Description

Did you know that a home can loose 25% of its heat through the roof ? Even when your loft is insulated, if your loft stairs isn’t, then you could be loosing heat upwards. Poor airtightness sealing around loft hatches can result in the ‘chimney effect’ where warm air is drawn up into an unheated loft space. The PHS Loft Stairs Insulation Kit combines high thermal insulation with airtightness technology to dramatically reduce heat loss through your loft stairs, sealing the area and making your home more energy efficient.

Features & Benefits

  • Triple radiant fabric helps retain heat in your home
  • Airtight to eliminate draughts through your loft stairs
  • Flexible and lightweight
  • Heavy duty zippers
  • Easy to install

Installation

  • Stapling: Install the attic opening insulation cover by stapling through the black band to the rough framed opening (usually 2×6’s) above the 1×4 stair frame.

  • Orientation: Locating the zipper opening closer to the attic stair hinge will allow for easier attic access.

  • Air Sealing: Apply a bead of foam sealant or caulk between the Cover’s walls and the wood framing from the attic side to ensure a good air tight seal.

  • Larger Voids: Use our single component foam sealant to insulate attic stairs by sealing larger gaps and voids between Hatchway™ attic access door insulation and framing members.
