At IDM Doors, we take immense pride in supporting housing associations across Wales and the South West with high-performance building envelope upgrades. Our most recent project at Llys Coch, Cowbridge Road West, Cardiff—completed on behalf of Hafod Housing—demonstrates how combining fire-rated cladding with modern, high-durability uPVC roofline systems can transform both the safety and aesthetic appeal of social housing developments.
Here is a closer look at the scope of work, technical specifications, and benefits delivered to Hafod Housing and its residents.
The Project Scope: Llys Coch, Cardiff
Llys Coch is a multi-dwelling residential property requiring targeted exterior refurbishments to enhance thermal performance, weather protection, and stringent fire safety compliance. IDM Doors was appointed to install a full exterior refurbishment package, including:
Fire-rated composite wall cladding across primary elevations and upper-tier dormer faces.
Full uPVC roofline replacement, including low-maintenance white fascias, vented soffits, and heavy-duty black rainwater drainage systems.
Dormer window cheek & overhang detailing, offering clean lines and complete weatherproofing.
Under-canopy ceiling cladding, providing bright, durable, and clean communal walkthrough spaces.

Why Fire-Rated Cladding is Essential for Social Housing
Ensuring life-safety compliance is top-of-mind for housing providers following updated UK Building Regulations and fire safety legislation. External cladding on residential properties must satisfy rigorous fire performance criteria to prevent flame spread across building facades.
For the Llys Coch project, our fire-rated cladding system was chosen specifically to meet these requirements while delivering an attractive, textured timber-effect finish.
Key Benefits of Our Fire-Rated Cladding:
Certified Fire Performance: Engineered to strictly resist surface flame spread, protecting multi-occupancy structure interiors.
Weather & UV Resistance: Built to withstand the damp, changing climate of South Wales without warping, splitting, or fading.
Low Maintenance Requirements: Eliminates the ongoing costs of sanding, staining, or painting traditional timber weatherboarding.
Thermal Efficiency: Adds a defensive thermal layer to the building fabric, lowering heat loss for residents.
Modern uPVC Roofline Systems Built to Last
Alongside vertical cladding, the roofline forms the first line of defence against water ingress, wind driven rain, and roof cavity dampness.
The original roofline elements at Llys Coch were replaced with precision-engineered uPVC fascias, ventilated soffit boards, and seamless black gutters.
Why Upgrade Rooflines on Planned Maintenance Contracts?
-
Superior Water Management: High-capacity black rainwater guttering directs runoff away from brickwork, preventing structural damp.
-
Preventing Roof Space Condensation: Vented soffits ensure continuous airflow within the loft space, mitigating damp and timber rot.
-
Enhanced Kerb Appeal: Dark charcoal exterior cladding paired with brilliant white fascias and sleek black guttering creates a contemporary, clean finish.
-
Long-Term Cost Savings: High-grade uPVC guarantees decades of protection with minimal upkeep, providing exceptional long-term value for social landlords.
Expert Project Delivery with Minimal Resident Disruption
Working within active social housing developments requires careful planning, strict safety protocols, and proactive communication. Scaffold towers and safety rails were erected across the Llys Coch elevation to allow safe access to dormers and upper rooflines without impeding ground-level access for tenants.
IDM Doors managed the installation process from initial site survey to final sign-off, ensuring:
Full Compliance: Complete adherence to current fire safety, building control, and health and safety standards.
Resident-Centric Scheduling: Work planned to minimize noise, access restriction, and daily disruption for tenants.
Precision Craftsmanship: Flawless flashing, leadwork integrations, and corner trims for long-lasting structural integrity.
