Welcome to the Insulation4less category dedicated to 90mm insulation solutions! Explore a variety of insulation products tailored to meet your specific building and energy efficiency requirements.

90mm insulation typically finds its place in various applications within the building industry, offering enhanced thermal performance, making it a go-to thickness for several professionals. Here’s an overview of some grouped products:

General-Purpose Insulation Boards

Celotex GA4000 and IKO Enertherm ALU are notable mentions in this category, designed to provide versatile solutions. These general-purpose insulation boards cater to numerous applications including roof, floor, and wall insulation, ensuring an overall thermally efficient envelope.

Kingspan

Kingspan, a renowned name in the insulation world, brings forth several products in the 90mm category:

  • Kingspan Thermafloor TF70 specifically caters to floor insulation needs.
  • Kingspan Thermaroof TR26 & TR27 are tailored for flat roof insulation applications, ensuring thermal consistency.
  • Kingspan Kooltherm K103 and K107 are crafted for floor and pitched roof insulation respectively, ensuring the efficiency and integrity of thermal performance in these spaces.

     

Focus on Specific Use Cases

Some products cater to very specific use cases, offering specialised solutions:

  • Thermaclass Cavity Wall 21 Celotex is formulated for cavity wall applications, ensuring the minimization of thermal bridges.
  • Rockwool Rainscreen Duo Slab is designed to function effectively in rainscreen façade applications, providing robust fire resistance and thermal insulation.

     

Enhanced EPS Insulation

With products like Enhanced EPS, the aim is to provide a lightweight yet effective insulation solution. Available in varied sizes, EPS insulation is favoured for its ease of handling and installation, particularly underfloor systems.

Versatility with Actis and Jablite

Actis Hybris and Jablite offerings in this insulation thickness are known for their multi-reflective insulation characteristics, providing a blend of thermal, acoustic insulation with the added benefit of no risk of moisture retention.

Flexible and Resilient Solutions

Knauf Rocksilk Flexible Slab leans into providing a resilient and flexible insulating solution. Ideal for applications demanding a bendable product which doesn’t compromise on thermal performance.

Selecting the Right 90mm Insulation: A Guideline

Choosing the right insulation starts with identifying the application:

  • For Floor Insulation: Consider products like Kingspan Thermafloor or Kooltherm K103 which cater specifically to insulating floors.
  • Roof Insulation: Depending on the roof type (pitched or flat), select from Kingspan’s varied offerings like Thermaroof or Kooltherm K107.
  • Wall and Cavity Wall Insulation: General-purpose boards like Celotex GA4000 or specialised options like Thermaclass Cavity Wall may be explored.
