Underfloor Heating Accessories

Underfloor heating accessories are essential to the performance and reliability of any installation. For instance, installing insulation boards over the subfloor can improve system efficiency by up to 50%, ensuring heat is directed upward where it’s needed most. It’s also worth fitting a spare floor temperature sensor at the outset of every project—this provides an instant backup if a sensor ever fails, saving time, reducing costs, and avoiding unnecessary disruption later on.

Key takeaways:

  • Boost efficiency

  • Reduce impact sound

  • Control easily

  • Tank with ease

  • Strengthen floors

  • Mitigate risk

“Fantastic company. Terrazzo sent samples free of charge. We had limited depth and they offered a solution. I would use them again as everyone I spoke to was friendly, helpful and a delight to deal with.”

“Great selection and we received great advice on which tiles would work best in our rooms. We also had a pattern in mind but Evelina helpfully advised against it because of the space - she suggested something else instead that would provide a similar effect but would work well in our space, and we’re so pleased with the result! Highly recommended!”
