The SDL Avantgarde Wintergarden gives you the warm feeling of timber and a sense of being close to nature. Make the most of the great views outside whilst still being in an indoor space, protected against the weather. The roof system allows roof pitches from 5° to 45°. There is a wide choice of sustainable wood available to choose from and aluminium available in any RAL colour.

The natural wood internally gives you the warmth of timber and adds a relaxed, cosy feel to your home. The aluminium covering creates a modern aesthetic and adds durability giving you peace of mind.

System Description

Design Features

  • The load-bearing structure is manufactured using laminated spruce planks of elite surface quality and strength class BS 11 in accordance with DIN 1052-1. Specially selected, high-quality, “almost knotless” laminated planks are used for this system. Wood sourced from sustainable forestry is also available on request. The construction is designed not to transfer structural loads to the elements. All the structure’s exterior elements, such as the side rafters, the pillars in the vertical area and the exterior end-grain surfaces are covered with rear-ventilated Solarlux aluminium system profiles to protect them from the weather.
  • The laminated wooden rafters are notable for their stability and their outstanding resistance to warping and cracking. Different dimensions are used depending on the structural requirements of the project. The rafters are covered by a double-walled aluminium profile system with a continuous plastic insulation profile. The aluminium base profiles are mounted on the rafters, eaves and roof ridge. This ensures that the glazing is supported on four sides at all times. Impermeability is guaranteed by the clamping profiles, which exert a constant pressure on the double glass panes. Condensate in the base of the rebate is channelled safely into the gutter via the aluminium base profiles and rafter insulation elements. All the seals are made using a non-aging, permanently elastic EPDM material.
  • The powder-coated and rounded system profiles join together to form a harmonic unit. The design has a timeless elegance and optimum protection from the weather.
  • Roof pitches from 5° to 45° available. Wall joint allows for simple installation.
  • Designed for roof glazing thicknesses of 26 to 48 mm with glass support on 4 sides. Pane recess, glazing rebate ventilation and glazing rebate drainage comply with glass industry requirements.
  • The elements are installed against the element rebates, with the sufficient clearance from the pillars and eaves. This compensates for construction and manufacturing discrepancies.
  • The with exterior element rebates and aluminium profiles to protect them from the weather fit all element depths between 50 and 90 mm, and are installed without any internally visible screws. Wooden beams in the colour of the wintergarden next to the pillars and eaves provide the necessary interior support.
  • The mid rail that divides the glass is form-fitted between the rafters, and can transfer the load from the panes to them without any problem. The cascading drainage design ensure optimum drainage of any condensation that forms around the mid rail, eaves and wall rail.
  • The gutter joints are force-fitted with the gutter connectors for connections that fit perfectly at any angle.
  • Wintergarden ventilation via high-quality manual or electric skylights and/or dosing or roll ventilator with automatic control system, depending on customer requirements. Wood protection
  • All the edges are rounded prior to surface treatment to prevent coating from stripping off.
  • Impregnation: immersion process for spruce/fir. Colourless, quick-drying, coating-compatible impregnation agent with fungicidal properties. Properties: protects wooden surfaces from blue discolouration and rotting, penetrates very deep into the spruce, especially in the end grain. High water repellence reduces moisture absorption and significantly reduces the wood’s absorption capacity, improves the adhesion of subsequent coatings, and facilitates even wood staining with no lines or clouding when applying varnishes.
  • Priming: immersion process, wood varnish for exterior and interior surfaces. For priming and colour pre-treatment of deciduous and coniferous wooden components. Base coat for varnishing systems. Properties: water-dilutable, suitable for use in immersion, flow coating and spray coating processes, even surface effect, UV-protection, moisture regulation, extremely quick-drying, low environmental impact due to low pollutant content.
  • Intermediate treatment: spray-coating process, thick water-dilutable varnish for exterior and interior elements, silk gloss, for intermediate and final spray coating of windows and facade elements. Properties: water-dilutable, highly weatherproof, good water-vapour permeability, highly elastic, odourless.

Paul, Wiltshire

Westcott installed Velfac aluminium windows, bi-folds and external doors right across our house refurb. They were friendly, responsive and knowledgeable – and explained things in terms we could easily understand. We have no hesitation in recommending Westcott.

Lance, Farnham

I had 18 windows and doors replaced with Rationel and Westcott Construction were the recommended supplier. Josie was very helpful while we got the exact specification sorted out, and was always quick to reply on email. The fitters were very friendly and helpful, and the attention to detail was excellent. Everyone turned up when they said they would and completed the job on time. This is a very well organised company who it has been a pleasure to work with.

Jonathan, Southbrook

Right from the start once we submitted drawings, letting us know delivery dates and install which was very good and the finished product was excellent. We opted for VELFAC 200, they look great.
