23 Sep W is for… windows
With only a few weeks left before the end of our A to Z loft conversion guide, we’re now getting to the trickier letters of the alphabet.
When you’re converting your loft, it is likely that you’ll want to install windows, not only to let in plenty of natural light and to get a great view, but also for ventilation purposes. So today we’re going to take a look at windows and the different options available to you.
You will not usually need planning permission for the following:
– Repairs and maintenance work on existing windows and window frames
– Installation of new windows that look similar to those of the existing house
If you’re installing new roof lights or sky lights, you will not need to apply for planning permission as long as:
– They will not extend more than 150mm beyond the plane of the roof slope
– If they are installed in the side of the roof slope, they will have to be obscure glazed and either no higher than 1.7m above the floor or non-opening.
Note: those living in a listed building may be required to apply for planning permission before starting on any of these works.
Building standards for replacement glazing
If there is already a window in your loft area and you wish to replace it, there are certain regulations that you will have to comply with. These include ventilation, fire safety and thermal heat loss measures.
Depending on what you are planning to use your newly converted loft for, different levels of ventilation will be required. Those rooms that will naturally produce more steam and condensation (kitchen, bathroom, utility room) will require greater levels of ventilation which can be achieved with a combination of windows and mechanical fans.
You may be required to install fire resistant windows to prevent the risk of fire spreading to adjacent houses in the event of a fire. What’s more, the loft window may also be needed as a means of escape during the event of a fire. For that reason, the size of the escape window is important. Both the width and height should be equal to or greater than 450mm, with an openable area of no less than 0.33m². You’ll probably only need one window like this in your loft room.
Thermal heat loss
The more action you take to minimise heat loss from your house, the more energy efficient it will be overall. This will result in lower energy bills so it is worthwhile to look into preventative heat loss measures, especially where windows are concerned. There are double glazing and triple glazing options available nowadays which can help to reduce heat loss.
