Installation Rainscreen Cladding

Aluminium Brackets and Rails – Fire Safety Information.

Our specified Rainscreen Systems BBA Assessment 09/4678 describes:

Behaviour in relation to fire — in respect of reaction to fire, the systems may be regarded as having a class 0 or ‘low risk’ surface in accordance with the national Building Regulations (see section 7). Our Aluminium Bracket and rails have a fire rating of A1 – Non combustible and offers no contribution to fire.

Rainscreen Support Systems that are safe, economic and effective.

We are experienced innovators, delivering pragmatic solutions in façade and rainscreen façade support systems, since the 1980s.

Partnering the key façade manufacturers, we provide high-quality products for the best value.

We offer rail length optimisation (off site, cut to length) and split boxes to supply precise numbers of brackets required, when they are required.

We simplify the complexity of façade and are able to support almost any genre.
Our installerfriendly systems are tried and tested.

Our safe and versatile rainscreen cladding brackets and support systems are approved and optimised for value, enabling clients to buy with complete confidence.

Ahead of the curve, we listen to our architectural, engineering and façade installation partners – anticipating ‘what next’ and delivering safe and practical solutions.

Anodisation and Polyester Powder Coating are available for both brackets and rails.

Now exporting to three continents, our reach is far and impactful.

Nvelope content is BIM level 2 compliant.

The requirements for each façade and cladding system are always different and depend on factors such as local wind loads, height of the façade, substrate being fixed to, selected cladding material and the cladding zone.
All NVELOPE cladding systems can be engineered to project specific requirements using a Project Specific document containing:

*Static calculations for both general and corner building areas.
*Component guide and list pricing.
*NBS Specification.
*3D modelled thermal point loss calculations.
*Thermal report to BR443.
*Local sales representative information.

NV1 - Vertical cladding system

NV1 is the NVELOPE back frame – vertical cladding applications Suitable as a back frame system – NV1 is suitable for face fixing / rivet fixing cladding elements to e.g. fibre cement, high-pressure laminate (HPL), ACM and metal rainscreen panels. NV1 is the basis of all NVELOPE support systems.

Manufactured from extruded aluminium alloys conforming to EN 573-3 (material) and EN 755 production standards.

British Board of Agrément (BBA) - 09/4678

NVELOPE brackets (V): allows adjustment between the face of the primary support to outer face of vertical profile. Thermal isolators: hard PVC isolator assembled as standard (located between the NVELOPE bracket and the primary structural support system).
