Insulation In Ceiling Joists Guide

This article will run through the ultimate insulation in ceiling joists guide. If you do have any questions after reading please get in touch with one of our industry experts.

When it comes to lofts and attics, us Brits seem all too often to leave the highest rooms of our house in the dark… using them solely for the odd bit of storage.

But then, they’re normally cold and a bit damp, so it’s understandable. However, Nationwide’s latest property survey has shown that transforming a loft conversion into a fully functional living space can add a whopping 21% to a property’s value.

With Winter just around the corner, there’s never been a better time to ditch your floorboard’s scratchy fibreglass insulation, and replace it with a more efficient alternative, that stands the test of time.

With that in mind, we’ve compiled the following guide exploring how to install insulation in ceiling joists, including options on offer, problems and plus points, and, ultimately, which one performs best in practice…

Attic Insulation – Insulation In Ceiling Joists Then And Now

The most common insulation product in the UK is the cotton wool looking fibreglass rolls, cut to size, and then wedged between the floorboards in the loft, up to 10 inches in depth.

However, this leaves the room above it un-insulated, and therefore incredibly cold, and is a product that degrades and breaks down overtime – and is unsafe to touch or inhale.

Instead, those looking for to convert their loft into a usable room should insulate between the rafters of the roof and remove the insulation from between floorboards. This frees up space, but also keeps the room below it as insulated as the rest of the house.

The most efficient way of fitting insulation between rafters is using a product type that’s already found popularity in colder countries, such as Norway and Canada. 

Spray foam insulation is an industrial foam that can be sprayed directly up between the roof’s rafters, and will stick to them, expanding before drying out. It sticks to the roof surface and to the rafters around it, forming a seal against air flow and moisture from the roof, entering the room below.

Increased Comfort, Decreased Bills

No matter how cold the air, or how heavy the water coming into contact with the outside of the property, spray foam insulation remains impermeable, and protects the space beneath it.

Attic rooms are often difficult to heat due to their high or awkwardly-shaped ceilings, but this doesn’t need to be the case once properly insulated.

Those with spray foam insulation already installed in their properties claim saving up to 40% on their heating bills, as the hot air is unable to leak out and escape, and the external cold air is unable to seep in. This makes your heating more effective, and when used with a temperature control system, requires less energy usage overall.

Our existing customer, Ricardo, who had spray foam insulation sprayed directly between his roof rafters reviewed the insulation’s performance on TrustPilot, writing:

Absolutely fantastic, I noticed a difference straight away in the atmosphere of my home it felt just a little warmer, (not sure if it were the placebo effect, knowing it had just been installed and willing my home to be warmer or whether it really did work.)

Enlist The Help Of The Experts!

To spray this multi-purpose product directly between the roof rafters in the loft, specialist equipment is required to blend the chemicals in equal parts with water.

As with any job using a chemical mixture, a specialist technician is required. The British Board of Agrement (BBA) accredit spray foam insulation technicians

Our talented team of technicians can remove any existing fibreglass insulation safely, and allow you to reclaim the 10-inches of depth that it has previously taken up.

This combined with an insulation seal to maintain an ambient environment within, the attic is ready for daily use however you’d like – be that an extra bedroom, living room or office.
