– There are 3 big companies who can manufacture the best doors. Unfortunately the other manufacture copies. ıf you demand your requirements from that 3 companies, you will see that the prices are almost same. So , what are the reasons of these differences?
– Because the cheaper doors are manufactured with downer polyurethane than 42 density.after a short time , this lack of polyurethane causes 20% energy dissipations and down falling on doors. on the other hand the quality of metal sheet effects the prices.We use qualified switches and hinges so our products are usefull and aesthetics.We use double competents insulation glaves. If you find a cheaper product at same quality of Inova’s doors , we will back pay.. And this claim shows that how we trust on our products.
