Which energy-saving windows will let you earn the most and will bring a satisfied customer?

In our May ranking of energy-saving three-pane windows, you get several dozen hours of comparing, analyzing, and verifying suppliers and finished windows.

In the May comparison, the Made in Poland – Decco 83 product strengthened again in the first place of a full-fledged energy-saving window.

Decco 83 is a better and better prepared system that already includes a dedicated sliding HS system and doors in its portfolio. This is a complete product at a totally underestimated price. Lower than in the rival companies by over 8%!

Winner of the May PVC windows ranking: Decco 83

As a local patriot thinking logically, you should think about using Decco 83 wherever the customer wants a very sensible product. Yes, maybe without fireworks, but really energy-saving: with three gaskets between the frame, the sash, and three panes Ug = 0.5

Decco 83 is a complete product at an extremely low price.

We also have novelty in our list. It is previously unavailable Kommerling 76 MD. Of course, in the version with three gaskets.

At the current price, it is a very serious competitor for our leader in the quality / price comparison – Veka Softline 76 MD which is once again in a row a winner of the OPTIMAL purchase category.

In our subjective opinion, Rehau Synego 80 won the ranking of the highest quality three-pane energy-saving windows. It is true that you have to pay nearly 10% more for it than for the Veka 76 MD, but it is a full “eighty”.

Synego 80 is a system with phenomenal real wood veneers, excellent PVC quality guaranteed by the global REHAU concern. The optimal solution for a client of your company looking for a brand. In addition, it has the best Siegenia Titan AF fittings on the market. In summary, buy, install and get referrals from satisfied customers.

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 PCV 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 PCV colors is about 4 weeks depending on the color. The production time of PCV doors is also about 4 weeks. Aluminium 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 joinery 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 joinery 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 joinery 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 joinery 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.
