There are many types of insulation for different types of projects. At Bells, we will always start by looking at your plans or listening to your needs and provide our recommendations on the best type of insulation for your project. Whether this is bulk thermal insulation or reflective faced rigid or semi-rigid boards and blankets, acoustic insulation or additional protection to your building against natural forces like fire or water.

Below we have categorised the most common types of insulation that we come across on a daily basis, categorised by the structural elements of a building. Of course, if your project requires an insulation solution that is a little less common, we are also happy to provide customised options, materials and constructions. We always strive to find the best and most efficient solution to meet your specific project needs.



Sarking and Wall wraps are a membrane wrapped around the frame of a structure and can offer benefits such as weather protection and even some reflective thermal insulation benefit. Care needs to be taken to match the right product with the application

Insulation for external walls may involve a sarking or wall wrap for weather protection and support for thermal insulation between the exterior skin and the interior wall lining. Depending on the project requirements, we use batts, foil faced polystyrene solutions or other materials to provide the optimal thermal solution.When applying insulation, we always pay specific attention to parts of the construction that could lead to thermal leaks, where big heat gains and losses can occur, like so-called bulkhead walls & earth walls in split level homes. Bulkhead walls exist where there is a variation in ceiling height or in split level structures where part of a wall backs on to the attic of a lower level.

Inside temperatures in a building are usually averaged through the opening of doors and general traffic, internal wall insulation can help maintain a consistent temperature in specific rooms or help maximise the thermal efficiency of a building.The most common form of internal wall insulation is acoustic insulation. We offer several high-end products to improve acoustic performance within a building and control noise and have extensive experience with a large variety of internal wall constructions.

At Bells, we pay special attention to the insulation of the roof of any construction. Not only can the roof be one of the biggest thermal leaks, it also requires a specific style of construction and often the installation of ventilators to avoid condensation. Roof blankets not only provide a good thermal solution, it also provides acoustic insulation against rain, especially on a metal roof.To optimise the effectiveness of roof insulation, we always recommend to complement the roofing blanket with insulation on a ceiling level.

As with internal walls, thermal insulation is usually only applied to maintain a consistent temperature in a specific room or to maximise efficiencies. Most of our attention with floors goes to providing good acoustic insulation. Not only do we provide solutions to limit air-borne noise, but we also pay attention to impact noise. We can also provide advise in the design phase as much can be gained from a good floor construction.In addition to floor insulation, a solid ceiling insulation can further minimise noise between levels and help maintain a consistent room temperature. We provide optimal insulation solutions and have extensive experience in a large variety of ceiling systems. From suspended ceilings – that can be notorious thermal leaks in commercial buildings and office spaces – to pitched roof ceilings, cathedral ceilings or raked ceilings. Whatever ceiling you use in your project, we have a solution to make sure it’s perfectly insulated.

Depending on the construction and finishing, the underfloor can lead to a considerable gain or loss of heat and a lot of draughts in older structures. By installing insulation under the floor you ensure the floor surface maintains the inside house temperature as against the extremes of the outside near ground climate plus we stop any air movement. Underslab Insulation to Commercial Buildings over Car Parks is an ever increasing area of our work to meet Section J Requirements.

Rockwool Fireseal is a form of protective insulation for your building where  fire suppression is required. Different Specifications and Regulations apply with Bush Fire Protection and also Spread of Fire in Multi-tenenanted constructions.
