Why you need underlay in a bedroom
Underlay plays an important role in the overall feel, performance and longevity of your carpet. Here’s why it’s a non-negotiable for your bedroom:
Comfort: in a room where cosiness is a priority, a quality underlay adds an extra layer of cushioning, making your carpet feel softer and more luxurious underfoot.
Warmth: underlay with a high tog rating is designed to retain heat, keeping your bedroom feeling toasty and your energy bills down. It works especially well for bedrooms above unheated spaces, like garages.
Noise reduction: decent underlay creates a quieter environment by reducing the transmission of sound – whether that’s dampening loud footsteps within the room or drowning out noise from other rooms or levels in the house.
Durability: underlay protects your carpet from wear and tear, extending its lifespan and keeping it in top condition for longer.
Bedroom carpet underlay: what to look for
Different underlays meet different needs. Whether you’re looking for comfort, insulation, noise reduction, durability or a combination – here’s what to consider:
- If comfort’s your priority, choose a PU foam underlay with a thickness of at least 10mm
- For colder bedrooms, look for a TOG rating of at least 3.00 to reduce heat loss
- Go for an acoustic underlay with an impact sound reduction rating of 40 dB+ for optimal soundproofing
- In bedrooms with high foot traffic, opt for a denser underlay – like sponge rubber – to give your carpet extra support
