Well-constructed sash windows that are not showing any signs of wear and tear should not be draughty. However, old sash windows will be worn, and wherever there are gaps, the cold air sneaks in. This will prove costly in terms of heating bills, and the chilly draughts will still make their presence felt.
Draught proofing may be a solution, but you should also check out the type of wear that initially caused draughts and the condition of the wood. For example, if there are signs of rot, your DIY draught proofing is just a stop-gap measure, and you will still need to repair or replace your windows at some time.
Draught Proofing Sash Windows Can Be a Comparatively Easy DIY Job
Almost anyone can do sash window draught proofing. There are several ways to approach it, but some methods will permanently seal windows shut. Since ventilation is important for indoor air quality and to cool your home in summer, some other means of ventilation should be present if you decide to seal your sash windows completely.
Options for draught proofing sash windows include:
- Silicone sealants
- Temporary window sealers
- Weather strips
The main challenge you face is the fact that window sashes slide over one another. If you choose self-adhesive weather strips, for example, you will be able to open and close your sash windows, but the strips will not last long.
Silicone Sealant as a Way to Draught Proof Sash Windows
Silicone sealant is the DIY home fixer’s best friend. It’s versatile, and it seals gaps beautifully. However, it will glue your windows shut, and when it starts getting ragged or discoloured, it is hard to remove.
If you rarely or never open the sash window in question anyway, sealing it closed is a viable option, and the sealant will be fairly unobtrusive as long as you apply it neatly. In terms of draught proofing, it is hugely effective - after all, you are able to seal every gap there is against the smallest breath of cold air. However, do consider what you will do in the event of a fire. It may be difficult to open the window if it is your only means of escape.
Using Weather Strips to Cut Out Draughts From Sash Windows
Weather strips are almost as easy to apply as silicone, and they will allow you to open and close your windows. You will apply them in two stages. First, the metal or plastic strips are stuck in place. Next, the pile or brushes slot into the strips. This solution works rather well and looks neat, but won’t last very long if you like to open windows fairly regularly. The adhesive will peel away fairly quickly due to the way sash windows operate.
Temporary Sealants
There are specialised sash window sealants specifically designed for DIY use. We were quite impressed by Gapseal, a product that acts as a temporary sealer. It will hold until you open the window, and after that, you will have to reseal it. This makes it a good solution for excluding draughts during the chilly winter months, but applying it every year may become a repetitive chore.
Retrofit Double Glazing
Since we are talking about energy efficiency and a cosy home, double glazing is an essential consideration. Older sash windows may not have it, and switching to double-glazed panes will make an enormous difference.
This will be quite costly, and you may run into problems owing to the thickness of double glazing, which older sash windows are not made to accommodate. Depending on the condition of the window frames, it may be possible to adapt them. However, replacing your sash windows may be the most practical solution.
Professional Draught Proofing Versus Replacing Windows
Professional draught proofing is a step up from DIY draught sealing. The seals are made to fit securely onto the windows, and you need only replace the brushes from time to time. However, replacing your sash windows can be a better option.
