30mm Kingspan Thermafloor TF70

  • 30mm TF70 boards are one of the most used products within the construction industry and is well-known for the incredible quality
  • The TF70 insulation boards have a straight edge to ensure boards can be tightly butted together to avoid thermal bridging
  • The 30mm board is for its thinner size, the 30mm can be installed within spaces that contain a smaller cavity which ensures you make the most of you working and living space
  • The low emissivity foil facings are on each side of the board. This reflective, low emissivity surface improves the thermal resistance of any unventilated cavity adjacent to the board
  • Kingspan TF70 means you can improve the thermal quality within the internal structure of the building’s envelope. The boards are also unaffected by air filtration
  • TF70 insulation Boards are lightweight making them super easy to handle, cut, and install. This product will make a projects turnaround times quicker than ever
  • This board offers an incredible thermal conductivity of just 0.022W/mK – which for those who don’t know, means very small amount of heat can pass through the board, keeping the heat inside your home or office!
  • Whilst staying warm in the winter and cool in the summer, you’re also providing an energy efficient environment that contributes to the reduction of climate change
  • While you think it stops at helping the environment, with less heat escaping, Kingspan TF70 boards can also save you money on your energy bills
  • All Cavity boards are CFC, HCFC and Formaldehyde Free with zero ozone depletion potential (ODP) and low global warming potential (GWP)
  • Kingspan Thermafloor TF70 resists attack by mould and microbial growth, and do not provide any food value to vermin, helping to maintain the condition of the buildings structure

How are Kingspan Thermafloor TW70 insulation boards installed in the floor?

  1. Ensure the site is prepared and foundations, where appropriate, built to damp proof course (DPC) level. A thin sand blinding may be used to achieve a continuous smooth level surface, free from projections.
  2. The damp proof membrane (minimum 300 micron / 1200 gauge polythene) should be laid with joints well lapped and folded, to prevent the passage of water, prior to laying the insulation boards. The membrane should be brought up the surrounding walls until it is sufficiently above the height of the walls Damp Proof Course so that it will connect with or form the DPC.
  3. The insulation boards should always be loose-laid break bonded, with joints lightly butted together. If two layers of insulation are required, the next layer should be horizontally offset to the previous layer, the board joints in the two adjacent layers should not coincide with each other. See image below.
  4. A strip of the insulation board (minimum 20 mm thick) should be placed vertically around the outside of the floor slab in order to prevent cold bridging. The top of the strip of insulation board should be level with the top of the floor screed and the bottom should be level with the bottom of the horizontal floor insulation, and closely butted up to it with no gaps.
  5. Insulation boards should be overlaid with a polythene sheet (not less than 125 micron / 500 gauge), to prevent the wet concrete penetrating the joints between the boards and will act as a vapour control layer. Ensure the polythene sheet has 150 mm overlaps, taped at the joints, and is turned up 100 mm at the walls. The concrete slab and screed should be allowed to dry out prior to the installation of the floor finish.

Note –

A face mask or protective clothing is recommended when cutting insulation due to the fibres produced when cutting which can sting the eyes and irritate the skin.

Ensure the wall is sound, secure, free from any contaminants, and dry.

Ensure accurate trimming to achieve close joints and continuous insulation.

How do you cut insulation boards?

The best and easiest way to cut cavity wall boards is to measure and mark the board to size and then score the insulation with a sharp knife, snap the board over a hard edge and score the other side. A fine-toothed saw can also be used to cut the boards. Ensure the boards are marked and measured to size.

What Size Do I Need?

The size you need will depend on the space being insulated. Thicker insulation is always the best option to achieve the best thermal conductivity possible however a thinner board will also improve the thermal conductivity. This decision is really based on how much space you want to save, and if the board meets the building regulations.

Is it worth insulating under floorboards?

The majority of heat loss occurs through the roof. However, some 10 to 20 percent of heat loss is due to your floor. We do not take it into account the draughts coming up through the floor. So, if you are wondering is it worth insulating under floorboards, the answer is yes.

What type of insulation is best for floors?

Insulations boards or EPS sheets are a material that is an expanded polystyrene sheet. It is one of the best-known floor insulation materials because EPS sheets are easy to install and have a high insulation value.
