Loft roll or Celotex boards: the right insulation for the job
The condition of the loft, how you use it and where the insulation needs to go all affect the specification. I’ll look at the existing insulation, roof construction and access before recommending materials and thickness.
Ceiling-level insulation
Loft roll installation & top-ups
Mineral wool loft roll is a practical option for many unheated lofts. It is laid between ceiling joists, with further layers across them where specified, to reduce heat escaping from the rooms below.
I can install a new layer or assess an existing loft for a top-up. Sound, dry insulation may be retained where suitable. Coverage, gaps and airflow at the eaves are checked as part of the work.
The roll is fitted to its intended thickness, with ventilation routes kept clear and access needs considered.
Rigid board insulation
Celotex PIR board insulation
Rigid PIR boards, commonly known as Celotex, can suit roof slopes and other loft details where the construction calls for them. A suitable design may include insulation between and below the rafters.
The board specification, thickness, position and joints are selected for the roof build-up. Ventilation, air and vapour control, and the internal finish are considered together.
Your quote confirms the product and work included. We can discuss board insulation alongside re-roofing work where appropriate.
A check of the loft before installation
Adding insulation is a good time to check what is happening in the roof space. I look for signs of leaks or damp, blocked ventilation and gaps in the existing insulation. Any concerns are explained before the work is agreed.
- The condition and depth of existing insulation.
- Airflow at the eaves and other ventilation routes.
- The loft hatch, storage and safe access requirements.
- Pipework, cables, downlights and other services that need suitable clearance or attention.
If the roof is leaking, the cause needs dealing with before it is covered up. See our roof repair service. Any additional preparation or specialist work needed will be discussed and set out in the quote.
How much does loft insulation cost?
The price depends on the loft area, existing insulation, access, material and preparation needed. Topping up an accessible loft with roll is a different job from insulating a sloping roof with rigid boards and associated layers.
Send your postcode, approximate loft size and a brief description of what is there now. Photos can help with the initial enquiry; a visit may be needed to confirm the scope. You’ll receive a written quote explaining the proposed insulation, thickness and what is included.

Loft insulation: common questions
Can you top up the insulation already in my loft?
Yes, where the existing material is suitable. I check its condition, coverage and depth first. Damp or damaged insulation and any underlying roof problems need assessing before more insulation is added.
Is Celotex better than loft roll?
They suit different applications. Loft roll is commonly used at ceiling level in an unheated loft. PIR boards can suit roof slopes and other specified details. The right choice depends on the roof construction and what you want the loft to do.
How much insulation will I need?
The product, required performance and roof build-up determine the thickness and layout. A depth of loft roll cannot simply be swapped for the same depth of PIR board. The proposed specification will be explained in your quote.
Can I still use my loft for storage?
Tell me about storage and access before quoting. Loft roll needs room to retain its thickness rather than being compressed beneath boards. Suitable raised boarding or access arrangements may need to be considered and priced separately.
Will insulation solve a damp or leaking loft?
A leak or condensation problem needs its cause assessed. The roof should be in suitable condition and ventilation needs checking before insulation is installed. I’ll explain any work needed before proceeding.
