Breathable membrane and multi-foil over rafter are two different types of roofing systems that can be used to insulate a roof and prevent heat loss.

Breathable membrane is a material that is installed on the roof to prevent moisture buildup inside the roof space. This type of membrane allows air to circulate, which helps to prevent condensation and dampness. It is usually made from a combination of polypropylene and polyethene, which are both lightweight and durable materials. Breathable membrane is typically installed between the roof tiles or slates and the insulation, and it can also be used as a waterproof layer to protect the roof from rainwater.

Multi-foil over rafter, on the other hand, is a type of insulation that is installed above the roof rafters. This insulation is made up of multiple layers of reflective foil, which reflect heat back into the room below. The multi-foil insulation is designed to be used in conjunction with other types of insulation, such as mineral wool or foam, to create a complete insulation system.

When used together, breathable membrane and multi-foil over rafter can provide an effective insulation solution for roofs. The breathable membrane helps to prevent moisture buildup inside the roof space, while the multi-foil insulation helps to keep the heat inside the room. This combination can help to reduce energy bills and improve the comfort of the building.

Breathable membrane and multi-foil under rafter are two different types of roofing systems that can be used to insulate a roof and prevent heat loss.

Breathable membrane is a material that is installed on the underside of the roof, directly above the insulation layer. This type of membrane allows air to circulate, which helps to prevent condensation and dampness. It is usually made from a combination of polypropylene and polyethene, which are both lightweight and durable materials. Breathable membrane is typically installed between the insulation layer and the ceiling, and it can also be used as a waterproof layer to protect the insulation from rainwater.

Multi-foil under rafter, on the other hand, is a type of insulation that is installed below the roof rafters. This insulation is made up of multiple layers of reflective foil, which reflect heat back into the room below. The multi-foil insulation is designed to be used in conjunction with other types of insulation, such as mineral wool or foam, to create a complete insulation system.

When used together, breathable membrane and multi-foil under rafter can provide an effective insulation solution for roofs. The breathable membrane helps to prevent moisture buildup inside the roof space, while the multi-foil insulation helps to keep the heat inside the room. This combination can help to reduce energy bills and improve the comfort of the building.

Multi-foil between rafter is a type of roofing insulation that is installed in the space between the roof rafters. This insulation is made up of multiple layers of reflective foil, which reflect heat back into the room below.

The multi-foil insulation is designed to be used in conjunction with other types of insulation, such as mineral wool or foam, to create a complete insulation system.

To install multi-foil insulation between the rafters, the insulation is cut to fit snugly between the rafters and held in place with staples or special clips.

The reflective foil layers face inward toward the room to reflect the heat back into the room, while the outer layers of the insulation help to reduce heat loss through conduction.

Multi-foil between-rafter insulation can be an effective way to insulate a roof and reduce energy bills.

The reflective layers of foil help to reflect heat back into the room, while the layers of insulation help to reduce heat loss through conduction.

This combination can help to keep the building warm in winter and cool in summer and improve overall comfort levels.
