Posted by Lawrie Fraser on 31st March 2023

VELUX windows are a popular brand of roof windows that provide natural light and ventilation to homes. While they are built to last, accidents can happen, and your VELUX window may crack. Here's what you should do if your VELUX window cracks.

Here is what to do if your VELUX window cracks: 

  1. Assess the damage
  2. Contact YARD
  3. Remove the damaged VELUX window 
  4. Install the new VELUX window
  5. Test the VELUX window 
  6. Maintain your VELUX window correctly

1. Assess the damage:

The first thing you need to do is assess the damage. Look at the crack and determine how severe it is. We always recommend replacing the roof window if the pane cracks to ensure your home is completely watertight and energy efficient. Some VELUX windows may be subject to thermal cracks. Thermal cracks occurs when the difference in temperature is high within a concrete structure or any surrounding supporting building materials. The high temperature makes particles within either the gas or the pain to implode, usually the window will not shatter. However, thermal cracks may appear as a hairline crack or a spider-web looking crack.

2. Contact YARD:

If you need to replace the window, the next step is to contact VELUX. They will be able to provide you with a replacement window that is the correct size and type for your specific window. You can contact YARD by phone, email or through our website. It is important to know, some VELUX windows are subject to recall from VELUX with an inner pane fault. The inner glazing on the window can be faulty and may implode which could cause injury. Cold temperature is a known factor in making these windows implode. Window models effected may be:

C width windows – Pane width 39cm.

F width windows – Pane width 48cm.

M width windows – Pane width 61cm.

Please contact VELUX immediately if your window begins with this code that has imploded or cracked. If your window is found to be at fault, VELUX will replace the glazing unit of the window for free.

3. Remove the damaged VELUX window:

Before you can install the new window, you need to remove the damaged one. This can be done by first removing the trim around the window. You will then need to carefully remove the window from its frame. Please be careful when removing this VELUX window as the pane may shatter and cause injury with prompt movement or any forceful movement.

4. Install the new window:

Once you have removed the damaged window, you can install the new one. Follow the instructions provided by VELUX to ensure that the window is installed correctly. You may need to apply sealant around the frame to ensure that the window is watertight. You can view our guide on how to install a VELUX window here.

5.Test the new window:

Once you have installed the new window, you should test it to ensure that it is working properly. Open and close the window to make sure that it operates smoothly. Check to make sure that it is properly sealed and that there are no leaks.

6.Maintain your VELUX window:

To prevent further damage to your VELUX window, it is important to maintain it properly. Clean the window regularly to prevent dirt and debris from accumulating on the glass. Inspect the window periodically to ensure that there are no cracks or other damage. You can read our guide on roof window maintenance here.
