Concrete Screed
Underfloor heating is becoming an increasingly popular feature in Maltese homes and commercial buildings — and for good reason. It offers energy-efficient comfort, a sleek finish without radiators, and a modern heating solution suited to Malta’s climate. However, for underfloor heating to perform optimally, it must be paired with the right screeding method.
In this guide, we explain everything you need to know about screed with underfloor heating in Malta, including which screeds to use, how they’re applied, and best practices for long-term results.
Why Screeding Is Essential for Underfloor Heating
Screed is the layer that covers and protects the underfloor heating pipes or cables. It helps:
- Distribute heat evenly across the floor
- Protect the system from physical damage
- Support the final flooring finish (tiles, vinyl, wood, etc.)
- Improve thermal efficiency and reduce heat loss
Without the proper screed, your heating system may become inefficient or even fail prematurely.
Types of Screed for Underfloor Heating
There are two main types of screed mainly found in Malta:
1. Traditional (Sand and Cement) Screed
- Mixed on-site and manually laid
- Usually requires a minimum depth of 65mm over pipes
- Can be reinforced with fibres or mesh for added strength
- Longer drying time (3–4 weeks)
2. Self-Levelling Screed (Liquid Screed)
- Fast-flowing and poured for quick, even coverage
- Thinner application — often around 40–50mm
- Excellent thermal conductivity
- Faster drying and walk-on times
Best Practices for Screeding Over Underfloor Heating
- Secure the heating pipes/cables properly to avoid floating during screed pour
- Use edge insulation to allow for expansion
- Test the heating system before applying screed
- Allow full curing before switching on the underfloor heating (usually 7–28 days depending on screed type)
- Gradually raise the water temperature after curing to avoid thermal shock
Benefits of Using Screed with Underfloor Heating in Malta
- Energy Efficiency: Helps maintain consistent temperatures with less energy
- Space-Saving: Eliminates need for bulky radiators
- Enhanced Comfort: Warm floors, especially appreciated in tiled spaces
- Design Freedom: Works under tiles, vinyl, wood, or polished concrete
