A useful starting point
Which insulation
do I need?
Start with where the material will go. Then compare the specifications for your construction.
EXPLORE INSULATION ROLLS
Insulate the space above your ceiling.
Start with Aerolite or Knauf glasswool rolls. Compare product R-values, thickness and coverage per roll. The right specification depends on your roof, ceiling and project requirements.
EXPLORE INSULATED CEILING BOARDS
A ceiling finish with insulation built in.
Explore Isoboard and Summit XPS. Compare board thickness, length and finish, then confirm the support spacing and fixing method for your ceiling. Board layout affects the quantity and offcuts.
EXPLORE ACOUSTIC INSULATION
Plan for the complete wall or ceiling system.
Start with the listed Knauf acoustic insulation. Sound performance depends on the full construction, including the lining, framing, seals and openings. Insulation alone does not make a room soundproof.
Measure once. Order with confidence.
Start with your
ceiling area.
Enter the length and width of a rectangular area to estimate the square metres to cover. Add an allowance if your layout calls for it.
For insulation rolls, choose a listed roll option to estimate whole rolls. Use the product page to confirm the specification and quantity before ordering.
Ceiling boards need a layout calculation: area alone cannot account for board direction, lengths or offcuts. For several rooms, measure each separately.

Before you order
A few useful answers.
Choosing your insulation and ceiling materials should feel straightforward.
Can I buy ceiling insulation online?
Yes. Browse the published products, choose a suitable thickness and check the coverage, price and ordering options on the product page. Aerolite and Knauf are our main ceiling insulation roll ranges. Availability depends on the selected option.
Shop ceiling insulation →Should I choose Aerolite or Knauf insulation?
Compare the specific products for your project: thermal performance, thickness, coverage per roll and price per m². The brand name alone does not tell you whether a particular option meets your requirements.
View Aerolite · View KnaufWhat is the difference between rolls and XPS ceiling boards?
Insulation rolls are typically fitted above a separate ceiling. XPS ceiling boards, such as Isoboard and Summit XPS, can provide the visible ceiling finish and thermal insulation in a suitable installation. Compare the complete construction, product specification and fixing instructions.
How much insulation do I need?
Measure the area to cover, allow for the actual layout, then divide the required area by the selected roll’s coverage. Round up to whole rolls. Use our area planner as a starting point. For ceiling boards, use the product’s board layout calculator because lengths and offcuts affect your order.
Try the area planner →How are delivery costs confirmed?
Delivery options and costs depend on your order and location. Confirm arrangements before placing your order. Long ceiling boards and bulky rolls may need different transport arrangements.
