For decades, internal walls have relied on gypsum boards, skim plaster, and film-forming paints. The Ramco–Terrix Internal Wall System replaces these outdated, multi-layered methods with a single, fully mineral solution that installs faster, performs longer, and maintains healthier indoor environments.
This complete A1-rated system unites Ramco Hilux calcium silicate boards with the Terrix® spray plaster and paint system to deliver smooth, durable, mould-resistant finishes that outlast conventional gypsum and emulsion combinations.

Built on Collaboration and Performance

Ramco + Terrix Partnership

Developed collaboratively between Ramco Industries UK and F&T Terrix, the system merges high-performance Hilux boards with next-generation mineral coatings for complete A1 compliance.

Fully Integrated Wall System

The build-up combines Hilux board, Terrix spray plaster, and silicate paint — chemically bonded for long-term integrity with no delamination.

Designed for Modern Projects

Ideal for healthcare, schools, and high-rise housing where compliance, durability, and hygiene are critical.

A1 Mineral System from Core to Finish

Hilux Calcium Silicate Board

Non-combustible, moisture-stable board delivering 60–120 minutes of fire performance and long-term structural integrity. One 12 mm board can replace two 15 mm gypsum layers.

Terrix® PL-SX-S Spray Plaster

High-performance, single-coat spray plaster with rapid drying, microfibre reinforcement, and consistent coverage.

Terrix® IP-ST-P Silicate Paint

Premium vapour-permeable, anti-mould paint offering wash resistance, zero VOCs, and Category A fire safety.

Beyond Plasterboard

Fire Safety & Strength

Certified A1 non-combustible throughout. The mineral structure resists flame, heat, and surface degradation while maintaining full integrity.

Health & Moisture Control

Fully breathable and mould-resistant — regulating humidity naturally while preventing condensation or microbial growth.

Speed & Value

One Hilux board replaces two gypsum layers, cutting material and labour costs by up to £15/m² while Terrix spray finishes reduce programme time by up to 70%.

Faster, Cleaner, Safer

Spray-Applied Technology

Mechanised spray application ensures uniform coverage, reduces labour, and increases productivity — up to 500 m² per day.

Simplified Workflow

Each mineral layer bonds chemically, removing the need for jointing, taping, or multi-coat systems.

Consistent Professional Finish

Produces a flawless, glass-flat surface resistant to impact, scratches, and routine cleaning — ideal for hospitals, schools, and public buildings.

Safe, Sustainable, Certified

Mineral, Non-Toxic, VOC-Free

Composed entirely of natural, inert minerals with no organic additives. Supports low-carbon, healthy construction.

Long-Term Performance

Designed for a 25-year guarantee and 40-year service life. Maintains surface strength and appearance under high usage and frequent cleaning.

Tested & Verified

Certified to EN 13501-1, ISO 12572, and BS 476, supported by EPDs for both Hilux and Terrix systems.

VINCI Construction – New Victoria Manchester

Project Overview

VINCI Construction selected the Terrix® spray plaster and paint system for the New Victoria development in Manchester, achieving high-speed internal wall finishing across two residential towers.

System Performance

The same spray-applied Terrix technology integrated into the Ramco–Terrix Internal Wall System was used to achieve smooth, durable, A1-rated surfaces with minimal snagging.

Results On Site

Delivered 70% faster completion, zero cracking, and a flawless finish throughout. Terrix products from this system are now preferred across multiple healthcare and housing projects.
