Having a veranda: pure happiness. Or almost. Because if you do not take a few size measurements beforehand, it can become unlivable in summer and winter and quickly deteriorate. Result: we have reviewed the list of traps to avoid in order to fully enjoy them all year round and be able to take full advantage of them in the long term!
Neglecting the choice of glazing on the veranda
In a glazed floor-to-ceiling living space, if there is one mistake to avoid, it is to neglect the choice of glazing, the main element of the veranda. As such, it should be noted that double glazing is strongly recommended here since it promotes better thermal and sound insulation. You only have to imagine the impact of the noise caused by the rain to design it! But who says glazed space also says high brightness and potential glare. A parameter that must be taken into account, especially if you want to make the veranda a living room. So, to avoid wearing sunglasses in the middle of your veranda, the recommended solution is roof glazing including light penetration of less than 70%. As for the possible overheating of this space, also caused by its total exposure to the sun, the idea is to opt for glazing comprising a good solar index: not more than 40% for vertical panes, and not more than 35 % for those of the roof. When the warm weather arrives, you can only congratulate yourself!
Neglecting the veranda insulation
Moisture, a factor in mold and condensation on the windows, is one of the major problems of verandas. And for good reason, not only are they generally less heated than the rest of the house, but in addition, their walls, fully glazed, insulate it less well than the walls of any other living room. Add to that insufficient insulation, and there it is the drama! In conclusion: there is no question of neglecting the "isolation" step. On the contrary! Glazing, walls, floors, foundations, facades already existing (areas of extension between the house and the veranda): no space is to be omitted, because the more the insulation is complete, the more it will be effective against humidity problems. And this is not the only positive effect. Indeed, good insulation also makes it possible to moderate the differences in degrees of the veranda, known to become almost unbearable in summer (too high heat) as in winter (too low temperatures). Quickly, we isolate, and better still, we call on professionals!
Neglecting the ventilation of the veranda
Another important parameter for lowering humidity is ventilation. No question of neglecting the ventilation of this glazed space that is the veranda if you want to guarantee good air quality, prevent condensation on the windows, counter any stale smell and above all avoid it is degrading. In short, we regularly make it "breathe", as we would for the living room or bedroom, even if the passage is here, generally less frequent.
