The veranda A little retro, cold in winter and too hot in summer, it's over. Today's verandah must promote a pleasant temperature all year round. How? Especially thanks to glazing: windows and windows that are studied so that heat remains optimal throughout the year. The veranda must be comfortable since it is a new part of the house with a lot of advantages.
The glass walls now have a place of choice in the thermal balance. Why so much interest? A study conducted by the company Cardonnel Ingénierie has shown that the larger a window, the more insulating it is per square meter, the more solar gains are made, and the greater the contribution of light. Because of its large glazed area, the veranda becomes a model of bioclimatic construction when its materials meet standards and its implementation has been carefully chosen. Of course, all these models deal with the problem of thermal bridges. And today most materials manufacturers and manufacturers are ready to provide products that meet the new requirements: low-consumption verandas, VBCs in a way.

In parallel with technical progress, the concept of conservatory has changed to include a range of solutions that address various issues of needs, uses and budgets. But, says Jean-Luc Marchand, general delegate and spokesperson for the Aluminum Architecture Association, "whatever the solution sought, a well-designed conservatory is first and foremost a project for which the state and nature of the project will be taken into account. aspect of the future or existing housing, and the needs of the sponsors in terms of the use of the place and the financial means.) To question upstream on what one wishes to make of the veranda throughout the year will allow to to move towards the best solution. " Room to live more in contact with nature, connecting space between two buildings ... it's up to you.

One more room to live in / out
If the goal is to add a room to the house and save space without excessive work or cost, the conservatory is a good option. But in the nine as well, these constructions are making their way. And many brands, such as Renoval, offer specific offers. These models are often equipped with a flat roof (very low slope) sandwich panels, that is to say composed of several layers, including an insulator (conventional glass wool or insulation from the outside). From the outside, the roof is invisible; from the inside, the ceiling consists of panels that can incorporate lighting. To compensate for the lack of zenith light, manufacturers have planned skylights. For the walls, a powerful glazing, even with solar control, and a frame structure wood. The destination of these verandas is multiple: living room, dining room, bedroom ... In the latter case, the walls are not all glazed to maintain a minimum of privacy. "These verandas are positioned as competing extensions wood frame, ensures Pierre Tisseau, Rénoval.They are efficient from a thermal and acoustic point of view thanks to glazing and roofing, quickly assemble on site thanks to their elements prefabricated, and allow a clean yard.

The connecting veranda to punctuate volumes or bring together spaces
In renovation, a veranda can link two building bodies. In new construction, it serves as an architectural link between two volumes. It can also be embedded between three walls to fill the space and close the access. This solution has many advantages. Through its glass structure, a connecting veranda helps to modernize the building. Another plus, the offer is flexible: you can choose a glass conservatory on all sides or mix solid walls (or half-height) and glazing. "These works are made to measure but are not very expensive, and in any case less than a traditional enlargement, says Nikolas Séfériadis, Veranda Rideau.For example, the cost of a connecting veranda measuring 1 m of wide over 5 m long is less than 10,000 euros. " Finally, this type of veranda can have several destinations: entrance hall, living room ...
Southern orientation is most often recommended. The veranda will then catch all the sun's rays, an ideal situation if you live in the North. In the South too, but it will be necessary to provide a battery of solar protection (blinds or indoor velums, shutters, awnings-awnings outside, solar shading), all associated with effective ventilation ... A roof full (and isolated) is still the best barrier against the heat of zenith rays. If you choose to install your porch to the north, it will not receive direct sun but, in return, will benefit from invariant natural lighting during the day - which can be significant if you plan to build a workshop. artist. Oriented to the east, it will enjoy the sun in the morning and will be in the shade in the afternoon, which can be interesting if you live in a hot area. Oriented to the west, the veranda will be very exposed to the sun in the afternoon and the heat gain will be maximum at the end of the day.
They can go from 10 m2 to more than 100 m2. But beware: the surface does not depend only on you and you may be subject to a limitation by the land use plan (POS) and the local urban plan (PLU). Better to get information in town hall before you start. A preliminary declaration of works is enough if the surface of your veranda does not exceed 40 m2. In this case, the mayor of your municipality has one month to verify that the project complies with the rules of urban planning and construction. This period is extended to two months if you live in a classified site or a saved sector. Beyond 40 m2, a building permit is mandatory. In all cases, a building permit filed by an architect is imperative if your living space is greater, after work, to 170 m².
