BUILDING AND STRUCTURAL SYSTEM

During the building of Grupo Cid homes, a mixed structural system is used with a combination of iron, wood and panels, joined together to offer a structure made up of:

  • Horizontal base for modules.
  • Vertical wall exterior facings with interior divisions.
  • Horizontal panels for ceilings.
  • Roof.

Assembly and fitting of these elements offers a resulting compact modular structure which complies with requirements for rigidity and security, necessary for its transportation and use.

1) CHARACTERISTICS AND QUALITY STANDARDS

The plywood and MD panels used in the manufacture of Grupo Cid homes comply with European regulations.

The plaster and cellulose fibre panels adhere to building regulations concerning stability and protection against fire and noise, as well as complying with Spanish building regulations.

Preventive application of a protective glaze on the wood will stop the onset of fungi, woodworm and mould, as well as providing the wood with efficient protection against the effects of the weather and UV rays, elements provided for in current legislation.
thanks to open pore techniques and the energy of the water-resistant action of the resins applied, humidity and the wood’s natural movements are regulated.

Protective systems with water-based paints are used, due to their increased elasticity and durability. They adapt to all sorts of materials by creating a protective coating which regulates humidity and offers excellent resistance against abrasion, the effects of water and permeability to water vapour, as well as against damp when condensation is present.

High density conifer and tropical woods are used and all are extremely well protected against mould, the action of fungi and rotting and against wood-eating insects.

High density polystyrene panels provide Grupo Cid homes with excellent insulation, as well as complying with all relevant legislation.

Ceramic tiles and marble aggregate blast coatings are applied using high quality adhesive pastes with excellent sticking power.

Twin component, solvent-free polyurethane glue is used, offering high resistance to peeling, breakage and fire.

Furthermore, the roof tiles used for Grupo Cid modular, pre-fabricated homes comply with all the guidelines published by the Instituto Eduardo Torroja.

2) MATERIALS

Base Platform.
  • Perimeter with modules and transversal beams, treated with anti-oxidants.
  • Solid iron, offering greater structural resistance, with anti-corrosion and anti-rust treatment, a specially important quality for homes located in damp or humid areas.
  • High resistance plywood panels with high sound-proofing insulation.
  • Flooring with first quality earthenware tiles, fitted using high resistance, quality materials.
  • The structure offers greater resistance per square metre than traditional buildings.
Outside wall panels:
  • Phenolic (Marine) plywood panels protect the exterior walls offering greater structural resistance and against impacts.
  • Fire-resistant, water-repellent panels on the inside. The main difference with other materials is that, as well as being fire-resistant, it is also water repellent and possesses great resistance against impacts.
  • Pine wood for frames, which is treated for added protection.
  • All the wood used in Grupo Cid homes is immersion treated with fungicides.
  • Rigid, high-density, polystyrene insulation, vacuum sealed onto the panels with high quality adhesives.
  • Frame with insulation which, as well as providing structural support, eliminates heat-loss as there are no joints.
  • Treatment for expansion joints, both inside and outside.
    On the inside, treatment is also applied to the joints in order to prevent structural fissures.
  • Plaster coating for marble aggregate blasting and the application of transparent fire-resistant varnish (outside).
  • Treated plywood boards for external joints. Mortar finishing or marble aggregate spray blasting, added to water-repellent varnish, also guarantees maximum protection against damp from the outside.
  • Three coat plastic-based paint inside: high quality primer sealant, plastic-based paint for splatter or pebble dash and satin-effect plastic finishing. This three stage process does not only prevent dampness, but it also allows walls to be washed down using soap and water.
  • Both bathrooms and kitchens have complete, wall-to-wall, floor-to-ceiling ceramic tiling.
  • Skirting boards are in dyed wood to match the rest of the woodwork and ceiling frames are painted white.
  • The main difference in the dividing walls compared to the market norms is in its manufacture system: during compression, all the components bond, forming a single, solid piece, thus providing greater structural resistance and a joint-free insulation system offering maximum efficiency since it prevents areas of heat-loss.
Interior room-dividing panels:
  • Fire- resistant, water-repellent panels.
  • Pine wood for frames, treated for added protection.
  • Rigid, high-density, polystyrene insulation, vacuum sealed onto the panels with high quality adhesives.
  • Treatment for expansion joints inside.
  • Three coat plastic-based paint inside: high quality primer sealant, plastic-based paint for splatter or pebble dash and satin-effect plastic finishing. This three stage process does not only prevent dampness, but it also allows walls to be washed down using soap and water.
  • Both bathrooms and kitchens have complete, wall-to-wall, floor-to-ceiling ceramic tiling.
  • Skirting boards are in dyed wood to match the rest of the woodwork and ceiling frames are painted white.
  • Inside walls have the same specifications as the outside ones, taking advantage of the extra space and greater insulation in the rooms.
Roof Module.
Flat roofing panel:
  • Panel formed using fire-resistant, water-repellent panels, treated pine-wood for added protection in frames, rigid, high-density, polystyrene insulation and extra quality MD panels, all vacuum-glued at pressure with high quality polyurethane glue.
  • Treatment for expansion joints inside.
  • Three coat plastic-based paint inside: high quality primer sealant, plastic-based paint for splatter or pebble dash and satin-effect plastic finishing. This three stage process does not only prevent dampness, but it also allows walls to be washed down using soap and water.
  • As in the cases above, the flat ceiling panels, when joined to the walls, form a powerful compact block with great structural resistance and insulating qualities.
Roof.
  • Pine wood for supports, which is treated for added protection. The supports form an air chamber for ventilation, thus preventing condensation and temperature retention.
  • Pine-wood for cross-beams, which is treated for added protection and serves to support roof tiles.
  • Pre-lacquered, texture coated steel tiles, with three stage, multi-layer covering: acrylic resin first coat, second stone aggregate granules and a third coated with fungi resistant, transparent acrylic resin.

This is a permanent element, resistant to water seepage, offering low weight and no risk from sagging. Possibility of a 30 year guarantee.

Inside doors:
  • Frames in pinewood or MD chipboard panels with protective treatment and lacquered finish.
  • Standard, flat pine-wood doors, with lacquered finish, including handle, locks and fittings.
Outside doors:
  • Pine wood for frames which is treated for added protection.
  • Treated wooden doors for the exterior, with bolts, handle and security lock.
  • Front door in Iroko wood.
Windows:
  • Selected pinewood for frames, double-vacuum varnished, following regulations.
  • Selected pinewood panels, with rubber seal and double-vacuum varnishing, complying with current regulations, including cremone bolts with 3 opening points, clear sealed-glass units with reinforced glass in bathrooms.
  • High quality windows with low-cost maintenance, since they are already double-vacuum treated and painted.
  • As they are made in wood, using a double rubber seal, heat-loss is prevented. Very low maintenance costs since they are already double-vacuum treated and painted.
  • The four fixing hinges and three opening points make these elements very secure.
  • Window shutters are made from three-layer plywood, selected and double-vacuum varnished, in compliance with regulations, with special hinges and three point espagnolettes. These are three layer panels, meaning they do not cause structural movement.
Canopies:
  • Pine wood for supports, which is treated for added protection.
  • Double treated pine-wood for the canopy front panel for added protection.
  • Pine wood frieze treated for added protection.
Kitchen Furniture:
  • The kitchen elements include a low sink unit, cooker unit and diverse storage units, depending on the distribution. All come in laminated panels with moulded doors.
  • Fitted worktop with accessories (sockets, hood, etc…)
  • Stainless steel sink unit with mixer tap, 4 burner gas stove and adjustable extractor hood.
  • Exterior smoke outlet for hood and gas stove.
Bathroom fittings:
  • Basin unit with foot, toilet bowl with low cistern and bidet, enamelled metal bath tub or polyester shower base.
  • Chrome mixer taps.

3) FITTINGS AND FIXTURE

Plumbing fittings:

All plumbing and sanitary fittings comply with current regulations. Said plumbing fitting will be based on 15mm polybutylene (PB) tubes (Terroin system). The water outlet system comes in two formats, with the WC outlet in 90mm PVC and the rest in 40mm tubes.

Plumbing accessories will be in PB and brass, depending on the application, as well as Teflon for all the metal screw fittings and metallic clamps using 15mm Fischer screws for supporting the tubes.

Hot and cold water tubes will be fitted separately, with the shortest, straightest courses possible and a minimum angle of 1% in horizontal courses, in the flow direction.
The hot water heater is not included in the plumbing work.

Said element will be fitted individually for each module, for later connecting to the mains system by the owner.

Electrical fittings:

Fitted using embedded corrugated polyamide tubing, and embedded junction boxes and switching boxes. The layouts are as specified by Low Tension norms, according to each circuit and in line with the needs of basic electrical fittings.

Circuits:
  • C1 Lighting
  • C2 General use access
  • C3 Kitchen and oven
  • C4 Washing machine, dishwasher and water heater.
  • C5 Bathroom and kitchen

The electrical system will be fitted by means of a single outlet in the lower part of the module, which will lead directly to the main protected fuse-box. The main cable will measure 10mm, for live, neutral and earth.

The general fuse box distribution will offer the possibility of cutting off indoor power with short circuit and power surge protection. Switches will be magneto-thermal, manually-operated models with 2 poles 230V and a differential of 25 A/30mA. Two pole with "Miel" or similar faceplates and boxes.

The installation conductors will be common-thread line cabling with insulation protection, for both live and neutral with protective conductor for earth. Colours: black for live, blue for neutral and yellow-green for earth. The cross section for lighting circuits will be 1.5 mm2 and 2.5 mm2 for live power sockets. In bedrooms and the living-sitting room they will be situated at a height of approximately 0.50m above the floor and in the kitchen at 1.25m. A complete earthing system will be installed using a 35mm2 diameter conduct which will be connected to all the module's metal fittings.

In all cases, the electrical installation will meet the requirements for low tension circuits, as described in Royal Decree 842/2002 of 2nd August 2002.
