Specialist Casement Window Renovation and Performance Upgrade

Finish:

Exposed bare wood is painted with white acrylic primer to BS 5082.

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 British Board of Agrément (test report number 2756).

• Draught strips: Tested to BS 7386.
