Openlam: The wood openwork cladding

The complete solution for the external cladding

Thanks to 25 years of experience in manufacturing wood components, we offer for your construction or renovation project, the complete solution for the external cladding: solid timber cladding, timber open work style cladding and window and door casings

In order to ensure better sustainability of the outer shell, we have designed and developed an exclusive line of window and door casings for your home. These solve all air & water sealing problems as well as enhancing your home’s exterior.

Trimmed for longevity, our cladding Openlam® and our casings give your home a stylish, air & water resistant outer skin in all extreme weather conditions.

The quality of SIMONIN timber cladding

In order to supply an aesthetic and reliable product, one of its kind, our team pays tremendous attention to each and every detail of our external cladding. Our wooden cladding will perfectly match your timber construction, whether timber framed house or wooden extension.

Supply of high-quality timber

All woods used in the manufacture of our cladding are from certified sustainable forests PEFC or FSC.

Spruce

Our woods are selected from colder regions, where they are slower grown and have a fine grain. All the natural defects are removed during manufacturing. To ensure a beautiful visual appeal, our cladding will only contain small sound knots; the natural variation of the grain of our timber resembles flames highlighting the natural characteristics of the timber. We choose naturally resistant softwood, Spruce. Spruce takes paint particularly well. The Spruce is brushed to emphasise the grain and then three layers of acrylic paint is applied to increase the longevity of the cladding.

Larch

Our selection process of arch is identical to the above, we choose high-quality wood. For this, larch exclusively comes from Switzerland or Austria.  Using the same manufacturing process as the spruce siding , the larch is purged of all defects and sapwood. Naturally resistant (class 3), it can be installed without any treatment and without any finishing.

Various styles of installation: vertical, horizontal, inclined

Wood selection – finger jointing

  • sorting and purging of irregularities
  • no waste: 100% usable
  • optimum stability and durability

Brushing (on Openlam®)

  • supersedes the natural erosion
  • improved paint adherence

Invisible fastening

  • pre-drilling of every board
  • precision nail setting
  • no risk of splitting
  • fast and easy workability

Factory milled end cuts

  • continuous installation

High-End finish

  • class 3 anti-termite treatment
  • stained or painted
  • mechanical processing

The easily installed cladding

The careful and selective sorting of the timber ensures straightness and easy fitting of each board. Time saving in the implementation is significant and loss is minimized.

For all types of construction and renovation

The Simonin range applies to all types of construction and renovation. The great flexibility of installation makes it possible to adapt to all architectural styles.

Paint and Woodstain ranges

Our range of acrylic paints

The paint we use has a satin appearance, it’s based on acrylic resin and is specifically designed for exterior wood. It has excellent adhesion while remaining flexible. The coating is highly resistant against abrasion and has water-repellent properties.

On the front the spruce Openlam® profiles get a layer of acrylic primer and two coats of acrylic paint with denibbing between each layer. A layer of acrylic primer is applied on the back.

The painting is done on an industrial scale with high performance technical means. This powerful technical equipment such as an automatic paint line and a drying tunnel guarantees a very regular application. This method applies 3 – 4 times more paint than a manual application and gives the product a much higher resistance.

We offer 10 standard shades in acrylic paint. According to quantities it is also possible to choose from a number of more than 1000 shades to paint your individual cladding.

Our range of Woodstains

The water-based Woodstain we use is a product specially designed for the protection of exterior woods commonly used in joinery and cladding. It provides a non-film-forming protection on exterior cladding and joinery and gives your facades a uniform finish, with a pre-weathered look. This limits humidity exchange.

The woodstain is a non film-forming product, this prevents the peeling of the protective layer.

Matt and resembling wood.

Gray timber cladding easy to maintain.

We offer 3 standard colours which are applicable to our spruce and larch cladding.

Bardage saturateurBardage saturateur

Our range of woodstain for spruce and larch

The stain allows to keep the colour WOOD.

The 3 layer manufacturing process used for the paint is identic to the one of the stain

First a layer of UV protection, followed by two coats of acrylic stain with denibbing between each layer. The back receives a waterproof layer to ensure against-swing.

Two colours of stain are available for spruce and one for larch.

Slight differences in color may appear between samples of woodstain and different productions.

Some finished projects

Fire regulations : the solution for your projects

The fire regulations provide obligations in terms of spread of flame for exterior cladding in certain cases.

The Class 1 (UK) or (Euroclasse C, s1, d0) spread of flames classification is requested on many projects.

On what types of buildings is an M2 cladding required?

  • facades with windows and which do not comply with the rules C + D (obstacle to the passage of fire)
  • with a floor and sleeping area
  • with at least two floors

Residential buildings

  • Ground floor of 4-7 floor buildings
  • if they are too close together (ratio B / H <0.8) and for all levels of the facade

To meet these requirements we offer : larch cladding (Openlam 21×120) – Euroclasse C,s1, d0 (M2)

Details and advises/recommendations for installation

The Openlam® cladding combined with the exclusive casings for openings ensure the durability of the structure. An installation according to the national standards and the care given to each detail determine the quality of a cladding.

Ensure good ventilation

  • Use battens of minimum 27 mm thickness (or more) to improve air circulation behind the cladding.
  • The presence of the top and bottom ventilation.

The bottom and top of the walls must not be obstructed and must have an insect grid.

The constant upward air flow prevents the stagnation of heat and humidity on the back of the cladding (summer comfort).

To ensure the tightness

We recommend the installation of our casings on openings. Adaptable to all our sidings, they guarantee water-and air-tightness

It is important to treat and paint the ends of each profile (when cutting on site). We recommend the use of our incoming and outgoing angle profiles.

Avoid contact of the profile ends with another piece of timber, there must be kept an air gap in the joint.

Provide a suitable breather membrane

Wood fiber as thermal insulation from the outside ensures the role of breather membrane.

Respect the distance to the ground

In order to ensure the sustainability of the work, the siding must be at least 20 cm above the ground.

Prevent the development of vegetation near the cladding.

Horizontal leveling

Tracing on the supports every 120 or 190 mm keeps the entire periphery of the building aligned, each level of cladding board avoiding the dispersion of dimensions.

Fasten with stainless steel nails

The fastening must be done with stainless steel nails. The thickness of the battens should be adapted to the length of the nails and the penetration comply with regulations.

Détail de principe “drainant”

Nota : Le confort d’été peut être amélioré en augmentant l’épaisseur du lambourdage (ex : 40 mm) qui supporte le bardage et en augmentant la taille des entrées et sorties d’air, qui favorisent la bonne ventilation.

Attention : La ventilation ne doit en aucun cas être obstruée pendant et après la mise en oeuvre du bardage. (exemple : chute de gravats derrière le bardage, pare-pluie ou bande d’arase qui recouvre les grilles…)
