An Essential Guide to Roof Insulation For Your Home
In this article we are going to supply you with the essential guide to roof insulation for your home - giving you the tools you need to make the correct decision for your home.
The idea that heat can rise, and simply leave our homes, is something that is overlooked far too frequently. In fact, it was once deemed adequate to simply have a layer of fibreglass insulation to heatproof the home.
However, more and more families are being made aware of the importance of having a high standard of roof insulation. With that in mind, here is your essential guide to roof insulation!
It is widely known that one of the highest recommended areas in the house to insulate is the loft. We use our lofts and attics for different activities, such as storing Christmas decorations, or even transforming the loft into a living area.
Regardless of how you use your loft space, not all roofs are the same, and needless to say, different roofs require different ways of looking after them.
Therefore, weaving insulation into the equation, whether it be an old roof, or a brand spanking new roof, should be at the forefront of your thinking. Here’s how to tackle the task at hand, with the help of reputable roof insulation contractor…
We Need To Breathe – So Do Roofs!
However you decide to treat your roof, or what you use, ventilation is crucial in the performance of your roof. There needs to be an adequate amount of air movement in order to radically reduce the likelihood of condensation, as this can inevitably start to attack your structure.
The first thing you should do before undertaking any work yourself, or outsourcing to a professional company, is have your roof inspected for any potential leaks, hazards or ventilation issues that have already occurred.
Installing Roof Insulation: The Process
No essential guide to roof insulation would be complete without talking about the process. Insulation is widely known as a cost-effective way of saving money on your energy bills. Thankfully, the installation process itself is relatively simple.
However, before installing new insulation, it is highly advised that you clear out the installation space free of debris and old insulation, as this can counter-act the performance of the new product.
Normally, the most common way of insulating a loft space is by laying batts or quilts of insulation both between and over the loft joists. If you own a building that already breathes properly, then permeable insulation works best in these conditions.
The Blown-in Approach
An alternative option of insulation, however, is loose fill or blown insulation. The insulation can be sourced from a variety of materials but again, the most common materials for this method of insulation is mineral wood or the cellulose fibre from recycled materials such as newspaper.
The advantage of this method of insulation is that it fills all the gaps that are a lot trickier to fill using batts. The downside, potentially, is that the loose fill insulation can be blown around the space, via the movement and flow of air.
This tends to be the case in draughty spaces, which leads to an uneven level of insulation.
It’s All In The ‘K’
A loft space’s thermal performance is measured on a ‘K’ basis. The lower the K value, the more heat your loft space will be able to withhold. Regardless of which insulation you choose, it should achieve a minimum value of 0.16 W/m²K.
In order to meet this standard, more than one layer of material does need to be installed, and if you’re using batts, it is advised to install them at 90 degrees of one another, to reduce the gap size dramatically. It is important that any piping in the space is insulated too, including over any water tanks.
However, do not insulate underneath the tanks, as warmth from below can reduce the risk of freezing the tank. It is also important to remember not to allow the insulation to block the eaves’ ventilation holes, as this would remove the point of insulation altogether.
Are You Due An Upgrade?
Over the past 50 years, new-building insulation levels have increased on a steady basis from around 25mm to 270mm in today’s builds.
Although old buildings don’t necessarily need to meet the new building regulations, it’s nothing short of common sense to simply top up the existing insulation to a thicker standard.
However, if any existing insulation is in an unserviceable condition, a complete insulation replacement is recommended.
Transform Your Loft Into A Habitable Hideaway!
If your loft space is a habitable living area that has been transformed with the roof re-done, then the recommended method is to insulate below or between the rafters – or both, if you prefer.
However, take into consideration that below-rafter insulation will lower the height of the ceiling.
Again, regardless of the insulation method, ventilation is crucial, so make sure an air gap of 5cm between the insulation and the roof covering is present.Related Home Logic Living Articles
