Looking for replacement double or triple glazed units in Maldon, Essex?
If your windows are misted, cloudy or “blown”, you often do not need full new frames. Showcase Plastics supplies replacement double glazed units (and triple where suitable) — cut to size for collection, delivery, or supply and fit across Essex.
We work from Unit 6, Heybridge Industrial Estate, The Causeway, Maldon CM9 4XL, for homeowners, landlords and trade.
Condensation between the panes, a foggy look, cracks or a failed seal usually means the sealed glass unit has failed — not necessarily the whole window.
In many cases the frame is still sound. We measure (or you supply sizes), specify a new unit, and replace the glass only. That is normally quicker and cheaper than replacing the entire window.
This is often called:
blown double glazing
misted double glazing
failed sealed units
cloudy window glass
A double or triple glazed window uses a sealed unit: two or more panes, a spacer bar, and a perimeter seal that keeps the cavity dry.
Seals fail over time because of:
Moisture then enters the cavity and shows as misting between the panes. Replacing the sealed unit is the usual fix.
Replacing replacement double glazed units (or suitable triple units) is typically:
The new unit is made to fit the existing frame so the window can perform like new again.
Upgrading the glass can give you:
Better thermal performance — modern energy-efficient double or triple glazing helps keep heat in.
Clear glass again — removes the cloudy, misted look.
Less noise — acoustic glass options where external noise is a problem.
Safety and privacy options — toughened, laminated or obscure glass where needed.
Lower running costs over time — better insulation than a failed old unit.
We aim to keep quoting straightforward — estimates within 24 hours where we have the right information.
When specifying replacement double glazed units, options can include:
We will advise what fits your frame and what is worth upgrading.
We supply sealed units for a wide range of systems, including:
Trade: units cut to size for installers.
DIY / homeowner: supply only or supply and fit, depending on the job and location.
If the frame is rotten, distorted or beyond repair, we will say so — unit-only replacement is not always the right answer.
These are classic signs of blown double glazing.

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.

The lifespan of a sealed unit varies depending on the glass, spacer, seal, manufacture, installation and environmental conditions. Properly manufactured and installed units can provide many years of service, but seals can eventually deteriorate over time. As a general rule – most double glazed units last 10–20 years before the seals may eventually fail.
