Excellent thermal properties

Integral DPC

Application:

ARC Insulated DPC is a thermal cavity closer 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. The polyethylene foam insulation will help prevent cold bridging and eliminate moisture, mould and staining from around windows and doors, while the DPC is embossed to assist mortar adhesion. The person installing the Insulated DPC should first familiarise themselves with the datasheet, ensuring the correct product is being fitted into the cavity.

Installation instructions

ARC Insulated DPC is easily installed as the brickwork progresses and before the window or door is fitted. The DPC should sit against the inner side of the outer brickwork to prevent moisture pentration. When joining it is recommended to lap the DPC by at least 100mm and to ensure the insulation is tightly butted with no breaks.

FAQ’s

Can I buy the Insulated DPC in different sized rolls?

The ARC Insulated DPC is designed to insulate the void between a return block and external brick, and is supplied in 10m rolls which are suitable for a 17mm void. Two widths are available, to suit 100mm or 140mm block width.

Is the ARC Insulated DPC fire rated?

The ARC Insulated DPC is suitable for minimising cold bridging in applications where a fire rating is not required. If you require a fire rated cavity closer, please see the ARC Rockfibre Insulated DPC.

What is the ARC Insulated DPC insulated with?

The ARC Flexi-Closer is insulated with polyethylene foam.
