GRP Enclosures

Industrial GRP design and manufacture a huge range of GRP Enclosures to provide housing solutions for a range of different applications. These robust and fully weatherproof GRP Enclosures are available in any size configuration, are rated up to IP65, and also provide excellent chemical resistance.

GRP Enclosures – Structural Design

All GRP Enclosures are designed in accordance with current legislation and European and British Standards.

Thermal Properties

Standard GRP Enclosure construction will provide an insulation U value of 2.2 W/m2/C. Increased levels of insulation up to 0.3 W/m2/C could be attained by integrating encapsulated foam pads into the construction.

Ventilation & Air Conditioning

Different levels of natural ventilation are available as integral parts of the GRP Enclosure wall or roof. There are many types of vents currently offered: stainless steel louvre vents, uPVC brick vents, aluminium powder coated louvre vents, all supplied with internal screens. Forced ventilation can be incorporated using fans or air conditioning. External GRP weatherproof cowls can also be fitted where required. Further details and design calculations on natural and forced ventilation can be obtained from our design team.

Integral Floors

A comprehensive range of floor options are currently available. GRP single membrane floors for small GRP Enclosures, composite load bearing floors and steel sub-frames for larger GRP Enclosures. All steel sub-frames are produced in our in-house steel fabrication department, and are supplied as standard with certified integral lifting points, shot blast, zinc primed and painted to BS5493 Table 3 Part 3.
