Frequently Asked Questions

What is Floor Insulation?

Floor insulation involves installing materials beneath the flooring of a building to reduce heat loss and improve energy efficiency. This insulation typically consists of materials such as EPS (Expanded Polystyrene) Insulation Board, PIR Insulation Boards such as Celotex, Mineral wool batts, or multifoil rolls like Superfoil insulation - which are placed between the floor joists or beneath the floorboards. Floor insulation helps to create a thermal barrier, preventing heat from escaping through the floor and keeping the interior of the building warmer in colder months. It also contributes to soundproofing and can help to reduce energy bills by decreasing the need for heating.

What is Jablite Floor Insulation?

Jablite is a manufacturer of EPS (Expanded Polystyrene) insulation board, which is a lightweight, rigid board insulation material made from expanded polystyrene beads that can be easily cut to size and installed in various building applications, including walls, roofs, and floors - with Jabfloor being purpose made for flooring insulation. EPS insulation is manufactured by expanding polystyrene beads with steam and then moulding them into insulation boards. These boards help to reduce heat transfer and maintain consistent indoor temperatures. It is also moisture-resistant, durable, and resistant to mould and mildew growth, making it a popular choice for both residential and commercial insulation projects. In flooring, EPS insulation board is most commonly used in concrete flooring, placed on top of the initial concrete slab layer, below the final concrete screed.

Celotex Floor Insulation

As well as walls, ceilings and roofs, Celotex can be used as floor insulation in a variety of different use cases. As well as fitting between timber joists, Celotex is also suitable for use in concrete flooring above the concrete slab and below the final screed layer, as long as appropriate damp proofing is applied.

What is floor insulation?

Common materials used for floor insulation include rigid foam boards (PIR), mineral wool or EPS (Expanded Polystyrene). Floor insulation is particularly important in buildings with suspended floors or over unheated spaces such as cellars crawl spaces, or garages. Our most popular floor insulation is PIR board, which has a variety of different uses, although we also offer a more basic EPS board.
