About this system

Suitable for application onto masonry substrates, this system uses non-combustible mineral fibre insulation (webertherm MFD) and is finished with weberwall brick, an authentic brick-effect finish available in 12 styles.

Use multiple finishes on the same project

This system can be used in conjunction with the webertherm XM silicone system (MFD) or webertherm XM acrylic system (MFD) for building designs which require a mix of brick and render finishes.

System build-up

Final finish

weberwall brick

weberwall brick is a fast fix, lightweight brick-effect façade which is suitable for internal and external use. Formulated from 95% minerals bound in cross-linked polymers, this brick system is weather resistant and flexible whilst allowing existing structures, wall systems or new buildings to freely breathe beneath its surface.EPD BBA

Substrate	U-value (110mm MFD insulation thickness)	U-value (200mm MFD insulation thickness)
Solid brickwork (215mm)	0.28W/m²K	0.17W/m²K
Solid medium dense blockwork (200mm)	0.28W/m²K	0.17W/m²K
Solid lightweight blockwork (200mm)	0.25W/m²K	0.16W/m²K
Dense concrete (200mm)	0.30W/m²K	0.18W/m²K
Brick (103mm) / Cavity (50mm) / Brick (103mm)	0.27W/m²K	0.17W/m²K
Brick (103mm) / Cavity (50mm) / Medium density blockwork (100mm)	0.27W/m²K	0.17W/m²K

Please note: If more than 200mm of insulation thickness is required, please contact us for more information.

Things to consider

For all substrates there may be a requirement to complete pull-out testing prior to any installation of external wall insulation systems.
