Product Overview

Knauf Frametherm Roll 40 with a 90mm thickness providing 14.25m² coverage per roll. This general-purpose glass mineral wool insulation offers cost-effective thermal performance with a conductivity of 0.040 W/mK. 

Produced using ECOSE® Technology, it combines environmental responsibility with reliable insulation properties. 

The 90mm thickness makes it suitable for standard timber or metal frame walls, partitions, and service cavities where moderate thermal performance is required.

Features & Benefits

  • Thermal performance: 0.040 W/mK conductivity for practical insulation efficiency.
  • Non-combustible: Euroclass A1 fire rating ensures compliance with safety standards.
  • Sound absorption: Improves acoustic separation between internal spaces.
  • Sustainable production: ECOSE® Technology reduces environmental impact and emissions.
  • Quick installation: Roll format enables simple friction-fit placement between studs.
  • Thickness and coverage: 90mm roll providing 14.25m² coverage for standard frame wall applications.


Applications

  • Timber and metal frame walls: Used in internal or external cavity systems.
  • Partitions: Reduces heat loss and sound transmission between rooms.
  • Service cavities: Provides insulation where additional thermal layers are installed.
  • Loft and attic areas: Suitable for intermediate insulation in non-habitable zones.


Installation Guidance

  • Cutting: Trim cleanly using a sharp insulation knife for precise fit between studs.
  • Fitting: Place friction-tight without gaps; do not compress to ensure full performance.
  • Protection: Handle with gloves and mask in ventilated areas.
  • Storage: Keep dry and protected from weather prior to installation.


Compliance & Performance

  • Thermal conductivity: 0.040 W/mK.
  • Fire classification: Euroclass A1 non-combustible to EN 13501-1.
  • Acoustic performance: Tested to meet relevant sound insulation standards in framed systems.
  • Environmental compliance: Manufactured with up to 80% recycled glass and formaldehyde-free binder.
  • Important note: Maintain product thickness and continuity to achieve stated thermal values.

How delivery works

We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.

Delivery areas

Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.

If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.

What to expect on delivery day

  • Deliveries are typically kerbside.
  • Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
  • Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.

Why delivery can cost more than typical parcel delivery

Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.

Returns

Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.
