Enhancing Building Façades with IZOPERM PLUS A2: A Case Study of University Hospital Limerick

In a significant development for healthcare infrastructure, Minister for Health Stephen Donnelly broke ground on University Hospital Limerick’s new 96-bed block, part of a €90 million investment, set to be completed by Q1 2025. This initiative aims to bolster bed capacity and isolation capabilities. With Sisk as the main contractor, construction is underway on this vital project. Minister Donnelly emphasized the importance of this expansion for Limerick and the Mid-West. It promises to enhance patient care and facility functionality, marking an important improvement for University Hospital Limerick.

As the architectural landscape continues to evolve, the importance of robust building materials, especially in façade construction, cannot be overstated. Sisk recognized this necessity and embarked on a project integrating IZOPERM PLUS A2 non-combustible vapour control layer, ECHOSEAL ALU FR tape, VARA Seal tape and VERBOND Hybrid Adhesive into their façade design.

Interview with Paul McLoughlin

In this interview, Paul McLoughlin, Project Manager & Package Manager for the façade works at Sisk, shares his experiences and insights into the membrane application, shedding light on its successes and challenges, and demonstrating the efficacy of Partel membrane in enhancing building façades.

Q1: Can you give an overview of the membrane-related project?

A: The Partel membrane has been selected for ventilated stone façades and rendered insulation. It is a single membrane approach with the VCL providing protection against water ingress and air leakage. The membrane is predominantly fixed to a Steel Framing System (SFS) with a cement board substrate or concrete walls. We got all contractors to buy into using a single membrane system, this was very beneficial for compatibility reasons.

Q2: What specific membrane materials were used in this project?

A: We are using the IZOPERM PLUS A2 on all façade types, we chose this membrane because it met all our criteria for fire rating (B-S1-d0), vapour resistance and air tightness.

Q3: How did the membrane materials help to ensure the project’s success?

A: The design team, thermal specialist and contractors bought into the one product, which made life very easy once we agreed on the product.

The next day delivery is very helpful when contractors suddenly run out of material.

Q4: Can you provide specific examples demonstrating the efficiency of the membrane materials in this project?

A: Visual examples demonstrate how the membrane is effectively protected against water ingress and air leakage.

Q5: How did the use of membrane materials impact the project’s timeline and budget?

A: Although the design at the tender stage had a breather membrane externally and an air tightness membrane internally, on review of the drawings with the air tightness contractor advised to go for a single membrane externally is the most suitable for this project. It was a collective decision with the design team to use the Partel IZOPERM PLUS A2 after a considerable review period of various membranes. There will be a saving for the client with the external membrane and a time saving for the contractor installing the internal air tightness membrane over four floors.

Q6: Could you provide a quick analysis of the project and how Partel played a part?

A: Partel provided WUFI analysis to confirm the dew point was outside the VCL and there was no risk to interstitial condensation. Compatibility testing was carried out between the tapes and mastic with our substrates. Partel was very proactive in the design process answering all technical questions.

Partel assisted in knowledge sharing/training when we commenced the first installation of the membrane. The regular inspections have been beneficial for contractors and subcontractors.

How IZOPERM PLUS A2 Can Benefit Your Project

Incorporating IZOPERM PLUS A2 into your building project offers a multitude of advantages. This non-combustible vapour control layer, boasting an A2-s1,d0 Reaction To Fire classification, is designed to safeguard building elements from degradation while effectively limiting the movement of water vapour. By preventing interstitial condensation, it ensures the longevity and integrity of your structure.

Compatible with Partel ECHOSEAL fire-rated adhesive tapes, IZOPERM PLUS A2 provides an unmatched level of fire safety, making it suitable for a wide range of applications, including high-rise constructions. Its exceptional vapour resistance, airtight performance, and resistance to water penetration guarantee optimal performance in diverse environmental conditions. Furthermore, the reflective properties of IZOPERM PLUS A2 contribute to enhanced thermal performance by reducing interior heat loss.

From residential to commercial buildings, timber to steel-framed constructions, and warm to cold roof applications, IZOPERM PLUS A2 offers versatility and reliability. With compliance to UKCA & CE standards, you can trust in its adherence to regulatory requirements and industry standards.

Summary

In conclusion, the integration of Partel membrane into the University Hospital Limerick’s façade project stands as a great example of the transformative impact of innovative membrane solutions in enhancing building performance, durability and fire safety. Paul McLoughlin’s insights highlight the project’s success in addressing critical challenges such as water ingress, air leakage, and fire resistance. McLoughlin’s experiences not only shed light on the journey of this specific project but also serve as a guide for future endeavours in similar structures, emphasizing the importance of collaboration, material selection, and adherence to regulatory standards. With its proven track record in enhancing building façades, Partel membrane emerges as a reliable partner in the pursuit of excellence in construction and architectural design.

We sincerely thank Sisk for graciously providing the relevant information & case study review.
