Underlay Supply and Fitting in Peterborough — The Foundation of a Great Carpet
Cambridgeshire Carpets supplies and fits carpet underlay across Peterborough and the surrounding area — including Orton, Werrington, Hampton, Bretton, Longthorpe, Stanground, Whittlesey, Yaxley, Stamford, Huntingdon, and Ely. Underlay is one of the most important investments you can make when fitting new carpet: the right underlay improves comfort underfoot, reduces noise transmission between floors, extends carpet life significantly, and can improve your home's energy efficiency.
We include underlay as standard in all our carpet fitting quotes, and we carry a range of underlay types to suit every carpet weight, room use, and budget. If you have existing underlay in good condition, we'll assess it honestly — we'll only recommend replacement if it's genuinely needed.
Types of Underlay We Supply and Fit in Peterborough
Not all underlay is equal, and the right choice depends on the carpet you're fitting, the room's use, and the subfloor type. Here's what we offer:
- PU (polyurethane) foam underlay: The most common type for domestic carpet fitting. Available in weights from 100g/m² (entry level) to 170g/m² and above (premium). Higher-weight PU foam gives more cushion, better sound absorption, and longer life. Suitable for living rooms, bedrooms, and most carpeted areas.
- Rubber crumb underlay: Denser and firmer than PU foam — excellent for loop pile and Berber carpets, which can buckle over soft underlay. Also better for high-traffic areas like hallways and stairs. We use Cloud 9 Cumulus, Duralay Heatstore, and Tredaire Softstep.
- Felt underlay: Traditional wool-felt or synthetic-felt underlay — excellent thermal properties, natural material, and very effective on timber subfloors where sound transmission is a concern. Preferred for period properties in PE1 and PE2.
- Thermal underlay: Specifically engineered to retain heat — reduces heat loss through the floor by up to 30% compared to standard underlay. Ideal for rooms with poorly insulated concrete subfloors or properties without underfloor insulation. Duralay Heatstore is our most popular choice for this application.
- Stair underlay: Firmer, narrower cut specifically for stair treads — prevents carpet from wearing at the nose of each step. We use rubber crumb stair underlay as standard on all stair carpet fitting.
Tog Rating and Why It Matters in Peterborough Homes
Underlay tog rating measures thermal resistance — higher is warmer. In Peterborough, where homes span everything from Victorian terraces in PE1 to modern new builds in Hampton and Cardea, the right tog rating makes a measurable difference:
- 1.0–1.5 tog: Standard — suitable for centrally heated homes with well-insulated floors.
- 2.0–2.5 tog: Mid-range — good for older properties with solid concrete ground floors.
- 3.0+ tog: High thermal performance — ideal for homes where the floor is cold to the touch, rooms above garages, or ground-floor rooms in pre-1950 properties.
We'll advise on the right tog rating for your specific property at your free home visit.
Underlay for Underfloor Heating — What to Specify in Peterborough New Builds
Underfloor heating (UFH) systems are increasingly common in Peterborough new builds — particularly in Hampton Vale, Hampton Hargate, Cardea, and Stanground South. If you have UFH, you must use low-tog underlay designed for the purpose — otherwise the underlay insulates against the heat you're paying to generate. Key guidance:
- Maximum combined tog rating (carpet + underlay) for UFH systems is typically 2.5 tog
- The underlay alone should be no more than 1.5 tog
- Use PU foam underlay specifically rated for UFH — we recommend Duralay Durafit UFH or equivalent
- Always check your UFH manufacturer's warranty conditions before specifying underlay
Underlay for Timber Subfloors — Getting It Right in Older Peterborough Properties
Many Peterborough properties — particularly Victorian and Edwardian terraces in PE1 and PE2, and 1930s–1960s semis in PE3 and PE4 — have suspended timber subfloors. The right underlay choice here is critical:
- Felt or rubber underlay is preferred — it bridges minor gaps between boards and improves sound absorption
- PU foam can sink into gaps over time if boards are widely spaced — use only on sound, close-boarded floors
- A hardboard overlay is recommended where boards are uneven or gappy — adds cost but protects both carpet and underlay
