Insulated GRP Enclosures

A bespoke Adept Insulated GRP Enclosure would normally be constructed using a 12mm or 18mm Ply Core within a sandwich construction. A typical 12mm Ply Core Construction would provide a U Value of 2.2 W/sq.m/degC, whereas an 18mm Ply Core would provide a U Value of 1.5 W/sq.m/degC. The introduction of a 50mm Foam Slab Insulation along with the 18mm Ply Core mentioned above would provide a U Value of .45 W/sq.m/degC.

GRP Kiosks and the cold


thermalpropertiesGRPkiosksparking attendants and yard workers hate long and cold wintery spells.

Car parks are full to the brim with more people commuting to work to avoid the cold snap which is keeping attendants busy monitoring who comes and who goes but where do the attendants go for a quick break or a rest during the quieter periods? The answer is nowhere in the majority of private open plan car parks where space is optimised for parking and not buildings.
GRP Kiosks are the realistic alternative to staying out in the cold. GRP stands for glass reinforced polymer which is affordable and durable and as seen as the alternative to steel structures.

GRP Products are easily maintainable and they can also be customised or built to bespoke specifications to suit any buyer. One of these kiosks would be the perfect solution for parking attendants or yard workers who need a place to rest. By not being a permanent structure GRP kiosks can also be relocated to other locations if needed.
There are many specifications that can be added to your kiosk including thermal insulation, fire resistance, electrical installation and air conditioning so they really are an ideal solution to many building problems.

GRP Feeder Pillars for Roadside Protection


Because of the durability, waterproof and anti corrosion qualities of GRP it is a material used by many industries for the manufacturing of GRP feeder pillars.

The flexibility of GRP also enables the customer to specify exactly what he requires and GRP feeder pillars can be manufactured specifically to the customer’s satisfaction.

GRP feeder pillars are the perfect solution for many roadside appliances that need complete protection. GRP feeder pillars can be manufactured to accommodate low voltage electricity when the feeder pillars are treated with a special resin which makes them self-extinguishing and fire resistant.

GRP feeder pillars are manufactured with many different features all specified by the customers requirements. One of the most common features for the GRP feeder pillars are the lockable doors which are fitted as standard unless the customer requires a different option or extra security. There are variations on these doors like a cylinder night latch or a stainless steel hasp and staple.

Because GRP feeder pillars are consistently used to house electrical wires that continue underground they can have an open base so that the wires can be connected through an integral flange.
Then there are GRP feeder pillars that need permanent flooring and so the feeder pillar would then be fixed to a concrete base with an internal reinforced fixing flange. Wall mounted feeder pillars are also required for some customers and these are manufactured again to the specific requirements of the customer.

There are many other features that can be supplied with GRP feeder pillars it is just up to the customer’s individual requirements for this versatile product.

Housings from AdeptGRP

If your GRP Housing is located in a position where you expect it to stay for a long time then to fit in with the local environment will be an important issue when applying for planning permission.

The outside walls of GRP Housings can be designed with many finishes such as a timber effect if it was erected among trees and greenery. Or a brick and stone effect finish would suit somewhere in a town or on an industrial estate.

GRP Housings can be fitted with fire and intruder alarms and steel security doors if the customer requires this protection. GRP Housings can have integral floors or they can be mounted on to a steel sub frame.

The flexibility of the GRP material can be used in designing and constructing many custom built housings to the clients specifications. The GRP housing layout of the doors, windows and any access panels can all be tailored specifically as required.

Housings can also be constructed with environment assaults considered, this would apply to where it is constructed and what it is housing. Because of the strength and versatility of GRP many industries such as water, telecom, electrical and petrol have used GRP housings for many years.
