The harmony of double glazed framing systems

Life is not one size fits all. And neither are your designs. Enter MAX™.

MAX, EDGE Architectural’s double glazed range, adopts all the products from the U-MAX™ range in non-broken form, complemented by additional frame selections. Like U-MAX, MAX offers an array of interchangeable systems and door and sash elements to provide a complete, highly energy efficient range of products.

Use MAX and U-MAX together on a project for a seamless transition across facades, selecting the correct product for the required energy rating and the desired visual impact. The result is cost control in harmony with stunning aesthetics throughout the project.

The outer frame elements of MAX generally allow either a narrow 44mm or 50mm face, but can incorporate U-MAX frame members which are 60mm. Suites include 100mm centre glaze and 150mm offset glaze, where the glass set back is in the same plane. MAX 150mm includes several wide pocket, sash and door options.

Technical details for suites in the MAX™ double glazed framing range

The EDGE Architectural MAX double glazed systems have been designed to self-drain within the system via a patented Watershed component in the transom, which is traditionally the area most prone to leakage in commercial systems.

Most other commercial systems attempt to deal with drainage through ugly external drain slots or rely on silicone to stop water entry.

Using “top loaded” high performance, shrink resistant, co-extruded wedges, the system allows easy in-factory fitting of backing wedges and easy fitting of wedges on the side from which the system is being glazed.

Wedges are colour coded according to thickness for ease of identification, refer to the chart in the MAX technical manual.

Commercial window systems are designed for drainage through the system. Horizontal members act as “gutters” collecting water and allowing it to flow to vertical members, which act as “down pipes”.

It then becomes mandatory to adequately flash frames at the sill – this can be done via a folded flashing, impervious rebate, but usually by the use of a subsill.

The subsill allows easy preparation for an opening and ready access to subsill fixings so they can be appropriately sealed prior to frame installation.

A subsill is fitted with a stop end, which contains water within the subsill and is fitted and sealed during the fitting of a subsill. Without this, water would run to the ends of the subsill and leak back into the building.

Sub heads are used to allow for either vertical movement or as a more efficient means of installation, especially in above ground installations where it might be desirable to install frames from inside.

Sub frames, likewise, can be used in this situation, but are especially needed when ventilated cavities (like cavity brick) where there is airflow that may allow water to be driven over subsill stop ends, or it is difficult to contain water within a window opening.

It must be remembered that all window installations require continuous internal seal and the use of subsills and sub frames are especially useful in achieving this.
