Ideal for Data Centres & Technical Facilities

Our white wall systems combine pre-finished steel facings with a non-combustible mineral wool core to create a fast-track building envelope and reliable fire-rated internal separation. The result is a predictable, high-quality installation that supports programme certainty, strong passive fire strategies, and long-term durability.

Our Trusted Manufacturer

GA Interiors works with leading insulated panel systems from Paroc Panel System, recognised for delivering high-performance structural sandwich panels.

Their systems pair durable steel facings with a non-combustible stone wool core, providing insulation, acoustic control, and fire performance, while the composite construction allows long spans and efficient fixing.

Key features

High-performance panels combining thermal, acoustic, and fire protection with steel facings and stone wool cores for strength and durability.

Fire-Resistant & Non-Combustible Materials

Our panel systems are designed to provide maximum fire safety, using materials that meet the latest regulations and ensure building protection.

Durable & High-Performance

Designed to withstand weathering, provide thermal efficiency, and protect your building for the long term.

Expert Installation & Compliance

Fully compliant with the latest fire safety regulations and building standards, giving you complete peace of mind.

Fire Safety for White Wall Systems

It is important to distinguish reaction to fire from fire resistance. Reaction to fire (e.g., Euroclass A2 s1,d0) shows a product’s contribution to fire and smoke, while fire resistance (EI – integrity & insulation) indicates how long a wall can contain fire and limit heat transfer. Data centres often require both low fire contribution and strong compartment performance.

Maintaining Panel Integrity

Composite wall panels are engineered to maintain continuity of performance. Correct joint compression, sealing and fixings are essential, especially for data centres where airtightness, smoke control, and fire compartment are high priority.

Compliance & Safety First

All our white wall and sandwich panel installations strictly follow current fire, thermal, and acoustic regulations, as well as industry best practices, ensuring reliable performance and complete peace of mind on every project.

Multi-million pound drylining package

“Worked with G A Interiors on a multi- million pound drylining scheme for a new
palliative care hospice. The team at GAI were a pleasure to work With throughout and
completed a quality job on programme. I would go as far to say that GAI are one Of
the best sub— contractors I have had the pleasure Of working with. I would certainly
recomrnend them for any future drylining projects/ requirements you may have.”

Wayne Fleet

Sub contractor performance review

“Having engaged G.A.Interiors on a varying level of sub contract packages over the past 6 years, I am very happy to endorse their services completely in all stages of the works from pre construction through to Pc and post completion. I have placed awards with them for dry lining packages in isolation but have also included SFS, Fire stopping and also joinery with equally impressive results. G.A.I have invested in their infrastructure enormously and are able to satisfy whatever requirements I have placed upon them in terms of ISO accreditation, construction line etc.”
