Air Test

If your building exceeds a certain size, or is a domestic property, you can't hand it over to the client without a valid air leakage test certificate. Part L of the Buildings Regulations requires that all buildings that are not dwellings, and that have a gross floor area greater than 500m2, be subject to a mandatory air permeability test. L2 requires that for domestic dwellings a representative sample of houses (in a development) be tested. A1 Sealants are experienced in sealing for air tests - call us for more details.

Block & Wall Joints

Joint sealants function as an integral component of the building envelope, protecting the structure from damaging moisture ingress caused by wind, gravity, capillary force, surface tension, and air pressure differentials. While they only constitute a small percentage of a construction budget, joint sealants and other waterproofing-related issues are responsible for a majority of post-construction complaints and requests for retrofits. Poorly designed, manufactured or installed joint sealants often need to be replaced in as few as two to five years after construction, at a considerable cost to stakeholders.

Bath, Kitchen Sanitary & Wet Areas

These products contains a powerful anti-fungicide to prevent mould growth, and can be overpainted. Their added benefits include permanently flexibility, adheres to most surfaces, mould resistant, overpaintable, easy clean up by wiping with a wet cloth.

Acoustic Sound Proofing

Acoustic Sealant is a high quality water borne intumescent sealant, which also provides excellent acoustic properties. Its non-drying and non-hardening characteristics allow it to retain its acoustic properties over time.

One Part / Two Part

Speciality one part and two part silicone adhesive systems offer flexible adhesive traits together with the aptitude to withstand high temperatures, resistance to water and superb electrical insulation properties. Silicone compounds are applied for adhesive bonding to glass, plastics, metals and rubber substrates.

Windows & Door Frames

Protect window and door frame sealant provides a superior performance siliconised polyurethane sealant for sealing metal, wood and uPVC frames, cladding and plastic sheeting.

Saw Cuts / Floor Joints

Joint sealants are an important part of protecting joints in concrete floors. Whether the joint is saw-induced (saw-cut) or a formed construction joint (armoured joint), filling the gap with a sealant helps to support the joint and prevent arris damage.

Joist Ends

Provides a fast and effective solution to reduce air leakage through ‘pocket masonry’ in block wall. Once installed, it removes the need for mastic sealant around the perimeter of joists.

Expansion / Contraction Joints

All concrete, once placed, will contract slightly during the curing process; this is the primary cause of small surface cracks that appear during the curing process. When set, concrete will expand and/or contract slightly with ambient temperature.


A sealant specifically developed for use for grouting and sealing around sanitary ware and fixings to give anti pick and anti vandalism joints such as in HM prisons. It is also suitable for use in perimeter sealing of doors and windows as well as heavy duty joints in floors and walls.

Glass to Glass

Glass sealant is a high performance, one-part silicone sealant that offers excellent adhesion (usually without a primer), weatherability, elasticity and long life reliability for glazing.

Curtain Walls

The application of curtain wall sealant greatly reduces the air and moisture permeation as well as reduces energy loss around the perimeter of the curtainwall.


Tank sealant is a corrosion resistant composite for the internal coating of rusty and corroded steel petrol tanks and stops leaks from 'pinholes'.

Clean Rooms

Used for sealing on floors, walls, ceilings and window frames of the clean room and around light fittings and installation units.

Swimming Pools

We use sealant that has been specifically designed for use in the installation, maintenance & repair of swimming pools, hot tubs & jucuzzies. This sealant has special properties of being resistant to the Chlorine level required for swimming pool disinfectation, non-corrosive, UV resistant & high adhesive strength to many substrates.

Lead Work Joints

Specifically designed for pointing joints between Lead and masonry or brickwork. Lead Pointing Sealant is a low modular neutral cure silicone sealant which gives a permanent, flexible, waterproof joint that can withstand the different rates of thermal movement of Lead and masonry during fluctuations in temperature changes.

Intumescent Fire Seal

Designed to help prevent the spread of fire and smoke throughout a building, intumescent sealant will swell on exposure to extreme temperatures to create an effective barrier to flames and smoke. Intumescent sealant is generally applied to fire doors, windows, cables, pipes, joints, voids and other small holes through which fire could potentially spread. Investing in our services for your premises is a highly effective way to protect your building in the event of a fire, and could significantly reduce the damage that a fire can cause.
