Windows and doors are key elements of every house as they provide energy efficiency, security, and aesthetic appearance of the building. Properly chosen materials and quality installation enable insulation from cold, noise, and moisture, reduce energy loss, and increase user comfort.
1. Windows
PVC Windows
- The most common choice due to price and low maintenance needs
- Multi-chamber profiles, double or triple glazing
- Material price: 300–700 KM/m²
- Installation price: 100–250 KM/m²
- Total: 400–950 KM/m²
- Advantages: long lifespan, good insulation, resistance to moisture
- Disadvantages: less aesthetically pleasing compared to wood
Wooden Windows
- Natural material, aesthetically appealing
- Obligatory treatment against moisture and pests
- Material price: 500–1,200 KM/m²
- Installation price: 200–400 KM/m²
- Total: 700–1,600 KM/m²
- Advantages: natural look, good insulation if done qualitatively
- Disadvantages: more expensive, requires regular maintenance
Aluminum Windows
- Resistance to moisture, UV rays, and corrosion
- Frequently used for modern facades and large glass surfaces
- Material price: 400–1,000 KM/m²
- Installation price: 150–300 KM/m²
- Total: 550–1,300 KM/m²
- Advantages: long lifespan, resistance to weather conditions
- Disadvantages: lower thermal insulation if not with thermal break
2. Doors
Interior Doors
- Material: wood, MDF, laminate
- Material price: 150–600 KM/piece
- Installation price: 50–150 KM/piece
- Total: 200–750 KM/piece
- Advantages: diverse design, easy installation
- Disadvantages: sensitive to moisture and mechanical damage with low quality
Exterior Doors
- Material: steel, wood, aluminum
- Material price: 500–2,500 KM/piece
- Installation price: 200–500 KM/piece
- Total: 700–3,000 KM/piece
- Advantages: security, good insulation, and resistance to weather conditions
- Disadvantages: more expensive option, wooden doors require maintenance
3. Typical Problems and Mistakes
- Incorrect assembly – air and water leakage
- Inadequate sealing – condensation and draft
- Inappropriate material choice for climate conditions
- Insufficient insulation of glass packets – greater energy loss
- Inconsistent design with facade or interior
4. Implementation Tips
- Always follow project documentation and installation standards
- Use quality sealants and joints for insulation
- Properly dimension and install windows for optimal lighting and ventilation
- Regularly maintain wooden and aluminum surfaces
- Choose material according to climate conditions and aesthetic preferences
