Elevating comfort with suspended floor insulation

Designed for homes with wooden floorboards above unheated spaces, it significantly increases comfort and energy efficiency by minimising heat loss through the floor.

Understanding suspended floor insulation

This type of insulation is suited for older homes that feature a crawlspace or basement underneath the living areas. It involves installing insulating materials between the floor joists that support the floorboards, preventing cold air from seeping up through the floorboards and helping maintain a consistent temperature throughout the home.

Suspended floor insulation

Floorboards

Insulating material

Typically fiberglass, which is cost-effective and easy to install, or mineral wool, known for its sound-dampening and fire-resistant properties. Eco-friendly options include sheep's wool and cellulose.

Joists

Vapour control membranes

They prevent moisture from seeping into the insulation and floor surface, helping reduce material degradation and ensuring insulation effectiveness.

Concrete slab

It's crucial to maintain a ventilation gap between the insulation and the concrete, allowing for air circulation that prevents moisture accumulation, mould growth and structural damage.

Key benefits of floor insulation

Energy efficiency

By reducing heat escaping through the floor, it can lower heating and cooling costs.

Moisture control

Proper floor insulation helps prevent moisture buildup that can lead to mould and structural damage.

Comfort

By helping maintain a stable indoor temperature, it makes living spaces more comfortable throughout the year.

Increased property value

Besides saving money on utility bills, it but can also make the property more appealing to energy-conscious buyers.
