   此前，国内的沥青瓦中级市场一直被国产彩砂沥青瓦把持，几乎快要被垄断的节奏，但是产品的缺点使得市场持续高涨的可能性降低，新的产品只有取代旧的产品的缺点，并一直延续产品的优势就成为沥青瓦厂家改良的方向。进口彩砂沥青瓦的出现，不但提升了产品的外观效果，更多的是把产品的档次提升到高端领域，使得产品的屋面效果能够长时间的延续。好不夸张的说，它与国产彩砂沥青瓦已经不是一个档次的产品，因为丢掉彩砂外观的美丽，是失去屋面较为耀眼的光彩，无法把保色年限延长，直接褪色之后暴露出来的内部材料也会因为不能抗冻、耐候而变成鸡肋。环环相扣的沥青瓦内部原材料之间的兼容稳定性非常的重要。这不仅是长时间市场的磨合之后得出的结论，也是大量的项目实践之后得出的真知。
