金属屋面瓦对房屋而言是非常重要的，特别是现在的很多别墅都喜欢用瓦来做装饰，那么别墅金属屋面瓦到底如何来选择呢？那么金属屋面瓦有又有哪三大方面的功能呢？
防雨防漏。屋面铺上瓦后应将屋顶严密复盖，把雨水与屋顶很好地隔离开来，不管雨多大或下多长时间，雨水都不会渗透到屋子里，否则将损坏房屋内的装修及设施，以致无法居住使用，还会损坏整个房屋结构，甚至结束它的寿命。所以，渗漏会给人们带来诸多麻烦和无限烦恼，防漏是第一位。
flesh? Is there a duenna in the world that escapes being ill-tempered, wrinkled, and prudish? Avaunt, then, ye duenna crew, undelightful to all mankind. Oh, but that lady did well who, they say, had at the end of her reception room a couple of figures of duennas with spectacles and lace-cushions, as if at work, and those statues served quite as well to give an air of propriety to the room as if they had been real duennas.”
So saying he leaped off the bed, intending to close the door and not allow Senora Rodriguez to enter; but as he went to shut it Senora Rodriguez returned with a wax candle lighted, and having a closer view of Don Quixote, with the coverlet round him, and his bandages and night-cap, she was alarmed afresh, and retreating a couple of paces, exclaimed, “Am I safe, sir knight? for I don’t look upon it as a sign of very great virtue that your worship should have got up out of bed.”
隔热保温。随着人们生活水平的提高，金属屋面瓦对居住条件自然提出更高要求，居住舒适性即是重要指标之一。要想舒适，房屋的隔热保温性能必须良好，金属瓦就担负着这一重任。瓦本身的厚度有限，仅有一公分多，靠此无法隔热，隔热全靠瓦下严密封闭的那层空气，封得愈死，隔热愈好，否则这层空隙没有多大作用。这正如双层玻璃保温隔热的道理一样，虽然两层玻璃间仅有一层薄薄的空气层，但只要四边封得严，隔热效果就会很好。
装饰性。建房屋同做衣服一样，除穿着之外一定希望外观别致漂亮。彩石金属瓦就是房屋的“外衣”，瓦的色彩及瓦形的设计，铺装好坏对建筑物的外观都起着决定性作用。金属屋面瓦这个“外衣”比人的外衣要重要的得多。外衣穿着不合适不漂亮，马上可以换一件，瓦则不然，即如不合适，要换瓦谈何容易，既费钱又费工时，房屋这个“外衣”一穿就是几十年。因而选瓦时要慎之又慎，不可图一时省个小钱而误了大事，后悔莫及！金属屋面瓦要想漂亮，有以下几条：色调柔和均匀，不俗不刺眼又亮丽，最好为哑光型。瓦与瓦之间没有色差。上房后，每片瓦颜色均匀一致，没有深浅之分，更无花斑。颜色耐久风刮日晒、雨淋不褪色。瓦形坡纹柔和，给人以美感。大厂的瓦形都是经专家从美术角度精心设计的，铺在屋面上会给人美观亲切之感。尺寸精确、搭接严密、铺装误差小。好的彩石金属瓦，铺好后横竖斜全呈直线，犹如印刷般整齐，漂亮极了。
I may well ask the same, senora,” said Don Quixote; “and I do ask whether I shall be safe from being assailed and forced?”
“Of whom and against whom do you demand that security, sir knight?” said the duenna.
“Of you and against you I ask it,” said Don Quixote; “for I am not marble, nor are you brass, nor is it now ten o’clock in the morning, but midnight, or a trifle past it I fancy, and we are in a room more secluded and retired than the cave could have been where the treacherous and daring AEneas enjoyed the fair soft-hearted Dido. But give me your hand, senora; I require no better protection than my own continence, and my own sense of propriety; as well as that which is inspired by that venerable head-dress;” and so saying he kissed her right hand and took it in his own, she yielding it to him with equal ceremoniousness. And here Cide Hamete inserts a parenthesis in which he says that to have seen the pair marching from the door to the bed, linked hand in hand in this way, he would have given the best of the two tunics he had.
Don Quixote finally got into bed, and Dona Rodriguez took her seat on a chair at some little distance from his couch, without taking off her spectacles or putting aside the candle. Don Quixote wrapped the bedclothes round him and covered himself up completely, leaving nothing but his face visible, and as soon as they had both regained their composure he broke silence, saying, “Now, Senora Dona Rodriguez,
