Underfloor Heating

screed surface finish

Underfloor heating refers to a system where heat is emitted from beneath the floor surface, creating a radiant warmth that spreads evenly throughout the room. Originating from ancient Roman hypocausts, today’s underfloor heating systems have evolved into efficient, sustainable solutions for residential and commercial buildings.

Types of Underfloor Heating Systems

Hydronic Underfloor Heating

Hydronic underfloor heating uses heated water circulating through pipes installed under the floor. This system relies on a boiler or heat pump to heat the water, which then radiates warmth upwards. It is known for its energy efficiency and ability to maintain consistent temperatures.

Electric Underfloor Heating

Electric underfloor heating involves electric cables or heating mats installed beneath the floor surface. This system is easier to install in existing buildings and allows for room-by-room temperature control, making it a versatile option for various floor coverings and building types.

Underfloor heating offers several benefits, including:

  • Enhanced Comfort: The radiant heat from underfloor systems creates a comfortable environment with no cold spots, providing gentle warmth from the ground up.
  • Energy Efficiency: By heating the floor directly, underfloor heating reduces heat loss and energy consumption compared to traditional radiators or forced-air systems.
  • Cost Savings: Although initial installation costs may be higher, underfloor heating can lead to long-term savings on energy bills due to improved efficiency and reduced heating requirements.

Cement Screed

Cement screed is a mixture of cement, sand, and water applied to concrete subfloors or bases to create a level surface suitable for the installation of floor coverings such as tiles, wood, or carpets. Its primary function is to provide a smooth and uniform foundation that enhances both structural integrity and visual appeal within buildings.

Key Characteristics of Cement Screed

Cement screed is valued for its:

  • Strength and Durability: Provides a robust base that withstands heavy foot traffic and supports various floor coverings over time.
  • Levelness and Flatness: Ensures a smooth and even surface essential for the installation of tiles, laminates, and other floor finishes.

Sand and Cement Screed
