Breathable Roof Insulation

Internal insulation to old house walls.

Breathable roof insulation.

Breathe r gives a overall thermal resistance value of 0 450 m2 k w equivalent to approximately 20mm eps expanded polystyrene insulation. Over the top of the insulation the breather membrane batons and cladding is installed. It comes in all forms but you will be familiar with the foam insulation panels with silver foil on both sides we see them all the time in houses with damp problems. As this requires fitting insulation above the rafters the roof covering will have to be removed in order to fit the insulation.

The bb range is most commonly used to insulate walls externally as to allow any moisture build up inside the wall or studwork to escape. Our breathable multifoil insulation range achieved a w1 waterproof rating which means that it is suitable for both roofs and walls. A breathable insulating membrane is ideal in these circumstances. Why breather membranes are required moisture often passes into the roof space as vapour and then condenses when it reaches a cool surface.

Insulating an old house breathability. It has not only a insulation benefit but also a structural benefit as it provides a diaphragm rigidness to the walls. Breathe r s internal layer is manufactured using highly reflective insulation grade aluminium foil which is fully perforated to allow free passage of moisture from the internal to external. The hygroscopic nature of the wall will then facilitate the safe movement of moisture to the outside surface to be wicked away for example through a lime render or directly from the building surface behind a ventilated façade.

Building regs review hackitt conflict. Woodwool boards great for infill panels. This roof type will require a breathable membrane like kingspan nilvent to be fitted above the insulation. Modern insulation is the work of the devil in this regard.

Sheepwool insulation and moth infestation. Breathable membranes or breather membranes have been designed to improve ventilation and reduce condensation build up within the roof space as well as ensuring insulation remains effective. Sheepswool its green clean and breathable. Hemp fibre boards breathable roof insulation.

Sf19bb s new construction and design outperform other manufacturers with its excellent r value of r 2 53 for a wall and r2 22 for a roof. We constantly battle modern insulation. Flexible multifoils can cope with this as well as providing an airtight construction method that compensates for the deficiencies of other insulating materials. Sf19bb is superfoil s first fully breathable insulation for use in roofs and walls.

Natural insulation used in a breathable vapour open structure does not require interstitial gaps or spaces the wall section can be fully filled. It is a high performance and very competitive breathable insulation. The construction build up for this can be seen on our online u value calculator.
