Ever wondered why your carpets feel so plush and cozy underfoot? It’s not just the carpet itself – it’s the secret weapon beneath: carpet underlay. Think of it as the unsung hero of your flooring. It’s a layer of material placed between your carpet and the subfloor, providing a cushion of comfort, insulation, and noise reduction. Not only does it make your carpets feel amazing, but it also helps to extend their lifespan by absorbing the pressure of foot traffic and reducing wear and tear.
What is the Best Underlay for Carpet?
When it comes to choosing the right underlay for your carpet, there are several options available, each with its own unique benefits. Some of the most common types of underlay include:
- PU (Polyurethane) foam: This is a popular choice due to its excellent combination of comfort, insulation, and noise reduction. PU foam is also a recycled material, making it an environmentally friendly option.
- Sponge rubber: Known for its durability and resilience, sponge rubber underlay provides good support and cushioning.
- Crumb rubber: Made from recycled rubber, crumb rubber underlay is a cost-effective option that offers decent insulation and noise reduction properties.
While all of these options have their merits, PU foam is generally considered the best choice for most applications. It provides excellent comfort underfoot, a good tog insulation rating, and excellent noise reduction properties, helping to extend the life of your carpet.
How Long Does Carpet Underlay Last?
In theory, carpet underlay is designed to last the lifespan of the carpet it supports. However, several factors can influence its longevity:
- Quality and Thickness: Higher quality and thicker underlay tends to be more durable and long-lasting.
- Humidity: Excessive moisture can cause certain types of underlay, such as PU foam, to degrade more quickly. A humid environment can also lead to the growth of mould and mildew, affecting the quality of your floor.
- Spillages: Spillages that penetrate the carpet can reach the underlay and cause it to break down or develop unpleasant odours.
- Installation: A poorly fitted underlay can lead to gaps or overlaps, which can accelerate wear and tear.
By considering these factors and choosing a high-quality underlay, you can help ensure that it lasts for the entire lifespan of your carpet.
What Thickness of Underlay for Carpet is Best?
We offer a high-quality 8mm underlay as standard with all our fitted carpets We've found that an 8mm underlay provides a great balance of comfort and performance for most carpet installations. While you can opt for thicker options, remember that going too thick can make it harder to secure the carpet with grippers.
t's not just about thickness; the density is also important. A super-thick underlay with low density might not offer the best support. In general, thicker underlays tend to be higher quality, but they can also be more expensive. For luxury carpets, 11mm might be a good choice, while 10mm or 8mm are more common for everyday use.
A thicker underlay can feel warmer underfoot and potentially help you save on heating bills. So, when choosing the right thickness, consider your budget, the type of carpet, and your personal preferences.
Can I Use Old Carpet as Underlay?
Unfortunately, we cannot install carpets onto existing underlay or carpet. Using old carpet as underlay can create health hazards and shorten the lifespan of your new carpet. For a clean and long-lasting installation, it's essential to start with a fresh floor and underlay.
Do I Need to Replace Carpet Underlay?
Underlay typically only needs to be replaced when you install a new carpet. However, as we've discussed, if your underlay becomes compromised due to factors such as soiling, mould, moisture, stains, bugs, or inadequate support, it may need to be replaced sooner.
What happens if you don't use underlay for carpet?
Not using underlay for your carpet can have several negative consequences:
- Reduced comfort: Underlay provides a cushioning layer, making your carpets feel softer and more comfortable underfoot. Without it, your carpets may feel hard and uninviting.
- Increased noise: Underlay acts as a sound barrier, helping to reduce noise transmission between floors. Without it, footsteps and other sounds may be more noticeable.
- Shorter carpet lifespan: Underlay helps to distribute foot traffic and protect your carpet from wear and tear. Without it, your carpet may wear out more quickly.
- Reduced insulation: Underlay can help to improve your home's insulation, keeping it warmer in the winter and cooler in the summer. Without it, your energy bills may be higher.
- Uneven surfaces: Underlay can help to smooth out minor imperfections in your subfloor, creating a more even surface for your carpet. Without it, your carpet may look uneven or develop wrinkles.
By using underlay, you can help to ensure that your carpets are comfortable, durable, and energy-efficient.
