Kingspan’s Therma range includes a variety of high-quality products designed to fit many applications. Within the Therma range there are three main products that are widely held products within the construction industry – TP10, TF70, and TW55. The Therma PIR board is Kingspan’s highest performing insulation board designed for multiple applications –
The fibre-free insulation boards are made of a rigid Polyisocyanurate (PIR) core bonded to low emissivity foil facings, manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). The entire Kingspan Therma Range can be applied to extensions, refurbishments, and new build projects within residential, commercial, and industrial buildings.
This range of Therma products – TP10, TF70, TW55 – are effectively the exact same board with three different codes indicating the boards possible use. The board codes illuminate questions and confusion regarding where the boards can be used however, due to the likeness of each board, they can all be used as an alternative to the other.
- 140 kPa at 10% compression
- Non-deleterious material
- Rectangular shape with squared edge
- Manufactured with Niflam technology
- Indefinite life span when installed correctly
- Resistance to solvents, fungi & rodents
- Multiple application methods
- Energy efficient
- Can improve the standards of the current building regulations.
- Reduce energy bills up to 30%
The Therma range is easy to cut and install. The boards are cut by scoring the board, snapping over a hard edge, and then scoring the other side. Another method for cutting these boards is measuring and marking the boards to size and cutting with a fine-toothed saw.
All Kingspan Therma boards should be stored tacked on a flat level in a dry environment. If outside apply to required weatherproof coverings. Do apply excess weight or stand on the boards to avoid damage.
At Insulation Board, we always try to guide our customer on how to install products however, please note this is a guide only. ALWAYS consult a building professional before installing TF70, TP10, TW55.

TP10 Insulation – Thermapitch
The TP10 roof insulation boards are 2400mm x 1200mm with a range of thicknesses from 20mm to 165mm. The TP10 boards have an incredible thermal conductivity of just 0.022W/mK. Thermapitch has an approximate weight of 3.50 kg/m2 at a thickness of TP10 100mm.
The Thermapitch TP10 applications include
- Between rafters, no sarking board
- Between rafters, 18mm sarking board
- Partial fill between rafters, no sarking board
- Partial fill between rafters, 18mm sarking board
- Between and over rafters at 400mm centres
- Between and over rafters at 600mm centres
- Dwarf wall, between and inside studs
- Loft floor or flat ceiling, between and over joists
The TP10 boards should first be measured and cut to size.
When cut, push the TP10 board tightly fitted into the back of the cavity either between the rafters or within the stud wall. Make sure all boards are tightly butted together at the joins. The board joins can be taped to avoid thermal bridging. Continue to do this until the entire section is filled.
The boards / rafters can then be horizontally overlapped with TP10 insulation boards, or insulated plasterboards (K118) if turning the space into a room in the roof.
Can you use Kingspan TP10 on a flat roof?
Despite the Thermapitch name, TP10 is suitable for use in rafter level warm roofs and in cold flat and pitched roof applications.
What is pitched roof insulation?
Rafter insulation refers to the pitched part of a roof, when insulated with boards, slabs or rolls.
Rafter insulation helps to provide durable insulation between, above and below the rafters to avoid heat and energy loss.
TF70 Insulation – Thermafloor
The TF70 floor insulation boards have a selection of thicknesses from 20mm to 165mm. The boards are 2400mm x 1200mm with a thermal conductivity of 0.022W/mK. The 100mm boards have a weight of 3.50 kg/m2.
The Thermafloor TF70 applications include:
- Beam and dense block ground floors
- Suspended timber ground floors
- Solid concrete ground-based floors
- Insulation below the floor screed
- Timber floors on battens
- Timber floating floor
First, measure and cut the TF70 boards to size.
A damp-proof membrane should be laid folded with well lapped joints and brought up around the edges. Placed required insulation vertically around the perimeter of the room. The top should be level with the top of the floor screed. The bottom should be level with the bottom of the horizontal floor insulation.
The insulation boards should be loose-laid, break-bonded, with joints tightly butted. Lay an additional layer of insulation horizontally offset so that board joints in adjacent layers do not coincide with each other. Polythene should be laid over the insulation boards with 150mm overlaps in breaks and taped at the joints and is turnt up 100mm at the walls. Finish with a sand and cement screed.
Is TP10 the same as TF70?
Available for three different applications: Kingspan Thermapitch TP10 is suitable for tiled or slated pitched warm roof spaces. Kingspan Thermafloor TF70 is used to insulate solid concrete and suspended timber ground floors. Kingspan Thermawall TW55 is used to insulate timber and steel framing systems.
TW55 Insulation – Thermawall
The TW55 wall insulation boards are 1200mm x 2400mm. The thermal quality of the boards is 0.022W/mK. TW55 comes in a wide range of thicknesses – 20mm, 25mm, 30mm, 40mm, 50mm, 60mm, 70mm, 75mm, 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, 150mm and 165mm.
The Thermafloor TW55 applications include:
- Partition wall applications
- Solid wall applications
- Between timber frame studs and sheathing
- Between timber frame studs with K118 Insulated plasterboard
- Between timber frame studs and sheathing
- Insulated sheathing on steel frame
- Insulated sheathing on timber frame
Measure the space and cut the TW55 insulation board to size.
Insert the insulation into the timber or stud wall. Tightly fit the insulation and tape at the joins avoiding thermal bridging. Continue until the wall is filled with TW55 insulation boards. Plasterboard, or insulated plasterboard (K118) can then be fixed horizontally cross the stud frame. The wall can then be decorated to complete.
What is sheathing in a wall?
Wall sheathing is a structural material. Sheathing is used in exterior wall framing to prevent walls from swaying or bending. Builders use sheathing as a nailing base for siding to creating the walls of a building.
Can Kingspan TP10 be used on walls?
Thermapitch TP10 boards are used to insulate tiled or slated pitched roofs however they can also be used to insulate walls, attic floors, dormer windows and flat ceilings as well as a variety of other applications.
