Thermal cap for single glazed window

[hic]

Economically,
(at the price of some concessions for simple glazing),

the advantage is "always" at the thermal plug.



Single glazing + Thermal plug (against the rest of the world)

Simple glazing is the most energetic passing
(in all cases, the glass will absorb energy and heat up - triple glazing or not)


A thermal plug of R = 5 is the most insulating

In cold weather, you uncork that when there is sun,
and that the thermal balance is positive (to be automated or not).

Is it a block of polystyrene which comes to be applied against the window?
What thickness?

So less than 15cm, since the window has some insulation.

(Controversial. A multi-layer in 20 layers, 5 cm)

Small question, simple glazing is just for money? Because having a double would make life much easier when the price to go from single to double varies by around 15%.

But the price to replace an existing simple with a double

It is clear, the replacement costs the eyes of the head, while a plug in itself is something else (still it is necessary to have the window edges suitable for this kind of thing, otherwise work which costs an arm)
But for new installations? ...

In the end, your "corked" window will certainly be more isolated than the rest of the walls (because there is still a majority of buildings, old, which are not at all!)?

This reminds me of a discussion we had on the vitrification ...

Otherwise also review this one about the thermal performance of windows: https://www.econologie.com/forums/le-triple- ... t4570.html

hi Christophe

That i would sum up
In any case, the windows are always the coldest spots,
13 ° for the interior glass of triple glazing when it freezes.

Not everyone wants to invest in isolation,
and double glazing can go last, as an option
or replaced with a thermal plug


Instead of installing a removable thermal plug,

we can consider a winter thermal plug (easily removable)
, which condemns
certain windows and double French windows,
north side windows, WC bathroom.

I remember the forum offered insulating shutters!

Well no! the title you changed "was" "" "THERMAL PLUG" ""

that means that the windows are "poor" in insulation, (8 °, 10 ° when freezing for double glazing)
it's expensive for not much (13% of leaks)

THAT IN ALL CASES "THE THERMAL PLUG IS PRIORITY"



Don't tell me that the double-glazed or triple-glazed budget represents 15% of the total buget!
it is expensive for this small gain !!

(especially as the UW goes from 1,3 to 3 for double glazing,
in short the economy single glazing double glazing represents only a division by 2 of the energy expenditure
what relation with an R = 5?)

We only use it when it's cold, in winter,
when it is mostly dark,
so we don't need transparency, a thermal cap is enough



Besides, if an opening is intended to bring energy into a room (well of light),
the glazing does not need to be of optical quality,
a simple plastic is enough (and without polycarbonate) !!!
which in fact is a better insulator than glass and lets in more energy,
for good for less.

Technological utopia is very expensive for dreamers! (Multi-glazing at R = 5? )
and the need for this geek fishing

While we have an alternative that explodes performance for much less. (THERMAL PLUG )

crop me ??

It remains to invent the removable thermal cap,
that we install for the winter,
(which could be between the shutter and the window,
which would be easier and more airtight than an indoor installation,
but the window sill is a thermal bridge)

for a room like a bedroom,
"cold" rooms on the North side or WC slle bath,
all that is little or not often used

as well as the front door and other French window,
cellar door, garage, attic


the best installation is always done at design,
after it is difficult to catch up

Start by thinking of everything! but before
