Frameless doors and windows are products that are designed to provide the maximum amount of visible glass and the least amount of frame, usually aluminium. Frameless products are available as bifolding doors, sliding doors, hinged doors, windows and fixed screens. Also available are frameless glass structures such as winter gardens or glazed extensions. You will also find frameless balcony enclosures, balustrades and a broader range of glass products for internal or external use.
What you should know about frameless doors and windows.
Searches online around ‘frameless’ products can often be misleading. There is a wide variety of products on the market and what constitutes a truly frameless product can be confusing. It is worth bearing in mind some key areas where a product is marketed as frameless but may not be.
- Full aluminium windows and doors, with the aluminium frames recessed into the building structure to create a frameless appearance.
- Doors and windows that are called ‘frameless’ yet have a very thin full aluminium frame.
- Frameless doors and windows that have no visible frame on the outside only but fully framed inside.
- Beware of frameless doors and windows designed for internal use or only available with single glass.
Every door and window needs a perimeter frame of some description therefore very few products on the market are completely made of glass. Most residential frameless windows and doors will rely on an aluminium or another type of frame to provide strength, integrity and reliability, especially where opening doors or windows are needed.
Performance and specifications of frameless doors and windows.
A well-designed frameless door and window will give the expected weather resistance, security and reliability associated with their fully framed counterparts. It is very important that you check the performance of frameless glass systems. Ask to see performance testing documentation, details of the guarantee available and exactly what is covered under the guarantee.
The glass and other components found in a frameless window or door come from several external suppliers. It is not unusual, for example, for a glass manufacturer providing the double glazed units to only provide a 5-year guarantee which your installer will pass on. Therefore, some frameless products may only come with a short guarantee period. Some frameless products will come with the well-known and expected 10-year guarantee, others may only come with five or less.
The aluminium materials found on frameless doors and windows should conform to industry standards for quality and type of aluminium. Powder coated colours and finishes should come with the correct industry British or European Standard or be painted by a Qualicoat or other approved applicator.
With the minimal amount of aluminium, found in a frameless window or door you may find a more basic locking system than the typical multi-point lock on a full aluminium frame. Check what security accreditations or certification comes with the product.
