Top 10 Mistakes When Buying Windows: Updated with Winkhaus

Buying new windows is a major investment that affects the comfort, efficiency, and value of your home. Unfortunately, many homeowners make avoidable mistakes because they don’t fully understand window technology, materials, or installation requirements. Poor choices can lead to drafts, condensation, noise issues, energy loss, and expensive repairs.

1. Choosing Windows Based Only on Price

Cheap windows often use weak frames, low-quality glazing, and poor sealing. They fail quickly and cost more long term.

2. Ignoring Climate and Energy Efficiency

Canadian climates require triple glazing, Low-E coatings, argon/krypton gas, warm-edge spacers, and thermally broken aluminum/PVC frames.

3. Not Understanding Frame Material Differences

PVC is limited in size, aluminum is strongest for large openings, wood requires maintenance, and wood-aluminum hybrids offer premium performance.

4. Choosing the Wrong Opening Style

North American sliding windows offer poor sealing. European tilt-and-turn windows provide better ventilation, sealing, and cleaning access.

5. Poor Installation

Incorrect installation causes leaks, drafts, and structural problems. Proper waterproofing, leveling, flashing, and vapor control are essential.

6. Improper Planning for Large Openings

Large panoramic windows require engineering, strong frames, correct glazing thickness, and sometimes lifting equipment.

7. Overlooking Soundproofing

Laminated glass, triple glazing, and compression seals dramatically reduce noise—important for urban areas.

8. Ignoring Hardware Quality (Winkhaus, Roto, Siegenia)

Hardware controls locking, sealing, and window durability. Choose premium European brands like Winkhaus, Roto, or Siegenia for strong multi-point mechanisms and long-term performance.

9. Not Considering Aesthetics

Slim frames, flush installation, concealed hinges, and coordinated RAL colours create modern architectural design.

10. Forgetting About Long-Term Durability

Cheap windows degrade quickly. Warm aluminum systems and high-quality hardware like Winkhaus ensure decades of stability and performance.

Conclusion

Avoiding these 10 mistakes ensures your home stays comfortable, energy-efficient, secure, and visually appealing. High-quality European systems—especially tilt-and-turn and warm aluminum—provide the best long-term value.
