# Insulated glass curtains in Alicante.

> Glass curtains with double glazing and an air gap, for using your terrace in winter in Alicante and on the Costa Blanca: insulation, noise and quotes.

## What is an insulated glass curtain?

An insulated glass curtain opens like a standard one, but each panel has two panes with an air gap between them. The gap slows down cold, heat and noise, so the terrace works as a room in winter too, or beside a busy street. We install them in Alicante and from Valencia to Murcia after a site visit and measuring.

## Which spaces are insulated glass curtains for?

They make sense when the enclosed space will be lived in all year, not only in season: an extra living room, a winter dining area or a restaurant terrace that stays open in January.

- Terraces used as a living or dining room all year
- Windy penthouses
- Homes on busy streets or near nightlife
- Restaurant and café terraces in winter
- Porches you want to bring into the house

## How is an insulated curtain different from a single glass one?

They open the same way. What changes is what gets through the glass when the terrace is closed.

| Feature | Insulated glass curtain | Single glass curtain |
| --- | --- | --- |
| Glass | Two panes with an air gap | One tempered pane |
| Cold and heat | Reduces heat transfer | Stops wind, does not insulate |
| Noise | Cuts outside noise noticeably | Cuts little |
| In winter | A living space with heating | Shelter from wind and rain |
| Best for | Year round use, noisy streets | Spring to autumn use |

## What is the process?

The same four steps for every system, from the first call to installation.

1. **Tell us about your space.** By phone, WhatsApp or the form: what you want to enclose, where it is and how you plan to use it.
2. **Site visit and measuring.** A technician sees the site, takes measurements and checks the floor, ceiling and orientation. Timing: (to be confirmed).
3. **Fixed quote.** You receive the system, materials and delivery time in writing. Timing: (to be confirmed).
4. **Made to measure and installed.** The system is made to fit your opening and we install it at your home or business. Timing: (to be confirmed).

## What can you combine with insulated curtains?

For insulation to work, the roof counts too: a fixed or retractable roof closes the space from above.

- [Glass curtains](https://luneks.es/en/glass-curtains/): Glass panels with no vertical frames that stack to one side.
- [Frameless sliding glass](https://luneks.es/en/frameless-sliding-glass/): Glass panels that slide behind one another, for wide openings.
- [Retractable roofs](https://luneks.es/en/retractable-roofs/): A roof that opens and closes with the weather.
- [Fixed roofs](https://luneks.es/en/fixed-roofs/): A permanent roof in glass, polycarbonate or sandwich panel.
- [Bioclimatic pergola](https://luneks.es/en/bioclimatic-pergola/): Adjustable louvres that control sun, shade and airflow.
- [Tensioned fabric pergola](https://luneks.es/en/tensioned-fabric-pergola/): Shade from fabric on an aluminium frame, with no building work.

## Questions about insulated glass curtains

### How much do insulated glass curtains cost?

It depends on the size, the double glazing build-up, the number of panels and the aluminium finish. We do not publish prices: the quote is prepared after we see and measure the terrace.

### Is double glazing worth it over single glass?

It is worth it if you will use the terrace in winter or live on a noisy street. If you only use it from spring to autumn, a single glass curtain is usually enough.

### Do insulated glass curtains block noise?

Double glazing with an air gap reduces outside noise far more than a single pane. (to be confirmed)

### What problems can glass curtains have?

The usual ones are badly levelled tracks, which make the panels stiff to move, and seals that wear over the years. That is why we measure the site before quoting. (to be confirmed)

### Do insulated glass curtains fog up?

The air gap reduces condensation on the inner face compared with single glass, especially with heating on inside. Airing the terrace now and then still helps.

### Can single glass curtains be swapped for insulated ones?
