Two ways to enclose a terrace: with a thermal break, to gain a room you can live in all year, or with a standard (non-insulated) system, to cover a utility area, a porch or a large terrace. We help you choose.

Summary
Terrace and porch enclosures in Granada and Malaga in two versions: thermal break, to gain a room you can live in all year without condensation, and standard, to cover utility areas, porches or large terraces. Fixed and retractable roofs, and glass curtains if your community does not allow profiles. Technical survey first and a free online quote.
Before talking about profiles, the key question is what you want the space for. If you want an extra room that you use all year round, you need a thermal break enclosure. If you simply want to cover an area such as a utility space, a large terrace or a porch, a standard non-insulated enclosure is usually enough.
A thermal break profile has an insulating strip separating the inside face from the outside one, so the aluminium does not carry the cold or heat through: no condensation, no 'sweating' frames, and the room behaves like the rest of the house. For that case, have a look at our glass room. A standard enclosure protects from wind, rain and dust but does not aim to match the indoor temperature.
Enclosures are our speciality. We study every terrace before proposing anything, and the manager is on site for every job, working with a team of professional fitters. If your community of owners does not allow profiles on the facade, a frameless glass curtain is the alternative.
Ask yourself whether you will live in that space. A study, a winter dining room or a playroom call for a thermal break; a utility area or a porch to store bikes do not. If in doubt, send us photos and measurements and we will advise you, with no obligation.
On penthouses and terraces we first check for possible water leaks, the load the slab will carry and the base the enclosure will sit on. As for permits, we advise you on the procedure your particular case requires.
| Thermal break enclosure (glass room) | Standard enclosure | |
|---|---|---|
| Profile | Aluminium with thermal break | Aluminium without thermal break |
| Use | An extra room, comfortable all year | Covering an area: utility space, large terrace, porch |
| Comfort | Performs like the rest of the house: no condensation | Does not aim to match the indoor temperature |
| Roof | Insulated sandwich panel (usually 50-80 mm), quiet in the rain | Depending on the case: fixed, retractable, glazed or panel |
| Examples | Baby's room on a terrace, winter dining room, study | Utility areas, drying spaces, porches |
Thermal break profiles, insulated glazing and an insulated roof. It performs like the rest of the house and is used all year.
Non-insulated aluminium profiles for utility areas, drying spaces, porches and large terraces. Protection from wind, rain and dust.
In a thermal break enclosure, the insulating strip prevents thermal shock between inside and outside: the frame does not 'sweat' in winter.
Insulated panel roof, glazed roof or retractable roof that opens to the sky in good weather.
We enclose and roof porches on detached homes so you can enjoy them in any weather.
A glass curtain encloses the terrace with tempered glass and no vertical profiles, respecting the facade.
It comes down to the profile and, above all, the use. A thermal break enclosure has aluminium profiles with an insulating strip between the inner and outer faces, so the frame does not conduct temperature and there is no condensation.
With an insulated roof and double glazing, the terrace becomes an extra room you can use all year. A standard enclosure uses non-insulated profiles: it protects from wind, rain and dust but does not aim to match the temperature of the house.
It is the logical choice for utility areas, porches or large terraces that will not be used as a room.
A complete thermal break enclosure, what we call a glass room or conservatory: insulated profiles, double glazing and an insulated panel roof that is also quiet when it rains. We carry out a technical survey first and present a proposal with drawings.
You will find all the details on our glass room page.
In many cases, yes, with a glass curtain. Tempered glass panels slide and stack to one side, with no vertical profiles, so the facade barely changes.
It has no thermal break at the bottom, but solar control glass greatly reduces heat gain. It is still wise to check with your community before installing it.
It depends on the municipality and on each case. We advise you on the procedure your case requires and provide the technical documentation for the application.
In buildings with a community of owners, their approval is also needed.
Whether it is thermal break or standard, the dimensions, the roof type (fixed, retractable, insulated panel or glass), the openings, the glazing and what the base of your terrace requires. Every case is different, so we do not publish indicative prices.
