Here we have a selection of the Wurth consumables that we use installing Windows and Doors.
All frames are secured using 7.5 mm dia high tensile "Zebra" screws which after a pilot hole has been drilled will cut into building fabric. Available in several lengths.
Low modulas silicone sealant is used seal the outside of the frame and paintable sealant is used internally.
Any trims required to make good to the existing decoration are inc. in the quoted price and where the outside of the buildings is cement rendered any damage will be repaired as near as practical.
Where we think the installation will benefit from further fixing and or increased insulation/sound deadening we will use Wurth expanding foam. Also helps control insect ingress etc
