Why Use Insulated Concrete Formwork Walls?

by Peyton Sanders

Formwork concreting techniques give you an easier build. This moulding and setting process helps you size and build concrete walls efficiently and quickly. While regular formwork has its benefits, insulated systems have some extra advantages.

How does insulated formwork work and why should you use it?

What Is Insulated Formwork?

Formwork products work like moulds when you pour concrete. So, if you're building a wall, you install a form casing made to the right size and depth. You then pour concrete inside. The form holds the concrete in place while it sets.

If you use regular forms, then you usually peel off the mould when your wall has set. These moulds are typically made of strong cardboard. Insulated forms do the same job but work slightly differently.

Here, the mould casing is made from a specialist insulating material. You pour the concrete into the mould as usual; however, you don't take the form off at the end of the setting process. You leave it in place. It then provides automatic insulation that is bonded to the wall.

Why Use Insulated Formwork on Your Walls?

Insulated formwork speeds up your build and makes it more cost-efficient. Like any formwork, this technique helps you create walls of exactly the right depth, height and shape. You won't need to do any extra work on the walls to get them into the right shape at the end of the setting process.

You won't have to budget to buy stand-alone insulation to add after the build; it comes with the forms. Plus, your labour costs will be lower. You don't need to allocate some of your crew to add insulation once the concrete has set. You save time and money.

This kind of insulation also makes your overall build more energy efficient. The insulation is tightly bonded to each wall. It automatically sets on to the concrete. This creates a robust insulative barrier.

So, your walls become more thermally efficient. The interior layer of insulation keeps heat and cooled air inside the property; the exterior layer keeps excess heat and cold outside of it. These layers also provide some noise insulation.

You should also see less dust coming into the property through the walls. The form casings make the concrete less porous. So, less air and concrete dust come inside. This is especially useful for anyone living or working on the property who has dust allergies.
