Replace the glass, not the entire frame.
At Showcase Plastics, we offer a supply only service, and supply and fit replacement glass and sealed units for windows, doors, conservatories and other domestic and commercial glazing throughout Essex.
Whether you have a misted double glazed window, a blown sealed unit, cracked glass, damaged glazing or simply want to upgrade the performance of your existing windows, we can help you find the right replacement.
Why replace an entire window when the frame is still perfectly good?
A replacement sealed glass unit can often restore the appearance, insulation and performance of an existing window at a fraction of the cost and disruption associated with complete window replacement.

Double glazed windows
Triple glazed windows
uPVC windows

Have a misted, broken or damaged window? Speak to our team today for advice, measurements and a replacement glass quotation.
One of the most common reasons homeowners contact us is because their double glazing has started to look foggy, cloudy or misted.
You may have noticed:
If the condensation is between the panes of glass, rather than on the room-side surface, there is a good chance that the sealed glass unit has failed.
Despite the name, a “blown window” doesn’t necessarily mean that the entire window has failed.
A double glazed window normally consists of a sealed insulating glass unit, made from two panes of glass separated by a spacer and sealed around the perimeter.
Over time, the edge seal can deteriorate because of age, weather exposure, temperature changes, movement or general wear.
Once the seal fails, moisture can enter the cavity between the panes.
The result is the familiar misted, cloudy or fogged appearance.
This is commonly referred to as:
Blown double glazing
Misted double glazing
Failed sealed unit
Misted window glass
Cloudy double glazing
Failed double glazed unit
The important thing to understand is that the window frame itself may still be completely serviceable.
In many situations, replacing the sealed glass unit is all that’s required.
This is one of the biggest advantages of replacement glazing.
If your existing uPVC, aluminium or timber frame is structurally sound, there may be no reason to remove it simply because the glass has failed.
Replacing the glass can provide a much more targeted solution.
✔ Less disruption
✔ Less waste
✔ Faster turnaround
✔ Lower cost than replacing the entire window
✔ Retaining your existing frames
✔ Improving the appearance of your property
✔ Improving thermal performance
✔ Upgrading the specification of your glazing
It is particularly useful where you have several failed units throughout your property and don’t want the expense of replacing perfectly usable frames.
Not every window needs the same type of glass.
At Showcase Plastics, we can help you select a glazing specification based on the application, existing frame, performance requirements and your priorities.
Ideal for replacing failed or damaged double glazing in:
A modern replacement unit can restore the clarity and insulating performance of an older or failed unit without necessarily replacing the surrounding frame.
If you’re looking to improve thermal performance or upgrade an existing installation, replacement triple glazing may also be an option where the frame and glazing system are suitable.
Triple glazing uses three panes of glass and two insulating cavities, offering the potential for improved thermal insulation compared with conventional double glazing.
However, triple glazing is not automatically suitable for every existing frame, so we’ll help you establish what is practical for your particular application.
Replacement glazing isn’t simply about replacing clear glass with another piece of clear glass.
There are numerous glass specifications available depending on what you’re trying to achieve.
Low-emissivity coatings can help reduce heat transfer through the glazing and improve the thermal performance of an insulating glass unit.
This makes Low-E glass a popular choice where homeowners want to improve the efficiency of existing windows.
Toughened glass is processed to increase its resistance to mechanical and thermal stresses.
Where safety glazing is required, the correct specification is important.
This can be particularly relevant for doors, low-level glazing and other locations where impact safety needs to be considered.
Laminated glass consists of glass layers bonded around an interlayer.
It can provide additional security and safety characteristics and is also available as an option where improved acoustic performance is required.
Living next to a busy road? Close to a railway? Have noisy neighbours or commercial activity nearby?
The right acoustic glazing specification can help reduce the transmission of external noise through your windows.
It can be particularly worthwhile for properties in busy urban areas.
Large areas of glazing can allow significant solar heat gain during warmer weather.
Solar control glass can help manage solar energy entering through the glazing while still allowing natural daylight into the property.
Need privacy without sacrificing natural light?
Obscure and patterned glass can be ideal for:
There are different patterns and levels of privacy available, allowing the glazing to be functional as well as attractive.

We’re based in Maldon, Essex, and supply customers throughout the surrounding area.
Our local service means you can deal with a team that understands the needs of homeowners, tradespeople and property professionals in the area.
If your frame is still suitable, replacing the glass can be a much more targeted solution than replacing the complete window.
You retain the existing frame while addressing the actual problem — the glazing.
From standard replacement double glazing through to specialist options such as:
we can help identify an appropriate specification for your requirements.

Choose the option that works best for you.
Collect your replacement glass or arrange the appropriate supply and fitting service.
A cracked pane, misted unit or failed sealed unit can be frustrating — especially when the rest of the window is perfectly fine.
Replacing just the glazing can be a practical way to restore the appearance and functionality of your existing installation.
We supply replacement glass for:
uPVC, aluminium and timber windows, including individual panes and multiple replacement units.
Replacement glazing for patio doors, French doors and other glazed door applications, subject to the correct specification.
Replace failed or misted conservatory glazing without automatically replacing the entire conservatory structure.
Replacement sealed units for offices, shops, commercial premises and property maintenance projects.
Remove unsightly misting and cloudiness and restore clear, attractive glazing.
Modern insulating glass can provide improved thermal performance compared with older or failed units.
Better-performing glazing can reduce heat transfer through windows and contribute to overall energy efficiency.
Better glazing can help reduce cold areas around windows and make rooms feel more comfortable.
Specialist acoustic glass can help reduce unwanted external sound.
Obscure and patterned glass options can provide privacy while retaining daylight.
Where appropriate, toughened or laminated glass can provide additional safety characteristics.
Replacing only the failed glazing means you may be able to retain a perfectly serviceable window frame rather than replacing the entire installation.
There isn’t a one-size-fits-all answer.
If your frame is damaged, warped, rotten, severely deteriorated or no longer suitable for the required glazing, complete window replacement may be the better solution.
But if your existing frame is in good condition and the main problem is the glass, replacement glazing may be all that’s required.
That’s why it’s worth speaking to us before committing to an expensive full-window replacement.
✔ The frame is still in good condition
✔ The glass is misted or blown
✔ A sealed unit has failed
✔ A pane has cracked or broken
✔ You want to improve the glass specification
✔ You want better acoustic performance
✔ You need privacy glazing
✔ You want to improve thermal performance
✔ You don’t want the disruption of replacing the entire window
Yes. In many cases, the sealed glass unit can be replaced without replacing the entire window frame. This is particularly useful where the existing frame is still in good condition.
A “blown” window usually refers to a failed sealed double or triple glazed unit. The perimeter seal has deteriorated, allowing moisture into the cavity between the panes and causing misting or condensation.
Usually, the most effective long-term solution is to replace the failed sealed glass unit rather than attempting to repair the seal itself.
Not necessarily. If the frame is structurally sound and suitable for replacement glazing, the damaged glass unit may be replaced independently.

Simply contact Showcase Plastics with details of what you need. Our team can discuss the application, measurements, glass specification and whether you require supply only or supply and fitting.
If your windows are misted, cloudy, cracked, broken or no longer performing as they should, you may not need to replace the entire window.
