Velux Windows in Henley-on-thames

Velux windows actually refer to one brand of roof window, which are windows that sit in your roof space and allow light and ventilation into your loft. But how do you install a Velux window? If you’re a competent DIYer, it’s not as difficult as you might think.

You can normally install roof windows entirely from the inside, so you don’t need to get up on your roof or hire costly scaffolding. They come with detailed installation instructions, so as long as you follow them you shouldn’t have much trouble.

Before you start, you’ll need to read up on the Building Regulations and Planning Permission laws. Speak to your local Building Control department if you have any questions.

Firstly, prepare the opening by removing enough tiles or slates from the roof. There’s no need to go out on the roof – access them by cutting away the felt underneath which will give you access to the tiles and battens. Cut away one of the battens from under a tile, then you can slide all the tiles into the roof space. You’ll need to cut away the roof timbers to make the right size opening, then add more timbers to strengthen the ones that are left.

Next, remove the opening sash from the new roof window then fit the frame into the new opening using the brackets provided with the window. Then fit roof flashing between the new window and the roof so you don’t get any leaks. Then lay your tiles back in position around the new Velux window; you’ll probably have to cut some to shape which you can do with an angle grinder. Always cut them on the ground, not in position on the roof.

Lastly, fit the sash back onto the window and you’re done!

If this sounds like too much hard work, plenty of window installers will be able to help you fit a Velux window and will probably be able to provide a much cleaner finish.

While it sounds like it could be difficult to plasterboard around a Velux window, it needn’t be. As long as you have the right tools and materials, you should be able to plasterboard around your roof window easily and make good ready to be skimmed. When you or a tradesperson has fitted your Velux window into your roof, you’ll probably need to plasterboard over it to create a good ceiling. To do this, you’ll need:

• Plasterboard sheets – make sure you measure your room so you know how much you’ll need
• Screws to secure the board in place
• Drill
• Hammer
• Straight edge and pen knife to score the board before trimming
• Fine toothed saw the cut the plasterboard

When you’re ready to plasterboard around your roof window, make sure you’ve cleared enough space to work in. Then you can begin by cutting your plasterboard to size using your straight edge and pen knife to score, then your saw to get a clean cut. A common way of plasterboarding around your Velux window is to use the groove on the window frame to hold one edge of the board, then screw the other edge to the battens on the ceiling. People often use drywall screws these days as they have a better grip of the plasterboard as they drive through. You’ll need to use a drill to screw these in. However, you could use plasterboard nails, which are galvanised to stop rusting. When you’ve done this, you can then skim the walls or ask a plasterer to do it for you. Plastering, while it looks easy, is a tricky skill so it’s always best to ask a professional to do it.

Velux windows are a great way to add lots of light to your loft space. Velux is actually the name of a brand of roof window – not to be confused with roof lights, which are usually installed on flat roofs, or skylights, which are normally used to add natural light into a room without being able to open it. Roof windows open like regular windows and are fitted within your roof. But how much are Velux windows? Whether you choose a Velux window or another brand of roof window, they’re not cheap. Since they require special installation, including cutting roof timbers and replacing them to keep the structure strong enough, they take longer to install than a normal double glazed window. It can take up to a day to install a large Velux window, and it could set you back anywhere between £1,600 and £2,000. If you only need a small roof window in an area like a bathroom, you can expect to pay up to £1,300 for it to be fitted. Usually, there won’t be any need for scaffolding or towers because Velux windows are designed to be installed from the inside of your home. However, it’s worth setting aside an additional £500 in your budget in case unexpected problems occur and an installer needs to get on your roof to finish fitting the window. All of these prices are based on a standard roof window without any additional features. If you want to be able to control your windows with an electric switch or remote, this could set you back as much as an additional £400. For extra-low energy glass, you can expect to pay up to £200 more.

Velux windows, or roof windows, are very easy to clean. Regular cleaning helps to keep them looking bright and shiny for years to come. So how should you clean Velux windows?

If you want to clean the air filter, you can remove it and wash it with your normal household cleaners. Velux windows have a cleaning position, so rotate and secure it into this position then remove the filter. You should be able to buy new filters from the manufacturer of your roof window.

To clean the outer pane, there’s no need to lean out of the window and risk falling out. Simply rotate the sash (the opening part) 180 degrees and secure it into position. Then you can clean the pane with a soft, lint-free cloth, sponge or squeegee and clean water. If you live in a hard water area, add some detergent to the water and wipe the window dry when you’re finished. You can also use normal non-abrasive household cleaners.

It’s recommended that you clean the flashing around your roof window at least once a year. You can use a brush to do this. This will allow rainwater to flow freely and stop any leaves from collecting.

If you’re in any doubt about using certain cleaners on your Velux windows, get in touch with the manufacturer who should be able to help. You can also do a patch test on an inconspicuous area if you’re unsure.
