TOP Window Manufacturers in Ukraine 2025: Complete Rating and Expert Advice

How to Choose Perfect Windows for Your Home and Not Make a Mistake with the Manufacturer

Choosing new windows is much more than just buying “glass in a frame.” It’s a fundamental investment in the comfort, security, and energy efficiency of your home for decades to come. A modern window construction is a complex engineering system, the quality of which determines not only the indoor temperature, but also the level of street noise, protection against break-ins, and the overall aesthetics of your interior and exterior. However, the Ukrainian market is overflowing with offers, which often leads to consumer confusion.

The key dilemma that needs to be understood before starting your search lies in distinguishing between the concepts of “profile manufacturer” and “window manufacturer.” World-renowned brands such as Rehau, Veka, Salamander, or Aluplast are actually developers and manufacturers of PVC profiles—high-tech raw materials from which frames and sashes are made. They do not produce ready-made windows. Window manufacturers are Ukrainian factories and companies, such as Steko, Viknar’off, “Ekipazh,” or “Gazda,” which purchase profiles, reinforce them with metal, install glass packages and hardware, and ultimately assemble the finished construction. The quality of the final product depends not so much on the famous name on the profile, but rather on the production culture, equipment precision, and qualifications of the installers of the specific manufacturing plant. Often a consumer may complain about “bad Rehau windows,” when in reality the problem lies in poor assembly or installation performed by a local manufacturer using that profile. Understanding this nuance allows you to ask the right questions: not “What windows do you install?” but “Who and how manufactures windows from your chosen profile?”

This rating was created to provide comprehensive and objective information about Ukraine’s leading window construction manufacturers. The company evaluations are based on comprehensive criteria that allow for a complete picture of their market position:

4. Warranty obligations: Duration and terms of warranty on window construction and installation work.
5. Market reputation: Analysis of customer reviews, presence of portfolio of completed projects, and transparency in communication.

Metal-Plastic Window (PVC) Market Leaders: Giants of the Ukrainian Industry

The metal-plastic window segment is the largest and most competitive in Ukraine. Here are companies focused on satisfying the demand of millions of households. The leaders of this market are divided into two main business models: companies that bet on production “scale,” wide distribution, and competitive pricing, and companies that focus on “expertise” in working with one premium profile brand, offering deeper knowledge, higher service quality, and extended warranties.

Table Analysis with Conclusions

Analysis of the comparative table allows us to draw several important conclusions for consumers.

Your Final Checklist: How to Properly Order Windows and Control Quality

Choosing the right manufacturer is only half the battle. To avoid disappointments and get a quality product that will serve for years, it’s necessary to approach each stage of ordering responsibly. This checklist will help you control the process.

Stage 1: Preparation and Selection

• Define your needs: Before calling a measurer, answer the question: what’s most important to you? Maximum heat retention (need 5-6 chamber profile and double-chamber energy-saving glass package), noise insulation (different glass thickness and spacer frames in glass package), security (anti-burglary hardware, triplex), or sun protection (multifunctional or tinted glass)?
• Professional measurement: Never order windows based on your own measurements. Only a professional measurer from the manufacturer can account for all window opening nuances (irregularities, wall material, expansion needs). The company must bear responsibility for measurement accuracy.

Stage 2: Contract

1. Detailed specification: Carefully read the contract and attachments. It must clearly specify the complete configuration of each window: exact profile system name (e.g., Rehau SYNEGO), number of chambers, mounting depth, hardware brand and model, glass package formula (e.g., 4i-16Ar-4-16Ar-4i, where ‘i’ is energy-saving glass, ‘Ar’ is argon filling), lamination color, windowsills, drip caps, mosquito nets.
2. Terms and Cost: The contract must fix the final “turnkey” cost (including delivery, old window dismantling, new installation, and debris removal), as well as clear manufacturing deadlines and installation dates.
3. Warranty Obligations: Ensure that warranty is provided separately for window construction (profile, glass package, hardware) and for installation work. These are two different types of warranty.

Stage 3: Installation and Acceptance

1. Control During Installation: Although you’re not an expert, everyone can control key points. The window frame must be set strictly by builder’s level (vertically and horizontally). Wall fastening must be reliable (anchor plates or turbo screws). The mounting seam must be quality foam-filled, without gaps.
2. Work Acceptance: After installation completion, check all sash operation in all modes (opening, tilting, micro-ventilation). The handle should move smoothly, without excessive effort. Check glass and profile integrity for absence of scratches. Sign the work acceptance-handover act only after ensuring everything works properly and you’re satisfied.

Hardware Selection Tips

1. Anti-burglary: For first and last floors, as well as private houses, anti-burglary hardware installation is recommended. It has mushroom cams and corresponding strikes that complicate sash prying. Pay attention to RC1 and RC2 anti-burglary classes.
2. Child Safety: If there are small children in the house, definitely order “child locks.” This can be either a handle with a key that blocks window opening, or a special blocker at the bottom of the sash that allows tilting for ventilation but doesn’t allow full opening.
3. Ventilation Modes: In addition to standard tilt mode, modern hardware allows implementation of micro-ventilation (slot ventilation) function, ensuring constant fresh air supply without drafts.

Conclusions: Investment in Your Home’s Comfort and Warmth

The conducted analysis demonstrates that the window construction market in Ukraine is mature, competitive, and diversified. Consumers have access to a wide range of solutions capable of satisfying any technical requirements and financial capabilities—from affordable standard windows for apartment buildings to exclusive aluminum systems for ambitious architectural projects.

Market segmentation is clearly visible: there are large national manufacturers such as Steko, Viknar’off, and “Ekipazh,” competing through scale, cost optimization, and wide dealer networks. Alongside them, highly specialized companies successfully operate, offering unique expertise in certain niches: “Gazda” and Darwin in Rehau systems, “Ukraine C Group” and “ANKO” in premium aluminum, “Panorama” in wooden euro-windows.

The final manufacturer choice always remains with the consumer and should be based on their individual priorities. For standard apartment glazing, an optimal solution may be from one of the PVC market leaders. For building a modern cottage with panoramic windows and sliding doors, it’s worth contacting aluminum construction experts. And for connoisseurs of ecological style and natural aesthetics, the best choice will be wooden window masters.

It’s important to remember that the quality of the final product you receive is the synergy of four key components: quality profile, reliable hardware, professional factory assembly, and, no less important, qualified installation. Investment in quality windows is a long-term contribution to your home’s comfort, quiet, security, and energy efficiency.
