Fillers

Nova Construction Products Limited supply a range of fillers in Polyethelene, Supaseal and VHTM material.

Foam Fillers

Precision cutting machinery produces fillers to exceptionally high levels of accuracy, optimising seals and minimising energy loss. If your requirements are more specific, we can manufacture bespoke fillers for an extensive range of settings (eaves, ridge and other roof intersections). 

Profiles

Virtually every roofing and cladding profile is held on a database and others can be quickly added. A direct reference to tooling ensures that fillers are always precision matched to sheeting panels. Sheet manufacturer name or reference can identify the correct profile or profile drawings can accurately match dimensions.

Figure 1

Flute

The choice of flute depends on which side of the profile sheet is to be filled. See Figure 1. 

Large Flute 

Typically used at the ridge, filling the inter-profile between ridge cap and corrugated roof sheet, this filler fits on top of the sheet. For a reverse profile the large flute filler goes under the sheet. 

Small Flute 

Typically used under the roof sheet at the eaves, filling the inter-profile cavity between sheet and structure, the small flute is fitted to the opposite side of the sheet compared to the large flute and fits upwards into the crown.

Self-Adhesive Fillers 

Bonded butyl sealants can be applied to the profile, the base or both, offering easier location and improved weather seal.

Base 

Large and small flute fillers are manufactured with a standard 6mm base. Extended base depth available on request. See Figure 2. 

Figure 3

Filler Angle 

Fillers to be fitted along roof hips and valleys must be cut to the angle formed by the flashing or valley and short dimension of the profiled sheet *(true angle). It must also be determined if the filler is left or right handed. See Figure 3.

*This depends on both the plan angle and pitch of the roof; we can calculate this if required.

Ventilated Fillers 

Trimmed Profile - Small Flute 

Allows condensation forming on the under side of the sheet to run down over the top of the filler.

Ventilation Channels - Large Flute 

V-shaped nicks in the foam allow condensation forming on the ridge flashing to run down over the top of the filler.

Mesh Inserts - Large & Small Flutes 

19mm mesh vents situated in the body of the flute prevent insects entering the void. See Figure 4. 

Ferrule Vents - Large & Small Flutes 

22mm ferrule vents situated in the body of the flute allow airflow. 

Fire Stop Fillers 

Made to order FIRE STOP C144 is designed to be fitted above compartment walls and into corrugations where complete resistance to fire is required.
