Kingspan Greenguard
Kingspan GreenGuard is a type of insulated extruded polystyrene (XPS) panel. Greenguard’s outstanding compressive strength qualifies it for use in specialist flooring systems.
What is Kingspan GreenGuard Insulation?
GreenGuard is a dense panel with enhanced stability and resistance to water. Due to its reduced water absorption, it is best suited for use in foundations and basements.
What is GreenGuard Insulation Used for?
Kingspan GreenGuard insulation is used in different ways, including:
- Parking structures
- Heavy duty flooring
- Commercial flooring
- Foundations
- Load bearing applications
- Exterior insulations
Types of Kingspan GreenGuard
Kingspan’s GreenGuard line of insulated boards comprises GG300, GG500, and GG700.
All three can withstand vehicle loads and are optimised for flooring applications that require high compressive strength and durability.

FAQ:
What is Kingspan GreenGuard?
GreenGuard Kingspan is an XPS board with remarkably high compressive strength and moisture resistance. These unparalleled properties enable it to perform exceptionally well in areas with strict load bearing structural requirements and those at high risk of water exposure, such as foundations and basements.
How to install Kingspan GreenGuard
There are three main ways to install GreenGuard boards: through mechanical fixing, by adhesive bonding, and loose-laid installation.
1. To fix GreenGuard mechanically
This method is usually used on framed substrates, walls, and some roofs.
- Clean the substrate or framing and let it dry.
- Place your GreenGuard panel against the wall or studs.
- Fix the board to the wall using screws or ring-shank nails, spacing them uniformly across the surface. This will prevent bowing.
- Seal the joints with GreenGuard seal tape or other compatible jointing tape.
2. To fix GreenGuard with adhesive
This method is normally used on retrofit upgrades, masonry walls, and areas where fixings cannot be used.
- Run beads or dot and dab a Kingspan-approved adhesive across the back of the board.
- Firmly press the GreenGuard against the substrate to make sure the adhesive holds.
- Keep the boards close together and level.
- Seal with approved tape or flashing.
3. To loose lay GreenGuard
This method applies to floors, below-grade areas (basement floors, under slabs), and some inverted roof systems.
- Clean and level the base.
- Fit the boards from edge to edge.
- Stagger the joints so the boards do not form vertical lines across layers.
- Add a second layer if needed, offsetting it to prevent aligned seams.
- Lay the subsequent floor layer: screed, membrane, or protection layer.
What is GreenGuard insulation made of?
Kingspan GreenGuard insulation is made from polystyrene, which is a type of synthetic polymer. The polystyrene is first heated to a molten state and mixed with various additives. After a series of treatments using controlled heat and pressure, the mixture is extruded, allowed to cool and solidify, and then cut into different sizes.
