Basement Wall Insulation

An incredible 28 percent of people living in cold homes are at risk of developing multiple health problems – caused by lack of warmth.

Incorrectly insulated basement accommodation can be a significant contributor to this – while correct installation can improve warmth and comfort in the cellar space, and rooms above.

ROCKWOOL basement wall insulation substantially increases comfort and liveability, thanks to the 7 Strengths of Stone³.

Advantages for basements and cellars include:

• Fire protection – more basement flats are being created, presenting new fire risks. ROCKWOOL insulation can withstand temperatures above 1000°C⁴.
• Temperature maintenance – heat loss through walls is reduced, levelling temperatures and creating a comfortable environment⁵.
• Robust – ROCKWOOL insulation leaves no gaps in-between layers and doesn’t sag over time, ensuring lifetime performance⁶.
• Flexible – our insulation is simple to install in-between wall studs and is adaptable to different below ground wall surfaces⁷.
• Water repellent and air permeable – stone wool insulation repels water where required but is also breathable, reducing the risk of damp occurring^8.

ROCKWOOL products are designed for easy installation in-between wall studs, or as a system solution with insulation and finish in one. 

Key tips:

• When installing a vapour barrier, make sure all joints overlap and are taped tight, and punctures are repaired. This ensures proper performance over time. 
• If you need to cut down insulation to fit in-between studs, leave additional width when cutting to ensure it fits tightly against the wall.
• When applying insulation with a pre-fixed finish against the wall, use a regular glue that offers long-lasting adhesion.

Sustainability and energy efficiency

ROCKWOOL is created using one of the world’s most abundant natural resources: stone.

We take stone, the most abundant natural resource on Earth, and upcycled secondary materials that would otherwise end up as waste and turn them into long lasting stone wool insulation products. These products are themselves recyclable and can be recycled again and again without any deterioration in quality.

The temperature regulating properties of stone wool also help contribute to lower energy usage and by extension the lowering of Europe’s greenhouse gas emissions - the UK’s housing stock is responsible for approximately 20% of the country’s total greenhouse gas emissions.
