Whether you want to renovate or replace, we can help you with your timber casement window project.

 

Ventrolla’s two-part process begins with the treatment and renovation of the timber casement window; the second part involves upgrading the performance by draught-proofing the window using the unique Ventrolla Perimeter Sealing System (VPSS). All work is carried out internally where possible, reducing the need for scaffolding.

 

The Ventrolla Perimeter Sealing System (VPSS) is installed into either the frame of the casement window or the sash itself (depending upon the construction of the casement window). If appropriate, the system can be installed into staff bead around the frame. The pile carrier is routed into the timber giving a permanent fixing point and making the system an integral part of the window.

 

Ventrolla Wood Repair:

 

Ventrolla wood repairs are undertaken using Ventrolla VR90, formulated to give long-lasting wood repairs beyond those normally carried out using conventional polyester wood fillers. VR90 is a patented two-part resin system and is designed to impart the original strength to tenon joints, fill gaps/joints and is moulded to match the window profile. It completely bonds with the parent wood and flexes when the wood contracts or expands. To achieve this bond, all decayed wood is removed exposing only sound wood. This is then stabilized using VR90 WS solution which penetrates the wood fibres to attain the permanent anchorage for the subsequently applied VR90 filler.

 

Ventrolla Perimeter Sealing System (VPSS) performance:

  • Air permeability: To BS EN 12207 Class 3 and BS 6375: 1-2009 (600 Pa) to withstand 71 mph winds, independently assessed by the British Board of Agrément (test report number 2756).
  • Draught strips: Tested to BS 7386.
  • Sound insulation: Independently tested and proven to fall within the 6–10 dB noise reduction range. Performance verified by Hanns Tucker Acoustic Engineers.

 

Features and benefits:

  • Replacement windows consume up to 40 times the energy of renovation.
  • Renovation retains the invested energy within the original window.
  • Minimal waste is sent for recycling or to landfill.
  • Window energy rating is improved by 30%.
