- Higher quality – better window materials and specifications
- More design flexibility – custom sizes, colors, and high-end materials

“The Aluprof MB-79N is the perfect fit for mid-range spec homes. That’s a proven product chosen by many of our U.S. partners. It delivers the sleek aluminum look at a reasonable price, and it has already worked just as well for a renovated townhouse in Manhattan as for an urban infill project in New Jersey,”
says Bartek Michalak, co-owner of debesto.com
MB-79N available in standard and NFRC-certified versions
Please note that this profile is available in two versions: with or without NFRC certification.

Delivery time, payment, installation, warranty
1. What is the delivery time on debesto.com?The time of order processing is highly dependent on its specification.
For example, white uPVC windows, standard colors (anthracite on one side) can be ready for pick up or a shipment from 7 working days. The waiting time for nonstandard uPVC colors is about 4 weeks depending on the color. The production time of uPVC doors is also about 4 weeks. Aluminum doors and windows - from 3 weeks, wooden windows from 6 weeks. Furthermore, the blinds about 2 weeks, garage doors - about 3 weeks, metallic doors from 4 weeks. You’ll find estimated production time next to every product on its subpage.2. How does the payment look like? Do I have to pay the whole amount immediately?
We suggest two forms of payment: 1. 50% of advance for production of the product and 50% shall be paid before picking up/ sending the goods. 2. 100% payment in advance. This form is much more favorable because we give you an additional 5% discount depending on the group of products.3. Will I buy the windows and doors with an installation on debesto.com?
No, on debesto.com we sell only windows, doors, blinds, and gates, which we deliver to every place in the world. The installation of the windows depends on the client. We do not offer installation service because our offer is not directed to the building companies, installers, developers, and realtors that can install the windows and doors by themselves.4. If the windows would be installed by a different company, do the products keep the warranty?
Yes, the only condition is installing the product in accordance with the art of assembly and applicable standards in the country of the installation in terms of the warranty.5. Do the products that I buy have a foreign warranty?
Yes, the only condition is installing the product in accordance with the art of assembly and applicable standards in the country of the installation in terms of the warranty.Transport and delivery
1. Do you have a transport in your offer?
Yes, collaborating with debesto.com you get a complex service of windows and doors order including transport. Transport is priced individually for every project. The distance and package dimensions or its elements have an impact on the price. The presence of e.g. a huge HS window may raise the price compared to the delivery of standard windows. We always look for the best transport option, which besides the competitive price guarantees safety and punctuality of the delivery. The more you order the more you save - we send goods from different places in one transport. The location ensures favorable delivery prices to many different places. If the transport offer won’t be satisfying enough you can send your own shipping or pick up the package in person.2. what is an estimated time of the transport?
The transport time depends on the month in which the package is to arrive. To most of the countries, it is something about 3 days after packing the goods. The delivery time depends on that if the transport is dedicated (The driver is going to only one client) or in the partial load (delivery to a few clients). To countries aside from UE the time is much longer. To USA it is about 30-35 days, the delivery to Africa is very similar.3. If I order the windows and doors from debesto.com will I get transport for free?
It is possible - the final offer is determined with the client’s keeper. It depends on the size of the order and the place of delivery. At the same time, we always look for the best transport offer, which after summarizing with the prices of products allows the customer to save money on the import from Poland.4. Will I definitely get the goods on time?
Don’t worry, we know how important punctuality is in our business. That is why we deliver the goods only by using certified transport companies and we order production to the verified factories. We also track the order fulfillment all the time, to react in case of delay. We always assume a margin of error and we do not promise the client unfeasible deadline. We prefer to say honestly, that the delivery will take longer than giving empty promises.5. Are my goods insured during transport?
Yes, the package is fully insured. We deliver the goods only by using certified transport companies which have OC insurance for transported goods. If the commodity got damaged we deal with fixing the damage, so the new product can come to you as fast as possible. After that, we clarify this situation with the transport company.6. Is it possible to get a forklift unloading at the price of the transport?
Yes, it is possible but remember that we always explore the client’s possibilities in terms of unloading goods individually. Our experienced logistic section takes care of the transport organisation. It is also looking for the best solution for you in terms of value for money for transport to offered options such as the elevator or a forklift. In some countries, it happens that for example, it is much more profitable to rent a forklift at the location, than paying extra for it at the transport company.files to download
