Can I use polystyrene for loft insulation?

You can use batts, polystyrene slabs, expanded polystyrene or spray foam to insulate your roof or loft space.

Can you use polystyrene insulation in a ceiling?

Polystyrene insulation comes in rigid sheets and planks which can be used under concrete floor slabs, in exterior walls and cladding and insulation and in ceilings.

Is polystyrene good for wall insulation?

Expanded Polystyrene (EPS) Air is a poor heat conductor and since polystyrene has a high thermal resistance itself, it’s very effective at preventing heat transfer. Expanded polystyrene foam provides great thermal insulation in numerous applications, such as building walls, roofing, and cold storage facilities.

Can you use polystyrene between rafters?

As well as placing insulation in the gaps between the rafters, you can also attach insulation directly to the roof rafters. The easiest and cheapest way to insulate your roof is to insert sheets of polystyrene between the rafters.

Is polystyrene The best insulation?

On its own, polystyrene doesn’t have good acoustic insulating properties because it does not have enough thickness or density. However, when it is attached to rigid materials such as structural insulated panels (SIPs), polystyrene can be used effectively for soundproofing.

Is polystyrene insulation breathable?

The expanded polystyrene OpenTherm releases water vapour through minuscule perforations, without sacrificing thermal insulation. With its vapour-permeable insulation and high breathability, the Baumit OpenSystem ensures a comfortable indoor climate. But it isn’t just the insulation layer itself that aids breathability.

What are the pros and cons of polystyrene insulation?

Polystyrene can add an energy-saving and efficient layer of insulation to a roof.

  • Polystyrene insulation can erode the coating on electrical wiring and possibly cause a fire.
  • The biggest drawback of polystyrene is its inability to absorb moisture.

    • Should loft insulation touch the roof?

    We’ve done some searching and have the answer for you. Attic insulation should not touch the roof. Although it can be tempting to over insulate, resist the urge. Too much insulation hinders airflow and can keep excess moisture from escaping, especially in attics.

    Can you over insulate a loft?

    As long as you ventilate your property properly, you can have as much insulation as you like within reason. The trick with loft insulation is to balance the amount of insulation you have with the amount of ventilation necessary to prevent damp. As long as you get that balance right, you should be fine.
