Draughts and cold spots can quickly make a home uncomfortable, especially in winter. Many homeowners experience uneven heating and higher energy bills due to gaps in walls, floors and lofts. These issues increase heat loss and raise energy consumption.
Modern solutions like spray foam insulation in Hampshire provide an effective way to stop unwanted cold air entering your home. Unlike traditional insulation, spray foam expands to seal every gap and crevice, creating a continuous thermal barrier. This keeps rooms warmer, reduces draughts and maintains consistent temperatures throughout the property.
What Causes Cold Spots and Draughts?
Cold spots usually occur due to cracks, gaps or poorly insulated areas in walls, floors and around windows. Draughts let cold air in and force warm air out, making your heating system work harder. Temporary solutions like draft excluders only mask the problem, whereas spray foam provides a long-term fix.
How Spray Foam Insulation Works
Spray foam expands to fill cavities and seal areas that traditional insulation often misses. It acts as both an insulator and an air barrier, significantly reducing heat loss.
