Designing a building envelope: 2 critical questions

When it comes to specifying interface sealing membranes, regulatory compliance and top performance around fire safety are essential

In association with
The Obex Cortex 0200FR Class A membrane is the first and only facade-sealing membrane to possess a Class A fire classification so it is also the first to meet the full requirements of Regulation 7.
The Obex Cortex 0200FR Class A membrane is the first and only facade-sealing membrane to possess a Class A fire classification so it is also the first to meet the full requirements of Regulation 7.

When considering the design of a building envelope, specifiers need to know that the materials being proposed are fully compliant with the building regulations and that they have been tested to the correct performance standards.

The new Obex Cortex 0200FR Class A interface sealing membrane (ISM) has quickly become the obvious choice for designers and contractors who insist on high performance and regulatory compliance.

Class A fire classification and Regulation 7 compliance

Fire safety is a critical factor in the design and construction of building envelopes.  The 0200FR Class A membrane is the first and only facade-sealing membrane to possess a Class A fire classification, meaning it is also the first to meet the full requirements of Regulation 7.

This means that contractors can now install a truly Class A through-wall envelope system, which includes all membranes, as Obex also supplies compliant Class A breather membranes and vapour control layers.

EN 13984 performance standard

Obex Cortex 0200FR has passed the EN 13984 performance test, which evaluates key aspects such as water permeability.

This test requires resistance to a water pressure of 2kPa for 24 hours (breather membranes only require 2kPa for two hours). This is an essential test for those membranes that are installed to perform a water and airtight seal around windows and along facade interfaces.

Manchester reclad project: Cypress Place and Vallea Court

The Cypress Place and Vallea Court project in Manchester involved the refurbishment of two high-rise residential buildings.

The Obex Cortex 0200FR Class A membrane and the Cortex 0210FR Class A paste adhesive are currently used on this project.  The adhesive also has a Class A fire classification so the two products used together provide the perfect solution for window and interface sealing.

The contractor specified these two products for the window and interface sealing details as it is the only facade sealing system available with each component achieving Class A fire classification. 

At a time when government regulations are becoming more stringent, architects are looking for materials that perform their primary function to the relevant standard and achieve fire safety compliance. 

The Obex Cortex 0200FR Class A membrane is the perfect solution for meeting modern-day regulatory and performance requirements.
