Metal Frame EWI External Wall Insulation (Insulated Render) can easily be applied to metal framed buildings. GPD Contracts regularly install EWI to projects that involve metal framed construction in Worcester, Birmingham, Manchester and London.
Essentially the insulated render system is adhered & fixed to a suitable sheathing board. Non combustible rating is comfortably achieved with Mineral Wool Insulation (Rockwool) with a Class O rated sheathing board, such as magnesium oxide board.
There are a wide range of finishes available including ‘through colour’ silicone & acrylic, scratch render ‘through colour’ finish, brick effect, brick slip & aggregate dash – all in a wide range of colours.
EWI systems that are available from our suppliers come with a British Board of Aggrement certificate (BBA) and a 10 year warranty.
Sand & Cement render often results in premature cracking or in severe cases complete failure, including de-lamination.
The images show a weak sand & cement mix that resulted in crumbling render and cracks, with paint delaminating and peeling off. On the right of the image it illustrates the finished silicone 1.5mm render texture.
Cracks can be repaired and re-building of areas can be made where render had crumbled.
Here it’s possible to re-enforce render, before the full ‘Scrim & Pin’ thin coat ‘re-enforced through colour render system’.
We would be pleased to provide a detailed specification to help resolve your re-render enquiry.
Brick slips are simply slips cut from actual bricks. A synthetic alternative is also readily available.
Full range of brick colours and finishes are available to satisfy planning and design requirements.
The existing wall receives base coat, re-enforcing mesh and finished to a scratch coat before brick slips are adhered.
The finishing process is pointing as with traditional brickwork, however there are a number of mortar colours available to suit job specific requirements.
Brick-effect can also be applied to re-enforced base coats.
Our experienced applicators use techniques to re-create the natural colouring of many brick types.
For thin coat renders, numerous finishes are available.
With silicone or acrylic ‘through colour’, it means that the finishing coat is coloured. Painting is therefore not required.
Silicone systems are extremely durable and washable and a multitude of colour options are available.
Commonly specified 1.5mm textured silicone finish is also available in 2mm & 3mm textures.
The images below show a selection of colour renders available from both Weber and Wetherby.
