Plasterboard for integral garages and garage conversions

As the materials stored in garages are flammable, integral garages are subject to additional building regulations. Siniat’s GTEC Fire Board provides twice the protection to walls and ceilings compared to standard plasterboard.

If you are converting a garage into liveable accommodation, you will need to consider additional thermal insulation, sound insulation and vapour resistance.

As energy prices and declining natural resources continue to impact on our lives, effective insulation is more important than ever.

The UK Government states reasonable provisions should be made to comply with regulations to improve thermal efficiency of areas including walls, floors and roof spaces.

Thermal efficiency is expressed as a U-Value. Though the calculation of U-Values can be complex our Technical Services department can calculate this for you. Call  01275 377 789 for further details.

  • Dot and Dab
  • Drylining 
  • Metal stud or timber partition


  • A range of thermal property boards available to meet your specific needs.
  • Up to 46 times thermal improvement over standard board
  • Up to 37% saving on energy costs
  • Warmer in the winter, cooler in the summer

Key Specifications

EPS Board: Available in 4 thicknesses from 22mm - 50mm
XP Board: Available in 3 thicknesses from 27mm - 55mm
PIR Board: Available in 5 thicknesses from 37.5mm - 82.5mm
Thermal K Board: Available in 5 thicknesses from 30mm - 70mm

Garage Fire Board installation

Simon Wigley, Homeowner, Dundee, Angus

“Instead of moving house, we decided to create an extension on top of our in-built garage, to use as a playroom for the kids.

A garage is a potential fire hazard and there are strict building regulations on these types of build. Our builder recommended Siniat’s Fire Board for the project and gave me the technical documentation to support his choice of brand.

The kids are very happy with their new playroom, and I can sleep easy in the knowledge that my family are safe and sound in their beds.
