KDG Standard double glazing will achieve around 10% Perceived Sound Reduction (PSR)
KDG strongly suggest that if your primary reason for retro-fit double glazing is noise reduction, then prior consultation with an acoustic engineer is advisable. The reason for this is KDG cannot be held responsible for sound intrusion through or around other areas of your home.
*Perceived Sound Reduction compares the glass performance as a ratio compared with 3mm float glass.
*All of KDG's double glazed units include Warm Edge Spacer Bars and Argon gas as STANDARD
KDG 6.38mm Laminate double glazing achieves 35% PSR

NZ homes are often cold and damp. With the increased insulation of double glazing, condensation is significantly reduced, resulting in drier windows with less mould and mildew.
Retro-fit double glazing can bring your home up to todays living standard and increase its resale value at the same time. Potential house buyers are looking for efficient, well insulated homes.
A double glazed house consumes less energy to heat or cool it helping the environment. Your old glass and aluminium is sent off to be recycled.
Two panes of glass are much harder to break than one. Improve the security further still by using toughened or laminated glass.
With KDG's 4 Seasons Low E you can now reduce unwanted Solar Gain whilst allowing maximum light transmission.
Double Glazing is the process of putting two panes of glass together to create an insulated glass unit (IGU). Watch the video
If noise reduction is your priority, we recommend using Silence glass in your double glazing, as this will give you 60% PSR
