Product description

Knauf Insulation Unifit 035 – high-quality mineral wool for insulating pitched roofs

Knauf Insulation Unifit 035 is a mineral wool mat designed for projects where high insulation performance is essential whilst maintaining an optimal material thickness. The thermal conductivity coefficient λD = 0.035 W/mK enables excellent thermal performance, making the product ideal for both new-build projects and the thermal refurbishment of existing buildings. The use of ECOSE® technology and features designed to facilitate installation make Unifit 035 a popular choice amongst contractors and designers.

State-of-the-art technology and easy installation

Unifit 035 is manufactured using ECOSE® technology, which utilises natural, rapidly renewable raw materials. The production process does not involve the use of formaldehyde, phenols, acrylics or artificial colourants, and energy consumption is up to 70% lower than with traditional mineral wool production technologies.

The design of the mat itself also affects working comfort. Its increased rigidity ensures that the material remains securely in place between the rafters, without the need for additional fixings. The ribbed structure enhances the mat’s integrity and makes it easier to unroll, whilst the printed cutting lines allow you to quickly and precisely cut the insulation to the required size.

Applications of Knauf Insulation Unifit 035

Knauf Insulation Unifit 035 has been developed primarily for the insulation of pitched roofs, where high thermal efficiency and easy installation are required. It is ideal for installation both between and beneath rafters, creating single- or multi-layer insulation systems. This solution is particularly recommended when renovating older roofs, where the height of the rafters limits the possible thickness of the insulation.

The material is also successfully used in timber-frame constructions, where it tightly fills the spaces between structural elements, improving the thermal insulation of external and internal walls. Thanks to its excellent acoustic properties, it is also well-suited for insulating floors and ceilings on timber joists, effectively reducing sound transmission between storeys.

A wide range of thicknesses – from 50 to 240 mm – makes it easy to tailor the material to the requirements of the project, whether in energy-efficient buildings or in developments meeting the nZEB standard.

Key benefits

Unifit 035 combines high technical specifications with features designed to make day-to-day work on the building site easier.

  • The thermal conductivity coefficient λD = 0.035 W/mK ensures very good thermal insulation.
  • It effectively improves the acoustic comfort of rooms.
  • Fire reaction class A1 guarantees the highest level of fire safety.
  • The increased rigidity ensures that the material is securely fixed between the rafters.
  • Wool retains its shape throughout its entire service life.
  • The cutting lines printed on the roll speed up the preparation of the material for installation.
  • Stitching improves ease of installation and reduces the risk of damage to the mat during use.
  • Compressed rolls take up less space during transport and storage.

Technical specifications

Knauf Insulation Unifit 035 has a thermal conductivity coefficient of λD = 0.035 W/mK. The product has a fire reaction class of A1, a thickness tolerance class of T2, a diffusion resistance coefficient of μ = 1, and its tensile strength exceeds twice its own weight.

The mat is available in thicknesses ranging from 50 to 240 mm, with a width of 1,200 mm. Depending on the variant selected, the thermal resistance R ranges from 1.40 to 6.85 m²K/W, which enables the design of partitions that meet current energy requirements.

Certifications and the environment

The product has an Environmental Product Declaration (EPD), DECLARE certification, CE marking (1020 – CPR – 020036600) and a certificate from the National Institute of Hygiene. These confirm both the safety of use and the product’s limited impact on the environment.

Why choose Knauf Insulation Unifit 035?

Unifit 035 is the solution for those seeking highly effective insulation without the need for very thick layers of material. Its low lambda value, wide range of thicknesses, easy installation and long-lasting performance make it ideal for insulating pitched roofs, timber-framed walls and ceilings. Thanks to ECOSE® technology, it is also a more environmentally friendly choice, combining modern solutions with a high level of comfort for building occupants for many years to come.

FAQ – Frequently asked questions about the Knauf Insulation Unifit 035 mat

What is Knauf Insulation Unifit 035 wool used for?
Unifit 035 is a high-quality mineral wool mat designed primarily for the insulation of pitched roofs. It can be used between and beneath rafters, as well as in timber-framed walls, floors and ceilings on joists.
What is the thermal conductivity of Knauf Insulation Unifit 035?
The thermal conductivity coefficient of Unifit 035 is λD = 0.035 W/mK. As a result, the product offers very good thermal insulation when used in a thinner layer than is required for wool with a higher lambda value.
Is Unifit 035 suitable for insulating a roof with limited rafter height?
Yes. Thanks to its excellent thermal performance, Unifit 035 is particularly recommended where the space available for insulation is limited, for example when refurbishing existing roofs.
What makes it easier to install Knauf Insulation Unifit 035 wool?
Installation is made easier by the mat’s increased rigidity, which ensures it remains stable between the rafters, as well as by the ribbing and the printed cutting lines, which allow the material to be quickly cut to the required dimensions.
Does the Unifit 035 provide noise protection?
Yes. Unifit 035 mineral wool improves the sound insulation of partitions, reducing sound transmission between rooms. It can be used, amongst other things, in timber ceilings and timber-framed structures.
Is Knauf Insulation Unifit 035 a non-combustible material?
Yes. The product has an A1 fire reaction class, which means it offers the highest level of fire safety for insulation materials.
What thicknesses of Unifit 035 are available?
Knauf Insulation Unifit 035 is available in a wide range of thicknesses, from 50 mm to 240 mm. This allows you to select the appropriate insulation layer for both standard buildings and energy-efficient properties.
