Mullions

Lightweight and robust, with the flextural strength almost three times stronger than cast concrete, Capvond's Cast Composite mullions are fast and easily fitted. Our range of Mullions can be supplied in stone finishes with mixed colour detailing, RAL or B.S colours or in our base colour of grey, for painting on site. Mullion sizes can be produced to customers individual requirements or produced from standard stock mould sizes from our growing mullion range.

All our mullions are within the safe lifting weight for one person.

Door surrounds, window surrounds, mock lintels and quoins

Door surrounds, mock lintels and window surrounds can be manufactured as stepped quoins or in a 90 deg façade detail. As with all our Cast Composite products, lintels, door features and window feature framing can be manufactured in traditional stone colours with multiple colours within the detailing.

Lintels, door surrounds and window surrounds are also available in all RAL or B.S colours or in our base colour of grey for overpainting alternatively our natural stone finishes with mixed colour detailing are available in buff and red sandstone, portland stone, concrete grey and anthracite.

We are happy to match, as closely as possible, samples provided by clients.

All our Cast Composite building mouldings will take screw fixings directly into the product. For larger screws and screw fixings close to an edge, a smaller pilot hole should be drilled first.

Stainless steel fixing plates are pre fitted as required. These small plates help to provide support for larger items, and items such as mock lintels which could move during istallation. We recommend that together with mechanical fixing with the plates, good quality bonding mastic is also used to adhere the products to the substrate.

Our advisors are available to assist with any fixing details.

FAST FIT - CLEAN LINES - NO CHIPS OR BREAKS - WIPE OFF EXCESS MORTAR WITHOUT STAINING!


Cast Composite Mock Lintels

Sharp, square corners provide clean finished lines, and as these products are 95% cured within 24 hours of manufacture, they will not arrive on site with chips or friable edges.

Radiused or champhered corners are manufactured with the same resillience and sharp detail.

Cast Composite Window Surrounds

SIMPLE TO FIT: Smaller items can be simply bonded to block, brick concrete or timber using external quality grip mastics.

Cast Composite Mock Lintels

ADDITIONAL SUPPORT: Larger products such as mock lintels (above) which require support during fitting or products fitted in locations of extreme weather can also be fitted using mechanical fixings and small stainless steel plates together with exterior grade bonding mastics. These plates are factory fitted to the Cast Composite mouldings prior to delivery. Filler packs, identical to the material used in the production of the product, are supplied to cover the countersunk fixings, or screw holes if fixings are removed once the bonding has fully cured.

NO STAINING: As Capvond's Cast Composite products have only 0.2% porosity, mortar is simply wiped off when soft or gently rubbed off when hard, leaving no stains or permeation into the sill, quoin, lintel, window or door surround There is no need for painting or specialised cleaning once the the exterior finishes have been completed.

SOLID COLOUR: All brick, stone and base colour copes, mullions, lintels, sills, quoins, door and window surrounds are coloured throughout the Cast Composite moulding allowing them to be machined yet still retain the same colour as the surface.
