Do I need to insulate the loft floor, or should I insulate the pitched roof? This is a dilemma faced by everyone who plans to insulate their loft space. The right answer depends on what you aim to do with the loft space, and it would be a shame to leave the loft space empty or unused.
For everyone planning to use their loft and who wants to furnish it, roof insulation is a must. There are various insulation companies (i.e. http://knaufinsulation.co.uk/ ) that can do this for you, yet, there are ways to also do it yourself. The best option would be to actually insulate both the loft floor and the roof in order to prevent the heat from escaping and to secure the floor below as well.
The reason you should have roof insulation is because you are laying the groundwork for any future projects should you wish to repurpose it in the future. It is then a must to insulate the inner surfaces of the roof. The correct approach of doing this is a bit tricky and it depends on a number of factors such as whether the inner roof lining matches the roof structure itself. Lining the inner roof is your best bet to do quality work s this will ensure that water, dust or snow cannot enter your home via the roof. It is also a must to keep the moisture out, which is a natural enemy of insulation.
The ideal roof insulation can be either mineral wool or insulation boards. For some, the insulation boards are best because they can be fitted under the roof structure, while the mineral wool can be easily fitted between the beans of the roof. Remember that you would also require a damp-proof cover or membrane if you go with mineral wool.
The most interesting solution however, which will bring the greatest benefits is when the attic is insulated from the bottom to the top. It might be the most labour intensive and expensive option, however if you plan on using the loft, this is the one for you.
The advantages of this method are clear as the heat in the loft will be generated and will be free to circulate without dissipating from the floor or roof. If you insulate the roof and floor, heating in this room will most likely be unnecessary especially if the room is designated to be a bedroom. Therefore, the heat generated will probably be generated from rooms below and the loft will act as the perfect buffer, while being functional.
On a final note, one must pay attention to safety. Insulation must be installed correctly to meet most standards. While your insulation might be a nice DIY project, having an insulation set up by a experienced installer is much safer and will often be under warranty as well. Looking for a installer with a license is even better and this really cuts down on the costs of purchasing specialised equipment such as protective clothing or masks.
Roof insulation will ensure that you will have pleasant summers and warm winters while also saving you a lot of money and opening up another space in your home.
