without physically opening a window or door to trip tamper sensors it's a whole lot safer for the theif / burglar.

[Clare Snyder]

I used to remove sealed units from Rehau windows without breaking them - and they were some of the best sealed vinyl windows on the market (There were EuroVinyl manufactured windows, manufactured using Rehau profile vi nyl extrusions - some of the best in the business in the '90s and early 2000s. We didn'thave many "leaker" units to replace, but sometimes they came with the wrong glass installed (not LowE or LowESquared - or the customer decided they wanted obscured glass in the bathroom - or the stained glass transom window wasn't available when the window went in and had to be field installed later.

Over 25 years now in my house and I have not had a single sealed unit lose it's seal

[Clare Snyder]

If I had to remove the glass to get something in/out the tilt/turn sashes can be removed in less than 2 minutes - and replaced just as fast - without tools - from the inside. Being they are virtually all on the second floor I don't anticipate it being an issue in any case.

Removing the fixed panel (or even the slider) from my patio door WOULD be significantly more difficult

[Rod Speed]

Break it if you arent changing it because its already broken or cracked.

Accept the fact that you will need a new one. Or don't buy a place that cant get a sofa thru the f****ng door. You can get a car thru my patio doors if you take both 8x4' panels out. And anything that you can ever put in the house thru the normal open patio door. At least one in each room except the bathrooms and dunnys.,

[Clare Snyder]

Not on mine -- - -

[gfretwell]

Most old style sliders just lift off the track. Wind code sliders are a little different.

[Clare Snyder]

Removing the slider is trivial compared to removing the fixed panel on mine. It's possible - but it will take a good hnalf hour and a lot of grunting and swearing - - - -
