What is a VELUX 2in1 window?

First things first:

What exactly is this VELUX 2in1 window people have been raving about?

Here’s the scoop:

The VELUX 2in1 window is a unique type of roof window that combines two windows in one unit within a single frame – one fixed window and one top-hung or centre-pivot window, depending on which option you prefer. So, you can enjoy the benefits of two different types of VELUX windows in one product.

The top-hung or centre-pivot window is perfect for providing ventilation, while the fixed window is ideal for letting in natural light. With the VELUX 2in1 window, you don’t have to choose between the two – you get the best of both worlds.VELUX 2in1 centre-pivot roof window


What are the benefits of a VELUX 2in1 window?

Now that we have a clearer idea of what the VELUX 2in1 window is, let’s take a closer look at its amazing benefits.

More natural light

We’ve already touched on this, but it’s worth delving a bit deeper. The fixed window allows for more natural light to enter your home, which can make a big difference in the overall look and feel of your space.

The thing is:

Natural light has been shown to have a range of benefits, including improving mood, boosting productivity and promoting better sleep.

This is huge, as you end up getting twice the amount of natural light you normally would with most other roof window types. And since natural light is one of the most important considerations for buyers, you can see why the new VELUX 2 in 1 is the talk of the town. Thanks to this tidy new design, you can literally let the sunshine in.

But wait! There’s more:

With the top-hung or centre-pivot window, you can enjoy increased ventilation in your home. This is particularly useful during the warmer months when you want to let fresh air into your home.

Improved energy-efficiency

VELUX 2in1 windows are designed to be energy-efficient, which means that they can help you save money on your heating and cooling bills. With a range of glazing options available, such as double-glazed as well as VELUX triple glazed windows, you can choose the one that best suits your needs and budget.

Easy maintenance

The VELUX 2in1 window is remarkably easy to clean, with a simple wipe-down process that you can do from inside your home if you opt for the centre-pivot option.
