Underfloor Insulation

Underfloor insulation is one of the cheapest and easiest ways to insulate your home. 

Correctly installed underfloor insulation can also reduce rising damp, as the underfloor insulation helps prevent moisture from penetrating into the house from a damp floor – creating a warmer, drier, healthier and more energy efficient home.

Underfloor insulation also has the added benefit of reducing sound on wooden floors and helps eliminate draughts with exposed floorboards.

Your One Stop Shop for Underfloor Insulation

There are two main options for underfloor insulation, and GreenSide Energy Solutions will help you choose the right option for your home:


Bulk insulation

Typically made from polyester, natural wool, rock wool, or expandable polystyrene material, this insulation traps heat inside the house during the winter and blocks heat from entering during the summer. 


Reflective foil insulation

Using either single or doubled-sided fall laminates, bubble wrap, or foam foil-faced wrap, the reflective foil insulation can lower radiant heat gain.
