FrameFit Low Modulus Spacer Profiles

FrameFit is a new product range of materials designed to narrow the gaps on fire doors which do not meet the gap thickness requirements set out by UK building regulations.

The FrameFit Low Modulus spacer profiles are designed to be used on the sides and head of the frame, if the gap between the frame and the door is greater than 4mm.

Ensure you pick the correct thickness product(s), so that the gap does not go under 2mm.

FrameFit bottom door seals need to be installed with FrameFit Low Modulus.

Sizes

All FrameFit door frame rolls are 5.2m long.

For FD30 doors, choose the 44mm wide strips. For FD60 doors, choose the 54mm wide strips.

Doors must be a minimum of 44mm thick for the FD30 strips and 54mm thick for the FD60 strips.

The strips come in the following thicknesses: 1.5mm, 3mm and 5mm.

They can be used to close gaps which are up to 15mm wide down to the 2mm to 4mm requirement.

Multiple strips can be used in conjunction with each other to achieve the reduction of gaps larger than 9mm.

FrameFit Low Modulus (LM) strips can be used in conjunction with both the FrameFit High Expansion fire and smoke seals and it is required when installing the bottom door seal.

When used by itself, FrameFit low modulus should be doubled up with an intumescent strip in the door.
