200mm Insulation Non combustible
200mm insulation is a deep thermal layer specified to control heat loss across large areas. Insulation becomes a core part of the building envelope at this depth. This thickness is typically suitable where high levels of comfort and energy efficiency are required.
What is 200mm thick insulation?
200mm thick insulation means the installed material measures 200mm after installation, assuming proper fit with no significant gaps. That depth increases the thermal resistance by extending the heat flow path.
With insulation 200mm thick, performance comes from:
- Large volumes of air trapped within the insulation structure.
- The increased layer depth significantly slows heat transfer.
While the type of material affects performance, thickness remains the primary factor limiting heat transfer.
What is 200mm insulation used for?
200mm insulation thickness is used where very low levels of heat loss are required, such as:
- Loft floors in modern homes
- Warm roofs with strict energy targets
- Floors above unheated spaces
- External walls designed to achieve high thermal performance
This depth is common where buildings aim to exceed minimum standards.
How many types of 200mm insulation are there?
There are several main types of thick insulation 200mm:
Mineral wool insulation
Made from spun stone fibres. The material traps air between dense strands, slowing heat movement. It also improves sound control and resists fire. Often used in lofts, timber frames, and floors where sufficient space allows full-depth installation.
Glass wool insulation
Lighter and more flexible than mineral wool. It relies on its springy structure to fill voids and prevent air movement. Easy to fit in lofts and joists, but must not be compressed as compression significantly reduces thermal performance.
Rigid PIR insulation boards
These are foam boards with foil faces. They achieve high thermal resistance even with reduced profiles, so 200mm thickness insulation can be formed by layering boards. Used where precise build-ups are needed.
Phenolic insulation boards
Similar to PIR but with even higher thermal resistance. Preferred where detailing tolerances are tight. Often layered to reach full depth.
Each type can provide 200 thick insulation, but the installation method matters as much as the material. Gaps, compression, or poor fitting can compromise performance.
Benefits of thick 200mm insulation
200mm thick insulation offers:
- Strong heat retention. The depth greatly reduces heat escape, especially through roofs and floors.
- Stable indoor temperatures. Rooms stay warmer for longer, with fewer cold surfaces.
- Lower energy demand. Heating systems do not have to be on all the time, reducing running costs over time.
- Improved comfort. Cold draughts and temperature swings are reduced.
- Future-proofing. This thickness aligns well with current and future energy efficiency standards.

FAQ
Where to buy 200mm thick insulation?
You can buy 200mm thick insulation online from Insulation Wholesale. Our UK stock includes multiple insulation types, so you are not limited to one specific material. Our team can help match insulation to structure, space, and regulations. We offer low wholesale pricing, trade support, and fast, dependable delivery to make planning easier.
How to cut 200mm insulation?
Cutting method depends on the material:
- Mineral or glass wool: Cut using a long insulation knife and a straight edge.
- Rigid boards: Score each board deeply, then snap along the scored line.
Cut soft insulation slightly oversized so it fits snugly without gaps.
How good is 200mm insulation?
Very good when fitted correctly. At a 200mm thickness insulation, heat loss through roofs and floors is significantly reduced. Indoor comfort improves, and energy use drops noticeably. The key factor is proper installation, since depth only works if the insulation is continuous and uncompressed.
