How do I choose good roof windows?

Roof windows are a great way to light up the attic. Thanks to this we gain additional lighting and an interesting arrangement. What should you consider when choosing a roof window?

What should you consider when choosing roof windows?

1. Adequate room illumination

Consider roof windows with large glazing units which bring more light into the room. We spend almost 90% of our free time indoors.

2. Choosing the right way to open a roof window

You can buy roof windows with different opening systems – this parameter determines the comfort of using roof windows. You can choose between:

• top hung,
• pivot – they can be rotated 180° and locked. This makes them easy to keep clean;
• top hung and pivot windows,
• balcony windows – modern double sash windows with two sashes forming a balcony. The upper sash opens upwards and the lower sash opens downwards. Side rails are integrated with the lower sash and slide out during opening – this provides safety when using the window.
• the window is equipped with a raised axis of rotation.

3. Supporting ventilation of rooms

Air exchange is very important to maintain the correct level of humidity in the room. That is why it is important to choose roof windows that will ensure trouble-free ventilation and will have vents supporting ventilation.

4. The right material

Depending on the purpose of the room you may choose:

• aluminium-wooden windows – wooden windows shielded from the outside by aluminium profiles;
• aluminium-plastic – made of PVC, reinforced with steel profiles inside and shielded from outside with aluminium profiles.

Aluminum-plastic windows can be used in any type of room

Wooden-aluminium windows are not recommended for rooms with increased humidity such as kitchens and bathrooms.

4. Roof pitch

When choosing roof windows, stick to the rule: “the lower the roof pitch angle, the higher the window height should be” – this makes the roof window more convenient to use and better illuminates the room.

5. How to open the window

Handle located at the bottom of the window ensures comfortable use – it is always within easy reach.

Energy efficiency of roof windows

According to the latest requirements concerning thermal efficiency, you should choose roof windows meeting the WT2021 standard – windows with a heat transfer coefficient not exceeding 0.9 W/m2K, and in skylights not exceeding 1.1 W/m2K. This standard is met by 3-pane windows. Such windows have a built-in ventilation system, which allows ventilation of rooms – even when they are closed.

Intelligent roof windows

Increasingly popular are electronically controlled windows – either by remote control or automatic programming. Communication between the window and the remote control can be either wired or wireless (using radio waves).

Shuttering for roof windows

Modern roof windows effectively prevent heat escaping, which is why it is so important to use roof window shades – rooms in the attic heat up very quickly in summer.

We recommend solar awnings which are powered by solar energy and can be controlled by remote control or smartphone. By controlling awnings remotely, you can create the ideal conditions in your attic.
