How to Lock a Velux Window


Aside from doors, windows are the largest entry point to your home. This makes them a potential security vulnerability. Velux windows are a bit more secure than regular windows because they have several locking options. Here are the best ones you can use to keep your home safe.

1. The Window Latch

This locking option is common and easy to use, but it doesn’t really do much in terms of making your home safer. The window latch locking mechanism works by pressing the button up or down to engage or disengage the locking mechanism. The latch automatically locks when you shut the window. When you want to install the window latch on your Velux window, you just have to screw it onto the top of your Velux window frame.

2. The Sash Cord Lock

The window sash cord lock is an excellent locking option for Velux windows because it lets you secure your window in a way that prevents intruders from opening it easily. You can also use this lock along with the slide bolt locks if you want.

The window sash cord lock works by pulling a piece of string up from the bottom of the frame on your Velux window. The string is then threaded through a small hole in the top of the frame, and it’s secured to an eyelet that’s located somewhere on the frame. The location of the eyelet depends on what style of Velux window you have.

3. The Slide Bolt Lock

The slide bolt lock is a locking option that you can use if you don’t have a sash cord lock. Sash cord locks are in place to keep intruders from opening the window by lifting up on the bottom of the frame and sliding it out of place. If you don’t have a sash cord, then a slide bolt lock will work as an alternative.

The slide bolt lock works by bolting a bar down across the bottom of your Velux window frame. The bar is usually bolted down with one or two screws. If you don’t have a sash cord, you can use a slide bolt lock along with the latch option. The slide bolt lock works just like the latch but you must install it on your Velux window frame by yourself.

4. The Screw-down Lock

The screw-down lock is used in addition to a slide bolt lock and a latch lock. It’s easy to install, but you must ensure that you have the right screws for this locking mechanism.

You need a screw that has a diameter of no less than one and three eighths inches. The screw should be long enough to penetrate the Velux window frame on both sides, preferably by at least two inches.

Make sure that your Velux window panel fits into or behind the aperture of the locking mechanism before you install it because removing it once installed will be impossible and very hard on your Velux window frame.

5. The Latch and Slide Lock Combination

You can use a latch lock to secure your Velux windows, or you can lock them with a slide bolt lock along with the latch lock. The Latch and Slide Lock Combination lets you use both locking options at once, and it works just like a chain and padlock would work.

The Latch and Slide Lock Combination lets you secure your Velux windows just like a chain and padlock, except it uses two small bolts instead of a chain. You must insert each bolt into the top of your Velux window frame, then snap them together in the middle. This combination of locks is easy to use and looks great as well.

6. Window Security Bar

.The window security bar has rubber edges that protect your Velux window from scraping. If you use this locking system, make sure that your Velux window frame is thick enough to accommodate it. The window security bar fits in between the two panes of your Velux window panel.
