External Walls

Application Overview

External Wall Insulation (EWI) is a technique involving the addition of an insulating layer to a building’s exterior surface, which can be applied to existing or newly constructed structures. Typically, this insulating layer is then finished with a render coat, providing both thermal benefits and an improved external appearance.


Our Rock Mineral Wool insulation is an ideal choice for external wall insulation. It offers not only enhanced thermal and acoustic performance but also boasts a non-combustible nature, enhancing safety. By opting for our Rock Mineral Wool insulation, you can achieve effective external wall insulation with notable thermal and acoustic advantages while prioritizing fire safety.

Why Mineral Wool?

Mineral wool is a versatile insulation material that offers excellent thermal, fire safety, and acoustic performance. It is made from natural materials, such as rock or slag, and is non-combustible. Mineral wool is also moisture-resistant and can be used in a variety of applications, including walls, ceilings, floors, and roofs.

Here are some of the benefits of using mineral wool insulation:

  • High thermal performance: Mineral wool has a high R-value, which means it is very good at preventing heat loss. This can help to reduce energy bills and improve comfort.
  • Fire safety: Mineral wool is non-combustible and can help to protect your home from fire. It is also used in fireproofing applications, such as firewalls and fire doors.
  • Acoustic performance: Mineral wool is an excellent sound insulator. It can help to reduce noise levels in your home and create a more peaceful environment.
  • Easy to install: Mineral wool is easy to install and can be cut to fit any size space. It is also available in a variety of forms, such as batts, rolls, and loose-fill.
  • Environmentally friendly: Mineral wool is made from natural materials and is recyclable. It is a sustainable choice for insulation.

Masonry Cavity Wall

Application Overview

Integrated into the construction process, full-fill built-in insulation solutions are seamlessly incorporated as walls are erected. These solutions entail the insertion of insulation slabs between the interior and exterior layers of the wall, employing a friction-fit technique that positions the slabs securely between wall ties.

The primary and overarching consideration of this method is the optimization of thermal performance. This entails a crucial requirement for the insulation material to establish close and uninterrupted contact with both the inner and outer walls. The objective here is to effectively eliminate any potential air movement that could lead to subsequent heat loss.

Blown-In

Application Overview

In the context of new construction, full-fill blown-in insulation solutions are introduced through pre-drilled installation holes by approved technicians after wall completion and when the building is sealed against water intrusion. The primary objective here is to ensure optimal thermal efficiency, necessitating intimate contact of the insulation with both sides of the wall to eliminate air movement and consequent heat loss.

Our blown insulation systems, non-combustible in nature, excel in fully occupying the cavity. Endorsed by BBA certification for deployment across all exposure zones, these systems embody both enhanced thermal performance and adherence to stringent safety standards.

Masonry Cream

Application Overview

Application of masonry cream onto a surface serves to insulate mineral-based construction materials by diminishing water absorption. Through chemical bonding, the masonry cream permeates up to 17mm into the surface, establishing an imperceptible insulating barrier.
