The StramitZED house achieves affordable sustainability



Stramit is an internationally recognised brand. Stramit boards and panels have been used successfully for over 50 years in more than twenty countries.


Stramit panels combine a remarkable range of physical properties unmatched by any single alternative building board. They have very high strength to weight ratio, good thermal and acoustic insulation and outstanding resistance to fire.


Stramit panels are not brittle and do not crumble so they can be sawn, glued, nailed, or drilled and finished with render, plaster, paint or any number of decorative coverings.


How Stramit properties match your construction requirements


British Standards Institute BS 4046

All Stramit board is manufactured to this British Technical Standard, recognised and adhered to throughout the world. Stramit has been subjected to over 50 international tests.

Full test reports supporting any of the following claims are available on request. Just give us your details on the Contact us page.


Standard Stramit panels will accept 1100kgs loading without deformation. Panels can be used for self-supporting partitions and external walls up to 3.5 meters high without structural frames. They have ample strength for use as roof decking to support workmen.

They are resistant to termites and other vermin.

Fire resistant

Stramit panels do not harbour enough oxygen to support combustion.  Unlike other composite building panels, Stramit contains no added resins, alcohol, turps or other chemicals which produce flammable vapours.

Skim-plastered the panels are UK certified for half an hour. Flame spread Class O.

Thermal insulation

Because of its composition Stramit panels have excellent thermal insulation properties in comparison with other structural walling materials. Standard 58mm panels have a thermal conductivity of not more than K=0.102 W/mk and a thermal resistance of R=0.5882m2kW.

Sound insulation

The thickness and density of Stramit panels reduce noise level from one side to the other by an average of 35db.


The standard panel is produced to a density of 380kg per cubic meter. Stramit panels can be produced to a density varying from 150kg/m3 for heat insulation to 600kg/m3 for sound insulation.

Electrical conduits

Panels are normally produced with 22mm diameter service holes at 300mm centres to accept electrical wiring. Board can also be produced without electrical conduits. To fit electrical power outlets, a high speed router should be used for recessing and grooving.

Resistance to damage

Unlike gypsum board, Stramit panels can be handled like timber and be cut with a hand-held power saw or a hand saw with wide teeth setting. They are not easily damaged or broken in transit and can also be glued, nailed or drilled and will accept render, plaster, paint and wall paper.

Space saving

Compared with partitioning systems using brickwork, blockwork, studwork and gypsum board, Stramit panels can save considerable amounts of space.


Panels can be produced with both square or tapered edges. Standard panels are produced with recycled paper surface but specialist finishes can also be provided.

Price competitive


Stramit panels are competitive in price and in most cases offer additional benefits to gypsum sheet, plywood, chip-board and fibre board, especially when comparing installed costs and sustainability factors. Pressure on world resources will make this an increasingly important consideration.
