Height-adjustable glass barrier

Height-adjustable glass barrier

Alu Flex is a versatile and robust glass barrier with a protective top panel which can be raised and lowered as required. A chill wind blowing? Simply pull up the glass section to create an effective windbreak so you can sit in comfort. A warmer day? Lower the glass section and enjoy the summer breeze.

Functional & stylish – with options

With our height-adjustable glass barrier, you can defy the weather gods and enjoy your patio for longer. Our attractive design helps to frame the outdoor area and blends in seamlessly with your garden. You can even add an awning to create a conservatory.

Selected options:

  • The aluminum posts are available in the standard colours of untreated (aluminum), white and black, but you can also choose which RAL colour suits you.
  • Height: Lowered position/raised position: 800/1300 mm, 900/1500 mm, 1000/1700 mm, 1100/1900 * mm or 1200/2100 * mm (max. Width 2000 mm).
  • Width: Max 2200 mm **

* For installation of more than 2m above ground level, the height of the lowered position of the railing must be at least 1100 mm.
** Please note that the maximum width is subject to the prevailing wind conditions and desired installation height. This applies to fixed barriers and standard height-adjustable sections.

You make your selections in our design tool.

Adjustable height – easy

The inbuilt barrier counterweight offers the advantage of smooth and easy control and requires no force to change the height. Even a child can change the barrier’s position. This also enables precise control of the barrier’s height, to suit your needs and the conditions.

Easy to customise and order through our design tool

With our easy to use design and ordering tool, simply add the dimensions and tailor the design to meet your taste or needs. Your choices will be displayed as both a 3D image and drawing, so that you can feel completely confident about how it will look before you order. If you save your design, you can log in again and adjust the size and features at any time. You can also have the quote sent to your email address, to give you time to reflect on your decision.
