Pvc windows import request Mauritania

We are interested in purchasing PVC windows for our business. We noticed that your company is a reputable supplier in the field and we would like to know the different modes of PVC windows you offer and their prices.
We need quality PVC windows for our premises. We need windows that are durable, energy efficient and have good sound and heat insulation. We also want these windows to be sliding if not tilt-and-turn, available in different sizes to suit our working environment.
