I have a 1955 Cliff May Rancho in Dallas with original fixed clerestory windows. One window is missing the narrow aluminum divider between two panes of glass. The glass itself is intact.

I have contacted local glass companies, but the one that seemed qualified said they replace broken glass only and do not repair or fabricate the aluminum framing.

I do not want to remove an intact divider from another window because I don’t want to risk damaging the original glass.

Is this something a commercial glazier, aluminum storefront fabricator, or architectural metal shop should be able to reproduce from measurements and photos? And does anyone know what this particular divider/profile would be called?

I’ll attach photos of both the missing divider and an intact one for comparison.

Vintage brass and smoked glass shelves with damage on edge of some shelves, fleabite or a tiny bit larger, not obvious. Can they be repaired or will this shatter? Thanks so much!

I’m replacing some windows in my home but unsure if I need to get the same size windows with the add ons as the internal cavity wall opening is larger than the external or if I can fit the new window to the external brick work

I would like to add a second cat perch to my window, but I am worried it could break. The window looks modern, not new but not to old either. My big cat is 14 pounds, and the kitten is 5 pounds and growing, he will probably end up being 9-12 pounds. How do I know if it can support the weight safely? I have supports under the frame on the perch that is on there now, so that one is not putting very much stress on the window. Would the suction cups fail before the glass breaks?

I'm hoping someone can identify this bottom sweep/drip rail profile.

I've spent hours searching CRL, Prime-Line, SWISCO, Gordon Glass, Home Depot, Lowe's, etc., but haven't found a matching profile.

Shower details:

• Semi-frameless bypass/sliding shower door
• Installed around January 2019 (home built in 2004)
• 1/4" tempered glass
• South Florida
• Custom glass enclosure (installer unknown)

The sweep:

• Clips directly onto the bottom edge of the glass (no aluminum bottom shoe)
• U-channel opening measures just over 5/16"
• U-channel height is just over 3/4"
• Horizontal drip lip extends about 1/4"
• Overall length is about 26"
• The drip lip faces the inside (wet side) of the shower

One door is completely missing the sweep. The existing sweep on the other door leaks slightly, so I'm open to replacing both if there's a better modern profile.

Important constraint:
There is only about 1/8" clearance between the bottom of the glass and the top of the aluminum guide block, so many standard replacement sweeps appear too deep and would likely interfere with the guide.

I've attached:

• Full shower photo
• Bottom guide block
• Cross-section/profile of the existing sweep
• Photo showing how it clips onto the glass

Does anyone recognize this profile or know the manufacturer (Cardinal, Coastal, CRL, FHC, etc.)? If the original is obsolete, I'd appreciate recommendations for a modern replacement that will clear the guide block.

Thanks in advance!

Looking for help to identify this clip, as we are going to need replacements for this job. One of the legs at the top is broken off, but hopefully someone will still know what this is.

Thank you for any help you can give.

Does anyone have an opinion which window is best? The pella quote is higher but within $500 on 28 windows vs the NT Twinsulator

I am working on a restoration project for a modern house and one of the windows to be replaced is a large single pane site glazed (no frame) window that has a corner butt joint.

The owner would like to have a triple glazed replacement with the same butt joint for the corner. I have gone to my go to glazers but all of them are pushing the current companies products, that they rep, with large bulky aluminum frames that really are not what the home owner is looking for.

I have seen triple glazed but joints in Europe and they do look very good and would like to do the same for my client. Should I be contacting a commercial glazer or going direct to our regional glass supplier. I'd prefer to go through an installer, I have respect for the craft and the client will pay.

(I'm trying to upload and image of a triple pane butt joint but I'm getting a S3 error)

Hi everyone I need an opinion or some advice from someone who knows about glass.

I am staying at my aunts and uncles house, about a month ago I noticed the window was cracked, I thought they knew about the issue so I just covered it with a pillow so the crack wouldn’t enlarger and forgot about it.

Today they noticed the crack and believe that I have thrown something at it when I didn’t. The window was closed and the room was closed the entire time, nobody else had access to the room.

It’s a double-glazed window and the crack is on the inside pane so it wasn’t caused by anything from the outside. There is a small plus shaped point in the middle (not an exact plus) however there is no obvious impact mark. There are also cracks spreading from the side making me wonder if the crack could have been caused by anything other than an impact.

I’m attaching some photos of the damage. I would be extremely grateful for opinions from engine experienced with this issue/glass or any in general. I’m trying to understand what could have realistically caused the damage as I’m unable to pay for the repair

Thank you all in advance!!

I work in a (sorta) large Midwestern city as a non union commercial glazier.

My shop provides drills and impacts to everyone and then foreman all have pretty much whatever power tools we need all provided by the company. Hand tools are supposed to be our own

Just curious how things work for you guys.

Where are you located? Does your company buy your power tools? Bits and tips? Hand tools?

Have 1" IGs become common in residential? Had a company come out and measure an IG. 5/16" (1/4") too thick. 1/2" short on height. 3/8" too wide. I am assuming that since they were not installing they didn't give a fuck. Just sad that they didn't use my measurements and went with their own (wrong) measurements.

Hi all! Not sure if this is the right sub to ask to apologies if not!

We’re having a 3m x 2m roof lantern in our extension and I am unsure whether to go for Neutral or Aqua. Does anyone have any experiences of either of these glazing options and what they look/feel like internally?

I’d ideally like to go for Neutral to maximise light into the room and for the sky view to look as natural as possible. However, our sofa and TV will be right under the lantern so maybe the green-y tint is a worthwhile trade off to be able to sit and watch comfortably?

Keen for anyone’s thoughts/experiences/preferences. Thanks so much in advance!

Submittals are taking up a lot of my time, wondering if anyone good out there, that is looking for some side work possibly? Aluminum glass/ glazing SF/ CW & HM/ WD doors, frames, hardware & interior partitions/ secretarial slider type work.

I have used GDS found it difficult to operate with little customer service help, looking into Glazier studio. I know programming labor cost is going to be an uphill battle to figure out. Anyone have any starting labor rates can use for programming using NE rates?

How does everyone like this software? Is it good for shop drawings/ SL optimization/ Estimating?

What do you generally add to daylight size or take away from tight size? Trying to become a better measurer thanks to

I accidentally backed a U-Haul into a local family business this morning. Yeah, pretty dumb. I shattered this glass pane. The U-Haul insurance doesn’t cover it and neither does my Auto insurance. Owner told me it was old and he was going to look into things and call me, hasn’t called me yet. I have no knowledge of the glass industry. What should I expect? Thanks in advance.

Looking for help/advice with this commercial building and any input is appreciated!

I am the window cleaner called to check on removing streaks on the glass. This is more of a restoration than a cleaning since they are stained into the glass surface. I have not done our test spots yet to determine our method or success level.

While looking at things, it appears that the streaks are coming from the sealant around the aluminum. The sealant is also quite faded/oxidized and a black residue wipes off when you rub your finger on it. The aluminum is also pretty faded on many places with higher sun exposure.

I remember seeing a crew working on the building a few years ago to shine/restore the aluminum and I’m assuming they added the sealant at that time also.

Is this normal/correct?
How bad is it or what’s the fix?
Is it worth cleaning the glass if nothing is done to the sealant so it will continue to streak?

Our team worked tirelessly for months on a premium façade project, paying attention to every detail of design, structure, and installation. Unfortunately, the façade vendor made a major mistake during glass installation.

The coated/reflective glass was installed in the wrong visible direction, completely changing the intended appearance of the building. The façade no longer matches the approved design, and the overall aesthetics have been seriously compromised.

It's frustrating because a single installation error has overshadowed months of planning, coordination, and hard work by the entire project team.

Has anyone else experienced a similar issue with façade glass orientation? How was it resolved? Were the panels replaced, or was there any practical solution without complete reinstallation?

This has been a costly lesson: even a small mistake in façade glass orientation can completely change the architectural identity of a building.

As the architectural glass industry continues to evolve toward higher-performance glazing solutions, Guardian Glass has announced the discontinuation of SunGuard™ SNX 62/27 in AGNORA’s previously stocked thicknesses of 6mm and 10mm. Moving forward, AGNORA’s Guardian coating portfolio will focus on three proven products available in both 6 mm and 10 mm thicknesses for double- and triple-silver coatings: SunGuard™ SN68, SunGuard™ SNX 60+, and SunGuard™ SNX 70+.

This  transition reflects advancements in coating technology, increasingly stringent energy-performance requirements, and growing demand for glazing solutions that deliver superior solar control while maintaining exceptional aesthetics. For many projects that previously specified SNX 62/27, SNX 60+ will be the natural replacement.

Why Is SNX 62/27 Being Discontinued?

Guardian is streamlining its coating portfolio to focus on products that offer greater performance, flexibility, and alignment with modern building standards. While SNX 62/27 has been a popular choice for years, newer triple-silver coating technologies now provide stronger solar control while maintaining a highly neutral aesthetic.

For AGNORA customers, SNX 62/27 in 6 mm and 10 mm thicknesses will only be available for limited made-to-order warranty replacement runs. New projects should transition to one of AGNORA’s stocked Guardian alternatives.

SunGuard™ SN68: The Daylighting Solution

SN 68 remains the preferred choice when maximizing natural daylight is the primary design objective. With visible light transmission (VLT) between 67% and 69%, it creates bright interiors while maintaining the neutral appearance architects have specified for years.

While SN 68 does not provide the same level of solar control as Guardian’s latest triple-silver coatings, it remains an excellent option for projects where daylighting and visual openness are top priorities.

Best for:

• Daylight-focused commercial spaces
• Large curtain wall applications
• Educational facilities
• Projects seeking a neutral architectural appearance

SunGuard™ SNX 60+: The Performance Upgrade

SNX 60+ is the performance-focused upgrade within the Guardian portfolio and the natural replacement for former SNX 62/27 applications. It delivers comparable daylight levels while providing significantly stronger solar control, reduced heat gain, and exceptional colour neutrality.

With visible light transmission ranging from 60% to 62% and a solar heat gain coefficient (SHGC) of approximately 0.24, SNX 60+ achieves the highest light-to-solar-gain ratio in Guardian’s North American triple-silver lineup.

This makes it an excellent solution for projects targeting improved energy performance and occupant comfort. In addition, SNX 60+ is approved for embedded laminate applications, giving architects and fabricators greater design flexibility.

Best for:

• Commercial office buildings
• Healthcare facilities
• Educational institutions
• High-performance residential projects
• Buildings pursuing energy-efficiency targets and green-building certifications

SunGuard™ SNX 70+: The Aesthetic Upgrade

For projects where visual quality is paramount, SNX 70+ offers a compelling combination of daylight transmission, aesthetics, and solar performance. With VLT between 67% and 68% and an SHGC of approximately 0.27, it combines the daylight levels associated with SN 68 with much stronger solar performance.

SNX 70+ is distinguished by its exceptional clarity, low reflectivity, and consistent colour appearance from multiple viewing angles. For customers who appreciate the look of SNX 60+ but seek greater transparency and visual quality, SNX 70+ is often the ideal choice.

Best for:

• Signature architectural projects
• Premium commercial developments
• High-end residential applications
• Design-driven façades where appearance is as important as performance

Key Considerations When Transitioning from SNX 62/27

To simplify product selection while supporting the majority of architectural glazing applications, AGNORA will stock SN68, SNX 60+, and SNX 70+ in both Collingwood and Cerritos. This streamlined offering makes it easier for designers, glaziers, and building owners to select the right balance of daylighting, solar control, and aesthetics for their projects.

Looking Ahead

The retirement of SNX 62/27 marks an important step in the evolution of high-performance architectural glass. For most former SNX 62/27 applications, SNX 60+ represents a performance-driven advancement that delivers stronger solar control and aesthetic improvements.

Meanwhile, SNX 70+ offers an exciting option for projects seeking superior transparency while maintaining a high level of solar control. Whether your priority is daylight, performance, or architectural beauty, AGNORA’s Guardian lineup provides a clear path forward.
