How Much Does Retrofit Double Glazing Cost?
With retrofit double glazing, instead of paying tens of thousands to insulate your windows with new double glazed windows, you’ll end up paying much less, depending on how many windows there are and the features of your double glazing. For larger homes, or for projects involving lots of upgrades to boost performance, the cost may be a little higher. Likewise, for a smaller home, and for standard double glazing features, you can end up paying less. You also have the option to retrofit one or more windows at a time as you can afford to do so. This means you’ll retain the original look and feel of your current windows because the existing timber frames remain in place. When windows are retrofitted, using Thermawoods unique patented process and tooling the single glass pane is removed and replaced by a double glazing unit (also known as an insulated glass unit or IGU) and Thermawoods patented drainage system. This is the primary advantage of retrofit double glazing: you’ll have to make a fraction of the investment you would have made with new double glazed windows but you end up with the same level of performance, plus full drainage around the IGU and you get to keep the aesthetics and character of your original windows. This is a huge bonus when you have a beautiful set of Victorian double hung windows, Georgian casement windows, or other priceless heritage gems and you don’t want to lose the charm or function. In fact, at Theramwood, we have been approved by Heritage for Grade 1 and State-Listed properties because our unique Retrofit Double Glazing system revolves around not just insulating and improving performance, but also preservation and longevity.
How Much Does Secondary Glazing Cost?
With secondary glazing, expect the costs to hover around the same price point of retrofit double glazing. The more windows you have in your home, the higher the price. The reason secondary glazing is more affordable than new double glazed windows is that, as with retrofitting, your current frame stays in place. The difference is, instead of replacing the single glaze with an IGU and drainage, you are simply attaching a second pane of glass or acrylic sheet on the inside of your current single glazing. The downside is you won’t see the same insulation benefits – secondary glazing is about half as effective as double glazing for thermal insulation. Also, there is a higher risk of moisture damage. This is because with a secondary glaze, the gap in between the two panes of glass isn’t sealed as tightly as the air space in a double glazing unit. This makes it easy for condensation to form on the inside of the glass. This moisture build-up can lead to problems like:
What about the Costs of Secondary Glazing for Sash Windows?
Secondary glazing will cost about the same amount as retrofit double glazing. So, you’ll save money with both of these options. However, there’s a major problem with secondary glazing: the windows aren’t re-weighted. Basically, you’ll end up with a second pane of glass attached to your original glass, and that will throw off your window movement and not allow it to function as it should or at all. Secondary glazing also doesn’t offer the same thermal insulation benefits as double glazing. At Thermawood, when we retrofit double glazed sash windows, we re-weight the windows to accommodate the addition of the IGU. This is a standard part of our process, and, we believe, an essential part. After all, your windows should work like new after being double glazed. They shouldn’t create new problems.
