Secondary Glazing and Double Glazing are sometimes confused, but they are in fact different things. 

Secondary glazing retains your existing window and involves installing an additional pane of glass behind the existing window. In contrast, double glazing is one single window which comprises two panes of glass separated by argon or krypton gas which forms an insulating barrier. 

Here at Prior Products , we supply both options as they can both be good options for improving the energy efficiency of your home and therefore reducing your heating costs. 

Double glazing can be more energy efficient, however it can be more expensive to install and if you own a listed building double glazing may not be approved. 

If sound-proofing your property is your concern then secondary glazing may be the best option because a larger gap in between panes of glass creates better acoustic insulation. 

Our aluminium secondary glazing is manufactured to the highest standard, it is lightweight, highly effective with a range of specialist glass options for maximum thermal performance and noise reduction. It is virtually maintenance-free and you retain the exterior character of your existing windows

This product is very cost-effective with astounding simplicity and is an ideal solution for those listed properties, period properties and houses in conservation areas where window replacement is either impractical or not allowed due to planning constraints.
