In the unfortunate event of a problem occurring with your installation, contact the installer of your products in the first instance.


I have a mark on my windows that I can’t remove with soap and water, can you recommend a product?

Stains or marks on PVC windows or doors that cannot be removed with warm soapy water may be removed with a non-abrasive domestic cleaner. However, these may not be used to excess as they may affect the gloss finish. For products with a colour or woodgrain finish, you will need to contact your installer to recommend a product for cleaning the products.


I live in a very noisy area, can you recommend a product?

TwinSash has superb thermal and acoustic performance with sound reduction up to 50dB. Triple glazing is also an option. We recommend talking to your local installer.

What is the best U Value or energy rating I can achieve?

VEKA Group systems are designed to achieve the best energy ratings they can but this depends on the overall specification and the requirements or capabilities of the installation. Outer frame size, reinforcing specification & glass type all affect the overall U value & energy ratings. On the other hand it may not always be beneficial to specify the highest rating as it may exceed the capabilities of the property or be in a location where no benefit is gained. For advice please speak to a qualified surveyor or recommended installer. Click here to find your nearest installer


I need a part number and I only have a description?

Fabricators can access wall charts for VEKA or Halo parts here, if you are not a fabricator and need a part number please contact a member of the technical team  email technical@veka.com or call 01282 725361.

What is the correct installation method?

It is important that any frame, window or door is installed to the appropriate British standard.  Additional installation advice is available to installers for some of our more specialist systems but for generic please refer to the GGF (Glass & Glazing Federation) website. Visit here for more information. 


How many chambers do VEKA & Halo sections have?

The number of chambers a profile system has affects how the U Value or energy rating is calculated but does not dictate it. A three chamber system can achieve a comparable range of results of a five chamber system dependant on the overall specification or mix of components used. For advice on the best system to meet any requirements please ask a suitably qualified surveyor or installer. Click here to find your nearest installer
