Well-thought-out customization
Custom-made PVC windows combine excellent thermal insulation with a strong price-quality ratio, long lifespan and little maintenance. Shape, size, color and finish are tailored to each type of home.

Clear answers
Your project may have different technical requirements. During the measurement you will receive advice for your specific situation.
High-quality profiles are designed for long-lasting color stability. Maintenance and orientation also play a role.
For many dimensions, yes. For very large spans, aluminum can be technically more interesting.
Multi-chamber profiles, suitable glazing and correct airtight installation can achieve very good insulation values and limit heat loss.
Clean profiles with water and a mild agent, keep drainage free and have fittings and seals checked periodically. Avoid abrasive or aggressive products.
High-quality PVC windows often last 35 to 45 years. Orientation, use, installation and maintenance determine the actual lifespan.
