A Knauf Earthwool DriTherm 37 50mm cavity wall insulation slab provides excellent thermal performance for masonry cavity external walls. It is suitable for multi-storey applications up to 25m tall. Its unique ECOSE technology eliminates the need for cavity barriers, making it a superior solution for cavity wall insulation. It is also marshmallow-soft, enabling it to achieve superior environmental sustainability.
Recticel cavity boards
Recticel cavity wall insulation is available in a range of configurations, from full fill to partial fill. The company’s Eurowall PIR cavity wall insulation is an excellent choice for full cavity wall applications up to 25m high, with precision-cut tongue and groove joints and low thermal conductivity.
It is designed to fit into a minimum 10mm cavity and maintain a 10mm clear cavity. It can be installed by traditional bricklaying methods and requires minimal specialist training. The product’s unique design eliminates many installation challenges, reducing installation time and cost. Moreover, it offers quality and long-lasting performance.
Recticel cavity wall insulation is available in 25mm, 50mm, and 100mm thicknesses. It is also available in specific quantities. A typical board measures 1200x450mm and fits properly into wall tie spacings. This allows the manufacturer to achieve target ‘u’ values by using a thin product.
Recticel uses multiple layers of aluminum foil and PIR rigid foam to provide superior thermal performance. Installed properly, it should last as long as the building itself. Moreover, it is moisture resistant. Furthermore, it can be used in virtually any part of a building.
Polystyrene beads
Polystyrene beads are a relatively cheap type of cavity wall insulation. These beads are injected into the cavity of a wall using a special injection gun. The beads solidify as a mixture after they’ve been installed and are both fire and water resistant.
Polystyrene beads are easily fitted and are light in weight. They can be used in cavities up to 50mm in diameter and are ideal for both new builds and retrofitting existing buildings. The beads are also very cheap to use, costing between PS10 and PS15 per square metre. And because they are water-resistant, they don’t let moisture get inside the cavity, which makes them ideal for use in homes that are undergoing home renovation.
Cavity wall insulation is essential if you are constructing a new home or making a significant alteration to an existing one. It not only protects the building from damp, but also reduces energy bills considerably. The material should be water-resistant to reduce water damage and prevent air drafts from emerging through cracks in the walls.
Another good choice is mineral wool, a natural, eco-friendly material made from recycled materials. It is cheap, easy to install, and recyclable. The best thing about mineral wool is that it can be slid into a cavity easily, and is often pre-cut to fit the exact size of the cavity.
Polyurethane foam
Polyurethane foam cavity wall insulation is a low-cost, effective way to insulate your home. Cavity walls consist of two parallel walls with a gap in between. The outer leaf of the wall is usually made of bricks, while the inner leaf is made of concrete blocks. Cavity wall insulation is an inexpensive way to keep your home warm and comfortable while reducing energy costs. This type of insulation is applied by injecting expanding foam into the cavity using specialist equipment. The injection system is pressurised to ensure a complete fill every time. The polyurethane rigid foam system is the best choice for cavity wall insulation.
Cavity wall insulation can help prevent heat loss through the walls and prevent moisture from transferring to the inner wall. It is particularly beneficial when conventional wall ties have begun to corrode. This type of insulation also acts as a blanket against heat loss and prevents the home from becoming overly hot in the summer.
Another type of cavity wall insulation is Polystyrene beads. These insulation beads are injected into the wall cavity using a gun or hose. They are then installed using an adhesive mix. Once installed, they are water and fire-resistant.
Polyurethane beads
Polystyrene beads are the cheapest cavity wall insulation option. These beads are injected into the cavity of the wall and solidify once installed. They are also fire and water resistant. Unlike foam or mineral fibre, polystyrene beads don’t absorb moisture during installation, so there’s no need for scaffolding.
These beads can be installed in the walls of your home to improve the insulation. They are easy to install, lightweight, and can reduce the U-value of your external walls. However, it’s important to choose the right type of insulation for your home’s exterior. A 50mm cavity is the ideal length to install polystyrene, which has a low thermal conductivity (0.033 W/mK).
Cavity wall insulation can significantly reduce energy bills. Whether you’re building a new house or making an alteration, it’s essential to add this protection to your home. Not only will it help protect your home from moisture, but it will also help make your home more comfortable. A good-quality insulation also prevents air drafts from entering your home through cracks.
The polystyrene beads are injected into the cavity of the wall using a gun or hose. The holes are then sealed. The process of installing the insulation requires a trained technician. First, they will evaluate whether the space is suitable for the insulation. After that, they will clean up any holes and make sure the materials are in place correctly. Once everything is completed, the technician will check the installation and make sure everything looks right.
DriTherm cavity slabs
DriTherm cavity slabs are flexible and can be easily manipulated into the cavity space. The slabs are packaged in recyclable polythene bags. They should be stored indoors or under cover in a dry environment, and not exposed to the elements. Installed correctly, DriTherm cavity slabs help prevent the buildup of condensation and mould.
DriTherm cavity slabs are available in a variety of sizes. Whether you have a smaller or larger cavity, the DriTherm Cavity Slabs are designed to meet your needs. For maximum thermal performance, choose slabs that are at least 50mm wide and four55mm high. The DriTherm cavity slabs also meet the requirements of BCA thermal regulations. Whether you are insulating an apartment, home or commercial building, these products are a safe, environmentally-friendly solution. They provide superior insulation performance and are tested to meet Euroclass standards.
DriTherm cavity slabs are made from recycled glass mineral wool. This material is soft and cotton-like, and is part of the fibreglass insulation family. Its unique ECOSE technology gives it outstanding thermal performance. If you are considering installing this type of cavity wall insulation in your home, you should consider the benefits of Knauf’s DriTherm Cavity Slabs.
The DriTherm cavity slabs have a low thermal conductivity (U=0.037W/mK) and therefore provide excellent fire protection. This helps reduce the spread of fire, saving lives and limiting damage to the building.
Isover cavity batts
Isover’s 50mm cavity wall insulation batts are made of dense glass wool insulation and are suitable for masonry cavity walls. They are fire-safe and comply with Building Regulations. They can be installed in the middle of a wall and have a low U-value. Moreover, they are hygroscopic-free and resistant to vermin.
These insulation batts are designed for use in external masonry cavity walls and can be easily installed in a matter of minutes. They are compatible with standard wall tie spacing and are very light-weight. They are available in different widths and are easy to fit on site.

Isover Cavity Wall Insulation Batts are made of glass mineral wool slabs and offer exceptional thermal performance in masonry cavity walls. They are easy to handle and are made of a high-grade glass wool. They also reduce flanking sound transmission through the wall cavity. They are also fire-resistant and come with a Euroclass A1 fire rating. The Saint-Gobain Group produces this product.
Cavity walls are one of the biggest causes of heat loss in the UK. They are responsible for up to 35% of the total heat loss in a home. As a result, they contribute to higher energy bills. In the UK, most homes are constructed with cavity walls. These walls were originally built to prevent rainwater and moisture from entering the house. However, they can be a problem because they allow hot air to circulate between the walls. By insulating the cavity walls, you can make your house energy-efficient and save money.
