Tremco Illbruck Compriband: Timbermax TP450
Tremco Illbruck TP450 Compriband Timber Max
Timbermax TP450 is a soft and flexible open cell polyurethane foam, impregnated with an acrylic based, UV stabilised resin. The resin is water repellent and contains a fire retardant. The TP450 has a self-adhesive side to aid initial location and is easy to apply in any weather.
Additionally, TP450 has both thermal and acoustic insulation properties.
TP450 is an expanding sealing tape designed for use in a wide variety of movement joints up to 50mm wide and can accommodate up to 37mm of movement.
Weather tight against the most severe combinations of wind and rain, it satisfies most expectations as an external weather seal in building and civil engineering applications, with particular suitability for sealing the head and cills of windows installed in timber frame construction. Extensively tested, TP450 has a proven reputation across both the UK and Europe.

Application Instructions for Timbermax TP450 Compriband Tape
• Cut off the preliminary strip and the opening wedge at the start of the roll.
• If installing tape into a construction joint, it may be applied either horizontally or vertically (from bottom to top); however, when applying to a door or window frame the horizontal seals must be applied before the vertical ones. Tape must be applied with the adhesive side to the frame when working with fenestration but may be applied in any order when working with construction joints. In both cases, do not stretch the tape. When working in damp or cold conditions a wood wedge should be used to hold the tape in position until it is expanded. Ensure the tape is recessed by a minimum of 2 mm from the front of the joint.
• When calculating the length of tape to be fitted, add 10mm/m to the actual joint length. Be sure to measure the opening and not the window.
• At the end of a roll, cut o the tape wedge finish. Repeat the process with a new roll, making a close compressed butt connection.
• If the seal is to be weather tested using the CWCT hose test (TN41), we recommend that the tape should be allowed 7 - 10 days conditioning in the joint before testing and a minimum 25 mm wide tape should be used. Please refer to technical department for advice.
• If using TP601 Compriband e to seal the window jambs(in conjunction with TP450 Compriband Timber Max to head and cill), cut and apply the TP601 Compriband e to the full height dimension of the frame. Cut and apply the TP450 Timber Max to span the full opening width,thereby covering the cut ends of the TP601 Compriband e.Ensure that the front (external) edges of both products are positioned in the same plane to achieve a continuous seal.
• For applications where the TP450 will exceed 30mm thickness in service, the face of the tape should be covered using a suitable cover trim to improve the aesthetics and provide UV protection to the exposed tape surface.
Please Note: High temperatures accelerate tape expansion, while low temperatures delay this. At ambient temperatures above 20°C, the tape should be stored in a cool place on the construction site away from direct sunlight. A small fridge is ideal for this.
