Key Takeaways
- Rising energy bills signal inefficiency because outdated or poorly sealed windows and doors force HVAC systems to work harder and increase operating costs.
- Drafts and temperature fluctuations affect comfort as failing seals and insulation disrupt indoor climate control and workplace productivity.
- Visible damage indicates structural decline since warping, cracks, and difficulty operating windows or doors can compromise safety and property value.
- Excess noise suggests poor insulation because aging windows and doors may no longer provide adequate soundproofing for a productive work environment.
- Modern replacements enhance security and efficiency by offering improved locking systems, reinforced materials, and advanced weather-stripping technology.
