Flat roof insulation service UK

Does your flat roof need a heat-saving makeover? Look no further than Oakley Improvements, the UK’s premier provider of comprehensive flat roof insulation services. We deliver exceptional solutions to keep your home warm, cozy, and energy-efficient, while reducing your carbon footprint

Warm Roof Insulation

  • The insulation is placed on top of the roof deck.
  • Can help to reduce heat loss in the winter and heat gain in the summer.
  • Can improve the lifespan of the roof.
  • Can add value to the property.

Cold Roof Insulation

  • The insulation is placed between the roof joists.
  • Does not provide as good thermal performance as warm roof insulation.
  • Is easier to install.
  • Can be used on existing roofs

Application Overview

Mechanically fixed single ply roofing systems are held in place by mechanical fasteners that secure the membrane over the insulation and VCL (vapor control layer). This type of roofing system is ideal for applications where speed of installation is critical, such as schools.


Our insulation solutions for flat roofs provide both excellent fire and acoustic performance, in addition to high levels of thermal performance. We offer a wide range of insulation products to meet the specific needs of your project.

Why Mineral Wool?

Mineral wool is a versatile insulation material that offers excellent thermal, fire safety, and acoustic performance. It is made from natural materials, such as rock or slag, and is non-combustible. Mineral wool is also moisture-resistant and can be used in a variety of applications, including walls, ceilings, floors, and roofs.

Here are some of the benefits of using mineral wool insulation:

  • High thermal performance: Mineral wool has a high R-value, which means it is very good at preventing heat loss. This can help to reduce energy bills and improve comfort.
  • Fire safety: Mineral wool is non-combustible and can help to protect your home from fire. It is also used in fireproofing applications, such as firewalls and fire doors.
  • Acoustic performance: Mineral wool is an excellent sound insulator. It can help to reduce noise levels in your home and create a more peaceful environment.
  • Easy to install: Mineral wool is easy to install and can be cut to fit any size space. It is also available in a variety of forms, such as batts, rolls, and loose-fill.
  • Environmentally friendly: Mineral wool is made from natural materials and is recyclable. It is a sustainable choice for insulation.

Application Overview

Insulation can be friction-fitted between rafters. For further enhanced thermal performance, a layer of non-combustible Rocksilk® RS45 can be installed underneath the rafters.

Rooms-in-roof are often used as bedrooms, where acoustic performance and sound reduction of external noise are essential considerations in addition to thermal performance. Our insulation solutions for warm roofs provide both thermal efficiency and acoustic performance.
