Insulated Concrete Forms
ICF blocks are increasingly being used in new construction projects, both residential and commercial in the Cayman Islands. The concept of these blocks is simple: 5-inch thick blocks of foam are connected through webs.
The blocks are stacked and then reinforcing steel is run through the gap between them. Concrete is then poured through the middle of the block. The resulting walls are not only extremely strong and resistant to hurricanes, but thanks to the insulation provided, they also significantly reduce energy costs.
No matter how well insulated the walls are, if the floor or ceiling doesn’t enjoy the same level of insulation, the cool air will escape and the warm air will creep in. CayDeck is the perfect complement to ICF walls, and provides an added level of insulation for decks, floors and roofs.
Cinderblocks and CMU have no R value (an insulation rating) whereas ICFs and Cay Deck mean you build insulation values right into the building.
What if the building is already built? Older buildings, and those that were built without ICFs still have the option of building in insulation at a later date. Flat foam sheets are an easy way to increase the level of insulation of without having to pull down and rebuild walls.
The foam sheets can simply be adhered to the exterior walls which can significantly reduce the costs of keeping the building cool as well as providing a degree of soundproofing.
