One Of The Most Commonly Faced Difficulties Is How

Given that current building regulations in the UK require 270mm of insulating glass wool, if a home owner wishes to retain a boarded loft and does not want to use a "spray-on" insulation product up between the roof rafters then there is a choice to be made about which direction to take. This means that where the joists run, your insulation is limited to the thermal properties of the joist timber only and your insulation will be "bridged" by the timber i. It might be that if there is any old fashioned electrical conduit that needs to be worked around, you get even less than 90mm in.- Building the floor level up: Cons1.To sum up, if retaining storage space in your loft is important then you can improve your level of insulation but you may have to compromise on the level of insulation you ultimately have and you have to be realistic about the difficulty and complexity of the DIY task involved.Before reading the article, please note that there are a number of dangers associated with carrying out work in your loft and great care must be exercised.4. The main choices are between:1. cold will be able to be transferred through the timber joists.One of the most commonly faced difficulties is how to add insulating material to a loft space when the floor has already been boarded and the loft is used for storage.e. Your floor stays the same height and therefore no loft height is lost. If you run the additional "packing joists" across the existing joists at 90 degrees, you are able to run wool insulation over the top of the original ceiling joists) which reduces potential "thermal bridging". Follow all safety instructions available from the suppliers of the materials you decide to use and if you have any doubts about your capability to carry out insulation work in your loft safely please consult a qualified builder or insulation contractor.When you are standing in the loft, the depth of the void formed between the plasterboard of the ceiling below and the top of the ceiling joists is usually about 100mm (4"). Using a solid insulating board cut to fit in the void that exists between the joists without raising the level of the loft floor. Building the joists up with additional "packing joists" to create a 270mm void which can then be filled with insulating material and then re-boarded over.2.3. Where a home has been built with traditional 4" x 2" timber ceiling joists you are unlikely to get much more than 90mm of insulation board in between the joists (this will vary from property to property). There are no heavy timbers to work with- Insulating with insulation board between the existing joists: Pros5. Insulating between the roof rafters with either insulating board, spray on insulation products or insulation blanket products. You retain your loft storage space7. The wood required for the "packing joists" may be heavy.
