Slim Curtain Walling

Our slim aluminium glass façade system is essentially a curtain walling system especially designed for residential or luxury architectural design.

The ultra-minimal frame of the façade system creates long elevations of glass dissected with aluminium frames of only 35mm wide. This slim framing section rivals the sightlines of frameless structural glass!

Using thermal break technology the glass facades can achieve high levels of thermal performance and are able to hold either a double or triple glazed unit as required. The Super Insulating thermal break with a triple glazed unit has been PassivHaus Certified.

Single Storey Glass Walls

The aluminium façade system has been designed for single storey walls of glass for ribbon windows or long runs of minimally framed glass, although these ‘storeys’ can be of significant height.

Each glass unit within the glass elevation can be up to 8m2 with a basic transom of 70-155mm deep. Even larger glass sizes of 13m2 are possible with the heavy duty transoms of 130-155mm deep.

The resulting system is the perfect option for those looking to create large elevations of fixed glazing with minimal framing.

FWS 35 PD at The Showroom

This specialist slim framed curtain walling system is perfectly suited for residential and architectural designs. This luxury system installation is the first of its kind in the UK, available for viewing at our showroom in Amersham. This new space is also available as a meeting room, fully walled with the thermally insulating glass wall system.


Glass Specification

The glass specification for each installation of these façade systems will need to be determined depending on the height of the glass elevation and the wind load of the project.

A typical glass specification would be 6mm toughened inner and outer with an argon gas filled cavity. Additional glass options such as solar control coatings, low iron glass or decorative glass finishes are easily integrated.

The maximum size of each glass unit is determined by the weight of the glass unit to a maximum of 250kg using basic transoms and 400kg using heavy duty transoms.

Frame Design

The slim aluminium glass façade is a non-ventilated façade system with minimal framing. The vertical sightline of the system is 35mm with a internal box section of various depth depending on wind load and glass weights.

Basic Transoms for glass units of 250kg or less can be 70-155mm deep. Heavy Duty Transoms for glass units of up to 400kg are 130-155mm deep.

This glass façade system has two thermal break options:

SI Thermal Break = Uf value 0.88 W/m2K with Passivhaus Certification

HI Thermal Break = Uf value 1.2 W/m2K
