Core performance aspects

Noise Reduction

Double glazing significantly decreases external noise, creating a quieter indoor space.

Install into existing Timber frames

Insert frames are designed to literally insert into exisiting timber window frames. By removing the glass and internal timber parts, the new aluminium frames can be installed without significant building work both inside and out.

Increased Property Value

Energy-efficient upgrades can enhance your home’s market appeal.

Improved Security

Durable materials and advanced locking systems offer greater protection.
