Underfloor insulation is a cost effective way to prevent cold air creeping under floorboards. It also reduces draughts and helps to keep your home warmer in winter and cooler in summer.
This type of insulation is typically used in older homes with elevated floors fitted across joists and a crawl space underneath. It is important to note that this type of insulation requires a professional installer as the process involves removing your floorboards and accessing the underside of the floor. The use of a protective covering over the top of the insulation will be required, to ensure that moisture and dirt do not damage it or degrade its properties.
The correct method of installing underfloor insulation can significantly reduce your energy bills and help to improve the overall comfort of your home. Underfloor insulation can be made of fibreglass, mineral wool or polyester. Sheep’s wool underfloor insulation is a natural and eco friendly product that offers excellent R-Value (representing resistance to heat flow) and has good moisture retention. It is also breathable, helping to regulate humidity levels in the suspended floor space. It is resistant to pests, mildew and rodents, as well as fire resistant.
It’s worth noting that underfloor insulation alone does not fully insulate your home, you will need to seal any draughts in the walls and ceilings. This will make your home even more energy efficient and comfortable all year round. It will also encourage you to rely on artificial heating and cooling less, which cuts down your electricity usage and lowers your energy bills.
