Insulation Boards

Electric Insulation Boards

Electric insulation boards are designed to be laid directly beneath your electric underfloor heating system, helping to reduce heat loss and keep you warm throughout the winter months. These electric insulation boards are made from high-grade polystyrene and fibreglass mesh to provide a durable and long-lasting product suitable for any underfloor heating project or renovation.

Water Insulation Boards

Water Insulation Boards

Water insulation boards are installed directly below your water underfloor heating system, working to save both energy and money. These boards are perfectly safe for use with hot water systems and provide outstanding thermal performance when used beneath a wet underfloor heating system. Designed with high-grade polystyrene, these boards offer enhanced resistance to fire, rot and general corrosion as well as providing excellent acoustic insulation properties which can help reduce noise level in the home.

Do I need to install insulation boards underneath underfloor heating?

It is highly recommended to install insulation boards underneath all underfloor heating systems. The insulation will enable the underfloor heating to concentrate all of its efforts on heating up the tile/floor covering above as opposed to losing heat into the ground below. The thicker the insulation the more efficient and economical the system will become.

Are insulation boards any good?

Insulation boards can be highly beneficial for various applications and offer several advantages:

  1. Thermal Insulation: Insulation boards provide effective thermal insulation, helping to reduce heat transfer between different areas. They can help prevent heat loss from the heated space, keep cold air out, and maintain a comfortable indoor temperature. This can lead to energy savings and improved heating efficiency.
  2. Moisture Resistance: Insulation boards are often moisture-resistant or have moisture-repellent properties. This makes them suitable for areas where moisture exposure is a concern, such as basements, bathrooms, or areas prone to condensation. Moisture resistance helps to prevent the growth of mould and mildew and enhances the longevity of the insulation.
  3. Sound Insulation: In addition to thermal insulation, certain types of insulation boards also offer sound insulation properties. They can help reduce noise transmission between rooms or from outside sources, providing a quieter and more peaceful indoor environment.
  4. Easy Installation: Insulation boards are typically lightweight and easy to handle, making them convenient to install. They can be cut to size, fitted into cavities, or attached to walls, floors, or ceilings using appropriate adhesives or fixings. Their ease of installation can save time and effort during construction or renovation projects.
  5. Versatility: Insulation boards are available in different materials, thicknesses, and sizes, offering versatility for various applications. They can be used in walls, floors, roofs, and other areas where thermal or acoustic insulation is needed. Some insulation boards also have additional properties, such as fire resistance or vapor barrier capabilities.

It's important to choose insulation boards that are appropriate for your specific needs and meet the required insulation standards for your region. Consider factors such as R-value (thermal resistance), moisture resistance, fire rating, and any specific requirements for your building project.

What is insulation board used for?

Insulation boards are used for various applications in both residential and commercial construction, primarily used to provide thermal insulation, helping to reduce heat transfer and maintain comfortable indoor temperatures. They are used in walls, roofs, and floors to prevent heat loss in cold climates and heat gain in hot climates.
