Bringing natural light indoors and saving energy are top priorities for homeowners upgrading their windows. But modern joinery offers even more benefits, including exceptional sound insulation. Here's what you need to know from our years of experience in window selection and installation.
Windows play a critical role in maintaining thermal comfort. Poorly performing or outdated units can account for up to 30% of a home's heat loss, leading to discomfort and higher energy bills.
Beyond energy efficiency, soundproofing is a key consideration for new windows. Whether it's a car horn jolting you awake or motorcycle noise disrupting your peace, single-pane glazing amplifies these disturbances.
Urban dwellers, remote workers, or even rural residents near farms benefit from acoustically superior windows. High-quality options reduce noise by 28 to 40 decibels, creating a noticeably quieter environment.
Daily disturbances like car alarms, sirens, or neighborhood chatter demand windows with proven acoustic performance across all joinery elements.
The secret lies in glazing quality and design. Asymmetric thicknesses—such as a 10mm outer pane—combined with spacers that absorb vibrations, dramatically cut external noise.
To match insulation to your noise levels, look for the Acotherm label, which rates joinery from AC1 to AC4. AC4-rated windows deliver the highest performance, attenuating noise by up to 40 decibels.
Noises exceeding 60 decibels are clear nuisances, but even milder sounds like a 50-decibel bark can grate if persistent. An AC4 window reduces that bark to just 10 decibels—like a gentle breeze through trees—transforming your daily comfort.
