110mm Recticel Eurothane GP PIR Insulation Board

  • 110mm PIR Boards are an extremely popular product within the construction industry
  • The insulation boards have a straight edge to ensure boards can be tightly butted together to avoid thermal bridging
  • Recticel boards hold a great compression strength and are a well-used product for insulating floors
  • This size is commonly used due to its thinner size, the 110mm can be installed in walls that contain a smaller cavity to make the most of the building’s space.
  • PIR Insulation Boards are lightweight making them super easy to handle, cut, and install
  • This board offers an incredible thermal conductivity of just 0.022W/mK – which for those who don’t know, means a 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, Recticel PIR boards can also save you money on your energy bills

Recticel PIR Board FAQs

How are PIR Insulation Boards installed below floor screed?

Before installing the insulation materials ensure the hardcore is laid and levelled. The concrete slabs should also be complete. Apply sand binding if required. Allow the slab to dry as fully as possible prior to continuing – the normal rate is one day for every millimetre of floor slab Pre-Pre-caste systems or block & beam floors should be installed in accordance with manufacturer’s instructions. A thin levelling screed or grout may be required to ensure the base is level Lay the damp proof membrane (DPM).

Install the Recticel Eurothane GP boards, laid in a tightly butted brick-bond pattern. If the desired insulation thickness comprises two layers, board joints should be staggered, and the thicker layer positioned outermost.
Cut strips of 25mm Eurothane GP to the width of the screed depth and place them around the perimeter to provide edge insulation.
Then go on to install the polythene sheet, pipes, and sand cement / screed. The minimum thickness to prevent cracking is 65mm for domestic applications and 75mm for others

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.

What size recticel board 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.

What is floor insulation?

Insulating a floor means adding a layer or multiple layers of insulating materials beneath the floorboards. this reduces heat levels escaping through the floor into the ground. 15% of heat is lost from a house through the floors. Insulation also acts to prevent draughts coming up through the floorboards.
