Attic Insulation is an extremely effective method of reducing the cost of heating your home. Cold attics are attics that are not converted to living spaces nor do they have a heat source. These attics should be insulated at floor level, therefore, keeping the heat in the living area beneath & not in the attic.
The current recommended minimum depth of attic insulation is 300mm achieving a minimum u. value of 0.14. This should be installed in 2 layers, 1 layer fitted snugly between ceiling joists & cross laying the second layer @ right angles to the first layer thus eliminating cold bridging & heat leakage. Fibreglass is available in different depths for different top-up requirements.

Ventilation in attic areas is always worth checking also. An unventilated attic will lead to attic condensation & moisture build up which the roof timbers could eventually absorb & lead to further problems.
Recent trends have led to dramatic growth in the utilisation of the roof space as a living area & roof conversion. Proper insulation can make a massive difference in these rooms all year round & make them much more comfortable spaces.
The installation of insulation in loft rooms & roof conversions is a specialist task & is not a DIY project as there are considerations from ventilation, fire protection & building regulations. Several products are available depending on the roof design & construction.

Other Attic Considerations
Sheehy Insulation use attic stair hoods made in Fermoy. These are an insulated tent like hood which sits over the attic stairs eliminating drafts & breezes from the cold attic above.
Standard Trap Doors
Trap Doors are backed with fibreglass & edged with a draught seal strip to ensure a draught proof door.
Down Lighters & Recessed Lighting
Down Lighters are huge heat loss contributors. A Rockwool fire proof tube can be fitted above the light to stop breezes & draught being felt below them.
