Whether you're working on a pitched roof, a flat roof, or a loft conversion, Kingspan provides high-performance solutions tailored to meet diverse building requirements.

What is Roof Insulation?

Roof insulation is a material barrier within your roof space. It can be installed between the joists (the horizontal beams along the floor of your attic) or the chevrons (the corner beams that support the roof). In any case, it slows down the heat transfer between your living space and the outside world, creating a hotter home in winter and a cooler one in summer. The insulation between the joists keeps the heat in your living space underneath and creates a cold loft, while the insulation in the rafters keeps you warm in the roof space as well.

Why is roof insulation needed?

In non-insulated houses, approximately one-quarter of the heat loss is attributed to the roof. Insulation in your loft, attic, or roof space is an excellent way to enhance the comfort of your home. It lasts more than 40 years and is expected to pay for itself many times in terms of energy savings, as the cost of insulating attics is relatively low.

When it comes to environmental benefits, sound attic insulation also helps you reduce your house's carbon footprint. This is because the more insulated your home is, the more efficient your heating system will be, which in turn reduces emissions and saves money on your bills.
