Rockfibre Insulated DPC is designed to close the cavity around window and door reveals in conjunction with a return block, fitting between the return block and inner edge of the outer skin of brickwork:

Cavity Closure: The Rockfibre Insulated DPC effectively seals the cavity between the return block and the inner edge of the outer skin of brickwork. This closure is essential for preventing drafts, moisture ingress, and thermal bridging, which can otherwise compromise the building's energy efficiency and comfort levels.

Thermal Insulation: By closing the cavity around window and door reveals, the Rockfibre Insulated DPC helps to reduce heat loss through these critical junctions. This enhances the overall thermal performance of the building, contributing to improved energy efficiency and reducing heating and cooling costs.

Moisture Protection: The insulated DPC acts as a barrier against moisture, preventing water from penetrating the cavity and causing damage to the building structure. This is particularly important in areas around windows and doors, where moisture ingress can lead to dampness, mould, and deterioration of materials.

Compatibility with Return Blocks: Designed to fit between the return block and the inner edge of the outer skin of brickwork, the Rockfibre Insulated DPC ensures a snug fit that enhances the seal around window and door reveals. This compatibility simplifies installation and ensures that the cavity is effectively closed, maintaining the integrity of the building envelope.

Durability: The use of rockfibre in the insulated DPC provides a robust and durable solution that can withstand the environmental stresses encountered in these exposed areas of the building. This durability ensures long-term performance and reliability.

What is Rockfibre Insulated DPC?

Rockfibre Insulated DPC (Damp Proof Course) is a building product designed to provide a barrier against moisture and cold bridging in construction projects. It combines the thermal properties of rockfibre insulation with a damp-proof membrane to protect walls and other structural elements.

What materials are used in Rockfibre Insulated DPC?

Rockfibre Insulated DPC is made from high-density rock wool, which is bonded to a durable damp-proof membrane. This combination ensures both thermal insulation and moisture resistance.

How is Rockfibre Insulated DPC installed?

Rockfibre Insulated DPC is typically installed within wall cavities, around windows, and at junctions where moisture or cold bridging might occur. It can be easily cut to size on-site and is installed alongside other insulation and damp-proofing measures.

What are the key benefits of using Rockfibre Insulated DPC?

Rockfibre Insulated DPC offers excellent moisture resistance, preventing damp from penetrating the structure. It also provides thermal insulation, reducing cold bridging and improving the overall energy efficiency of the building.
