Carpet underlay designed to add cushioning and extend carpet life, Carpenter Midas PU Carpet Underlay. Rooms feel warmer and quieter, with a noticeably cushioned step. Is the added thickness and density the right choice for longer-lasting flooring?

⚡ At a Glance
  • Wearing Comfort: 12mm thickness and firm PU density create a supportive, plush feel underfoot
  • Best for: Homeowners fitting new carpets who want improved comfort and longer carpet life
  • Not ideal for: Installations requiring minimal floor build-up under door clearances

12mm PU foam at 90kg per m3 gives a firm supportive layer that cushions footfall and protects carpet backing. 1.37m roll width and large length options reduce joins for faster fitting and neater results.


Plush, supportive feel - thanks to 12mm PU thickness

12mm polyurethane foam increases the depth between carpet and subfloor, absorbing footfall and smoothing surface irregularities. Measured tog of 2.71 indicates meaningful thermal resistance alongside cushioning.

Extra depth improves underfoot comfort and makes rooms feel warmer. Carpets sit more evenly, reducing impressions and enhancing everyday comfort.

Improved longevity for carpets - thanks to 90kg per m3 density

Higher density PU at 90kg per m3 resists compression and distributes loads across a broader area, limiting wear to carpet fibres and backing. Grade A construction signals consistent material quality across rolls.

Denser underlay slows flattening and pile damage, helping carpets retain appearance for longer. Heavier traffic areas benefit from reduced matting and better long-term support.

Quicker, neater installation - thanks to 1.37m width and large roll lengths

Rolls arrive 1.37m wide with selectable area coverage, including 10m² options, so fittings often require fewer joins. Samples available let fitters check fit and pile compatibility before cutting full-length pieces.

Wider rolls cut down on seams and installation time, producing a tidier finish with fewer joins. Fewer joins reduce opportunities for seam movement and simplify fitting in larger rooms.

  2. Samples available - Check compatibility and feel before committing to full roll lengths
