sash window double glazing

[jochem]

I want to reduce road noise and put double glazing in my sash windows. As they are stilll very good I would 'just' like to replace the single glass panel with a double glass one. Anyone got some hints/tips and where to get double glasing panels in suffolk?
thanks

We do not allow free advertising on the website I'm afraid Jochem and can only give you the names of Double Glazing Companies that pay to advertise with us. Put double glazing into the search box on the website and see who we have on board.

I suggest you contact a self-employed joiner, who will very likely be able to source the DG units via trade outlets;-- I am aware of a firm who specialises in producing a full range of DG units, for sale to the trade via their own network of depots.
