50mm GreenGuard GG500
Kingspan GreenGuard GG500 is a high-performance rigid insulation board made up of extruded polystyrene designed for exterior insulation including the insulation of inverted roofs, basements, car park decks, and heavy-duty commercial, industrial, and cold store flooring. The GG500 boards have excellent compressive strength and a closed cell structure that is moisture resistant and rejects the absorption of groundwater and the passage of water vapour. The board is a chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC) free and manufactured with a blowing agent that has zero ozone depletion potential (ODP) and low global warming potential.
- High performance rigid extruded polystyrene insulation with low thermal conductivity.

- Easy to handle and install.
- Rebated Edges
- Compressive strength (minimum) at 10% compression – 300kPa
- Fibre-free rigid extruded polystyrene insulant
- Resistant to most dilute acids and alkalis
- Available for new builds or refurbishments
The Kingspan GreenGuard brand selection offers extruded polystyrene (XPS) insulation boards in a range of sizes, air barrier building wraps and accessories including flashing.
The XPS insulation board offers an R–value of 5.0 per inch of thickness and is the ideal product for a variety of applications including below slab, below grade along the foundation, inside basement walls, exterior insulation over wood sheathing and residing.
Rigid extruded polystyrene insulation (XPS) can also be used as general-purpose insulation for multiple applications including, roofing, wall and foundation applications requiring a minimum compressive strength.
Continuous insulation for above grade walls, as well as below grade walls and floors provides an extra barrier against moisture infiltration.
Each insulation product achieves the necessary fire performance for its intended application.
GreenGuard products are easily identifiable by their bright green colour. In addition to creating healthier, durable, and cost-efficient assemblies, GreenGuard products can help projects to meet environmental building certification requirements.
Kingspan Greenguard GG500 can be cut by measuring and marking to board to ensure an accurate fit and cutting with a fine-toothed saw on higher surface to allow the saw to cut through. Other ways to cut GG500 is to use a hot wire system or by scoring with a sharp knife and snapping the board over a straight edge and scoring the other side if necessary. Ensure accurate trimming to accomplish close-butting joints and continuity of insulation to avoid thermal bridging.
Packaging and Storage:
The polyethylene packaging of Kingspan Insulation products is fully recyclable and packaging materials should not be considered sufficient for outside protection. The boards should be stored on a flat surface inside a well-ventilated building. If, however, indoor storage is not an option, then the boards should be stacked clear of the ground and protected with a pale pigmented polythene sheet or weatherproof material. Kingspan GreenGuard should not be left exposed to the sun covered by either a transparent or a dark plastic sheet. In both cases the temperature of the board can build up and alter the board dimensions or warp them.
Please note Kingspan GreenGuard may be delivered in packaging showing alternative branding.

Installation Guide below a floor slab
Before the installation begins make sure that the site is prepared and foundations, where necessary, are built to damp proof course (DPC) level.
A thin sand blinding may be used to accomplish a continuous level surface that is free from projections over rolled hardcore.
The damp proof membrane (minimum 300 micron / 1200 gauge polythene) should be laid with joints well lapped and folded either directly over the well compacted hardcore prior to laying the insulation boards, or over the insulation boards. This will prevent the passage of ground water.
The membrane should be brought up the surrounding foundation walls until it is sufficiently above the height of the wall DPC so that it will connect with or form the damp proof course.
The insulation boards should always be loose-laid, break bonded, with joints lightly butting together.
If two or more layers of insulation materials are required, they should be horizontally offset relative to each other so that the two layers do not line up. The horizontal centre of the new board should line up with the join of the two butted boards below and should overlap the vertical joins of the board below.
To prevent thermal bridging. A strip of rigid insulation board (minimum 20 mm thick) should be placed vertically around the perimeter of the floor slab. 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.
If the DPM is laid directly onto the hardcore below the insulation boards, the boards should be overlaid with a polythene sheet (not less than 125 micron / 500 gauge), to prevent the wet concrete piercing through the joints between the boards, and to act as a vapour control layer. Ensure the polythene sheet has 150 mm overlaps and is taped at the joints and is turned up 100 mm at the walls.
The subsequent installation of the concrete slab and screed or other flooring material is carried out in a manner similar to that for an un-insulated floor. The concrete slab and screed should be allowed to dry out prior to the installation of the floor finish
