Slow heat transfer through the ceiling
A continuous insulation layer helps limit heat moving between your rooms and the roof space. Its contribution depends on the selected specification, fitting and the rest of the building.

Built around your roof space
Knauf insulation installers with the whole job in mind.
Choosing ceiling insulation involves more than the name on the pack. Roof access, usable depth, existing material and the performance required all influence a successful installation.
Our Knauf insulation installers help you connect the product choice to the work on site. We discuss what is above your ceiling, establish the area to cover and explain the fitting and preparation included in your quotation.

Why choose Knauf ceiling insulation?
Comfort above you.
A difference around you.
Knauf Ceiling Roll is glass mineral wool made with ECOSE® Technology. Our Knauf insulation installers help you assess it for the ceiling and roof construction you have.
Glass mineral wool with ECOSE®
This ceiling roll uses Knauf’s bio-based binder technology. The flexible blanket format can be fitted around the roof layout while retaining the intended insulation thickness.
Know what the rating describes
The range has a Euroclass A1 reaction-to-fire classification. That is a material classification; any required fire resistance of the complete ceiling must be addressed by the specified ceiling system.
A practical supply-and-fit service
From an existing home to a new working space.
Our Knauf insulation installers help homeowners and building teams plan ceiling-level insulation. Share the building type and project stage so the installation can be considered alongside access and other work.
Upgrading an existing ceiling
Our Knauf insulation installers consider the hatch, roof height, obstructions and condition of any existing blanket. An accessible loft can often be upgraded without replacing the ceiling below; suitability needs checking first.
Renovations and new ceilings
Insulation is easier to coordinate when it is included in the building programme. We discuss the agreed roof specification and timing with you so access, services and ceiling work can be planned together.
Offices and commercial properties
Send the ceiling construction, working hours and access restrictions with your enquiry. The selected product must suit the actual application; commercial layouts may need a project-specific specification.

A clear route from enquiry to fitting
How our Knauf insulation installers plan your installation.
Good preparation helps the work run smoothly. We establish the scope before material is ordered or an installation date is agreed.
Share the starting point
Your location, approximate ceiling area and a building plan or photographs help us understand the space. Tell us about any specified product and the timing of other trades.
Review the conditions
Our Knauf insulation installers assess the information and confirm whether a site visit is needed. Access, existing insulation and roof condition help establish what the job involves.
Confirm the details
Agree the product range, thickness, coverage and fitting scope. Preparation, removal or ceiling repairs should be clearly identified where they are needed and costed separately when appropriate.
Install with care
Fitting follows the agreed specification, with attention to joints, edges and service routes. We consider the relevant ventilation and equipment clearances as part of the work.
Details that make the installation
Close-fitting coverage.
Room for the blanket to work.
Our Knauf insulation installers look beyond the open centre of the loft. Edges, changes in direction and obstructions need consideration so the agreed coverage is achieved without unnecessarily compressing the material.
Known leaks and electrical defects need attention from the relevant trades. Access routes, ventilation openings and equipment clearances should be planned before the blanket goes down.

Useful answers before you book
Questions for our Knauf insulation installers.
Unsure about access, thickness or the work involved? Start here, then get in touch about your property.
Can you supply Knauf insulation and fit it?
Yes. Our Knauf insulation installers can prepare a combined material and fitting quotation. The selected product, area and preparation are established before the work is booked.
Is 135mm Knauf the right choice for every roof?
No single thickness suits every project automatically. We consider the required thermal performance, existing construction and available depth. Share the designer’s specification where one has been provided.
Can existing insulation stay in place?
That depends on its condition and the proposed build-up. Our Knauf insulation installers assess whether the existing material is suitable to retain and whether preparation or removal needs to be included.
What is the difference between Uncut and Combi-cut?
Uncut is a full-width roll cut to suit the job. Combi-cut has partially cut sections that can be separated. The choice depends on the roof layout and the format available for the specified product.
Can you install it without replacing the ceiling?
Often, where the roof space has suitable access and working room. The hatch, roof structure and existing services need checking. Enclosed or inaccessible sections may need a different agreed approach.
How long will the installation take?
Timing depends on the area, access, obstructions and preparation. We discuss the expected programme after reviewing the job, including any coordination needed with other trades.
What should I prepare before installation?
Clear the agreed access area and flag any known roof or electrical issues. Our Knauf insulation installers will explain the arrangements for your property before the installation date.
Can I order Knauf rolls without fitting?
Yes. Visit our Knauf insulation product page for roll options and the quantity calculator, then request a material quotation.
