60mm Insulation Acoustic Non combustible Thermal
60mm insulation is a practical, space-saving insulation thickness that sits below high-performance insulation build-ups. It is enough to reduce heat flow noticeably, but it still works in walls, floors, and roofs where space is limited.
It is typically specified for refurbishment projects and new builds where wall and roof thickness is restricted.
What is 60mm thick insulation?
60mm thick insulation means the material measures 60 millimetres from face to face.
Some 60mm insulation materials rely on dense, closed-cell foam, while others trap still air between fibres.
But in both types, insulation 60mm thick creates resistance to heat flow, as heat must pass through layers of trapped air, foam cells, or fibres, depending on the material used. This controlled heat movement keeps indoor temperatures stable.
What is 60mm insulation thickness used for?
Insulation 60mm is commonly used in spaces with limited room allowance. Typical uses include:
- Internal wall upgrades where the stud depth is limited
- Floors above garages or unheated spaces
- Pitched roof slopes between rafters
- Flat roofs as part warm roof or structural deck build-up
- Timber-frame walls designed around set cavity sizes
It reduces heat loss effectively for its depth and balances performance, build-up depth, and cost without pushing wall or roof thickness too far.
Types of 60mm insulation
Insulation Wholesale offers different 60mm thickness insulation materials:
EPS Insulation (60mm Expanded Polystyrene)
EPS is a lightweight board made from fused expanded beads. At 60mm, it offers moderate thermal resistance and good moisture tolerance.
- Works well on floors and some wall systems
- Does not absorb much water, but it is not fully waterproof (prolonged exposure can still affect performance)
- Lower insulation performance per millimetre compared to PIR or phenolic
- Often chosen where durability and cost matter more than slim build-ups
XPS Insulation (60mm Extruded Polystyrene)
60mm XPS provides good thermal resistance and high moisture tolerance. Ideal for floors, flat roofs, and below-ground applications.
- Very strong under compression, so it is perfect for load-bearing floors
- Water-resistant – has very low water absorption.
- Slightly higher thermal performance than EPS for the same thickness
- Straightforward to cut and fit, but edges must be sealed for full performance
Glass Mineral Wool Insulation
Glass mineral wool is flexible enough for stud walls, ceilings, and lofts.
- Noncombustible, hence excellent fire resistance
- Good acoustic performance, reducing sound transfer
- Compressible, so needs proper fitting to maintain insulation 60mm performance
- Can be friction-fitted or cut to size with a long insulation knife
Phenolic Insulation
Phenolic foam boards are dense, with fine cells that give them high thermal performance for their thickness.
- Among the highest thermal performers per millimetre
- Allows thinner constructions to meet thermal targets
- Brittle compared to PIR and needs careful cutting
- Often used where space is extremely tight
PIR (Polyisocyanurate)
PIR boards are rigid foam panels with strong thermal resistance and good handling strength.
- Commonly used in walls, roofs, and floors
- Easier to cut and fix than phenolic
- Stable performance across normal building temperatures
- A common choice when designers want reliable results without fragility
Rock Mineral Wool Insulation
Rock mineral wool insulates by trapping still air between fibres.
- Excellent fire resistance
- Strong acoustic performance
- Compressible, so a correct fitting is essential to maintain performance
VIP (Vacuum Insulation Panel) – 60mm
VIPs are panels with a rigid core under vacuum, giving very high thermal resistance in a thin layer. They are specialist systems, rarely used in standard builds.
- Extremely high thermal efficiency per mm
- Fragile – must handle carefully and avoid puncturing
- Often used in floors, walls, or service voids where space is limited
60mm Stone Wool
Stone wool is similar to mineral wool but denser. Made from volcanic rock spun into fibres. It provides excellent thermal and acoustic insulation.
- Non-combustible and highly fire-resistant
- Strong acoustic dampening
- Compressible, so fit carefully to avoid gaps
- Often installed to boost fire protection in walls, floors, and roofs
FAQ
Where to buy 60mm thick insulation?
You can buy standard 60mm insulation online directly from Insulation Wholesale. We stock a wide range of insulation materials at this thickness – from rigid boards to mineral wool slabs – so you can choose what actually suits the job. We help check suitability, availability, and lead times before you commit. We also supply UK stock, offer trade pricing, and make bulk ordering straightforward, with fast nationwide delivery.
How to cut 60mm insulation?
How you cut depends on the material:
- Foam boards: Use a fine-tooth saw or insulation knife.
- Mineral wool: Use a long insulation knife and compress the material gently while cutting to keep the edges clean. Cut a little oversized so they friction fit.
Cut on a flat surface and keep edges square. Poor cuts create gaps, and gaps reduce performance more than most people expect.
How to fix 60mm insulation?
Foam boards (PIR, phenolic, EPS, XPS):
- Place boards into studs or cavities for a snug fit
- Use adhesive or mechanical fixings suitable for the substrate
- Seal edges and joints with foil tape or sealant to prevent gaps
Mineral/glass wool/stone wool:
- Friction fit between studs, joists, or rafters
- Use insulation supports or netting in ceilings
- Avoid compressing fibres too much. Gaps and compression reduce performance
VIP panels:
- Handle carefully; place into voids without bending or puncturing
- Fix with support battens or clips as recommended by the manufacturer
General tips:
- Keep insulation tight against surfaces, with no gaps
- Stagger joints if layering
- Cut slightly oversized pieces for a friction fit when needed
