Secondary Glazing Costs & Free Quotes

Cost Guides Free Quotes Rated Tradesmen

For a long time, the preferred method for homeowners, when it came to window replacement, has been double-glazing. Lately, however, there is another method that has been rapidly gaining in popularity - secondary glazing.

Not only does secondary-glazing offer a viable and affordable alternative for soundproofing and insulating your home, but it also requires little or no maintenance over its lifetime.

This method has been so successful it has received the seal of approval by such entities as the Heritage Club and the Listed Property Owners Club.

Secondary glazing is considered the most viable option when it comes to the preservation of “listed buildings” that cannot be assigned a reclassification by the planning commission.

What is secondary glazing?


Secondary glazing involves inserting a second window behind an existing window in your home. Typically, they made from aluminium and have a very thin profile, which makes it possible to carry out its job without being obtrusive.

Secondary glazing provides an innovative way to insulate and soundproof your home against the elements and outside noise without the inconvenience and cost of replacing the building’s existing windows. They also give the homeowner the option of removing them during the hot summer months to promote better ventilation.

There are several different designs for secondary windows, given the homeowner the option to pick-and-choose the design that best fits that of their home’s decor. Below are just some of the designs available for you to choose from:

  • Vertical sliders
  • Lift-out panels
  • Horizontal sliders
  • Top-hung windows
  • Side-hung windows
  • Double side-hung windows
  • Removal door panels

Simply put, secondary glazing serves the same function as double glazing, yet costs much less. They also let you avoid the inconvenience of applying for permits because secondary glazing is not considered a permanent alteration to the property.

The cost of installing secondary glazing


Some of the things that will have a bearing on the cost of installing secondary windows include the price of the secondary window design you choose and the number of windows required for the property.

Also, if you choose a soundproofing design, that will result in an additional increase to the final cost.

Below are some standard pricing guides for secondary glazing installation:

  • Individual windows - £280 to £330
  • A five-window bungalow - £1,600 for materials and £400 for labour
  • A nine window terrace home - £300 for materials and £450 to £480 for installation
  • 10 window semi-detached properties - £3,200 to £3,400 for materials and £750 for labour.
  • A 14-window home - £4,500 for materials and £950 to £1000 for labour

Benefits of secondary glazing


Homeowners can expect to realise several benefits of installing secondary glazing inserts in their homes. They are:

Significant noise reduction in the home

Property owners who near busy thoroughfares or major sporting events and concert venues would benefit significantly from the installation of secondary-glazing windows, as they prevent noise pollution. Some designs even can also restrict the amount of light that enters your home.

One reason that secondary glazing is so effective in reducing noise is that the ensuing gap created by the installation of secondary glazing is wider than that found between regular double-pained windows, providing more of an insulating buffer.

If your home requires additional protection against noise pollution, then a further noise-reducing pane is available. They are known as heavy-duty glazed panes. They can prevent 90% of the external noise from entering your home.

Heat insulation

Studies have shown that homes with regular window panes lose 10% of the heat generated by their home heating systems, and another 15% from allowing cold draughts to enter the home.

The extra layer of glass featured in secondary glazing enables your home to retain more of its heat than regular windows. But, secondary windows are more than just a barrier; the pocket of air trapped between secondary windows and your home’s regular windows traps air that acts as an insulator against the cold.

This barrier also prevents outside draughts from entering the home, which, in turn, reduces your energy bill, which reduces your carbon footprint.

A comparison between double-glazing and secondary glazing


Double glazing

Although both techniques manage to perform the same task in the end, there are some significant differences you might want to consider before making a final decision.

The main function of double glazing is to help maintain the climate inside your home. They are made by mounting two sheets of glass on a frame to form a single unit. The resulting gap between the two panes of glass is there to provide insulation. The gap can be left as is, or filled with argon gas, which acts to slow the flow of air entering your home.

Double glazing helps keep the warm air produced by your home’s heating system from seeping out during the winter while preventing cold, outside air from seeping in.

During the summertime, the reverse is true - they prevent heat from entering and help keep the cold air in. this makes it easier for your home’s climate control system to maintain a comfortable atmosphere inside your home all year round, thus reducing your energy costs.

Secondary glazing

Secondary glazing offers an extra layer of protection behind your home’s existing windows, for even more heat retention.

Although double glazing has usually been advanced as the better option, this may not necessarily be the case. While they have been shown to provide more comfort and protection than single-frame windows, there have been cases reported where their uPVC frames have proved to be less effective than secondary glazing when it comes to reducing energy costs.

However, if you choose the high-end double glazing windows, they will generally out-perform their secondary glazing counterparts. But, the price you pay for these high-end units will be substantially more than what you would for the more popular mid-range units. So, secondary glazing would be the better bargain.

Secondary glazing also beats double glazing when it comes to noise reduction. The wider gap created by the installation of secondary glazing units provides better noise insulation than double glazing.

Another advantage secondary glazing has over double glazing is that you don’t have to make any alterations to your home to have them installed. They can be installed in the existing window space. So, you don’t have to worry about disposing of leftover material.

The labor costs for installing secondary glazing will be much lower than that of double glazing. Plus, tenants who had them installed in their flats can simply remove them and take them with them when they move.

Final thoughts


Reviews for secondary glazing has been overwhelmingly positive, and the preferred choice of owners who are more concerned about noise than insulation from the elements. However, if climate control is your main concern, then double glazing might be the way to go.
