    Proteus Pro-Felt®


Proteus Waterproofing was called to survey and assess the current roof condition on this residential block of flats.

Product brief:

Core samples showed the existing insulation was not thick enough to meet the current insulation building standards and secondly the insulation was found to be wet from water ingress. Therefore the only course of action was to strip off the roof covering and insulation, taking the roof back to the timber deck.

High Performance Waterproofing

The deck was checked and found to be sound before installing a new Proteus Pro-Felt® Built up system, including new insulation to bring the building up to current building standards. The deck was primed with Pro-Prime® SA, Proteus Pro-Felt® Self Adhesive Underlay was then used as a vapor control layer, before a Proteus Pro-Therm Hybrid Insulation Scheme was fully bonded, including non combustible insulation over partition walls, Proteus Pro-Felt® 3mm Plain Underlay was then fully adhered to the insulation, followed by a final installation of Proteus Pro-Felt® Ultima Plus Fireguard.

Proteus Waterproofing worked closely with the Proteus Approved Contractor to ensure the project was completed to a high Standard.
