An extra internal pane for warmth and quiet where the original window has to stay put.
Secondary glazing is priced on the size of the opening, how the internal unit has to open and what the reveal will take. A fixed pane in a small opening is the cheapest arrangement. A horizontal slider across a wide sash window costs more, because it has to run properly and still give you access to the original window behind it for cleaning and ventilation.
We survey free of charge, measure the reveal and check what fixing is possible, then price it in writing including the unit, delivery and fitting. If your property is listed or in a conservation area, secondary glazing is often the option that is actually permitted, so it is worth having the conversation before you rule anything out.
Larger openings need heavier sections and more glass, so size is the first thing that moves the price.
Fixed panels are cheapest. Sliders and hinged units cost more but keep the original window usable behind them.
A square, sound reveal takes a straightforward fixing. Uneven or shallow reveals need packing and more careful setting out.
Standard glass for warmth, or thicker glass with a wider cavity where noise is the main problem you are trying to solve.
Secondary glazing is fitted inside, so it is a clean job with no work to the outside of the building. Here is how it runs.
We measure the reveal, check the original window and how you use it, and work out whether a fixed, hinged or sliding arrangement suits the room best.
A written figure per opening covering the unit, delivery and fitting. No call out fee for the survey and no delivery charge added later.
Units are made to your surveyed sizes so they sit tight in the reveal. We confirm the lead time in writing and delivery to us is free.
Fixed to the reveal, packed and sealed, then the operation checked so you can still get at the original window. It is an internal job, so there is no scaffolding and no mess outside.
It is one of the better fixes for traffic or aircraft noise, and often better than replacement double glazing, because the wide gap between the original window and the internal pane is what stops the sound rather than the glass thickness alone.
Yes. It adds a still air gap in front of a single glazed window and cuts the draughts around an old frame, which is usually where most of the heat is going.
That is exactly what the arrangement is designed for. Sliding and hinged units let you get to the window behind for ventilation and cleaning, and we set it up at the survey around how you actually use the room.
It is often the option permitted where replacement windows are not, because nothing changes outside and the original window stays in place. Check with your local authority, and tell us what they say so we work to it.
Secondary glazing carries cover which we confirm in writing at the survey. Our 10 year guarantee on the entire window applies to complete windows we supply and fit, so we set out the position for your job clearly rather than leaving it to be assumed.
