THE BENEFITS WE BUILD INTO EVERY IG DOOR

Through continual development of design, materials and methods of construction, IG is able to maintain its market - leading position as the UK’s foremost supplier of high performance doors. When you specify or buy an IG door, you invest in a range of built-in benefits:

CONSTRUCTION
Whether you choose a steel or glass reinforced polymer door, you get the performance to ensure long, trouble-free life. IG Original, Steel Woodgrain and Glass Reinforced Polymer doors are engineered to be dimensionally stable, putting an end to winter expansion and summer contraction. They will not warp, bow, crack or swell thanks to their method of construction, which also ensures minimal maintenance requirements.

Original and Steel Woodgrain doors are formed from two 24 gauge steel surfaces permanently bonded to a rigid polyurethane core and glued around timber stiles. The steel surfaces are galvanised both sides and factory primed as standard to ensure long-term protection against corrosion. For minimal environmental impact, the polyurethane core is CFC and HCFC free and is zero rated for ozone depletion potential. To eliminate knots and to increase strength and stability, timber stiles are finger jointed.

Glass Reinforced Polymer doors are constructed in exactly the same way with glass reinforced polymer skins replacing the steel surfaces. Tough enough to resist dents and to minimise the effect of scratches, glass reinforced polymer is completely resistant to all that the weather can throw at it.

THERMAL PERFORMANCE
With their high performance insulating cores, IG doors have outstanding thermal performance. With a U value through the door of 0.55W/m²K,IG doors have up to four times the thermal insulation of timber doors.

In addition, the doors’ construction allows most types of hinge to be used without affecting the thermal break. This means that with no inner-to-outer skin contact the thermal barrier remains intact, preventing condensation forming on the internal face of the door.

DRAUGHT PROOFING
To keep out the wind and the rain, the head and jambs of frames are fitted with high quality, compression weatherstrip. In addition, frames can be fitted with a unique, patented adjustable sill made from high quality aluminium and PVC extrusions or with a Stormguard Trimline sill. Weather sealing is further enhanced by the generous 18mm doorstop, which also helps to improve security. The result is draught proofing designed to withstand the extremes of the British climate.

GLAZING
In order to provide the maximum opportunity for creating individual entrances, IG offer a very wide range of glazing options all conforming to BS 6206 and BS 5713.

Standard sealed double-glazed units have 4mm toughened or 6mm annealed clear or obscure glass in a wide choice of designs.

The Touch of Elegance range combines timeless design with the finest quality, whilst the Touch of Colour range offers the attractiveness of traditional leaded glass in a modern form. The Touch of Silk series features a sand etched design, whilst a Georgian bar is the feature of the Touch of Brass range. The Touch of Privacy design offers a simple, convenient means of controlling light and privacy. (See IG Decorative Glazing)

DECORATION
IG Original doors are primed with a highly weather-resistant ‘baked-on’ acrylic paint ready for hand or spray finishing with good quality exterior paint.

IG Steel Woodgrain doors can be supplied with a factory-applied timber effect finish in Mahogany, Walnut or Oak, or paint finish in red, blue, green or white. IG Steel Woodgrain doors are supplied primed as standard ready for on-site finishing.

IG Glass Reinforced Polymer doors can be supplied finished in Oak, Walnut or Mahogany stain, or painted red, blue, green or white. IG Glass Reinforced Polymer doors are supplied primed as standard ready for on-site finishing.

PRE-HUNG UNITS
Factory assembled pre-hung units ensure that door and frame are perfectly matched and that all seals are completely effective. With no locks to cut on site, pre-hung units reduce on site labour costs. In addition, the loose pin hinges allows doors to be quickly and easily removed and stored safely during the construction process.

HINGES
All IG doors are fitted with high performance hinges that meet the requirements of BSEN 1935. With security interlocking in the closed position to provide resistance to physical attack, the hinges have been subjected to exhaustive testing. Fitted to a 40 kg door, they have successfully survived 200,000 operations and, with yellow zinc plating for maximum corrosion resistance, have withstood a 5% salt spray for 96 hours, ensuring that IG specification provides good security as well as long-term durability.

FRAMES
Frames are available in softwood, hardwood or PVCu. For maximum protection, softwood frames are Vac-Vac treated - a double vacuum process that ensures preservative is drawn deeply into the timber. Frames are then finished with a dual-purpose yellow primer ready for staining or painting on site. Manufactured at IG’s Cwmbran facility, frames can be readily customised to particular requirements. Sills are available in hardwood or synthetic material to choice.

BUILDING REGULATIONS - PART M
In order to comply with Part M of the Building Regulations, IG offers a special sill (see Part M Frames) and doors 845mm wide to give a clear minimum opening of 775mm (and 914mm wide to give a clear minimum opening of 850mm for local authority and housing association projects).

SECURED BY DESIGN
IG offer a range of Secured by Design doors specially designed to meet the Police Preferred Specification detailed under the scheme. These doors have been successfully tested at a UKAS accredited test laboratory for compliance with PAS 23 and PAS 24. (See Secured by Design Doors)

SERVICE
Based in Cwmbran, IG is able to service the UK through networks of technical sales representatives and maintenance engineers. Technical representatives are able to call upon the company’s technical advisory department who draw upon practical experience and expertise accumulated since 1979.
