Kingspan TW55

Therma TW55 keeps walls warm, dry, and energy-efficient without adding bulk. The board locks in warmth, helping prevent cold spots in walls.

What Is Kingspan TW55 Insulation?

Kingspan Thermawall TW55 is an insulation panel designed for wall framing (both timber and steel). It is also installed as insulating sheathing.

It has a PIR foam core, which means it is strong, lightweight, and excellent at reducing heat transfer.

On each side is a thin, low-emissivity foil facing that reflects heat back into the building to enhance thermal efficiency.

TW55 is available in a wide range of thicknesses – from 20 mm up to 150 mm.

What Is Kingspan Therma TW55 Used For?

TW55 insulation is commonly used in:

• Timber-frame walls. The panels fit between studs to keep heat in and draughts out.
• Steel-frame walls. They fit neatly between metal studs without adding extra weight.
• Internal partitions. Only when high thermal performance is required.
• Around windows and doors. Easy to trim for tight reveals and irregular edges.
• Refurbishment work. Great for upgrading older framed walls that need better thermal performance.
• New builds. Ideal for modern steel and timber structures needing reliable insulation right from the start.

How to fix Kingspan TW55?

1. Measure the space between studs.
2. Resize your TW55 insulation. You can score and snap thin boards. If using a thicker panel, cut with a handsaw or insulation saw.
3. Press each board firmly into the cavity to ensure a tight fit between studs. Ensure the foil faces the interior of the building, or follow the manufacturer’s guidance.

TW55 is firm enough to stay in place on its own. But for vertical installations or thicker boards, additional insulation fixings or battens may be needed.

How to cut TW55 insulation?

1. Measure and then mark a straight line where you will cut the board.
2. If installing a thin board, score along the foil facing with a sharp utility knife and gently snap along the line. Thicker boards do not need scoring – cut straight through with a fine-toothed handsaw, insulation saw, or powered saw.
3. Sand any rough edges or smooth with a knife. Remember to wear appropriate PPE when cutting or sanding.
4. Fit the panel into position between the studs. You can make small adjustments by trimming the panel further.
