Suitable for a variety of purposes as general purpose insulation blanket. Also available laminated to a variety of facing boards (e.g. plasterboard, magnesium oxide, plywood) or as encapsulated, self-adhesive cold bridge strips.


Spacetherm is fibrous blanket impregnated with silica aerogel, which can be laminated to a selection of plasterboard, MgO and plywood materials. It can also be supplied on its own in sheet form and is suitable for use internally where low U-values are required but space is limited.

Spacetherm A1 is a glass fibre blanket impregnated with silica aerogel producing a highly thermally efficient insulation which surpasses most insulations, mineral and rigid. Spacetherm A1 Blanket can be installed in layers, using mechanical fixings such as stickpins, to achieve required thermal performance or overall thickness. As it is A1-Rated, it is considered incombustible and can be used where mineral wool may be too great a thickness to employ.

Features and benefits:

  • Ultra low thermal conductivity of 0.015 W/mK (Standard)
  • A1-Rated Material thermal conductivity 0.0195 W/mK.
  • Available cut to any size or shape - contact A Proctor Group Ltd for information.
  • Available bonded to multiple finishing boards.
  • Maximum thermal performance in limited space.
  • 50 year continued thermal performance.
  • Hydrophobic nature resists water absorption.
