Heralded by the call for a minimal sliding system that holds a greater glass size, Keller have delivered the new Minimal Windows 4+ system.
Still incorporating the slim sight lines clients love in Minimal Windows, the new system can hold pane sizes up to a staggering 12m² and a height of 4.5m in triple glazed units.
The tougher structure with 26mm sightlines is able to handle higher wind loads without the need for extra bulky supports, so is a great way to enjoy an unobstructed view along the high wind coast or in rural areas.
The incorporation of a triple glazed unit into these minimal sliding glass doors enables the minimal windows 4+ system to achieve much higher levels of insulation with Uw values of as little as 0.8 W/m2K.
In addition to the larger panel sizes, improved insulation and increased resistance to wind load the Keller minimal windows 4+ system has also been tested to higher results of water resistance. All the minimal windows siding door systems are put through a battery of testing at the prestigious Rosenheim Institute in Germany to put their weather resistance to the test. The Keller minimal windows 4+ system achieved a Class 8A in Water Resistance which means that it can be designated as part of the façade material of a building, particularly useful for multi-storey residential buildings.
In short, the Keller minimal windows 4+ is a great advancement in the technology of slim framed sliding door systems with ‘4+’ enhancements:
Better Thermal Performance
Larger Sliding Door Sizes
Higher Wind Loads
More Water Tight
