Soundproof Patio & Balcony Doors
Designed to stop noise intrusion, our soundproof patio and balcony doors will also keep your home safe and secure. Available in timber, the specialist doors boast reductions of up to 53dB.
WHY THEY'RE SO GOOD
Noise will always travel the easiest path to your ear. Most of the time it will enter your home by squeezing through an air gap either in the building, or around the doors or windows. Otherwise, it will find the most susceptible material to pass through.
We prevent noise entering your home by ensuring there are no air gaps around the door, and by installing doors that have been acoustically treated to stop sound.
Acoustic Glazing
Our soundproof doors contain acoustic glazing, which has been coated in a noise-absorbing layer of PVB.
Acoustic Sealants
Used both during manufacturing and installation, acoustic sealant plugs any air gaps.
Multipoint Locking
A multipoint locking mechanism creates an air-tight seal around the door, preventing noise flanking.
