MULTIFORM CONSTRUCTION
Glass Reinforced Polymer composite using a variety of core materials dependant on client’s requirements for insulation, fire ratings, security ratings and attenuation.
Structural reinforcement is included as required due to enclosure size and specific location. Housings are designed with a life expectancy in excess of 30 years.

FIRE RESISTANCE
Envcio Engineering offer half hour, one and two hour fire rated constructions, all have been independently tested. Self extinguishing resins can be used offering both 30 min and 60 min protection on surface spread of flame.
SECURITY
Envico Engineering can supply security rated products which are LPCB approved and tested to LPS 1175 by BRE, they include:
- Single and Double GRP Door Sets with multiple lock options to SR 2 and 3
- GRP Enclosures to SR 2 and 3
- Security rated ventilation options.
ENVIRONMENTAL CONTROL
Ventilation options are offered based on clients individual requirements of either heat to be dissipated or air changes needed. Information required is external ambient temperature, maximum
internal allowable temperature and heat to be dissipated. After calculations ventilation will be offered as either natural, forced or as Air Conditioning.
ELECTRICS
Envico Engineering use NICEIC electrical contractors for all electrical installations. Installations are carried out in accordance with current IEE regulations to BS7671: 2011, Zone 0, 1 or 2 installations are also available. We can install customer’s equipment if required.
EXPLOSION RELIEF
Explosion relieving roofs and panels are used to safely discharge the effect of the ignition of an inflammable mixture from within an enclosure, notably for British Gas or Regional Electric Companies. Tests have been successfully completed for both types of explosions and these conform to the relevant specifications.
