For glass, we provide fully tempered glass as our standard options. With US standards and NFRC certifications, our energy-efficient integrated glazing units (IGU) feature double or triple panes glasses, warm-edge spacers, argon gas fill, Low-E coatings, and fully tempered glass, greatly improve the energy efficiency of the entire door. They can not only create a comfortable and natural indoor environment but also save electricity bills and heating bills around 300~500USD per year according to your whole building's fenestration areas. That's a real bargain compared to choosing a regular glazing set.
Doorwin's professional packing system guarantees all products are delivered safely and without any damage. We apply a four-point packing system. Firstly, adhesive plastic film is applied on interior wood frames and exterior aluminum frames to avoid scratches on the surface. Then, a paper board is applied after we apply air bubble film surrounding the whole windows/ doors to avoid any destruction or clash. Lastly, we place them into a durable non-fumigation plywood crate to avoid any possible damage during transportation.
With years of experience shipping our products worldwide, we could guarantee to ship our products to their final destinations intact and without any damage.
