Application

Proteus Low-K is used within an inverted roofing system in conjunction with the following inverted insulation boards:

Proteus Pro-Therm XPS.
Proteus Pro-Therm EPS.
Proteus Pro-Therm XPS Upstand Board.
Proteus Pro-Therm Non-Combustible Upstand Board.

Proteus Low-K is suitable for use with the following waterproofing systems:

Pro-BW® Plus.
Pro-BW® LO.
Proteus Hot Melt®.
Cold Melt®.

Description

Proteus Low-K is a breathable waterproof membrane which minimises the cooling effect associated with rainwater flowing down through the insulation and draining away. This provides improved U-Values, reducing the required insulation thickness.

Features and benefits:

Improves the performance of inverted insulation, for any required U-value.
Waterproof.
Breathable.
Easy to handle.
Lightweight.
High water vapour permeability.
Strong micro porous polypropylene.
Recommended for use with Proteus Pro-Therm XPS Plus, Proteus Pro-Therm EPS Plus Premium and Proteus Pro-Therm Inverted VIP.
Resists attack by mould and fungus growth, and will not encourage insect attack.
UV–resistant and can be safely exposed on site for a period not exceeding four months.
