INCA Case Study: 84 Tregwilym, Rogerstone

The Background to the Project

Newport City Homes required an External Wall Insulation (EWI) solution for dwellings that were undergoing full house refurbishment. It was important that the existing stone and brick patterning, including the quoins, were faithfully replicated. The condition of the dwellings resulted in the need for partial rebuilding of the walls and a complete re-roof.

The Solution & Specification

The Structherm ArtBrickTM system was selected, as this provided the ability to match the existing combined stone and brick finish, retaining the heritage of the building and matching the surrounding area.

Mineral wool insulation was also chosen to meet client requirement for an A2 Fire rated system, due to the building being multiple occupancy.

The Installation & Challenges on site

Extensive dubbing out and localised areas of increased insulation thickness were required to address undulations, bowing and uneven line and level of the walls.

Stone samples were produced in-house and subsequently presented to planners, to gain approval for the project to go ahead.

Problems Overcome

Structherm’s ArtBrickTM provided a suitable and highly satisfactory finish on what was a complex combined stone and brick substrate.

The End Result

The end result is almost completely indiscernible from the original look of the dwellings and faithfully replicates the original character of the building at Tregwilym, Rogerstone, as shown in the black and white photos. When looking at the before and after photos it is difficult to tell which was which, therefore achieving a key aim of the project.

The thermal insulation and comfort levels have been significantly raised, making it more economical to heat and a fit-for-purpose homes for future years.
