What an external wall system is

What an external wall system is

ULMA Wall External System are self-supporting, multi-layered closing systems which solve the complete/integral housing with acoustic and thermal insulation required in each case.
It is a light dry-mounted construction system that enables the different exterior finish layers to be installed..
ULMA External Wall System meet the requirements of the Technical Building Code as regardsfire resistance, watertightness and thermal and acoustic insulation with the relevant test having been carried out.

The fact it is a dry work allows the generation of waste at the works site to be kept to a minimum, thereby complying with the maximum sustainability criteria in a manner which is speedy, economical, efficient and flexible.
As it is a multicoat system, it performs well in terms of comfort and insulation at a cost similar to that of conventional vertical cladding, achieving far better performance in terms of implementation at the works site and ease of control.
The technology applied to our ULMA External Wall system has revolutionised building design and construction. This system provides architects as well as promotors and constructors with the best alternative to traditional construction systems for facades.

CONSTRUMAT DIPLOMA - AWARDS for Technological Innovation
This new construction system has obtained one of the 4 Diplomas attributed at the CONSTRUMAT AWARDS for Technological Innovation amongst the 74 proposals put forward.

Conditions Required

Building structure on which the Externa Wall System is supported.

The system is used as Facade Cladding to meet the relevant basic requirements of the CTE. The systemdoes not contribute to the resistance of the building structure but rather it is supported by it. The usual structures on which the system is secured areconcrete and metal. In all cases these support structures must be endowed with enough resistance and stability to withstand the stresses transmitted by the system. The anchorages of the support system must be selected in line with the purpose of the latter and the streses they are to be subjected to.

Textures

ULMA External Wall System allow the installation of different materials for your linings, creating enclosures with ventilated or unventilated chamber for the Facade.

CTE - LEED - BREEAM

The Technical Building Code requires facade cladding to meet certain performance levels in terms ofenergy savings, noise protection, hygiene, safety in the event of fire and structural safety. ULMA External Wall System fits in with these requirements by way of a detailed study and analysis of the solutions using specialised tools and their ratification by means of tests carried out at approved technological centres.

CTE - LEED - BREEAM CTE - LEED - BREEAM

ULMA External Wall System is committed to developing systems which are more environmentally friendly. Facade cladding systems based on "Light gauge steel framing" technology are classified according to Breeam certification (Building Research Establishment Environmental Assessment Methodology) as category A and A+, on a scale where E is the worst classified and A+ the best. Leed certification (Leadership in Energy and Environmental Design) does not assess the cladding as such, but rather, it rates the characteristics of the materials used in building as a whole. This is why materials are used deriving from advanced wood technology and recycled or recyclable materials.

Integral Customisation

"Our motto is toadapt to the needs of each project. This is why por we have developed the ISOLA External Wall System . This system can be adjusted to CTE requirements, bearing in mind the requirements laid down for each geographic area in terms of watertightness, wind pressure and thermal and acoustic insulation. It is a plural and precise system optimised in each requirement.


What's more, as the main panel of the dry facade, there is the possibility of including a wide range of skins: Polymer concrete, Composites Boards, HPL, metal, ceramic boards etc.”


This is why we offer aCUSTOMIZATION both of the System and of the surroundings."
