Advantages of the Fixolite box

CSTB certified

All Fixolite boxes are certified by the CSTB.

ATec tunnel boxes →

ATec half-lintel boxes →

Light

Manufactured in 6 m lengths and made from the highest density expanded polystyrene, welded mesh reinforcement and aluminium rails.

Solid

The welded mesh and aluminium rails incorporated into the moulding ensure perfect rigidity during handling.

Excellent plaster base

Thanks to side finishes in wood fibre cement (Fibragglo), brick or primer.

Perfect lintel anchorage

The concrete in the lintel ensures that the box is perfectly anchored by entering the pockets every 30 cm. The steel mesh can be removed to complete the fixing in cases of heavy stress (corner boxes).

Economic

Thanks to mass production. What's more, a range of well-matched accessories means you can assemble them quickly and save money.

Fire-resistant

The product is classified as M1, i.e. non-flammable.

Thermal insulation

With an R value of 1.42, the Fixolite box provides thermal insulation equivalent to, if not better than, that of the windows used with it.

Acoustic insulation

The values obtained during the various tests ranged from 46 to 59 Db. See CSTB acoustic test report.

Composition of a safe

The Fixolite box is a prefabricated lintel box designed to hold a closure, made up of an inverted U-shaped expanded polystyrene shell.

5 box models

Traditional

This box is the most economical and offers good performance.

High insulation (HI)

This highly insulated box is the best performing lintel box available today. It is particularly well suited to the thermal requirements of the market.

See insulation boxes →

Reinforced

This box is used for transom openings of up to 4.5m. The CSTB requires the use of reinforcement from 1.6 m upwards.

See reinforced boxes →

Orientable Sun Shade (BSO)

This box is specially adapted for orientable sun shade. Its cutaway design means it can accommodate even the largest shutters and can be fixed to its central rail.

See BSO boxes →

Half lintel

This box is increasingly in demand from manufacturers. It is suitable for "window block" closures: monobloc systems that combine closure and shutter.

See half-lintel boxes →

4 finishes

The outer casing of each model is available in 4 finishes. The inner wall is usually made of smooth or structured polystyrene.

Polystyrene

By default, the finish is made from the same polystyrene as the shell. The wall is structured (or ribbed) for better adhesion of the finishing plaster.

Wood fibre cement

The wood-cement finish is the most popular and offers excellent plaster adhesion. The 8 mm fibreboards are glued to the wall during manufacture.

Terracotta

The terracotta finish is popular for top-of-the-range insulated enclosures, and provides a finish that matches the building's façade. The 8 mm terracotta sheets are glued to the wall during manufacture.

Primer

The primer finish saves time when finishing on site. The primer is available in a choice of grey or terracotta colours.

Nomenclature

The FIXOLITE enclosure reference is made up of the enclosure model, the type of aluminium rail and the finish.
