The Metal Access Panel - Picture Frame (Non Fire Rated) - Picture Frame is designed primarily for uses in dry lined ceiling or wall structures which serve fire protection or separation purposes. The picture frame is ideal for fitting into existing walls or ceilings.
Suitable for Part J Building Regs, which specifies the provision of access hatches to allow visual inspection of concealed flue & chimney systems.
Part J Building Regulations state that access should be at least 300 x 300 mm and should not adversely affect existing fire, thermal and acoustic provisions. (See the attached PDF by NHBC above or visit the link below direct to the 2010 Part J Regs document.)
