Why Underfloor Heating Insulation Matters
When you invest in underfloor heating, the goal is simple — to enjoy warm, evenly heated rooms with minimal energy waste.
However, without the correct insulation beneath the pipes or heating mats, much of that valuable heat can be lost into the sub-floor instead of rising into your living space.
By installing high-quality thermal insulation boards or panels, you:
-
Reduce heat loss and maximise system efficiency
-
Lower energy bills and improve the building’s BER rating
-
Create a faster heat-up time and more consistent room temperature
-
Protect the screed layer and ensure long-term system durability
At Irish Screed Solutions, we ensure that every insulation layer we install is level, stable, and fully compliant with Irish building regulations and manufacturer standards.
Site Preparation
The sub-floor is cleaned, levelled, and checked for moisture or irregularities to ensure a stable base.
Insulation Installation
We fit high-performance PIR or EPS insulation boards, cutting precisely around pipework, ducts, or structural columns for a seamless fit.
Edge Insulation
Expansion edging is applied around all perimeters to allow for natural movement and thermal expansion of the screed.
Vapour Barrier / Membrane
A protective membrane is laid to prevent moisture ingress and to separate the insulation from the screed layer.
Underfloor Heating Pipework
Once insulation is in place, heating pipes are clipped securely at the correct spacing to ensure even heat distribution.
Screeding & Finishing
Finally, we pour and level the screed using either liquid flow screed or traditional sand and cement, achieving a smooth, durable surface ready for final floor finishes.
Underfloor Heating Insulation
We work with trusted insulation materials from leading suppliers, selected for their strength, thermal performance, and moisture resistance.
Common choices include:
-
PIR insulation boards – excellent thermal conductivity and compressive strength
-
EPS polystyrene boards – cost-effective and ideal for domestic floors
-
High-density XPS insulation – for heavy-load areas or commercial use
Each project is assessed individually to ensure the most suitable insulation thickness and material type are used.
